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 Logical Drives” on page 189.
Spare drive management includes the following functions:
• Viewing a List of Spare Drives (page 149)
• Creating a Spare Drive (page 150)
• Deleting Spare Drive (page 151)
• Making Spare Drive Settings (page 151)
• Running Spare Check (page 152)
