Restoring RAID Subsystem Configuration
1.9.1 Setting Target IDs for the Controller
Set the SCSI IDs to be used for your storage sets. Dual controllers need preferred ID’s
restored also. These ID’s were recorded in Section 1.4
“
SHOW THIS_CONTROLLER
”
.
Use up to four ID’s for the controller while avoiding the ID of the host adapter (normally
ID7). For this example, use SCSI IDs 0, 1, 2, and 3. Enter the command:
HSZ> set this_controller id=(0,1,2,3)
The CLI will indicate that a restart of the controller is necessary for the change to take
effect. Either press and release the green Reset switch or enter the command:
HSZ> restart this_controller
For dual-redundant configurations enter:
HSZ> set failover copy=this_controller
When the CLI finishes initializing, set the preferred IDs. For example, if the preferred
IDs are 0 and 1, enter the command:
HSZ> set this_controller preferred_id=(0,1)
1.9.2 Add Disks to Configuration
HSZ> run config
1.9.3 Recreate Storagesets
NOTE
Use the CLI “add” command to recreate the
Storagesets in the following command examples but
DO NOT initialize the storageset using the “init”
command or you will lose all data on the storageset.
Recreate the storagesets recorded earlier.
HSZ> add stripeset
container-name.....
HSZ> add mirrorset
container-name disk-device.....
HSZ> add raidset
container-name.....
Where container-name is the name of the appropriate type of storageset container and
disk- device is a list of devices that are part of the storageset.
