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 nonRAID 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.
Supported Controllers 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 the most recent driver and firmware requirements, contact your service provider. This release of Storage Management supports the following controllers. Supported RAID Controllers Storage Management supports the following RAID controllers.
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.
where is the IP address for the managed system and 1311 is the default port. NOTE: Type https:// (not http://) in the address field to receive a valid response in your browser. User Privileges Server Administrator provides security through the User, Power User, and Administrator user groups. Each user group is assigned a different level of access to the Server Administrator features. The Administrator privileges are required to access all Storage Management features.
Common Storage Tasks This section provides information on commonly performed storage tasks: • Create and configure virtual disks (RAID configuration). For more information, see: • • • • Assign a hot spare to the virtual disk — When a virtual disk uses a RAID level, you can assign a hot spare (backup physical disk) to rebuild data if a physical disk in the virtual disk fails. • • • Create Virtual Disk Express Wizard — This topic provides information on using the Express Wizard to create a virtual disk.
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.
• • • • • Stripe size — The total disk space consumed by a stripe not including a parity disk. For example, consider a stripe that contains 64KB of disk space and has 16KB of data residing on each disk in the stripe. In this case, the stripe size is 64KB and the stripe element size is 16KB. Stripe element — A stripe element is the portion of a stripe that resides on a single physical disk. Stripe element size — The amount of disk space consumed by a stripe element.
• • • RAID Level 10 (Striping Over Mirror Sets) Comparing RAID Level And Concatenation Performance No-RAID Concatenation In Storage Management, concatenation refers to storing data on either one physical disk or on disk space that spans multiple physical disks. When spanning more than one disk, concatenation enables the operating system to view multiple physical disks as a single disk. Data stored on a single disk can be considered a simple volume.
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 is more expensive in terms of disk space since twice the number of disks are used than required to store the data without redundancy. RAID level 5 -striping with distributed parity RAID 5 provides data redundancy by using data striping in combination with parity information. Rather than dedicating a physical disk to parity, the parity information is striped across all physical disks in the disk group.
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. Two disks per span are required for parity.
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 Performance Write Performance Rebuild Performance Minimum Disks Required Suggested Uses RAID 6 Excellent Sequential reads: good. Transactional reads: Very good Fair, unless using writeback cache Poor N + 2 (N = at least two disks) Critical information. Databases and other read intensive transactional uses. RAID 60 Excellent Very Good Fair Poor X x (N + 2) (N = at least 2) Critical information. Medium sized transactional or data intensive 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.
Severity Component Status 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. The component requires immediate attention and may need to be replaced. Data loss may have occurred.
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. However, it may take up to five minutes to update the MIB with the most recent storage configuration.
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.
Properties Description — Normal/OK — Warning/Non-critical — Critical/Failure/Error Name Displays the name of the extender card. State Displays the status of the extender card. Possible values are: Ready — The extender card is functioning normally. Degraded — The extender card has encountered a failure and is operating in a degraded state.

Performing A Full Initialization On A Micron PCIe SSD Performing a Full Initialization on a Micron PCIe SSD overwrites all blocks and results in permanent loss of all data on the Micron PCIe SSD. During Full Initialization, the host is unable to access the Micron PCIe SSD. NOTE: If the system reboots or experiences a power loss during Full Initialization, the operation is canceled. You must reboot the system and restart the process.
CAUTION: Cryptographic Erase permanently erases all data present on the disk. Performing a Cryptographic Erase on an NVMe PCIe SSD overwrites all blocks and results in permanent loss of all data on the NVMe PCIe SSD. During Cryptographic Erase, the host is unable to access the NVMe PCIe SSD. NOTE: If the system reboots or experiences a power loss during Cryptographic Erase, the operation is canceled. You must reboot the system and restart the process.

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. Read ahead policy may improve system performance if the data is written to the sequential sectors of the virtual disk.
• Inconsistent — The disk cache policy is not uniform across all the physical disks in the virtual disk. For example, if a virtual disk contains three physical disks; the disk cache policy of the first physical disk is Enabled, the second physical disk is Disabled, and the third physical disk is Default. Then the disk cache policy state for the virtual disk is displayed as Inconsistent.
NOTE: For SAS 12 Gbps HBA and HBA 330 controller, the Available Reports that can be viewed are View Slot Occupancy Report and View Physical Disk Firmware Version Report. NOTE: At times, the connector ID for SAS 12 Gbps HBA may not be displayed correctly on Storage Management. This occurs because of a firmware limitation in the SAS 12 Gbps HBA. However, this connector ID discrepancy does not cause any functional limitation.

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.
• • Number Of Virtual Disks Per Controller Calculation For Maximum Virtual Disk Size You may also want to review the following sections: • • • • RAID Controller Read, Write, Cache, And Disk Cache Policy Understanding Hot spares Controller - Supported Stripe Sizes Time Delay In Displaying Configuration Changes NOTE: In addition to this document, review the hardware documentation that is provided with the controllers.
• • Rebuilding data — An failed physical disk that is used by both redundant and nonredundant virtual disks cannot be rebuilt. Rebuilding a failed physical disk in this situation requires deleting the nonredundant virtual disk. Disk group concept consideration for S110 — Disk grouping is a logical grouping of disks attached to a RAID controller on which one or more virtual disks are created, such that all virtual disks in the disk group use all of the physical disks in the disk group.
Calculation For Maximum Virtual Disk Size The Create Virtual Disk Express Wizard displays the minimum and maximum values for the virtual disk size. This section describes how the maximum possible size for the virtual disk is calculated based on the controller type. To identify the controller type, see RAID Controller Technology: SATA and SAS.
To reconfigure a virtual disk: 1. Review the information in Starting and Target RAID Levels for Virtual Disk Reconfiguration and Capacity Expansion. 2. Locate the controller on which the virtual disk resides in the tree view. Expand the controller object until the Virtual Disks object is displayed. 3. Select the Reconfigure task from the virtual disk’s Tasks drop-down list box and click Execute. 4. Complete the Reconfigure task using the Reconfigure wizard.
NOTE: When creating virtual disks using software RAID controllers, the information related to the physical disks linked to the virtual disk is enumerated or displayed on Storage Management after a short delay. This delay in displaying the information does not cause any functional limitation. If you are creating partial virtual disks, it is recommended that you provide Storage Management adequate time between each partial virtual disk creation process.
RAID Level Virtual Disk State Scenario Result 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.
Virtual Disk Properties The virtual disk properties can vary depending on the model of the controller. Table 35. Virtual Disk Properties Property Definition Status These icons represent the severity or health of the storage component. — Normal/OK — Warning/Non-critical — Critical/Failure/Error For more information, see Storage Component Severity. Name Displays the virtual disk name.

• Determining span calculation: • • Calculating the number of disks that can be utilized from the selected disks. • Maximizing the number of spans to increase the I/O performance Determining the mirror for the physical disks: The mirror is determined in a way that ensures maximum redundancy. The algorithm also tries to match a physical disk for its mirror, to a disk that is almost the same size. However, Intelligent Mirroring gives priority to size over redundancy.
• • • • Physical disk 0:1:0 Physical disk 0:2:0 Physical disk 0:3:0 Physical disk 0:4:0 Physical Disks Selected The Physical Disks Selected section of the page displays the disks you have chosen. In this example, two disks are selected. • • Physical disk 0:0:0 Physical disk 0:1:0 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.
NOTE: For a controller that has more than one channel, it may be possible to configure a virtual disk that is channelredundant. Depending on the RAID level you selected and the virtual disk size, this page displays the disks and connectors (channels or ports) available for configuring the virtual disk. NOTE: The Size field displays the default size of the virtual disk depending upon the RAID configuration you selected. You can specify a different size.
1. Select the physical disks that you want to include in the virtual disk. You can expand the capacity of the virtual disk by adding additional physical disks. On some controllers, you can also remove physical disks. The changes you make to the physical disk selection are displayed in the Selected Physical Disks table. NOTE: For a controller that has more than one channel, it may be possible to configure a virtual disk that is channelredundant.
• • • Select RAID 5 for striping with distributed parity — This selection groups n disks together as one large virtual disk with a total capacity of (n-1) disks. When a disk fails, the virtual disk continues to function. This feature provides better data redundancy and read performance, but slower write performance. The system must have at least three physical disks to use RAID 5.
Slow And Fast Initialize Considerations For Fast Initialize The Fast Initialize task initializes all physical disks included in the virtual disk. The Fast Initialize task updates the metadata on the physical disks so that all disk space is available for future write operations. The initialize task can be completed quickly because the existing information on the physical disks is not erased, although future write operations overwrite any information that remains on the physical disks.
Deleting A Virtual Disk Does my controller support this feature? See Supported Features. Deleting a virtual disk destroys all information including file systems and volumes residing on the virtual disk. NOTE: When deleting virtual disks, all assigned global hot spares may be automatically unassigned when the last virtual disk associated with the controller is deleted. When deleting the last virtual disk of a disk group, all assigned dedicated hot spares automatically become global hot spares.
Changing The Policy Of A Virtual Disk Does my controller support this feature? See Supported Features. Use the Change Policy task to change the read, write, or cache policy of a virtual disk. 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.

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.

Minimum Number of Disks Displays the minimum number of physical disks to be assigned as global hot spares for the controller. Severity Level Displays the severity level that you must assign to the generated alert, if the Global Hot Spare policy is violated.
18 Troubleshooting This section contains troubleshooting procedures for common situations as well as for specific problems. Topics: • • • • 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.
Isolate Hardware Problems If you receive a timeout alert related to a hardware device or if you otherwise suspect that a device attached to the system is experiencing a failure, then to confirm the problem: • • Verify that the cables are correctly connected. If the cables are correctly connected and you are still experiencing the problem, then disconnect the device cables and reboot the system. If the system reboots successfully, then one of the devices may be defective.
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.
• • • • • You are attempting to rebuild onto a hot spare that is too small — Different controllers have different size requirements for hot spares. The hot spare has been unassigned from the virtual disk — This occurs on some controllers if the hot spare is assigned to more than one virtual disk and is being used to rebuild a failed physical disk for another virtual disk. The virtual disk includes failed or corrupt physical disks — This situation may generate alert 2083.
4. Restore your data from backup. Irrespective of whether your Linux operating system limits the virtual disk size to 1TB, the virtual disk size depends on the version of the operating system and any updates or modifications that you have implemented. For more information on operating system, see your operating system documentation.
• • 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. If you receive alerts 2146 through 2150 under circumstances other than a rebuild, then data recovery may be possible. The following describes each of these situations.
Storage Management May Delay Before Updating Temperature Probe Status In order to display the enclosure temperature and temperature probe status, Storage Management polls the enclosure firmware at regular intervals to obtain temperature and status information. On some enclosures, there is a short delay before the enclosure firmware reports the current temperature and temperature probe status. This may cause a delay in displaying the correct temperature and temperature probe status.
PCIe SSD Troubleshooting The following sections describe troubleshooting procedures for PCIe SSD.
