2.5 Hot-plug Drive Replacement
The RAID controller supports the ability of performing a hot-swap
drive replacement without powering down the system. A disk can
be disconnected, removed, or replaced with a different disk without
taking the system off-line. The RAID rebuilding will be processed
automatically in the background. When a disk is hot swap, the
RAID controller may no longer be fault tolerant. Fault tolerance will
be lost until the hot swap drive is subsequently replaced and the
rebuild operation is completed.
2.5.1 Recognizing a Drive Failure
A drive failure can be identified in one of the following ways:
1). An error status message lists failed drives in the event log.
2). A fault LED illuminates on the front of RAID subsystem if
failed
drives are inside.
