Selection of this option will allow you to create a Disk Array. Selection of this option allows you to view/change parameters associated with a specific Disk Array. This option allows the user to maintain the status of physical drives which are not yet configured into a Disk Array. Allows the user to view the status of all of the physical drives within the selected RAID device. Allows the user to remove a SPARE drive from the RAID device (status of the drive will transition from SPARE to NON-EXISTENT). Allows the user to add a SPARE drive to the RAID device (status of the drive will transition from NON-EXISTENT to SPARE), or to transition a HOT SPARE drive back to SPARE. This is the desired size of the newly created Disk Array in megabytes. The combination of the RAID level and number of drives you specify determines the total number of megabytes in the Disk Array. For example, a 5-drive RAID 5 Disk Array with 2000 MByte drives (unformatted drive size) has a Disk Array size of 8000 MBytes. (Four drives are used for data and one for parity in a RAID 5 Disk Array (4 X 2000 MByte = 8000 MByte)). This is the number of contiguous Kbytes which will be written to a single drive before switching to the next drive in the disk array. It provides the host with a method to tune data striping to the typical IO request size. The option to modify this parameter is allowed prior to first Disk Array creation only. Recovery options typically should only be invoked if an error log entry has been detected or your adapter has been replaced. These options will allow the user to synchronize the adapter configuration with the actual hardware configuration, and in the case of adapter replacement, synchronize with the drive resident configuration. This field allows the selection of spare drives which will become associated with the new Disk Array. A spare drive is a drive which exists within the RAID device but which is not yet configured into an existing Disk Array. Note that any drives which are specified to be part of this new Disk Array will be parity corrected when this panel is executed (except in the case of a RAID Level 0 device). The guidelines are as follows: RAID level 0 - Number of drives allowed = 1-16 RAID level 1 - Number of drives allowed = 2-16 RAID level 5 - Number of drives allowed = 3-16 Allows the user to transition a drive from SPARE to HOT SPARE. A HOT SPARE drive is used to automatically replace (and reconstruct) a FAILED drive in a redundant (RAID Level 1 or 5) Disk Array . This is the RAID Level of the Disk Array selected above. This can not be changed from this menu. A change in RAID Level will automatically cause a reformat of the drive(s). This is the current status of the selected Disk Array. This can not be changed from this menu. The possible values are: OPTIMAL - the Disk Array is operating normally. DEGRADED - A single drive has failed in a RAID 1 or 5 Disk Array, and the unit is now in degraded mode. Replace the failed drive as soon as possible. Check the drive statuses to determine which drive failed. The status will remain degraded until the new drive is reconstructed. DEAD - The Disk Array is not functioning. Any data which may have been on the array is lost. Check individual drive statuses. RECONSTRUCTING -The adapter is reconstructing drive data on the new drive. Allows the user to transition a drive from FAILED to NON-EXISTENT. Note that this is allowed only on drives which are not currently part of a Disk Array. This is the size in MBytes of the selected Disk Array. This can not be changed from this menu. This option allows the user to select a FAILED drive, which is part of a DEGRADED Disk Array, to reconstruct. Typically the user will replace the original FAILED drive with a new drive before attempting this procedure. This is the rate at which data reconstruction operations will occur. During this time, the Disk Array performs I/O system operation. A lower rate will improve overall system performance. WARNING:USE WITH CAUTION This option may be used to delete a Disk Array typically when you want to do the following: - Change the RAID level of an existing Disk Array - Change the drives in an existing Disk Array - Change the stripe size. Note that in this case all Disk Arrays must be deleted before the stripe size may be changed. Before deleting the Disk Array, you MUST backup all data in all logical volumes and filesystems on the Disk Array and remove the Disk Array from its volume group. Once the Disk Array is deleted, you can NOT access it - the data is lost. Use this option to check and/or repair array parity. Array parity is used in RAID Levels 1 and 5 Disk Arrays to enable data to be reconstructed if a single drive fails. Checking and repairing parity helps insure that you will be able to recover after a drive failure. You should check and repair parity after an abnormal system shutdown. Selection of this menu allows you to service and maintain your RAID Subsystem. Selection of this option allows you to configure a system defined RAID Adapter. When a device is defined, an instance of that particular device is recorded in the Customized Configuration Database. All of the device's attributes are known and recorded, but the device is not yet usable by the system. After the device is configured, it is said to be Available. This selection allows you to configure a system defined Disk Array. When a device is defined, an instance of that particular device is recorded in the Customized Configuration Database. All of the device's attributes are known and recorded, but the device is not yet usable by the system. After the device is configured, it is said to be Available. This option allows the user to synchronize the RAID configuration with the configuration currently stored on the majority of the physical drives. This would typically be done only in the case of a RAID Adapter replacement. Select the desired logical device from the list. This option allows the user to bring a FAILED drive, which is part of a DEGRADED Disk Array, back to the ONLINE state without performing data reconstruction. This is not recommended and should be done with caution. WARNING: This will destroy all data on the selected subsystem. This should be attempted ONLY when the user wants to clear the subsystem's configuration. All Disk Arrays will be destroyed. This option should be selected when the error log has indicated such. The user will be able to resolve any RAID configuration conflicts which were detected during a boot operation. RAID is a term that means 'Redundant Array of Independent Disks'. The RAID level indicates the way the array controller reads and writes data and parity of the drives. Valid RAID levels are 0,1 and 5. The guidelines are as follows: RAID level 0 - Number of drives allowed = 1-16 RAID level 1 - Number of drives allowed = 2-16 RAID level 5 - Number of drives allowed = 3-16 Entering this menu will allow you to create, service and maintain the Disk Array hdisks for your system. If a RAID configuration conflict is detected during a boot sequence, an error will be posted in the system error log. This option will allow you to view any drive state change and/or any unidentified drives within an existing Disk Array. Once you have viewed the changes, you may choose to accept them. Alternatively, you may modify the existing hardware to your needs and execute the 'Retry Current Configuration' option on the prior panel. Selection of this option will allow you to view/change the parameters associated with your RAID Adapter. This option allows the user to perform a configuration reset which will synchronize the configuration to the current hardware. The RAID Adapter selected on the prior screen. This option allows the user to initiate automatic parity repair. This should not be done unless a parity error has been detected by running this command with this option set to 'no'. If a parity error is detected the user may then elect to 1)correct the error by running this command with this option set to 'yes' (in which case the parity will be recalculated), or 2)restoring the data from the backup medium. This allows the user to utilize the battery backup option on the RAID device. If the disk is a physical volume, its unique physical volume identifier is displayed in this field. If the disk is not a physical volume, this field value will be none. This allows the user to utilize read ahead data caching. This may improve performance on subsequent read operations. The LIST option provides you with a list of hdisks upon which parity checks may be run. This option allows the user to either display the configuration conflicts (default) or synchronize with the configuration changes. Allows the user to customize the depth of the command queue utilized for this Disk Array. Increasing this value may improve performance. This is the channel number/SCSI ID of the drive you have chosen. This is the channel number/SCSI ID of the drive which will be reconstructed and become part of this Disk Array. The default is the same location as the drive which has failed. In this case, the failed drive will typically have been replaced. This option allows the user to mark a drive as FAILED in the case where the adapter does not automatically detect a failure. This option allows the user to disable the Consistency Check during Disk Array creation. This is NOT advised and could result in data loss. This option allows the user to the display the Vital Product Data (ie. Model and Serial Number) about a particular drive. This option allows the user to enable or disable the data scrubbing option on the configured SCSI disk Arrays. Data Scrubbing is only supported on the Ultra SCSI version of the PCI SCSI RAID adapter. This option allows the user to view the current status of the non volatile adapter write cache for the selected PCI SCSI RAID adapter. The RAID Array selected on the prior screen. This field allows the selection of spare drives which will become associated with the new Disk Array. A spare drive is a drive which exists within the RAID device but which is not yet configured into an existing Disk Array. Note that any drives which are specified to be part of this new Disk Array will be parity corrected when this panel is executed (except in the case of a RAID Level 0 device). The guidelines are as follows: RAID level 0 - Number of drives allowed = 1-16 RAID level 1 - Number of drives allowed = 2-16 RAID level 5 - Number of drives allowed = 3-16 RAID level 5 Enhanced - Number of drives allowed = 4-16 This field allows the selection of spare drives which will become associated with the new Disk Array.

This can not be changed from this menu. The possible values are: OPTIMAL - the Disk Array is operating normally. DEGRADED - A single drive has failed in a RAID 1 or 5 Disk Array, and the unit is now in degraded mode. Replace the failed drive as soon as possible. Check the drive statuses to determine which drive failed. The status will remain degraded until the new drive is reconstructed. COMPRESSED - A single drive has failed in a RAID 5 Enhanced Disk Array, and the unit is now in compresses mode. Replace the failed drive as soon as possible. Check the drive statuses to determine which drive failed. The status will remain compressed until the array is decompresses./n DEAD - The Disk Array is not functioning. Any data which may have been on the array is lost. Check individual drive statuses. RECONSTRUCTING -The adapter is reconstructing drive data on the new drive. COMPRESSING - The adapter is compressing the data onto the distributed hot spare in a RAID 5 Enhanced Disk Array. This occurs when a single drive fails. DECOMPRESSING - The adapter is decompressing the data from a RAID 5 Enhanced Disk Array with a COMPRESSED status. This occurs when a single failed drive is replaced with a new drive. Data is decompressed onto the new drive. Use this option to check and/or repair array parity. Array parity is used in RAID Levels 1, 5 and 5 Enhanced Disk Arrays to enable data to be reconstructed (or decompressed for RAID 5 Enhanced) if a single drive fails. Checking and repairing parity helps insure that you will be able to recover after a drive failure. You should check and repair parity after an abnormal system shutdown. RAID is a term that means 'Redundant Array of Independent Disks'. The RAID level indicates the way the array controller reads and writes data and parity of the drives. Valid RAID levels are 0, 1, 5 and 5 Enhanced. The guidelines are as follows: RAID level 0 - Number of drives allowed = 1-16 RAID level 1 - Number of drives allowed = 2-16 RAID level 5 - Number of drives allowed = 3-16 RAID level 5 Enhanced - Number of drives allowed = 4-16 RAID is a term that means 'Redundant Array of Independent Disks'.
