Expanding or Extending the Capacity of an Array

General steps for expanding the capacity of an array include:

1.Review. Refer to “Adding Storage Capacit y” 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 Expansio n” in Chapter 5 for instructions on using the Compaq Array Configuration Utility to reconfigure your drive array and make use of the added capacity.
