Managing the Disk Array Using SAM
5. Click the LUN # button and select the desired number for the LUN. You can also enter
the LUN number directly in the field.
6. Click the RAID Level button and select the desired RAID level for the LUN.
7. Select the disks to include in the LUN. All unassigned disks are identified with a status
of white.
As you select disks, the capacity of the LUN is calculated and displayed, and the disks
are added to the Selected Disks field. When creating a 0/1 LUN, the Selected Disks field
identifies the data disks in the upper portion of the field and the associated mirror disks
in the lower portion (below the
<<<MIRROR>>>
separator). See "Selecting Disks for a
RAID 0/1 LUN" on page 243 for more information.
8. Click the Stripe Size button and select the stripe element size. You can also enter the
stripe size in the field. The stripe size must be a multiple of the current cache page size.
If you enter a value that is not a multiple of the cache page size, the value will be rounded
up to the nearest correct value.
9. In the LUN Owner field, select the controller that will own the LUN. LUN ownership
should be balanced between controllers for optimum performance.

K
to bind the LUN and exit the screen, or click Apply if you have additional LUNs
to bind.
Note
After binding a LUN, you must execute the
insf -e
command to install special
device files for the LUN. This makes the LUN usable by the operating system.
