4.1.2.8.7 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 replacing a damaged drive with a new one, the newly added drive might be locked.
Click Unlock to allow the array to rebuild the drive. You can check the rebuild progress in the
Main view.
Note
The time required for on-the-fly initialization, drive building, online
expansion and migration may vary according to the capacity of the
drive and the array.
