Common Replacement Information and Procedures

Replacing a Failed JBOD

DELETE UNIT DXXX
4. Delete the disk with the following command:
DELETE DISKXXXX
5. Quiesce the bus.
6. Replace the failed disk with a new disk that is the same size or larger.
7. Add a new disk to the controller configuration with one of the following
commands:
ADD DISK DISKXXXX
or
RUN CONFIG
8. Add a unit with the following command:
ADD UNIT DXXX DISKXXXX
9. Mount the disk to the operating system.
10. Restore the data from the backup.

Replacing a Storage Unit with Partitions

Storage containers that have partitions created on them present a unique maintenance
issue in that the partition may reside on one disk (JBOD) or across several disks (Raid
0, Raid 0+1, Raid 5). Failure of any partition may require the replacement (backup and
restore) of the data contained in all partitions on that device. This is particularly true of
a partitioned JBOD. Great care must be exercised when planning the use of partitions
for anything other than temporary data storage.
