manufacturers installation instructions.
Important Information for Rebuilding a Logical Drive
Review this section before you rebuild a logical drive.
If the logical drive is critical, you must rebuild the defunct hard
disk drive.
Data in a logical drive assigned or defined RAID level 0 is lost
during a rebuild. If you backed up your data before the drive
failed, you can restore the data to the new drive.
If a physical hard disk drive being rebuilt is part of a logical
drive defined as RAID level 0, 1 or 5, any RAID level 0 drive is
blocked to external access during the rebuild.
– If you initiated the rebuild through the Administration and
Monitoring program, you must unblock the RAID level 0
drive when the rebuild is complete.
– If you initiated the rebuild through the ServeRAID
configuration program and the rebuild was interrupted,
drives with RAID Level 0 can be unblocked by restarting
the server.
Only one rebuild operation can take place at a time.
The hard disk drive being rebuilt must be the same size or
larger than the failed drive.
If multiple hot-spare drives are available, the adapter searches
all bays on each Channel for a hot-spare drive of the
appropriate size; the first one found enters the Rebuild state.
An automatic hot-spare rebuild will take place if:
– The physical drive that failed is part of a RAID level 1 or 5
logical drive.
– A HSP or SHP drive is available the moment the drive fails
and no rebuild, synchronization, or RAID level change
operation is in progress.
Under the following circumstances, a Rebuild operation can be
completed quickly:
