Managing Spare Drives
When a physical drive in a disk array fails and a spare drive of adequate capacity
is available, the disk array will begin to rebuild automatically using the spare
drive. See “Critical & Offline Disk Arrays” on page 276.
Spare drive management includes the following functions:
• Viewing a List of Spare Drives (page 117)
• Locating a Spare Drive (page 117)
