Viewing Mirror Repository Logical Drive Properties

Related Topics

Use the Mirror Repository Logical Drive - Properties dialog to view basic information about a mirror repository logical drive . When you activate the Remote Mirroring premium feature, you specify the placement of the logical drives. You can either use existing free capacity or you can create an array for the logical drives from unconfigured capacity and specify the RAID level. You can choose RAID level 1, 3, or 5 for the mirror repository logical drives.

There are two mirror repository logical drives created for Remote Mirroring. Each logical drive stores mirroring information for one of the controllers in the storage subsystem; however, they are both owned by one of the controllers. The capacity is set at 4 MB for each logical drive. The segment size is set at 32KB (or 64 blocks). The controller determines the modification priority. The segment size and modification priority for a logical drive cannot be changed.

Note: To delete the mirror repository logical drives, use the Storage Subsystem >> Remote Mirroring >> Deactivate pull-down menu option. Deactivating the Remote Mirroring feature automatically removes the mirror repository logical drives for the storage subsystem.
