1 Overview Server Administrator Storage Management provides enhanced features for configuring the locally attached RAID and non-RAID disk storage on a system. Storage Management enables you to perform controller and enclosure functions for all supported RAID and non-RAID controllers and enclosures from a single graphical user interface (GUI) or command-line interface (CLI). The GUI is wizard-driven and includes features for novice and advanced users. The CLI is fully featured and scriptable.
controllers. Later versions of the firmware and drivers are also supported. For the most recent driver and firmware requirements, contact your service provider. NOTE: To download the latest storport driver, see the Microsoft Knowledge Base article KB943545 at support.microsoft.com. If you install Storage Management without the minimum required firmware and drivers, Storage Management may not be able to display the controllers or perform other functions.
2 Getting Started 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.
Information Or 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). For more information on CLI, see the Server Administrator Command Line Interface User’s Guide.
3 Understanding RAID concepts 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.
• Striping — Disk striping writes data across all physical disks in a virtual disk. Each stripe consists of consecutive virtual disk data addresses that are mapped in fixed-size units to each physical disk in the virtual disk using a sequential pattern. For example, if the virtual disk includes five physical disks, the stripe writes data to physical disks one through five without repeating any of the physical disks. The amount of space consumed by a stripe is the same on each physical disk.
The following topics provide specific information on how each RAID level or concatenation store data as well as their performance and protection characteristics: • Concatenation • RAID Level 0 (Striping) • RAID Level 1 (Mirroring) • RAID Level 5 (Striping With Distributed Parity) • RAID Level 6 (Striping With Additional Distributed Parity) • RAID Level 50 (Striping Over RAID 5 Sets) • RAID Level 60 (Striping Over RAID 6 Sets) • RAID Level 10 (Striping Over Mirror Sets) • Comparing RAID Leve
• Data fills up the first disk before it is written to the second disk. • No redundant data is stored. When a disk fails, the large virtual disk fails. • No performance gain. • No redundancy. RAID level 0 - striping RAID 0 uses data striping, which is writing data in equal-sized segments across the physical disks. RAID 0 does not provide data redundancy. RAID 0 characteristics: • Groups n disks as one large virtual disk with a capacity of (smallest disk size) *n 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 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.
RAID Level Data Availability Read Performance Write Performance Rebuild Performance Minimum Disks Required Suggested Uses RAID 1 Excellent Very Good Good Good 2N (N = 1) Small databases, database logs, and critical information. RAID 5 Good Sequential reads: good. Transactional reads: Very good Fair, unless using writeback cache Fair N + 1 (N = at least Databases and two disks) other read intensive transactional uses.
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.
Table 2. Component Severity Severity Component Status Normal/OK — The component is working as expected. Warning/Non-critical — A probe or other monitoring device has detected a reading for the component that is above or below the acceptable level. The component may still be functioning, but it could fail. The component may also be functioning in an impaired state. Data loss is possible. Critical/Failure/Error/Fatal — The component has either failed or failure is imminent.
Using Alarms To Detect Failures Certain storage components have alarms which when enabled, alert you when the component fails. Time Delay In Displaying Configuration Changes When you change the storage configuration, Storage Management quickly generates SNMP traps in response to the configuration changes. The Storage Management, Management Information Base (MIB) is also updated to reflect storage configuration changes.
5 PCI Express Solid-State Device Support 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.
Table 3. PCIe SSD Subsystem Properties Properties Description ID Displays the subsystem ID assigned to the PCIe SSD subsystem by Storage Management. Storage Management numbers the controllers and PCIe SSD subsystems attached to the system starting with zero. This number is the same as the PCIe SSD subsystem ID number reported by the omreportcommand. For information on Command Line Interface, see the Server Administrator Command Line Interface User's Guide.

7 Controllers This chapter provides information about the supported controllers and controller features in Storage Management.
SAS RAID Controllers The following RAID controllers use Serial Attached SCSI (SAS) technology. • PERC S140 • PERC H730P MX • PERC H745P MX RAID Controller Features Different controllers have different features. If you have more than one controller attached to your system, you may notice that the tasks displayed on the Information/Configuration page of the controller are different for each controller.
RAID Controller Read, Write, Cache, And Disk Cache Policy When creating a virtual disk, you can specify the read, write, and cache policies for the virtual disk. The following subsection describes these policies. Read Policy Does my controller support this feature? See Supported Features. The read policies indicate whether the controller should read sequential sectors of the virtual disk when seeking data. • Read Ahead — The controller reads sequential sectors of the virtual disk when seeking data.
NOTE: Storage Management does not allow you to select the Write Cache Enabled Protected policy for controllers that do not have a battery. This restriction protects a controller without a battery from the data loss that may occur in the event of a power failure. When using the Create Virtual Disk Advanced Wizard on a controller without a battery, the wizard either displays Write Cache Disabled as the only available option or the wizard does not display any option for write policy.
NOTE: The default setting for Disk Cache Policy for virtual disks based on SATA drives is Enabled, and for virtual disks based on SAS drives is Disabled. NOTE: For SAS 6i/R and PERC H200 family of controllers, the Disk Cache Policy setting is available only after creating the virtual disk.
NOTE: The firmware and drivers listed in the Server Administrator Release Notes refer to the minimum supported version for these controllers. Later versions of the firmware and drivers are also supported. For most recent driver and firmware requirements, contact your service provider. Table 8. Firmware/Driver Properties Property Definition Firmware Version Displays the version of the firmware that is installed on the controller.

Convert To Non-RAID Disk This task converts a disk to a Non-RAID disk.
15 Virtual Disks 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.
Considerations Before Creating Virtual Disks Different controllers have particular characteristics in the way they implement virtual disks. These characteristics may include use of disk space, limitations on the number of virtual disks per controller, and so on. It can be helpful to understand these characteristics before creating virtual disks on the controller.
• Reconfiguring virtual disks — The Reconfigure task is not available when you have more than one virtual disk using the same set of physical disks. You can, however, reconfigure a virtual disk that is the only virtual disk residing on a set of physical disks. • Virtual disk names not stored on controller — The names of the virtual disks that you create are not stored on the controller.
Number Of Virtual Disks Per Controller There are limitations on the number of virtual disks that can be created on the controller. For information about the maximum number of virtual disks supported by a controller, see the virtual disk specifications for the controller in Supported Features. Calculation For Maximum Virtual Disk Size The Create Virtual Disk Express Wizard displays the minimum and maximum values for the virtual disk size.
• The Create Virtual Disk Advanced Wizard allows you to specify the read, write, and cache policy for the virtual disk. You can also select the physical disks and the controller connector to be used. You need a good knowledge of RAID levels and hardware to use the advanced wizard. Reconfiguring Or Migrating Virtual Disks Does my controller support this feature? See Supported Features.

• I/O • Patrol Read Recovering a physical disk bad block depends on the RAID level and state of the virtual disk. If a virtual disk is redundant, the controller can recover a bad block on a physical disk. If a virtual disk is not redundant, then the physical disk bad block results in a virtual disk bad block. Table 26. Sample Scenarios For Virtual Disk Bad Blocks RAID Level Virtual Disk State Scenario Result RAID 0 Degraded One bad block on a physical disk.
• 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.
Property Definition • • • • RAID 1, RAID 10 or RAID 1-concatenated virtual disk suffers a physical disk failure. In addition, there are other conditions related to disk failures and the firmware that can cause a virtual disk to display a Failed Redundancy state. When a virtual disk is in Failed Redundancy state, performing a Check Consistency may return the virtual disk to a Ready state. Background Initialization — A background initialization is being performed on the virtual disk.
Property Definition Cache Policy Displays the cache policy that the controller is using for the selected virtual disk. See RAID Controller Read, Write, Cache, and Disk Cache Policy. Stripe Size Displays the stripe size of the virtual disk. Disk Cache Policy Displays whether the disk cache policy of the physical disks that is part of the virtual disk is enabled or disabled. See RAID Controller Read, Write, Cache, and Disk Cache Policy.
The Reconfigure task enables you to change the virtual disks properties. For example, you can use this task to add physical disks or change the RAID level. Format, Initialize, Slow, And Fast Initialize Does my controller support this feature? See Supported Features. The Format, Initialize, Slow Initialize, or Fast Initialize task enables you to erase the files and remove the file systems on a virtual disk. Some controllers require that you initialize a virtual disk before it can be used.
Cancelling A Check Consistency Does my controller support this feature? See Supported Features. The Cancel Check Consistency task stops a check consistency operation while it is in progress. Pausing A Check Consistency Does my controller support this feature? See Supported Features. The Pause Check Consistency task pauses a check consistency while it is in progress. NOTE: The Pause Check Consistency task updates the virtual disk State property to Resynching Paused immediately.
NOTE: If you cancel the rebuild of a physical disk that is assigned as a hot spare, reinitiate the rebuild on the same physical disk in order to restore the data. Canceling the rebuild of a physical disk and then assigning another physical disk as a hot spare does not cause the newly assigned hot spare to rebuild the data. Reinitiate the rebuild on the physical disk that was the original hot spare. Changing The Virtual Disk Policy Does my controller support this feature? See Supported Features.
To create a virtual disk using the Create Virtual Disk Express Wizard: 1 In the Server Administrator window, expand System > Storage. 2 Click Connector 0 (RAID). The Virtual Disk(s) on Controller page is displayed. 3 Click Go to the Create Virtual Disk Wizard. The Create Virtual Disk Wizard (Step 1) page is displayed. 4 Select the Express Wizard option and the RAID level from the drop-down list.
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. 3 Click Finish to complete the virtual disk creation. For PERC H700 and PERC H800 controllers, if any of the drives you selected is in the spun down state, the following message is displayed: The below listed physical drive(s) are in the Spun Down state.
• Select RAID 1 for mirroring disks. 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. This feature provides data redundancy and good read performance, but slightly slower write performance. The system must have at least two physical disks to use RAID 1. • Select RAID 5 for striping with distributed parity.
• SSD For more information on Bus Protocol and Media Type, see Virtual Disk Properties And Tasks. 10 Click Continue. The Create Virtual Disk Advanced Wizard (Step 2 of 3) — page is displayed with the connectors and physical disks available.
Let us consider that the controller has three enclosures with six physical disks each (total number of available disks = 3 x 6 =18 disks). If you select four disks per span, the controller creates four spans (18 disks/4 disks per span = 4 spans). The last two disks of the last enclosure are not part of RAID 10. • Select the number of disks to create a single spanned virtual disk list box — Enables you to create a single span virtual disk with 22 or 26 physical drives for PERC controllers.
NOTE: If you click Span Edit, Intelligent Mirroring that has already been applied becomes invalid. 5 Click Finish to complete the virtual disk creation. The virtual disk is displayed in the Virtual Disk(s) on Controller page. For PERC H700 and PERC H800 controllers, if any of the drives you selected is in the spun down state, the following message is displayed: The below listed physical drive(s) are in the spun down state.
3 Select the Virtual Disks object. 4 Select Reconfigure from the Available Tasks drop-down box. 5 Click Execute. Virtual Disk Task - Reconfigure Step 2 of 3 Does my controller support this feature? See Supported Features. The virtual disk reconfigure Step 2 page enables you to select the RAID level and size for the reconfigured virtual disk. The Expand Capacity option appears only for PERC H730P MX and PERC H745P MX controllers with firmware version 7.1 or later.
3 Click Continue to go to the next page or Exit Wizard if you want to cancel. To Reconfigure A Virtual Disk Expand Virtual Disk Capacity - Step 2 of 3 NOTE: For RAID 10 partial virtual disks, there are only two methods to increase the disk size or capacity: 1 • Expanding the capacity by increasing the percentage value. • Adding disks into the original RAID 10 virtual disk. Enter the percentage of the free disk size available by which you want to expand the virtual disk capacity.
The Slow Initialize task initializes one physical disk at a time. Each physical disk displays the Clear state while being initialized. While the physical disk is in the Clear state, the Cancel Clear physical disk task is available. Performing a Cancel Clear task on the physical disk causes the Slow Initialize task to be canceled for the entire virtual disk and all member physical disks.
• 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. In this situation, if you don't want the old data after recreating a new virtual disk, reinitialize the virtual disk. To Locate Delete In Storage Management 1 In the Server Administrator window, under the system tree, expand Storage to display the controller objects.
Changing The Read, Write, Or Disk Cache Policy Of A Virtual Disk 1 Select the new policy from the Read Policy, Write Policy, and Disk Cache Policy drop-down menus. 2 Click Apply Changes. To exit without changing the virtual disk policy, click Go Back To Virtual Disk Page. To Locate Change Policy In Storage Management 1 In the Server Administrator window, under the system tree, expand Storage to display the controller objects. 2 Expand a Controller object. 3 Select the Virtual Disks object.
Use the Unmirror task to separate mirrored data and restore one half of the mirror to free space. Unmirroring a RAID 1 or RAID 1concatenated virtual disk results in a single, nonredundant concatenated virtual disk. Unmirroring a RAID 10 virtual disk results in a single, nonredundant RAID 0 (striped) virtual disk. Data is not lost during this operation. NOTE: On systems running Linux operating systems, an Unmirror cannot be performed on a mounted virtual disk. To Unmirror Click Unmirror.
Unassigning A Dedicated Hot Spare 1 Select the disk in the Disks currently configured as dedicated hot spare table to unassign it. On some controllers, more than one disk can be selected. Clicking the disk removes the disk from the Disks currently configured as dedicated hot spare table and returns it to the Connector (channel or port) table. 2 Click Apply Changes when ready.
NOTE: For PERC H330, H730, H730P, H730P MX, H740P, H745P MX and H840 controllers, if any of the drives you selected is in the spun down state, the following message is displayed: The below listed physical drive(s) are in the spun down state. Executing this task on these drive(s) takes additional time, because the drive(s) need to spun up. The message displays the ID(s) of the spun down drive(s).
16 Moving Physical And Virtual Disks From One System To Another This section describes how to move physical and virtual disks from one system to another. Topics: • Required Conditions • Migrating SAS Virtual Disks To Another System Required Conditions SAS Controllers Virtual disks can only be migrated to a controller that is using the same technology. For example, virtual disks on a SAS controller must be migrated to a SAS controller.
17 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.
Property Definition NOTE: The status of the virtual disk is determined by the severity level you specify for this policy.

NOTE: You can verify which firmware and drivers are installed by selecting the Storage object in the tree view and clicking Information/Configuration. You can also check the Alert Log for alerts relating to unsupported firmware and driver versions. It is also recommended to obtain and apply the latest server system BIOS on a periodic basis to benefit from the most recent improvements. For more information on server system BIOS, see the system documentation.
Replacing A Failed Physical Disk That Is Part Of A Non-Redundant Virtual Disk If the failed physical disk is part of a nonredundant virtual disk (such as RAID 0), then the failure of a single physical disk causes the entire virtual disk to fail. To proceed, you need to verify when a backup was taken, and if there is any new data that has been written to the virtual disk since that time. If you have backed up recently and there is no new data on the disks that would be missed, you can restore from backup.
Resolving Microsoft Windows Upgrade Problems If you upgrade the Microsoft Windows operating system on a server, you may find that Storage Management no longer functions after the upgrade. The installation process installs files and updates registry entries on the server that are specific to the operating system. Changing the operating system can disable Storage Management. To avoid this problem, you should uninstall Storage Management before upgrading.
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.
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.
This damage is discovered when the controller performs an operation that requires scanning the disk. Examples of operations that may result in these alerts are as follows: • Consistency check • Rebuild • Virtual disk format • I/O If you receive alerts 2146 through 2150 as the result of performing a rebuild or while the virtual disk is in a degraded state, then data cannot be recovered from the damaged disk without restoring from the backup.
A Corrupt Disk Or Drive Message Suggests Running Autocheck During A Reboot You can ignore the message and perform autocheck. The reboot completes after autocheck is completed. Depending on the size of your system, it may take about 10 minutes. Erroneous Status And Error Messages After A Windows Hibernation Activating the Windows hibernation feature may cause Storage Management to display erroneous status information and error messages.
