A drive with any other status (such as DPY/Rebuild or DPY/Unprotected) does not have device
parity protection.
Examples:
v Suppose one drive has a status of DPY/Failed while all other drives have a status of
DPY/Unprotected. In this case, only the drive with the DPY/Failed status is protected. Servicing
the failed drive does not result in data loss. Removing any of the unprotected drives might result in
data loss.
v All drives have a status of DPY/Active or DPY/Degraded, therefore, all drives are protected. In
this case, exchanging any drive does not result in data loss.
Tip: For more information about the meaning of a status for any drive, use the Help key on the
display.

1. To rebuild a drive by using the AIX operating system, complete the following steps:
Notes:
v If a hot-spare drive is available when the drive was put in the failed state, the AIX operating
