To monitor the rebuild progress
(Figure 94)
, enter command
SHOW JOB * ALL_ATTRIBUTES
To show the storage pool information

, enter command SHOW POOL <id>
ALL_ATTRIBUTES . Once the rebuild is complete, the status of storage pool will return to
“NORMAL”.
4.4.2 Drive Replacement
Upon completion of a rebuild, the spare drive becomes a member of the storage pool, replacing the
failed drive. After you have replaced the failed drive with a new drive, the new drive is added to the
unassigned pool. It is recommended that you assign this new drive to the spare pool to “replace” the
spare drive that has been used.
4.4.3 Spare Not Available
When a drive is failed by the system and there is no spare drive available, you need to replace the
failed drive immediately. After you have replaced the failed drive with a new drive, you can initiate
a rebuild as described below:
1. Enter command SHOW UNASSIGNED_POOL * ALL to identify the new drive’s index name.
2. Enter command ASSIGN PHYSICAL_DISK <new-disk-id> TO_POOL <pool-id>
SET_SPARE where <new-disk-id> is the index name of the replacement drive and <pool-id> is
the OID of the storage pool that had the failed drive.
