Note:
To avoid wasting valuable storage capacity, it is recommended that all logical drives
forming an array drive have the same storage capacity.
When adding a hot fix drive, select a suitable drive, confirm your selection, and choose
whether to make the new hot fix drive be of type Private or Pool.
In the Event of a Drive Failure
The controller will substitute a failed logical drive with a hot fix drive only if the array
drive was in the
ready state before the failure. In other words, a hot fix drive can only be
activated if the corresponding array drive had a state of data redundancy at the moment of
failure.
The controller activates the fail operation mode. In this mode, the array drive remains
fully operational. The data located on the failed drive is generated by means of the
redundancy information stored on the other drives, without causing any decrease in
performance.
The controller integrates the hot fix drive into the array drive and begins reconstructing
the data and redundancy information. The array drive is now in the
rebuild mode.
No other hard disk may fail until all data has entirely been reconstructed on the hot fix
drive (because the system is operating without redundancy) without the array drive going
into error mode.
Note:
In some literature, hot fix drives are also referred to as hot spare drives. You can also add
or remove hot spare drives using ICP RAID Navigator.
