Getting Started 2 Server Administrator Storage Management is designed for system administrators who implement hardware RAID solutions and understand corporate and small business storage environments. Storage Management enables you to configure the storage components attached to your system. These components include RAID and non-RAID controllers and the channels, ports, enclosures, and disks attached to them.
On A System Running Linux And Any Remote System To start a Server Administrator session on a Linux or any remote system, click the Server Administrator icon on your desktop and log in using an account with Administrator privileges. Or, open a web browser and type one of the following in the address field and press : https://:1311 where is the assigned name for the managed system and 1311 is the default port.
Health On the Properties page, click Health to view the status information for the storage components. Related Concepts Storage Health Information/Configuration On the Properties page, click Information/Configuration to view the property information for a storage object. The Information/Configuration subtabs also have options for executing storage tasks or launching wizards. Using The Storage Management Command-Line Interface Storage Management has a fully featured command-line interface (CLI).
– Protecting Your Virtual Disk With A Hot Spare — This topic provides information on hot spares and controller-specific information. • Perform a Check Consistency — The Maintaining The Integrity Of Redundant Virtual Disks task verifies the accuracy of the redundant data on a virtual disk. • Reconfigure a Virtual Disk — To expand the capacity of a virtual disk you can add physical disks to the virtual disk. You can also change the RAID levels.
Understanding RAID concepts 3 Storage Management uses the Redundant Array of Independent Disks (RAID) technology to provide Storage Management capability. Understanding Storage Management requires an understanding of RAID concepts, as well as some familiarity with how the RAID controllers and operating system view disk space on your system.
RAID concepts RAID uses particular techniques for writing data to disks. These techniques enable RAID to provide data redundancy or better performance. These techniques include: • • • • • • • Mirroring — Duplicating data from one physical disk to another physical disk. Mirroring provides data redundancy by maintaining two copies of the same data on different physical disks. If one of the disks in the mirror fails, the system can continue to operate using the unaffected disk.
• • • • volumes, availability or fault-tolerance is achieved by maintaining redundant data. Redundant data includes mirrors (duplicate data) and parity information (reconstructing data using an algorithm). Performance — Read and write performance can be increased or decreased depending on the RAID level you choose. Some RAID levels may be more appropriate for particular applications.
When a physical disk in a concatenated or spanned volume fails, the entire volume becomes unavailable. Because the data is not redundant, it cannot be restored by rebuilding from a mirrored disk or parity information. Restoring from a backup is the only option. Because concatenated volumes do not use disk space to maintain redundant data, they are more costefficient than volumes that use mirrors or parity information.
RAID 0 characteristics: • Groups n disks as one large virtual disk with a capacity of (smallest disk size) *n disks. • Data is stored to the disks alternately. • No redundant data is stored. When a disk fails, the large virtual disk fails with no means of rebuilding the data. • Better read and write performance. RAID level 1 (mirroring) RAID 1 is the simplest form of maintaining redundant data. In RAID 1, data is mirrored or duplicated on one or more physical disks.
RAID 1 characteristics: • Groups n + n disks as one virtual disk with the capacity of n disks. The controllers currently supported by Storage Management allow the selection of two disks when creating a RAID 1. Because these disks are mirrored, the total storage capacity is equal to one disk. • Data is replicated on both the disks. • When a disk fails, the virtual disk still works. The data is read from the mirror of the failed disk. • Better read performance, but slightly slower write performance.
RAID 5 characteristics: • Groups n disks as one large virtual disk with a capacity of (n-1) disks. • Redundant information (parity) is alternately stored on all disks. • When a disk fails, the virtual disk still works, but it is operating in a degraded state. The data is reconstructed from the surviving disks. • Better read performance, but slower write performance. • Redundancy for protection of data.
RAID 6 characteristics: • Groups n disks as one large virtual disk with a capacity of (n-2) disks. • Redundant information (parity) is alternately stored on all disks. • The virtual disk remains functional with up to two disk failures. The data is reconstructed from the surviving disks. • Better read performance, but slower write performance. • Increased redundancy for protection of data. • Two disks per span are required for parity. RAID 6 is more expensive in terms of disk space.
RAID 50 characteristics: • Groups n*s disks as one large virtual disk with a capacity of s*(n-1) disks, where s is the number of spans and n is the number of disks within each span. • Redundant information (parity) is alternately stored on all disks of each RAID 5 span. • Better read performance, but slower write performance. • Requires as much parity information as standard RAID 5. • Data is striped across all spans. RAID 50 is more expensive in terms of disk space.
RAID 60 characteristics: • Groups n*s disks as one large virtual disk with a capacity of s*(n-2) disks, where s is the number of spans and n is the number of disks within each span. • Redundant information (parity) is alternately stored on all disks of each RAID 6 span. • Better read performance, but slower write performance. • Increased redundancy provides greater data protection than a RAID 50. • Requires proportionally as much parity information as RAID 6.
RAID 10 characteristics: • Groups n disks as one large virtual disk with a capacity of (n/2) disks, where n is an even integer. • Mirror images of the data are striped across sets of physical disks. This level provides redundancy through mirroring. • When a disk fails, the virtual disk still works. The data is read from the surviving mirrored disk. • Improved read performance and write performance. • Redundancy for protection of data.
Comparing RAID Level And Concatenation Performance The following table compares the performance characteristics associated with the more common RAID levels. This table provides general guidelines for choosing a RAID level. Evaluate your specific environment requirements before choosing a RAID level. NOTE: The following table does not show all supported RAID levels in Storage Management. For information on all supported RAID levels in Storage Management, see Choosing RAID Levels And Concatenation. Table 1.
RAID Level Data Availability Read Performanc e Write Performanc e Rebuild Performanc e Minimum Disks Required Suggested Uses critical information. RAID 5 Good Sequential reads: good. Transactiona l reads: Very good Fair, unless using writeback cache Fair N + 1 (N = at least two disks) Databases and other read intensive transactional uses. RAID 10 Excellent Very Good Fair Good 2N x X Data intensive environment s (large records).
No-RAID In Storage Management, a virtual disk of unknown metadata is considered a No-RAID volume. Storage Management does not support this type of virtual disks. These must either be deleted or the physical disk must be removed. Storage Management allows Delete and Rename operation on No-RAID volumes.
4 Quick Access To Storage Status And Tasks This section describes various methods to determine the status or health of the storage components on your system and how to quickly launch the available controller tasks.
Hot Spare Protection Policy The Set Hot Spare Protection Policy task allows you to set or modify the number of hot spares to be assigned to the virtual disks. After you set the number of assigned hot spares, any deviation from the protection policy threshold triggers an alert based on the severity level you set.
The State and Progress properties display the current activity of a component. For example, an offline physical disk displays the Offline status while the Progress property displays how close to completion an operation (such as a rebuild) is.
Using Enclosure Temperature Probes Physical disk enclosures have temperature probes that warn you when the enclosure has exceeded an acceptable temperature range. Related Concepts Setting The Temperature Probe Values Rescanning To Update Storage Configuration Changes The Rescan task scans the storage device attached to the connectors on the controller (channels or ports) to verify the currently connected devices or to recognize devices that have been added to or removed from the connectors.
PCI Express Solid-State Device Support 5 This section provides an overview of the Storage Management device management support for Peripheral Component Interconnect Express (PCIe) Solid-State Drive (SSD) and its associated devices like the backplane and extender card. In Storage Management, PCIe SSD appears under Storage in the tree view. Storage Management reports the PCIe SSD devices and its various properties.

This task is supported on H310 and H330 controllers. NOTE: This task is not supported on PERC hardware controllers running in HBA mode. Convert To Non-RAID Disk This task converts a disk to a Non-RAID disk. After converting a disk to non- RAID, the disk is exposed to the operating system unlike unconfigured good disks and it enables usage of disk in direct pass-through mode. This task is supported on H310 and H330 controllers.
Virtual Disks 14 A virtual disk refers to a storage created by a RAID controller from one or more physical disks. Although a virtual disk may be created from several physical disks, it is viewed by the operating system as a single disk. Depending on the RAID level used, the virtual disk may retain redundant data if there is a disk failure or have particular performance attributes. NOTE: Virtual disks can only be created on a RAID controller.
Virtual Disk Considerations For Controllers In addition to the considerations described in this section, you should also be aware of the controller limitations described in Number of Physical Disks per Virtual Disk for the following controllers: • PERC 6/E and PERC 6/I • PERC H310 Adapter, PERC H310 Mini Monolithic, and PERC H310 Mini Blades • PERC H700, PERC H710 Adapter, PERC H710 Mini Blades, PERC H710 Mini Monolithic • PERC H800, PERC H810 Adapter • PERC H330 Adapter, PERC H330 Mini Monolithic,
• Implementing channel redundancy — A virtual disk is channel-redundant when it maintains redundant data on more than one channel. If one of the channels fails, data is not lost because redundant data resides on another channel. NOTE: For more information about channel redundancy, see Channel Redundancy And Thermal Shutdown. • Rebuilding data — An failed physical disk that is used by both redundant and nonredundant virtual disks cannot be rebuilt.
Related Concepts Number Of Physical Disks Per Virtual Disk Virtual Disk Considerations On Systems Running Linux On some versions of the Linux operating system, the virtual disk size is limited to 1TB. Before creating a virtual disk that is larger than 1TB, you should make sure that your operating system supports this virtual disk size. The support provided by your operating system depends on the version of the operating system and any updates or modifications that you have implemented.

RAID Level Virtual Disk State Scenario Result Addressing (LBA) to another physical location. The problem is resolved. RAID 5 Degraded One bad block on a physical disk. The controller cannot regenerate data from the peer disks because one drive is missing. This results in a virtual disk bad block. RAID 5 Ready One bad block on two physical disks at the same location. The controller cannot regenerate data from the peer disks. This results in a virtual disk bad block.
• Backup operation completes without error. This indicates that there are no bad blocks on the written portion of your virtual disk. If you still receive bad block warnings, the bad blocks are in a non-data area. Proceed to step 2. 2. Run Patrol Read and check the system event log to ensure that no new bad blocks are found. If bad blocks still exist, proceed to step 3. If not, the condition is cleared without the need for step 3. 3.

This selection groups two disks as one virtual disk with the capacity of a single disk. The data is replicated on both disks. When a disk fails, the virtual disk continues to function.
• Select RAID 50 to implement striping across more than one span of physical disks. RAID 50 groups n*s disks as one large virtual disk with a capacity of s*(n-1) disks, where s is the number of spans and n is the number of disks within each span. • Select RAID 60 to implement striping across more than one RAID 6 span. RAID 60 groups n*s disks as one large virtual disk with a capacity of s*(n-2) disks, where s is the number of spans and n is the number of disks within each span.
• Physical disk 0:0 • Physical disk 0:1 Each RAID level has specific requirements for the number of disks that must be selected. RAID 10, RAID 50, and RAID 60 also have requirements for the number of disks that must be included in each stripe or span. If the controller is a SAS controller with firmware versions 6.1 and later and you selected RAID 10, RAID 50, and RAID 60, the user interface displays the following: • All Disks — Enables you to select all the physical disks in all the enclosures.
The virtual disk size must be within the minimum and maximum values displayed near the Size field. In some cases, the virtual disk is slightly larger than the size you specify. The Create Virtual Disk Wizard adjusts the size of the virtual disk to avoid rendering a portion of the physical disk space unusable. NOTE: If a physical disk is receiving a SMART alert, it cannot be used in a virtual disk.
The Create Virtual Disk Advanced Wizard (Step 3 of 3) - page displays a check box next to each physical disk that is suitable as a dedicated hot spare. Select a Physical Disk check box if you want to assign a dedicated hot spare The Physical Disk check box is not available if the controller does not have a physical disk that is a suitable hot spare for the virtual disk you are creating. For example, the available physical disks may be too small to protect the virtual disk.
NOTE: If you want to reconfigure a virtual disk with an additional physical disk, the physical disk must be of supported bus protocol, media type, sector size, T10 Protection Information capability, and encryption capability. NOTE: You may want to review Virtual Disk Considerations For Controllers. This section contains considerations that also apply to reconfiguring a virtual disk on these controllers.

NOTE: On some controllers, performing a Rescan while a reconfiguration is in progress causes the virtual disk configuration and the physical disk state to display incorrectly. For example, changes to the RAID level of the virtual disk may not be displayed and the state of physical disks that were added to the virtual disk may display as Ready instead of Online.
Formatting Or Initializing A Disk To format or initialize a disk: 1. Review the virtual disk that is destroyed by the Format or Initialize and make sure that vital data is not lost. Click Blink at the bottom of the page to blink the physical disks included in the virtual disk. 2.
• There are particular considerations for deleting a virtual disk from a cluster-enabled controller. • It is recommended that you reboot the system after deleting the virtual disk. Rebooting the system ensures that the operating system recognizes the disk configuration correctly. • If you delete a virtual disk and immediately create a new virtual disk with all the same characteristics as the one that was deleted, the controller recognizes the data as if the first virtual disk were never deleted.

16 Protecting Your Virtual Disk With A Hot Spare When you create a virtual disk using a RAID controller, it enables the system to continue functioning even during a disk failure. This feature can be enabled by assigning a hot spare to the virtual disk. When a disk fails, the redundant data is rebuilt onto the hot spare without interrupting system operations.
Assigning And Unassigning Global Hot Spare Dedicated Hot Spare Protection Policy Table 31. Hot Spare Properties Property Definition RAID Level Indicates the RAID level(s) for which you want to configure the hot spare protection policy. Minimum Number of Disks Indicates the minimum number of physical disks to be assigned as dedicated hot spares for the selected RAID level(s). Severity Level Displays the severity level you want to assign to the generated alert, if this policy is violated.
• For SAS/iR and PERC H200 family of controllers, you can assign only two global hot spares. • If the status of the virtual disk is displayed as Degraded or Failed because of the hot spare protection policy violation, then assign the required number of hot spares (as defined in the protection policies) for the status to be displayed as normal. • Hot Spare Protection Policy is not applicable to PERC S100, S110, S130, and S300 controllers.
After you have assigned a global hot spare, any new virtual disks created on the controller are not protected by the hot spare in either of the following circumstances: • The controller is a SAS controller and the disk size is larger than the global hot spare. In this case, you can unassign the global hot spare after creating a new virtual disk and then assign a new and larger hot spare to cover all redundant virtual disks on the controller.
When a physical disk fails in a redundant virtual disk, the failed disk is rebuilt onto the hot spare. In this case, the controller firmware reassigns the slot containing the failed disk as the hot spare. In this circumstance, a disk not previously assigned as a global hot spare becomes a hot spare through failure or removal.
CacheCade Using Solid-State Drives 17 CacheCade is used to improve random read performance of the solid-state drive (SSD) based virtual disks. A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. SSDs significantly increase the I/O performance (IOPS) and/or write speed in Mbps from a storage device. With storage controllers, you can create a CacheCade using SSDs. The CacheCade is then used for better performance of the storage I/O operations.
The CacheCade(s) page is displayed. 1. In the Server Administrator window, under the System tree, expand Storage. 2. Click a storage controller. For example: PERC H710P Adapter. 3. Click a storage controller component. 4. Under Available Tasks, select Manage CacheCade. 5. Click Execute. The CacheCade(s) page is displayed. Related Concepts CacheCade Using Solid-State Drives CacheCade Properties The CacheCade(s) page displays a table of properties for each CacheCade.
CacheCade size = capacity of the smallest SSD * the number of SSDs 4. From the available free disks that are displayed, select the SSDs that you would like to include in the CacheCade. The selected disks are displayed in the Physical Disks Selected section. 5. Click Finish. NOTE: The procedure of selecting physical disks while creating a CacheCade is similar to the selection of disks while creating a virtual disk.
Troubleshooting 18 This section contains troubleshooting procedures for common situations as well as for specific problems. Related Concepts Common Troubleshooting Procedures Virtual Disk Troubleshooting Specific Problem Situations And Solutions PCIe SSD Troubleshooting Common Troubleshooting Procedures This section describes commands and procedures that can be used in troubleshooting.
System Requirements Make sure that the system meets all system requirements. In particular, verify that the correct levels of firmware and drivers are installed on the system. Related Concepts Drivers And Firmware Drivers And Firmware Storage Management is tested with the supported controller firmware and drivers. In order to function properly, the controller must have the minimum required version of the firmware and drivers installed. The most current versions can be obtained from the support site.
Replacing A Failed Disk That Is Part Of A Redundant Virtual Disk If the failed disk is part of a redundant virtual disk, then the disk failure will not result in data loss. You must replace the failed disk immediately, however, as additional disk failures can cause data loss. If the redundant virtual disk has a hot spare assigned to it, then the data from the failed disk is rebuilt onto the hot spare.
Using The Physical Disk Online Command On Select Controllers Does my controller support this feature? See Supported Features. If you do not have a suitable backup available, and if the failed disk is part of a virtual disk on a controller that supports the Online physical disk task, then you can attempt to retrieve data by selecting Online from the drop-down task menu of the failed disk. The online command attempts to force the failed disk back into an online state.
Virtual Disk Troubleshooting The following sections describe troubleshooting procedures for virtual disks: • Replacing A Failed Disk That Is Part Of A Redundant Virtual Disk • A Rebuild Does Not Work • A Rebuild Completes With Errors • Cannot Create A Virtual Disk • Virtual Disk Errors On Systems Running Linux • Problems Associated With Using The Same Physical Disks For Both Redundant And Non-Redundant Virtual Disks A Rebuild Does Not Work A rebuild does not work in the following situations: •
The rebuild may also report sense key errors. In this situation, take the following actions to restore the maximum data possible: 1. Back up the degraded virtual disk onto a fresh (unused) tape drive. • If the backup is successful — If the backup completes successfully, then the user data on the virtual disk has not been damaged. In this case, you can continue with step 2. • 2.
Problems Associated With Using The Same Physical Disks For Both Redundant And Non-Redundant Virtual Disks When creating virtual disks, you should avoid using the same physical disks for both redundant and nonredundant virtual disks. This applies to all controllers. Using the same physical disks for both redundant and nonredundant virtual disks can result in unexpected behavior including data loss.
Receive A Bad Block Alert With Replacement, Sense, Or Medium Error The following alerts or events are generated when a portion of a physical disk is damaged: • 2146 • 2147 • 2148 • 2149 • 2150 This damage is discovered when the controller performs an operation that requires scanning the disk.
Isolate Hardware Problems A Task Menu Option Is Not Displayed You may notice that the task menus do not always display the same task options. Some tasks are only valid for certain types of objects or at certain times. For example, a Check Consistency task can only be performed on a redundant virtual disk. Similarly, if a disk is already offline, the Offline task option is not displayed. There may be other reasons why a task cannot be run at a certain time.
