WARNING: Do not expose the Dell PowerEdge Expandable RAID Controller (PERC) S300 adapter to liquids. To reduce risk of fire hazard, do not cover or obstruct the ventilation openings of the system in which it is installed. Do not install the controller in a zero-clearance compartment. This could result in overheating. WARNING: Do not operate the controller if it has been dropped or damaged in any way. WARNING: The controller, like every other electronic part of a system, can be damaged by static electricity. Be sure that you are properly grounded. It is recommended that you wear a grounded antistatic strap and that the system is unplugged before you install the controller. CAUTION: Cable connectors must be mated carefully with the connectors on the PERC S300 adapter. The connectors are keyed to prevent them from being inserted incorrectly. CAUTION: Ensure that the current RAID controller (if any) is not currently working on any pending tasks (such as a rebuild) before it is turned off to conduct a system upgrade. CAUTION: During a firmware update, do not reboot the system that contains the PERC S300 adaper. An update might take up to five minutes per controller. WARNING: Safety Instructions 7 SAFETY: General Observe and follow service markings: • Do not service any product except as explained in the user documentation. Opening or removing covers that are marked with a triangular symbol with a lightning bolt might expose you to electrical shock. Components inside these compartments must be serviced only by a trained service technician. • Use the product only with Dell-approved equipment. • Operate the product only from the type of external power source indicated on the electrical ratings label. If you are not sure of the type of power source required, consult your service provider or local power company. SAFETY: When Working Inside Your System Before you remove the system covers, perform the following steps in the sequence indicated. WARNING: Only trained service technicians are authorized by Dell to remove covers from the system, and access any of the internal components, unless the Dell documentation expressly states otherwise. CAUTION: To help avoid possible damage to the system board, wait five seconds after turning off the system before disconnecting the controller. 1 Turn off the system and any devices. 2 Wear grounding straps that are properly grounded before touching anything inside the system. 3 While you work, periodically touch an unpainted metal surface on the chassis to dissipate any static electricity that might harm internal components. 4 Disconnect your system and devices from their power sources. To reduce the potential of personal injury or shock, disconnect any telecommunication lines from the system. 8 WARNING: Safety Instructions In addition, take note of these safety guidelines when appropriate: • When you disconnect any cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs. If you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, make sure that both connectors are correctly oriented and aligned. • Handle the controller with care. Do not touch the components or contacts on the controller. Protecting Against Electrostatic Discharge Electrostatic discharge (ESD) events can harm electronic components inside your system. ESD, or electrostatic discharge, is the process by which static electricity can build up within a person or an object, and then discharge into another object. ESD events can harm your PERC S300 adaper, your system, and other electrical components. To prevent ESD damage, you must discharge static electricity from your body before you interact with any of the system’s internal electronic components. You can protect against ESD by touching a metal grounded object (such as an unpainted metal surface on your system’s I/O panel) before you interact with anything electronic. In addition, as you work inside the system, periodically touch an I/O connector to remove any static charge your body might have accumulated. You can also take the following steps to prevent damage from electrostatic discharge: • When unpacking the controller from its shipping carton, do not remove the controller from the antistatic packing material until you are ready to install it. Just before unwrapping the antistatic package, be sure to discharge static electricity from your body. • Handle all electrostatic sensitive components in a static-safe area. If possible, use anti-static floor pads and work bench pads.

16 Overview About RAID A RAID disk array is a group of independent physical disks that provides high performance by increasing the number of drives used for saving and accessing data. A RAID disk subsystem improves I/O performance and data availability. The physical disks appear to the host system either as a single storage unit or multiple logical units. Data throughput improves because several disks are accessed simultaneously. RAID systems also improve data storage availability and fault tolerance. Data loss caused by a physical disk failure can be recovered by rebuilding missing data from the remaining physical disks containing data or parity. NOTE: When a physical disk in a RAID 0 virtual disk fails, data is lost because there is no redundancy for this RAID level. However, when a physical disk in a RAID 1, RAID 5, or RAID 10 fails, data is preserved because there is redundancy with these RAID levels. Summary of RAID Levels • Volume uses available space on a single physical disk and forms a single logical volume on which data is stored. • RAID 0 uses disk striping to provide high data throughput, especially for large files in an environment that requires no data redundancy. • RAID 1 uses disk mirroring so that data written to one physical disk is simultaneously written to another physical disk. RAID 1 is good for small databases or other applications that require small capacity but also complete data redundancy. • RAID 5 uses disk striping and parity data across all physical disks (distributed parity) to provide high data throughput and data redundancy. • RAID 10 uses disk striping across two mirrored sets. It provides high data throughput and complete data redundancy. Overview 17 RAID Terminology Disk Striping Disk striping allows you to write data across multiple physical disks instead of just one physical disk. Disk striping involves partitioning each physical disk storage space into stripes of the various sizes. These stripes are interleaved in a repeated sequential manner. The part of the stripe on a single physical disk is called a stripe element. For example, in a four-disk system using only disk striping (used in RAID level 0), segment 1 is written to disk 1, segment 2 is written to disk 2, and so on. Disk striping enhances performance because multiple physical disks are accessed simultaneously, but disk striping does not provide data redundancy. Figure 2-1 shows an example of disk striping. Figure 2-1. Example of Disk Striping (RAID 0)

Stripe element 1 Stripe element 5 Stripe element 9 Disk Mirroring Stripe element 2 Stripe element 6 Stripe element 10 Stripe element 3 Stripe element 7 Stripe element 11 Stripe element 4 Stripe element 8 Stripe element 12

With mirroring (used in RAID 1), data written to one disk is simultaneously written to another disk. If one disk fails, the contents of the other disk can be used to run the system and rebuild the failed physical disk. The primary advantage of disk mirroring is that it provides 100 percent data redundancy. Because the contents of the disk are completely written to a second disk, it does not matter if one of the disks fails. Both disks contain a copy of the same data at all times. Either of the physical disks can act as the operational physical disk. Disk mirroring provides 100 percent redundancy, but is expensive because each physical disk in the system must be duplicated. Figure 2-2 shows an example of disk mirroring. 18 Overview NOTE: Mirrored physical disks improve read performance by read load balancing. NOTE: The PERC S300 controller only supports physical disks (SAS and SATA). SSD devices cannot be migrated to a PERC S300 controller. Figure 2-2. Example of Disk Mirroring (RAID 1)

Stripe element 1 Stripe element 2 Stripe element 3 Stripe element 1 Duplicated Stripe element 2 Duplicated Stripe element 3 Duplicated

Stripe element 4 Stripe element 4 Duplicated Spanned RAID Levels Spanning is a term used to describe the way in which RAID level 10 is constructed from multiple sets of simpler RAID levels. For example, a RAID 10 has multiple sets of RAID 1 disk arrays in which each RAID 1 set is considered a span. Data is then striped (as it is in RAID 0) across the RAID 1 spans to create a RAID 10 virtual disk. Parity Data Parity data is redundant data that has been generated to provide fault tolerance within certain RAID levels. In the event of a drive failure, the parity data can be used by the controller to regenerate user data. Parity data is present only for RAID 5 disk arrays. The parity data is distributed across all the physical disks in the system. If a single physical disk fails, it can be rebuilt from the parity and the data on the remaining physical disks. RAID 5 combines distributed parity with disk striping, as shown in Figure 2-3. Parity provides redundancy for one physical disk failure without duplicating the contents of entire physical disks.

NOTE: BAS, BGI, CC and OCE run only on the operating system. Table 3-1. Features of the PERC S100 controller and PERC S300 controller RAID Controller Feature Description

Automatic virtual disk rebuild Background Array Scan (BAS) Background virtual disk initialization (BGI) Rebuilds a redundant virtual disk automatically when a failure is detected, if a hot spare is assigned for this capability. Verifies and corrects correctable media errors on mirror, volume, or parity data for virtual disks. BAS starts automatically after a Virtual Disk is created while in the OS. The background initialization of a redundant virtual disk creates the parity data that allows the virtual disk to maintain its redundant data and survive a physical disk failure. Because background initialization helps the controller to identify and correct problems that might occur with the redundant data at a later time, background initialization is similar to a consistency check. Background initialization allows a redundant virtual disk to be used immediately. Data is lost if a physical disk fails before the completion of a BGI. NOTE: Although a BGI is software-initiated at the PERC Virtual Disk Management utility, the PERC S100 adapter/PERC S300 adapter drivers must be loaded before the BGI runs. NOTE: Unless mentioned otherwise, the term PERC Virtual Disk Management utility refers to both the PERC S100 Virtual Disk Management utility and the PERC S300 Virtual Disk Management utility.

Features 21 Table 3-1. Features of the PERC S100 controller and PERC S300 controller (continued) RAID Controller Feature Description

Boot support for RAID levels Boot support for degraded virtual disks Cache support for virtual disks Allows boot support for Volume, RAID 0, RAID 1, RAID 5, and RAID 10. Enables the system to boot from degraded redundant virtual disks (RAID 1, RAID 5, or RAID 10). Supports these cache options: None, Read Only, Read/Write. The PERC S100 adapter or PERC S300 adapter uses part of system memory for cache.

Checkpointing Allows different types of checkpointing (background initialization, consistency check, and rebuild) to resume at the last point following a restart. After the system restarts, background checkpointing resumes at its most-recent checkpoint. Command queuing Command queuing is a command protocol used by SATA and SAS physical disks that is supported by the PERC S100 adapter and PERC S300 adapter. Command queuing allows the host to issue multiple input/output requests to a disk simultaneously. The disk can then decide in which order to process the commands to achieve maximum performance. The SATA and SAS versions of command queuing have slightly different protocols and means of handling multiple traffic requests at the same time, but the end-purposes are comparable. 22 Features Table 3-1. Features of the PERC S100 controller and PERC S300 controller (continued) RAID Controller Feature Description

Consistency check (CC) A consistency check is a background operation that verifies and corrects the mirror or parity data for fault-tolerant physical disks. It is recommended that you periodically run a consistency check on the physical disks. By default, a consistency check corrects mirror or parity inconsistencies. After the data is corrected, the data on the primary physical disk in a mirror set is assumed to be the correct data and is written to the secondary physical disk in the mirror set. A consistency check cannot be user-initiated in the PERC Virtual Disk Management utility. However, a consistency check can user-initiated when using Dell OpenManage Server Administrator Storage Management.

Disk initialization For physical disks, initialization writes metadata to the physical disk, so that the controller can use the physical disk. Fault tolerance The following fault tolerance features are available with the PERC S100 adapter and PERC S300 adapter, in order to prevent data loss in case of a failed physical disk: • Physical disk failure detection (automatic). • Virtual disk rebuild using hot spares (automatic, if the hot spare is configured for this functionality). • Parity generation and checking (RAID 5 only). • Hot-swap manual replacement of a physical disk without rebooting the system (only for systems with a backplane that allows hot-swapping). If one side of a RAID 1 (mirror) fails, data can be rebuilt by using the physical disk on the other side of the mirror. If a physical disk in RAID 5 fails, parity data exists on the remaining physical disks, which can be used to restore the data to a new, replacement physical disk configured as a hot spare. If a physical disk fails in RAID 10, the virtual disk remains functional and data is read from the surviving mirrored physical disk(s). A single disk failure in each mirrored set can be sustained, depending on how the mirrored set fails. Features 23 Table 3-1. Features of the PERC S100 controller and PERC S300 controller (continued) RAID Controller Feature Description Mirror rebuilding A broken mirror can be rebuilt after a new physical disk is inserted and the physical disk is designated as a hot spare. The system does not have to be rebooted.

Online Capacity Expansion (OCE) Physical disks (general) OCE is a process that allows you to add storage capacity to an existing virtual disk. In most cases additional storage capacity can be added without taking the system offline. However, if an additional physical disk needs to be added and the system does not support hot-swapping, the system must be turned off. OCE enables you to increase the total storage capacity of a virtual disk by integrating unused storage with the virtual disk. Data can be accessed while the physical disks are added (if a system has hot-swap capability) and while data on the virtual disk is being redistributed. For Volume and RAID 1, OCE expands the virtual disk by using the available space of the physical disks that are already members of the virtual disk. For RAID 0, RAID 5 and RAID 10, additional capacity can be attained by adding physical disks to the virtual disk. The PERC S100 adapter supports up to four SATA HDD or SSD physical disks. The PERC S300 adapter supports up to eight SAS or SATA HDD physical disks. NOTE: The physical disks in a virtual disk must be the same interface and drive type (HDD or SSD). For example, you cannot mix a SATA and SAS interface (HDD or SSD), or HDD and SSD physical disks, in the same virtual disk. A maximum of eight physical disks can be used for RAID 0 and RAID 5. A maximum of two physical disks can be used for RAID 1. A maximum of four physical disks can be used for RAID 10. If a physical disk fails during system startup, the controller identifies the failed physical disk as follows: • At the PERC Virtual Disk Management utility by highlighting the failed physical disk in a virtual disk in red.

24 Features Table 3-1. Features of the PERC S100 controller and PERC S300 controller (continued) RAID Controller Feature Description • In a brief warning at the Dell Inc. PERC S100 Controller BIOS or Dell Inc. PERC S300 Controller BIOS screen, that a virtual disk(s) were found that are Degraded and/or Failed. This alerts the user to the failed physical disk(s). • At Dell OpenManage Server Administrator Storage Management. • With a bi-color Status LED on each physical disk. The green element of the Status LED is off, while the amber element flashes on and off. NOTE: The Status LED applies only to systems with a PERC S300 adapter and a backplane that has removable physical disks. NOTE: PERC S100 adapters support HDD physical disks of capacity 2 TB and greater. Current and upcoming releases of PERC S300 adapters will only support upto 2 TB HDD physical disks .

Physical disk hot-swapping (hot-swap capability) Hot-swap (hot-plug) capability is the manual substitution of a physical disk for another one while the host system is powered on. If a system supports hot-swapping, physical disks can be plugged into a system’s backplane while the controller is operating, without causing the controller to reset. CAUTION: A physical disk can be hot-swapped from a system only if the system has a PERC S300 adapter and a backplane that supports hot-swapping. NOTE: If a system’s physical disks are accessible only when the system’s cover is removed, the physical disks cannot be hot swapped. The physical disks must be located on the backplane (behind the removable front panel) and accessible externally. NOTE: When replacing physical disks in a virtual disk that has already been created, make sure that SAS HDD physical disks are replaced with SAS HDD physical disks, that SATA HDD physical disks are replaced with SATA HDD physical disks, and that SATA SSD physical disks are replaced with SATA SSD physical disks. NOTE: When hot-swapping a physical disk, make sure that the new disk is of equal or greater capacity to the physical disk that is being replaced.

Features of the PERC S100 controller and PERC S300 controller (continued) RAID Controller Feature Description Physical disk roaming The controller supports moving a physical disk from one backplane slot or cable connection to another (on the same controller). The controller automatically recognizes the repositioned physical disk and logically places it in the proper order. WARNING: A virtual disk is lost if you perform disk roaming while an OCE is running at Storage Management. NOTE: For more information on how to open the system and add parts, see the Hardware Owner’s Manual, available on the Dell Support website at support.dell.com/manuals. Perform the following steps for physical disk roaming: NOTE: These steps do not apply to systems that have a backplane with hot-swap capability. 1 Turn off the power to the system, physical disks, and system components. 2 Disconnect the power cables from the system. 3 Move the physical disks to different slots on the backplane or to different cable connections. 4 Perform a safety check. Make sure the physical disks are inserted properly. 5 Connect the power cables and power up the system. NOTE: The controller detects the RAID configuration from the configuration data on the physical disks.

Storage port (Storport) driver support For use with Microsoft Windows Server 2003 and later, the Storport driver improves throughput and miniport driver interfaces.

Stripe size Stripe size is determined by a PERC S100 adapter/PERC S300 adapter algorithm. Stripe size cannot be configured by the user. 26 Features Table 3-1. Features of the PERC S100 controller and PERC S300 controller (continued) RAID Controller Feature Description Virtual disks (general) Up to eight virtual disks are supported. The PERC S100 adapter and PERC S300 adapter allows: • Creating virtual disks of different RAID levels on a single controller. • Creating different RAID level virtual disks on the same physical disk, to adapt each virtual disk to the I/O that it processes. • Building different virtual disks with different characteristics for different applications. The PERC S100 adapter and PERC S300 adapter does not allow: • Creating a virtual disk from a mix of different type physical disks. For example, a RAID 10 virtual disk cannot be created from two SATA-II HDD physical disks, a SAS HDD physical disk, and a SSD physical disk. All of the physical disks must be the same interface (SAS or SATA) and drive type (HDD or SSD). • Selecting a physical disk as a dedicated hot spare if the physical disk is a different type from the physical disk or disks. A virtual disk refers to data storage created by the controller from one or more physical disks. Although a virtual disk can be created from several physical disks, it is seen by the operating system as a single disk. The capacity of a virtual disk can be expanded online for any RAID level, without the operating system being rebooted. Features 27 Table 3-1. Features of the PERC S100 controller and PERC S300 controller (continued) RAID Controller Feature Description Virtual disk migration The controller supports automatic virtual disk migration from a PERC S100 adapter to a PERC S300 adapter (or vice versa). Manual intervention for migration is not required or used by the PERC S100 adapter or PERC S300 adapter. CAUTION: Before starting a virtual disk migration, power down both systems before removing or inserting the physical disks. After the migration occurs, make sure that all of the physical disks have been migrated and are present in the virtual disk. CAUTION: The virtual disk is lost if you perform a virtual disk migration during an OCE. NOTE: The PERC S100 adapter only supports SATA HDD and SATA SSD disks. SAS disks cannot be migrated with a PERC S100 adapter. NOTE: A bootable virtual disk cannot be migrated between dissimilar controllers or dissimilar system models when the system uses Microsoft Windows Server 2003 as its operating system.

Virtual disk RAID levels Virtual disk transformation Virtual disks at different RAID levels can be created. Virtual disk transformation can consist of: • Capacity expansion, using OCE (to allocate additional virtual disk space on the original physical disks or after additional physical disks are added). • Rebuilding (rebuilding data on a virtual disk consists of using an available hot spare or backup physical disk).

It inquires if you want to limit the size of the virtual disk or exceed the normal maximum size. 3 Press <Esc> to create a larger virtual disk. 4 Press the <Page Up> or the up arrow key, until the desired or maximum available size has been attained. 5 Continue with "Creating Virtual Disks" on page 51. NOTE: When physical disks of different capacities are used, the maximum size of the virtual disk is limited by the size of the physical disk with the smallest capacity. NOTE: If you want to have a bootable virtual disk, make sure that INT 13 support is enabled on the controller, as described in "Controller Options" on page 58. Deleting Virtual Disks CAUTION: Although any virtual disk in the Virtual Disks field can be deleted, including the first-listed virtual disk in the field, do not delete the first listed virtual disk. It may be the system’s bootable virtual disk. Deleting the bootable virtual disk erases the operating system and the controller drivers. CAUTION: When a physical disk is removed from a system, the current PERC S100 adapter or PERC S300 adapter configuration information (metadata) remains on the disk. If the removed physical disk causes a virtual disk to fail, and the virtual disk is then deleted and a Rescan is performed, re-inserting the physical disk causes the PERC Virtual Disk Management utility to merge the re-inserted physical disk's RAID Configuration and Management 53 configuration information with the existing configuration information. The previously deleted virtual disk re-appears in the PERC Virtual Disk Management utility. CAUTION: Make sure that all physical disks that are part of a virtual disk are in the system before you delete the virtual disk. 1 Power-up the system to start booting. 2 When prompted, press the <Ctrl><R> keys to access the PERC Virtual Disk Management utility. 3 At the Main Menu field, select Delete Virtual Disk(s). Press <Enter>. 4 Perform one of the following: • Select each virtual disk in the Virtual Disks field that you want to delete. Press <Insert> to confirm each selection. OR • Press <A> to select all virtual disks for deletion. NOTE: The text color of the selected virtual disk(s) changes to green. 5 Press <Enter>. CAUTION: A dialog box appears, describing the consequences of deleting the selected virtual disk(s). Deleting a virtual disk permanently destroys all data that is on the virtual disk, as well as the virtual disk itself. This action cannot be undone. 6 Press the <C> key to confirm the deletion. 54 RAID Configuration and Management Swapping Two Virtual Disks Use the Swap Two Virtual Disks option of the PERC Virtual Disk Management utility to arrange virtual disks in a different order. CAUTION: Do not swap the first-listed virtual disk at Virtual Disks if it is the system’s bootable virtual disk. The bootable virtual disk must always be the first listed virtual disk at Virtual Disks. Before You Begin • The Swap Two Virtual Disks option is enabled only if there is at least one initialized physical disk in the system. For example, if all the physical disks in the system are Non-Raid, the Swap Two Virtual Disks option is disabled. • It is recommended that the bootable virtual disk be a redundant virtual disk-type, such as RAID 1, RAID 5, or RAID 10, to preserve data in case a physical disk in the virtual disk fails. As required, swap that virtual disk into the first position at Virtual Disks, if it is not already virtual disk 1. See the Swap Two Virtual Disks option below. • The boot device and the boot order are user-selectable. • The swap feature is available only with the PERC Virtual Disk Management utility.

Troubleshooting 63 Warning Messages: Dell Inc. PERC S100 Adapter or Dell Inc. PERC S300 Adapter BIOS Screen The Dell Inc. PERC S100 Controller BIOS screen or Dell Inc. PERC S300 Controller BIOS screen is one of the first screens to appear during your system’s boot sequence. If the system’s virtual disks were in Normal or Ready status before a system boot, the boot sequence continues normally to the Microsoft Windows Server 2008 or Microsoft Windows Server 2003 operating system. But, if a virtual disk is in Degraded or Failed status, or if specific options in the Controller Options field were changed previously at the PERC Virtual Disk Management utility, the warning messages described in Table 7-3 through Table 7-6 appear during the boot sequence. For other issues, see Table 7-7. 64 Troubleshooting Table 7-3. Warning Messages: Dell Inc. PERC S100 or PERC S300 Adapter BIOS Warning Message Corrective Action

WARNING: Found virtual disks that are Degraded This warning message appears when at least one virtual disk is in a Degraded state and Pause if Degraded is set to ON at the PERC Virtual Disk Management utility. The following message appears after the warning is displayed: --- Press <Enter> to continue, or <CTRL><R> to enter setup --- Press <Enter> to allow the operating system to continue with the boot sequence, or press <Ctrl><R> to enter into the PERC Virtual Disk Management utility to investigate the cause of the Degraded virtual disk. To investigate the cause, check for the following: • Whether a physical disk in the virtual disk has failed or has gone offline. Check the status at the Physical Disks field. A Degraded status depends on the RAID level of the virtual disk and the number of physical disks that have failed: – For a virtual disk at RAID 1 or RAID 5, a single physical disk failure causes a Degraded status. – For a virtual disk at RAID 10, the failure of a physical disk in each of the mirror sets creates a Degraded status for the RAID 10. The failure of two physical disks in the same mirror set creates a Failed status for the RAID 10. • Whether the controller has failed, due to a firmware failure or a component failure. A failed controller causes a virtual disk not to boot. For the virtual disk to recover from Degraded status, the failed physical disk must be replaced and the virtual disk must be rebuilt, using Dell OpenManage Server Administrator Storage Management. When the rebuild operation is completed, the virtual disk status changes from Degraded to Ready. For a description of the rebuild function, see Storage Management, located on the Dell Support website at support.dell.com/manuals.

The virtual disk has lost one or more physical disks A physical disk in the virtual disk has failed or has been removed The virtual disk has lost the maximum allowable physical disks per RAID level Replace the failed physical disk(s) and restore the data from a backup storage source. • Re-install the original physical disk if it was inadvertently removed. Perform a rescan. • Check the status of the physical disks in the virtual disk. Replace any failed disk(s), if necessary. Restore the data from a backup storage source. After any change, perform a rescan to verify if the disk is still in a Failed state. One or more physical disks have failed. – If the virtual disk is non-redundant, the failure of a single physical disk can cause the virtual disk to fail. – If the virtual disk is redundant, two or more physical disks have failed and the virtual disk cannot be rebuilt. Create a new virtual disk. Restore the data from a backup storage source.

Troubleshooting 71 Table 7-10. A Virtual Disk is in a Degraded State Likely Causes to Check Corrective Actions A physical disk was removed • Install the original physical disk, if it was inadvertently removed, or replace it with a new or used physical disk. • Initialize a new physical disk. Perform a Rescan for all physical disks that are replaced. • If the physical disk was not removed, check that its cables are correctly installed.

Physical or mechanical problems with the physical disk The virtual disk has lost redundancy Corrupted metadata in the virtual disk • Check if the physical disk in the virtual disk has failed. • If a physical disk was recently removed and replaced, check that it is correctly positioned in the backplane. Check the cable connections at the physical disk and at the motherboard. Perform a rescan. • One or more physical disks in the virtual disk have failed. Due to the failed physical disk or disks, the virtual disk is no longer maintaining redundant (mirrored or parity) data. The failure of an additional physical disk results in lost data. • Replace the physical disk or disks. Rebuild the physical disk using Storage Management. See the applicable Storage Management screen, located on the Dell Support website at support.dell.com/manuals. 1 Delete the virtual disk that has the failed metadata. 2 Assign the physical disk as a hot spare to rebuild a redundant virtual disk. 3 To create a non-redundant virtual disk, delete and rebuilt the data on a virtual disk, and restore the data from a backup storage source.

72 Troubleshooting Table 7-11. Cannot Assign a Dedicated Hot Spare to a Virtual Disk Likely Causes to Check Corrective Actions

The RAID level does not allow a dedicated hot spare to be created The designated physical disk does not have sufficient capacity to be a dedicated hot spare The physical disk is already part of a virtual disk The physical disks are of different types Hot spares cannot be created for Volume or RAID 0 virtual disks. The capacity of the physical disk selected to be a dedicated hot spare must be equal to or larger than the capacity of the smallest physical disk in the virtual disk. For example, if the physical disk selected for a dedicated hot spare is 160 GB, and the physical disks in the virtual disk are 80 GB, 160 GB, and 500 GB, a dedicated hot spare can be assigned. That is because the physical disk selected for the dedicated hot spare is larger than the smallest (80 GB) physical disk in the virtual disk. A dedicated hot spare cannot be assigned to another virtual disk. The physical disk used as a dedicated spare must be the same type as the physical disks that are already part of the virtual disk. For example, if a virtual disk consists of SATA-II physical disks, the dedicated hot spare must be a SATA-II physical disk.

Table 7-12. Cannot Create a Global Hot Spare Likely Causes to Check Corrective Actions

There are no empty physical disks available or the physical disks have not been initialized Install additional physical disks and initialize them. If existing physical disks have a status of New they need to be initialized. WARNING: When a physical disk is initialized, all data on the physical disk is lost. NOTE: A physical disk with a Non-Raid status can be initialized, if desired, but it is no longer Non-Raid (initialization adds PERC S100 adapter/PERC S300 adapter configuration information to the physical disk).
