Expanding or Extending the Capacity
of an Array

General steps for expanding the capacity of an array include:

1. Review. Refer to “Adding Storage Capacity” in Appendix E for

information on expanding the storage capacity of an existing Smart
Array 3200 Controller array.

2. Back up data. Although data loss is not anticipated during a normal

capacity expansion, it is a good idea to back up all data in the array you
will be expanding or extending. This backup may also be used to return
to the original configuration, if necessary.

3. Add drives. If you are using a server or storage system that does not

support hot-pluggable drives, you will need to power-down the server or
storage system to add new drives. If you are using a server or storage
system that does support hot-pluggable drives, do not power-down the
system or take it off line. Simply plug the new drives into vacant bays.

4. Configure drive array. Refer to “Capacity Expansion” in Chapter 5 for

instructions on using the Compaq Array Configuration Utility to
reconfigure your drive array and make use of the added capacity.
