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.
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. 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.
NOTE: A logical connector is displayed for all PERC 10 and later family of hardware controllers, HBA controllers, and MX series controllers all the physical disks will be detected under this logical connector. However, the logical connector will not be displayed under PERC 9 and prior family of hardware controllers,12 Gbps HBA and PERC H840. NOTE: At times, the connector ID for SAS 12 Gbps HBA may not be displayed correctly on Storage Management.
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.

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.
The online Help is available as: ● Context-sensitive Help — Each Storage Management page has a icon. Click this icon to display the context-sensitive online Help that describes the contents of the displayed page. ● Table of Contents — The table of contents is available in the page that displays the information when you access the context-sensitive Help. Common Storage Tasks This section provides information on commonly performed storage tasks: ● Create and configure virtual disks (RAID configuration).
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 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 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.
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.
● Redundancy for protection of data. ● 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.
Table 1. RAID Level and Concatenation Performance Comparison (continued) RAID Level Data Availability Read Performance Write Performance Rebuild Performance Minimum Disks Required Suggested Uses data intensive 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.
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.
NOTE: You may not receive SMART alerts when the I/O of a controller is paused. Using Alarms To Detect Failures Certain storage components have alarms which when enabled, alert you when the component fails. Using Enclosure Temperature Probes Physical disk enclosures have temperature probes that warn you when the enclosure has exceeded an acceptable temperature range.
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.

NOTE: This task is not supported on PERC 10 controllers. 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.
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.
● Creating and deleting virtual disks on cluster-enabled controllers — There are particular considerations for creating or deleting a virtual disk from a cluster-enabled controller. ● 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.
physical disks). Since, the number of total stripes and spans is limited, the number of physical disks that can be used is also limited. The limitations on stripes and spans affect the possibilities for concatenation and RAID levels as follows: ● Maximum number of spans affects RAID 10, RAID 50, and RAID 60. ● Maximum number of stripes affects RAID 0, RAID 5, RAID 50, RAID 6, and RAID 60. ● Number of physical disks in a mirror is always 2. This property affects RAID 1 and RAID 10.
In order to implement RAID functions, you must create a virtual disk. A virtual disk refers to 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 seen by the operating system as a single disk. Before creating a virtual disk, you should be familiar with the information in Considerations Before Creating Virtual Disks.
Table 34.
Managing Virtual Disk Bad Block Management Virtual disk bad blocks are bad blocks on one or more member physical disks. The read operation on the virtual disks having bad blocks may fail. Storage Management generates a critical alert (2387) to notify you of the bad blocks on the virtual disk. Virtual disk bad blocks are discovered when the controller performs any operation that requires scanning the disk.
Table 35. Sample Scenarios For Virtual Disk Bad Blocks (continued) RAID Level Virtual Disk State Scenario Result (LBA) to another physical location. The problem is resolved. Recommendations For Clearing Bad Blocks Storage Management allows you to clear the bad block warnings. To clear bad blocks, the following procedure is recommended: 1. Perform a backup of the virtual disk with the Verify option selected. One of the following scenarios may occur: ● Backup operation fails on one or more files.
Table 36. Virtual Disk Properties (continued) Property Definition ● Degraded — A physical disk in a redundant virtual disk is not online. ● Resynching — A consistency check is being performed on the virtual disk. Performing a Cancelling A Check Consistency on a virtual disk while it is in Resynching state causes the virtual disk to be in a Failed Redundancy state. ● Resynching Paused — A consistency check has been paused on the virtual disk.
Table 36. Virtual Disk Properties (continued) Property Definition Media Displays the media type of the physical disks present in the virtual disk. The possible values are: ● HDD ● SSD ● Unknown — Storage Management is unable to determine the media type of the physical disk. NOTE: You cannot have a mix of HDD and SSD media on a virtual disk.

NOTE: For PERC H700 and PERC H800 controllers, you can assign a dedicated hot spare to RAID 10, RAID 50, and RAID 60. ● Considerations for Multiple Dedicated Hot Spares — From Storage Management version 3.1 onwards, you can assign more than one dedicated hot spare to a virtual disk. Considerations For Hot Spares On PERC S100, PERC S300, PERC S130 and later controllers For the PERC S100, PERC S300, PERC S130 and later controllers, a hot spare is assigned to a virtual disk.
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.
4. Create a new virtual disk. 5. Restore from backup. 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 virtual disk is nonredundant — For example, a RAID 0 virtual disk cannot be rebuilt because RAID 0 does not provide data redundancy. ● There is no hot spare assigned to the virtual disk — As long as the virtual disk is redundant, to rebuild it: ○ Remove the failed physical disk and replace it. A rebuild automatically starts on the new disk. ○ Assign a hot spare to the virtual disk and then perform a rebuild.
● Virtual disk or logical drive size is smaller than expected. If you have created a virtual disk that exceeds the 1TB limitation, you must: 1. Back up your data. 2. Delete the virtual disk. 3. Create one or more virtual disks that are smaller than 1TB. 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.
● 2148 ● 2149 ● 2150 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.
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. This problem resolves when the Windows operating system recovers from hibernation.
Physical Disks Are Displayed Under The Connector Object Instead Of The Enclosure Object Storage Management surveys the status of physical disks at frequent intervals. When the physical disk is located in an enclosure, the data reported by the SCSI Enclosure Processor (SEP) is used to determine the status of the physical disk. When the SEP is not functioning, Storage Management can survey the status of the physical disk, but cannot identify the physical disk as being located in the enclosure.
19 Frequently Asked Questions This section provides frequently asked questions that address situations commonly experienced in a storage environment.
