When a member drive in the logical drive failed, the controller will
first check whether there is a Local Spare Drive assigned to this
logical drive. If yes, it will automatically start to rebuild.
If there is no Local Spare Drive available, the controller will search
for a Global Spare Drive. If there is a Global Spare Drive, it will
automatically rebuild the logical drive.
If neither a Local Spare Drive nor a Global Spare Drive is available,
and the “Periodic Auto-Detect Failure Drive Swap Check Time” is
“Disabled,” the controller will not try to rebuild unless the user
applies a forced manual rebuild.
When the “Periodic Auto-Detect Failure Drive Swap Check Time” is
enabled (i.e., a check time interval has been selected), the controller
will detect whether or not the failed drive has been swapped (by
checking the failed drive’s channel/ID). Once the failed drive has
been swapped, the rebuild will begin immediately.
