Re-create Enhanced Remote Mirroring Repository Logical Drive

This command creates a new Enhanced Remote Mirroring repository logical drive (also called a mirror repository logical drive) by using the parameters defined for a previous mirror repository logical drive. The underlying requirement is that you have previously created a mirror repository logical drive. When you use this command, you can define the mirror repository logical drive in one of three ways: user-defined disk drives, user-defined array, or user-defined number of disk drives for the mirror repository logical drive. 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.

Syntax (User-Defined Disk Drives)

recreate storageSubsystem mirrorRepository repositoryRAIDLevel=(1 | 3 | 5 | 6) repositoryDrives=(enclosureID1,slotID1 ... enclosureIDn,slotIDn) [enclosureLossProtect=(TRUE | FALSE)]

Syntax (User-Defined Array)

recreate storageSubsystem mirrorRepository repositoryArray=arrayName [freeCapacityArea=freeCapacityIndexNumber]

Syntax (User-Defined Number of Disk Drives)

recreate storageSubsystem mirrorRepository repositoryRAIDLevel=(1 | 3 | 5 | 6) repositoryDriveCount=numberOfDrives [driveType=(fibre | SATA | SAS | PATA)] [enclosureLossProtect=(TRUE | FALSE)]

Parameters
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 and slot ID 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 array where the mirror repository logical drive is located.
freeCapacityArea

The index number of the free space in an existing array that you want to use to re-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.
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.
Notes

If you enter a value for the storage space of the mirror repository logical drive that is too small, the controller firmware returns an error message, which states the amount of space that is needed for the mirror repository logical drive. The command does not try to change the mirror repository logical drive. You can re-enter the command by using the value from the error message for the storage space value of the mirror repository logical drive.

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 mirror repository logical drive 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 mirror repository logical drive having enclosure loss protection. If you set the enclosureLossProtect parameter to FALSE, the storage subsystem performs the operation even if it means that the mirror repository logical drive might not have enclosure loss protection.
