Drive Failures
Drive failures are indicated by flags, which differ depending on
whether they refer to an array or a drive in an array. Failure
conditions are indicated as follows:

The failure of a RAID drive causes the audible alarm to sound. The
alarm stops automatically (after the initial system scan) when you
start Storage Manager or SMOR.
