Changing RAID Controller Module Ownership You can change which RAID controller module owns a virtual disk by using the set virtualDisk command. The following syntax is the general form of the command: set (allVirtualDisks | virtualDisk [virtualDiskName] | virtualDisks [virtualDiskName1 ... virtualDiskNamen] | virtualDisk ) owner= (0 | 1) Initializing a Physical Disk CAUTION: When you initialize a physical disk, all data on the physical disk is lost. You must initialize a physical disk when you have moved physical disks that were previously part of a disk group from one storage array to another. If you do not move the entire set of physical disks, the disk group and virtual disk information on the physical disks that you move is incomplete. Each physical disk that you move contains only part of the information defined for the virtual disk and disk group. To be able to reuse the physical disks to create a new disk group and virtual disk, you must erase all old information from the physical disks by initializing the physical disk. When you initialize a physical disk, all old disk group and virtual disk information is erased, and the physical disk is returned to an unassigned state. Returning a physical disk to an unassigned state adds unconfigured capacity to a storage array. You can use this capacity to create additional disk groups and virtual disks. To initialize a physical disk, run the following command: start physicalDisk [enclosureID,slotID] initialize where, enclosureID and slotID are the identifiers for the physical disk. Reconstructing a Physical Disk If two or more physical disks in a disk group have failed, the virtual disk shows a status of Failed. All of the virtual disks in the disk group are no longer operating. To return the disk group to an Optimal status, you must replace the failed physical disks. After replacing the physical disks, reconstruct the data on physical disks. The reconstructed data is the data as it would appear on the failed physical disks. 102 Maintaining a Storage Array
