Adaptec CI/O Management Software User's Guide 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: s 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 10-6
