Fig. 7.8 Logical Drive Preferences Screen
After all member drives have been selected, press [ESC] to continue with the next option. A
list of array options is displayed.
Maximum Drive Capacity
Fig. 7.9 Maximum Drive Capacity Screen
As a rule, a logical drive should be composed of drives of the same capacity. A logical drive
can only use the capacity of each drive up to the maximum capacity of the smallest member
selected for the array.
Assign Spare Drives
Fig. 7.10 Assign Spare Drives Page
You can add a spare drive from the list of the unused drives. The spare chosen here is a Local
spare and will automatically replace any failed drive. The controller will then rebuild data onto
the replacement drive.
A logical drive composed in a non-redundancy RAID level (NRAID or RAID 0) does not support
spare drive rebuild.
Disk Reserved Space
The reserved space is a small section of disk space formatted for storing array configuration
and RAIDWatch program data. This item is for display only—you cannot change the size of the
reserved space.
