This command creates the mirror repository logical drive and activates the Enhanced Remote Mirroring premium feature. When you use this command, you can define the mirror repository logical drive in one of three ways:
If you choose to define a number of disk drives, the controller firmware chooses which disk drives to use for the mirror repository logical drive.
activate storageSubsystem feature=remoteMirror repositoryRAIDLevel=(1 | 3 | 5 | 6) repositoryDrives=(enclosureID1,slotID1 ... enclosureIDn,slotIDn) [enclosureLossProtect=(TRUE | FALSE)]
activate storageSubsystem feature=remoteMirror repositoryArray=arrayName [freeCapacityArea=freeCapacityIndexNumber]
activate storageSubsystem feature=remoteMirror repositoryRAIDLevel=(1 | 3 | 5 | 6) repositoryDriveCount=numberOfDrives [driveType=(fibre | SATA | SAS | PATA)] [enclosureLossProtect=(TRUE | FALSE)]
Parameter | Description |
---|---|
repositoryRAIDLevel |
The RAID level for the mirror repository logical drive. Valid values are 1, 3, 5, or 6. |
repositoryDrives |
The disk drives for the mirror repository logical drive. Specify the enclosure ID value and the slot ID value for each disk drive that you assign to the mirror repository logical drive. Enclosure ID values are 0 to 99. Slot ID values are 1 to 32. Enclose the enclosure ID values and the slot ID values in parentheses. |
repositoryArray |
The name of the mirror repository array where the mirror repository logical drive is located. (To determine the names of the arrays in your storage subsystem, run the show storageSubsystem profile command.) |
freeCapacityArea |
The index number of the free space in an existing array that you want to use to create the mirror repository logical drive. Free capacity is defined as the free capacity between existing logical drives in an array. For example, an array might have the following areas: logical drive 1, free capacity, logical drive 2, free capacity, logical drive 3, free capacity. To use the free capacity following logical drive 2, you would specify: freeCapacityArea= 2 Run the show array command to determine if a free capacity area exists. |
repositoryDriveCount |
The number of unassigned disk drives that you want to use for the mirror repository logical drive. |
driveType |
The type of disk drives that you want to use for the mirror repository logical drive. Valid disk drive types are fibre, SATA, SAS, or PATA. Use this parameter only when you use the repositoryDriveCount parameter. You must use this parameter only when you have more than one type of disk drive in your storage subsystem. |
enclosureLossProtect |
The setting to enforce enclosure loss protection when you create the mirror repository logical drive. To enforce enclosure loss protection, set this parameter to TRUE. The default value is FALSE. |
If the disk drives that you select for the repositoryDrives parameter are not compatible with other parameters (such as the repositoryRAIDLevel parameter), the script command returns an error, and Enhanced Remote Mirroring is not activated. The error returns the amount of space that is needed for the mirror repository logical drive. You can then re-enter the command, and specify the appropriate amount of space.
If you enter a value for the repository storage space that is too small for the mirror repository logical drives, the controller firmware returns an error message that provides the amount of space that is needed for the mirror repository logical drives. The command does not try to activate Enhanced Remote Mirroring. You can re-enter the command by using the value from the error message for the repository storage space value.
When you assign the disk drives, if you set the enclosureLossProtect parameter to TRUE and have selected more than one disk drive from any one enclosure, the storage subsystem returns an error. If you set the enclosureLossProtect parameter to FALSE, the storage subsystem performs operations, but the array that you create might not have enclosure loss protection.
When the controller firmware assigns the disk drives, if you set the enclosureLossProtect parameter to TRUE, the storage subsystem returns an error if the controller firmware cannot provide disk drives that result in the new array having enclosure loss protection. If you set the enclosureLossProtect parameter to FALSE, the storage subsystem performs the operation even if it means that the array might not have enclosure loss protection.
