4.1.7.7 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 determines the drive is experiencing
a fault and executes 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 ExaSAN RAID system, that drive will be locked if
insert it to another RAID system.
