Full Initialization – Erases all sectors of the physical drives being added to
the logical drive.
•
None – No initialization. This choice is not recommended.
When you select full initialization, the process takes some time, depending on the
size of the physical drives selected for the logical drive. The Initialization tab
enables you to pause the initialization process so that more of FastTrak's
resources are available for other operations. When the other operations are
done, you can resume the initialization of your new logical drive.

Logical Drive Activation
This feature enables you to designate a hot plug-and-play logical drive. It will
become available in a future release of the FastTrak Controller card.
Logical Drive Critical / Offline
A fault-tolerant logical drive—RAID 1, 5 or 10—goes critical when a disk drive is
removed or fails. Due to the fault tolerance of the logical drive, the data is still
available and online. However, once the logical drive goes critical, it has lost its
fault tolerance and performance may be adversely affected.
If the fault was caused by a failed disk drive that was removed, the drive must be
replaced by another drive, either identical or larger, in order for the RAID system
to rebuild and restore optimal configuration.
A non-fault tolerant logical drive—RAID 0—goes offline when a disk drive is
removed or fails. Since the logical drive is not fault tolerant, the data stored in the
disk array is no longer accessible.
If one disk drive fails, all of the data on the logical drive is lost. You must replace
the failed drive. Then, if the logical drive had more than one disk drive, delete the
logical drive and re-create it. Restore the data from a backup source.
