When you initialize disks, the RAIDCore configuration information is written to those disks. If the disks are new
and you have not used them before, you must initialize them before you can use the disks in RAIDCore arrays.
After a disk is initialized, it shows as a “Disk”
type in the
Disk List
.
To initialize disks:
1.
From the
Disk
menu, select
Initialize
.
Initialize Disk
is displayed.
2.
Select the disk(s) to be initialized by clicking the check box(es) next to the disk(s).
3.
Click
Initialize Selected

The
Rescan Disks
option rescans all channels searching for new or removed disks and rereads the
configuration information from each disk. Sometimes when a disk is offline, it can be brought online through a
rescan. Rescan also stops and then automatically resumes all tasks.
To rescan disks, from the
Disk
menu, select
Rescan
.

If the disks support this option, read ahead and write cache properties can be changed. The default settings
are to have read ahead and write-back caching enabled.
Caution!
Normally, you should not attempt to initialize disks that are part of an array, but it is possible
to do so unless the disk is part of the boot array.
Caution!
Leaving write-back caching enabled may increase the likelihood of data being corrupted
in the event that your system experiences a power interruption or unexpected shutdown.
Note:
You cannot change the disk cache settings if any tasks are active on arrays. The option is
enabled when the tasks complete.
