Replacing an Active Array Member
Follow these instructions if you want to remove an array member of
a RAID 1, RAID 0/1, or RAID 5 array that has not actually failed and
replace it with another disk drive. You may want to do this if the
drive has generated a S.M.A.R.T. predictive failure alert.
1
Perform a Down operation on the array member you want to
replace (see Downing the Drive on page 7-13).
If a spare disk was already available, the Reconstruct operation
begins automatically when you down the array member.
2
If the array enclosure supports hot swapping, remove the
member marked as down.
3
Insert the replacement drive and issue the rescan command.
4
If the array member is an enclosure that does not support hot
swapping, pause I/O. (Skip steps 4 though 7 if the array
enclosure supports hot swapping.)
5
Remove the disk drive and allow I/O to resume.
6
Pause I/O again.
7
Insert the replacement drive and allow I/O to resume.
8
When a pool spare with a capacity as large as the smallest
member of the critical array or a spare dedicated to the critical
array is created, the reconstruct will start automatically.
Responding to an Off-line Array
You can tell that an array is in off-line status if OFFLINE appears in
the Array Status field in Adaptec CI/O Management Software or if
the Array icon in the Storage Configuration window looks like this:
. There are several reasons for an array going off-line, as
described below:
A member of a RAID 0 has failed, a second disk in a Critical
RAID 5 array has failed, or both disks of a mirrored pair in a
RAID 1 or RAID 0/1 array have failed.
If this happens, delete the off-line array, create a new array, and
restore the data from your most recent backup. You cannot
