ICP RAID Console 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. Remove Hot Fix Drive This option allows you to remove a hot fix drive from an existing array drive. To access this function, from the Advanced Setup menu: • Select the Configure Array Drives option and press Enter to display the Select Array Drive screen. • Select an array drive and press Enter to display the Array Drive window. • Select the Remove Hot Fix Drive option and press Enter. After you choose the Remove Hot Fix Drive option, ICPCON displays a warning message to confirm the removal of the selected hot fix drive. Press to proceed with the removal, or press to cancel the operation. Hot Fix Pool Access To access this function, from the Advanced Setup menu: • Select the Configure Array Drives option and press Enter to display the Select Array Drive screen. • Select an array drive and press Enter to display the Array Drive window. • Select the Hot Fix Pool Access option and press Enter.

ICP RAID Console
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.
Remove Hot Fix Drive
This option allows you to remove a hot fix drive from an existing array drive.

to confirm the removal of the selected hot fix drive. Press <Y> to proceed with the
removal, or press <N> to cancel the operation.
