Overview 1 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 commandline interface (CLI). The GUI is wizard-driven and includes features for novice and advanced users. The CLI is fully featured and scriptable.
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. Storage Management generates alerts 2131 and 2132 when it detects unsupported firmware or drivers on a controller. For information on alert messages, see the Server Administrator Messages Reference Guide.

To implement disk and volume management, you must use the native disk and volume management utilities provided by your operating system.
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.

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.
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.
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.
same data always. Either side of the mirror can act as the operational side. A mirrored RAID disk group is comparable in performance to a RAID 5 disk group in read operations but faster in write operations. • 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.
view volumes and use drives from these volumes for creation of new virtual disks or Online Capacity Expansion (OCE) of existing virtual disks, provided free space is available. Storage Management allows Rename and Delete operations on such volumes. Choosing RAID Levels And Concatenation You can use RAID or concatenation to control data storage on multiple disks. Each RAID level or concatenation has different performance and data protection characteristics.
• Concatenates n disks as one large virtual disk with a capacity of n disks. • 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. • 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 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 Performance Write Performance Transactional reads: Very good writeback cache Rebuild Performance Minimum Disks Suggested Required Uses intensive transactional uses. RAID 10 Excellent Very Good Fair Good 2N x X Data intensive environments (large records). RAID 50 Good Very Good Fair Fair N + 2 (N = at least 4) Medium sized transactional or data intensive uses. RAID 6 Excellent Sequential reads: good.
Quick Access To Storage Status And Tasks 4 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.
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.

NOTE: The Global Rescan task updates the configuration changes in the Information/Configuration page. To update the tree view, click the server name which is displayed above the tree view. To globally rescan: 1. In the Server Administrator window, under the System tree, expand Storage. 2.
Property Definition Name Displays the name of the controller. For more detailed information on a controller, click its name on the controller name. Slot ID Displays the slot to which the controller is attached. Storage Management displays Slot Not Applicable for controllers for which it is unable to display the slot ID and Embedded for embedded controllers.
Property Definition Alarm State Displays whether the alarm on the controller is enabled or disabled. Cluster Mode Indicates whether the controller is part of a cluster configuration. SCSI Initiator ID Displays the SCSI ID of a SCSI controller. The default value is 7. You can change the default value in the BIOS. When controllers in a cluster configuration display duplicate SCSI Initiator IDs, refer to SCSI documentation.
Controllers 8 This chapter provides information about the supported controllers and controller features in Storage Management. Related Links RAID Controller Technology: SCSI, SATA, ATA, And SAS Which Controllers Do I Have? Non-RAID Controller Description What Is A Controller? Most operating systems do not read and write data directly from the disks, but instead send read and write instructions to a controller.
• SAS 6/iR controller family • PERC S100, S110, and S300 controllers • PERC H200, H700, and H800 controllers • PERC H310 Adapter, PERC H310 Mini Monolithic, PERC H310 Mini Blades, PERC H710 Adapter, PERC H710 Mini Blades, PERC H710 Mini Monolithic, PERC H710P Adapter, PERC H710P Mini Blades, PERC H710P Mini Monolithic, and PERC H810 Adapter controllers RAID Controller Features Different controllers have different features.
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. Related Links Changing The Virtual Disk Policy 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.
NOTE: Write-through is the default write policy setting when cluster mode is enabled. • Write Cache Enabled Protected — The controller writes data to the write cache before writing data to the physical disk. Because it takes less time to write data to the write cache than it does to a disk, enabling write cache can improve system performance. After data is written to the write cache, the system is free to continue with other operations.
The background initialization process helps the controller identify and correct problems that may occur with the redundant data later. In this regard, the background initialization process is similar to a check consistency. The background initialization should be allowed to run to completion. If canceled, the background initialization automatically restarts within 0 to 5 minutes. Some processes such as read and write operations are possible while the background initialization is running.
Table 14. Firmware/Driver Properties Property Definition Firmware Version Displays the version of the firmware that is installed on the controller. NOTE: Storage Management displays Not Applicable on some controllers for which the firmware version cannot be obtained. Minimum Required Firmware Version Displays the minimum firmware version that is required by Storage Management. This property is displayed only if the controller firmware does not meet the minimum requirement.
Controllers Properties And Tasks Use the controllers properties and tasks window to view information about the controller and execute controller tasks. NOTE: The firmware and drivers listed in the Server Administrator Readme 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. The controller properties can vary depending on the model of the controller.
Property Definition Minimum Required Driver Version Displays the minimum driver version that is required by Storage Management. This property is displayed only if the controller driver does not meet the minimum requirement. Number of Connectors Displays the number of connectors on the controller. Each connector can be attached to physical disks or an enclosure. Depending on the controller type, the connector can be either a SCSI channel or a SAS port.

On a system running Microsoft Windows, the log file is exported to the windows or winnt directory. On a system running Linux, the log file is exported to the /var/log directory. Depending on the controller, the log file name is afa_.log or lsi_.log, where is the month and date. NOTE: In the VMware ESXi environment, only one log file is created (lsiexport.log). If the file exists, exporting the log file overwrites the existing log file.
If you do not want to import or clear the foreign configurations, or in case of loss of the associated passphrase of the corresponding Encryption Key Identifier, execute the Instant Encrypt Erase task for the physical disks. CAUTION: Executing the Instant Encrypt Erase task erases all data on the physical disk. Some conditions, such as an unsupported RAID level or an incomplete disk group, can prevent the import or recovery of foreign virtual disks.
Property Definition • • • Import and Export — The virtual disks available for import exceed the number of virtual disks available for export. Incompatible physical disks — Configuration on the physical disks is not recognized by the RAID firmware. Orphan drive — A physical disk in the foreign configuration has configuration information that matches another physical disk that is already a part of an array (either a foreign or a native array).
that was originally configured as a RAID 5 using three physical disks, then the RAID 5 virtual disk is in a Failed state and cannot be imported. In addition to virtual disks, a foreign configuration may consist of a physical disk that was assigned as a hot spare on one controller and then moved to another controller. The Import Foreign Configuration task imports the new physical disk as a hot spare.
After moving a physical disk from one controller to another, you may find that the physical disk contains all or some portion of a virtual disk (foreign configuration). You can identify whether a previously used physical disk contains a foreign configuration (virtual disk) by checking the physical disk state. If the physical disk state is Foreign, then the physical disk contains all or some portion of a virtual disk.
Property Definition For more information, see Storage Component Severity. Name Displays the name of the physical disk. The name is comprised of the connector number followed by the disk number. State Displays the current state of the physical disk. After Import State Displays the after-import state of the physical disk. The physical disk can be imported in any of the following states: • • • • • Online — The physical disk is part of the imported virtual disk and functions normally.
Property Definition Media Displays the media type of the physical disk. The possible values are: • • • Used RAID Disk Space HDD — Hard Disk Drive. A HDD is a non-volatile storage device which stores digitally-encoded data on rapidly rotating platters with magnetic surfaces. SSD — Solid-State Drive. An SSD is a data storage device that uses solidstate memory to store persistent data. Unknown — Storage Management is unable to determine the media type of the physical disk.
Property Definition • Rebuild Product ID Displays the serial number of the drive which can be used as a unique number to identify the disk. Encryption Capable Displays whether the physical disk is a Self Encryption Disk (SED). The possible values are Yes and No. Encrypted Displays whether the physical disk is encrypted to the controller. The possible values are Yes and No. For a non-SED the value is N/A. Part Number Displays the unique Bill Of Materials assignment number for a physical disk.
The Set Check Consistency Rate task changes the amount of system resources dedicated to the check the consistency rate. The check consistency rate, configurable between 0% and 100%, represents the percentage of the system resources dedicated for running the check consistency task. At 0%, the check consistency has the lowest priority for the controller, takes maximum time to complete, and has least impact to system performance.

CAUTION: You may not be able to use Storage Management to manage the preserved cache in some cases. As an example, consider you have a RAID 1 level with two disks — D1 and D2. If you now remove D2, the virtual disk is degraded and the data in the controller cache is written to D1. So, D1 has the latest data. Now, if you re-insert D2 and pull out D1, the virtual disk is still degraded and does not have the latest data.
CAUTION: It is important to understand that if you lose the Passphrase, you cannot recover it. If you move the physical disks associated with the lost Passphrase to another controller or if the controller fails or is replaced, you cannot access data from that disk. NOTE: If Encryption Key Identifier or Passphrase contain special characters such as & , " , <, and >, in the file, they are written as & , ", < and > respectively.

Connectors 10 A controller contains one or more connectors (channels or ports) to which you can attach disks. You can externally access a connector by attaching an enclosure (for external disks) to the system or internally access by attaching to the backplane (for internal disks) of a system. You can view the connectors on the controller by expanding the controller object in the tree view. NOTE: For PCIe-SSD, connectors are referred to as PCIe-SSD extenders.
disks that can be used for different RAID levels, see Number Of Physical Disks Per Virtual Disk. For information on controller-specific implementations of the RAID levels, see Controller - Supported RAID Levels. Creating A Physical Disk For Channel Redundant Virtual Disks On PERC Controllers The following sections describe creating a channel-redundant virtual disk using RAID 10 or RAID 50 on PERC controllers.
Property Definition — Critical/Failure/Error For more information, see Storage Component Severity. A Warning or Critical severity may indicate that the connector is unable to communicate with attached devices such as an enclosure. Check the status of attached devices. For more information, see Cables Attached Correctly and Isolate Hardware Problems. Name Displays the connector number. State Displays the status of the connector. Possible values are: • • • Ready — The connector is functioning normally.

Tape Drive Properties Property Definition ID Displays the ID of the tape drive. Name Displays the name of the tape drive. Bus Protocol Displays the bus protocol type of the tape drive.
RAID Controller Batteries 12 Some RAID controllers have batteries. If the controller has a battery, Storage Management displays the battery under the controller object in the tree view. If there is a power outage, the controller battery preserves data that is in the volatile cache memory (SRAM) but not yet written to disk. The battery is designed to provide a minimum backup of 24 hours. When a RAID controller is first installed in a server, the battery may need charging.
Property Definition • • Auto — Storage Management performs an automatic learn cycle based on the set time. Warn — The learn cycle is past the default 90 days. When the battery is in Warn mode, the state of the controller is displayed as degraded. NOTE: Warn is available only on SAS controllers with firmware version 6.1 and later. Next Learn Time Displays the number of days and hours left before the controller firmware initiates the next learn cycle.
While the learn cycle is in progress, the battery may not be able to maintain the cache during a power loss. If the controller is using Write-Back Cache policy, then the controller changes to Write-Through Cache policy until the learn cycle completes. The write-through cache policy writes the data directly to the disk and reduces the risk of data loss in the cache during a power outage.
4. Select Delay Learn Cycle from the Available Tasks drop-down menu. 5. Click Execute.
Physical Disks Or Physical Devices 13 Physical disks or physical devices reside within an enclosure or are attached to the controller. On a RAID controller, physical disks or devices are used to create virtual disks. Related Links Physical Disk Tasks Guidelines To Replace A Physical Disk Or Physical Device A replacement disk may not be the same model as the physical disks or devices in the storage enclosure.

Degraded — The physical disk or device has encountered a failure and is operating in a Degraded state. Failed — The physical disk or device has encountered a failure and is no longer functioning.
Property Definition • Non-RAID — Non-RAID disks are exposed to the operating system unlike unconfigured disks and enables usage of disk in direct passthrough mode. Maximum number of non-RAID disks that can be supported on H310 controller are 64. You can perform the following tasks on the Non-RAID disks: • • • Identified as locate option. Execute a blink or unblink operation. Select the disk as a bootable device.
Property Definition Encryption Capable Displays whether the physical disk or device is a Self-Encryption Disk (SED). The possible values are Yes and No. Encrypted Displays whether the physical disk or device is encrypted to the controller. The possible values are Yes and No. For a non-SED the value is N/A. Bus Protocol Displays the technology that the physical disk or device is using. Possible values are: • • • Media SCSI SAS SATA Displays the media type of the physical disk or device.
Property Definition Negotiated Speed Displays the speed of data transfer that the disk negotiated while spinning up and upon initial communication with the controller. This speed is dependent on the speed of the disk, the capable speed of the controller, the current speed of the controller on that connector, and the speed of the Enclosure Management Module (EMM ) on the enclosure. Capable Speed Displays the highest possible speed that the device can transfer data.
• Convert To RAID Capable Disk • Convert To Non-RAID Disk Blinking And Unblinking A Physical Disk Does my controller support this feature? See Supported Features. The Blink task allows you to find a disk within an enclosure by blinking one of the light-emitting diodes (LEDs) on the disk. You can use this task to locate a failed disk. On most controllers, the Blink task automatically cancels after a short duration such as 30–60 seconds.
NOTE: This procedure is not available for physical disks or devices that have been assigned as a hot spare or physical disk or devices that are part of a virtual disk.

Protecting Your Virtual Disk With A Hot Spare 16 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.
Dedicated Hot Spare Protection Policy Table 35. 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.
• 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, and S300 controllers. Considerations For Enclosure Affinity • Enclosure affinity settings for dedicated hot spare are applicable only on PERC 5 and PERC 6 family of controllers.
Dedicated Hot Spare Considerations The following considerations apply to dedicated hot spares: • Considerations for RAID 10, RAID 50, and RAID 60 — If you have created a RAID 10 or RAID 50 virtual disk that does not fully consume its member physical disks, then you cannot assign a dedicated hot spare to the RAID 10 or RAID 50 virtual disk. Storage Management does not allow you to create RAID 10 and RAID 50 virtual disks from partial physical disks.
• Immediately replace any physical disk that has failed or been removed. This ensures that a healthy disk resides in a slot that the controller firmware assumes is a hot spare.
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.
3. Click a storage controller component. 4. Under Available Tasks, select Manage CacheCade. 5. Click Execute. The CacheCade(s) page is displayed. Related Links CacheCade Using Solid-State Drives CacheCade Properties The CacheCade(s) page displays a table of properties for each CacheCade.

Related Links Common Troubleshooting Procedures Virtual Disk Troubleshooting Specific Problem Situations And Solutions PCIe SSD Troubleshooting Fluid Cache For DAS Common Troubleshooting Procedures This section describes commands and procedures that can be used in troubleshooting.
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. NOTE: You can verify which firmware and drivers are installed by selecting the Storage object in the tree view and clicking Information/Configuration.
Replacing The Disk To replace the failed disk that is part of a redundant virtual disk: 1. Remove the failed disk. 2. Insert a new disk. Make sure that the new disk has equal or greater memory space than the one you are replacing. On some controllers, you may not be able to use the additional space by inserting a disk that has a higher memory space. A rebuild is automatically initiated because the virtual disk is redundant.
Setting The Physical Disk Online Or Offline Recovering From Removing The Wrong Physical Disk If the physical disk that you mistakenly removed is part of a redundant virtual disk that also has a hot spare, then the virtual disk rebuilds automatically either immediately or when a write request is made. After the rebuild has completed, the virtual disk no longer has a hot spare since data has been rebuilt onto the disk previously assigned as a hot spare. In this case, assign a new hot spare.
• The virtual disk includes failed or corrupt physical disks — This situation may generate alert 2083. For information on alert messages, see the Server Administrator Messages Reference Guide. • The rebuild rate setting is too low — If the rebuild rate setting is quite low and the system is processing a number of operations, then the rebuild may take an unusual amount of time to complete. • The rebuild is canceled — Another user can cancel a rebuild that you have initiated.
Virtual Disk Errors On Systems Running Linux On some versions of the Linux operating system, the virtual disk size is limited to 1TB. If you create a virtual disk that exceeds the 1TB limitation, your system may experience the following behavior: • I/O errors to the virtual disk or logical drive. • Inaccessible virtual disk or logical drive. • 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.
Physical Disk Is Offline Or Displays An Error Status A physical disk may display an error status if it has been damaged, is offline, or was a member of a virtual disk that has been deleted or initialized. The following actions may resolve the error condition: • If a user has changed the status to Offline, then return the disk to Online status by executing the Online disk task. • Rescan the controller. This action updates the status of storage objects attached to the controller.
Alerts 2146 Through 2150 Received While Performing I/O, Consistency Check, Format, Or Other Operation If you receive alerts 2146 through 2150 while performing an operation other than a rebuild, replace the damaged disk immediately to avoid data loss. Perform the following steps: 1. Back up the degraded virtual disk to a fresh (unused) tape drive. 2. Replace the damaged disk. 3. Perform a rebuild.
Storage Management May Delay Displaying Storage Devices After Reboot Storage Management requires time after a reboot to find and inventory all attached storage devices. You may experience a delay in storage controllers being displayed until this operation has completed.
