Unlock Drives
The RAID controller may lock abnormal drives in an array. You may unlock these drives and
rejoin them in an array. Drives may be locked with one of two conditions:
1. If a drive returns data too slowly, the controller will determine the drive is experiencing a
failure and execute Drive Drop. When you unlock the drive, it will be added directly to the
array if there has not been drive access during the locked period. Otherwise, the controller
will rebuild parity data on the drive when the drive is online.
Note
If "Drive Drop" occurs, it is recommended to use S.M.A.R.T. to check
the drive condition and replace it if necessary.
2. When a drive has been used by RAID system, that drive will be locked if insert it to another
RAID system.
Follow the steps below to select a drive to unlock.
1. Select the drive with the
