(You will receive a message telling you the drive is in a CRT
state if you are running the Administration and Monitoring
program.) OFL means that the logical drive is unrecoverable;
the data in that drive is lost.
If this is the first logical drive to be defined, the Logical Drive
Size pop-up window shows the amount of space in the array
that is available for additional logical drives.
If other logical drives have been defined, the Allocation Table
appears, showing the logical drive sizes already created, and the
amount of free space available.
6. Type the size, in megabytes, that you want for the logical drive;
then press Enter. The Confirm pop-up window appears asking
you to confirm your action.
The information about the new logical drive appears in the
Logical Drive list.
Note: The size appearing in the Logical Drive list might be
different from the size you typed. The size of a logical
drive is determined by a number of factors, but basically
the size must be divisible by the number of data drives in
the array.
Consider the following scenarios:
Scenario 1
The array consists of three 1 GB drives. You assign RAID level
0 (which uses all the drives in the array with no parity storage),
and type
1ððð MB
. The number in the Size (MB) field will show
999, which is the number closest to and lower than 1000 that is
divisible by 3.
Scenario 2:
The array consists of three 1 GB drives. You assign RAID level
1, which provides a disk mirroring that stripes data across all
drives in the array. Because the data is mirrored, the capacity of
the logical drive is 50 percent of the physical capacity of the
hard disk drives grouped in the array. Type
1ððð MB
; the
number in the Size (MB) field will be 999. The physical capacity
used is 2000 MB, twice that of the logical drive size. The
