Performing Common Tasks
When the stripe unit size is 8 K or 16 K, the
maximum number of drives in an array is 16. When
the stripe unit size is 32 K or 64 K, the maximum
number of drives in an array is 8.
4. Use the Up Arrow (↑) key or the Down Arrow (↓) key to
highlight the RAID level you want to assign to these logical
drives; then press Enter.
Note: Because the level you assign can influence the space
needed for the drive, you must assign a RAID level
before you enter the size of the logical drive.
The Logical Drive list contains the logical drive ID, the size of
each logical drive, the RAID level you assigned to that logical
drive, and the date that the logical drive was created.
The status of the logical drive also is shown. OKY means that
all is well with the drive. CRT means that you must replace the
hard disk drive or rebuild the logical drive. (You will have
received a message during system startup telling you what has
happened to the drive.) OFL means that the logical drive is
irrecoverable; the data on that drive is lost.
If this is the first logical drive to be defined, the Logical Drive
Size pop-up window shows the space in the array that is
available for 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.
5. Type the size, in megabytes, that you want for the logical drive;
then press Enter. A pop-up window appears, asking you to
confirm your action.
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 drives in the
array.
