Subject: Deleting & building LUNs.
FYI.
Deleting LUNs
1) Right mouse click on the controller that is listed in the
system view.
2) Left mouse click on configure.
3) Select the custom and edit configuration.
4) Select the logical drive (next button).
5) Select delete last until you reach the required LUN.
6) Select the drive spares menu (next button).
7) Select next until the LUN mapping window appears.
Select OK.
A warning appears that states you are about to delete a LUN.
Select yes.
When a second window appears, select yes and OK; the
controller reboots.

Building LUNs
1) Right mouse click on the controller listed in system view.
2) Left mouse click on configure.
3) Select custom and new configuration.
This displays a window that lists the drives that are
available to configure.
4) Click on new array. This displays a window where you can
select the drives.
5) Click on the drives that you want in each array.
6) When you have the desired number of drives selected, click
new array and repeat Steps 4 and 5 for all arrays.
7) When you complete the selection, enter NEXT. The logical drive
window will appear on the screen.
8) From the logical drive window, select the RAID level and
stripe-block size; then initialize and write the cache
(if desired).
Enter add; the name increments by one.
Select the next RAID type; then enter add.
Repeat this process until all RAIDs have been added.
9) Enter next; the spare drive window appears on the screen.
Click on each drive that you want to add as a hot spare.
10)Click next; the LUN mapping window appears on the screen.
Click on set sequential;
11)Set Topology to Multiport; then click on OK.
12)The controller resets and a window appears that displays
the LUN percentage that is being bound.
Note: Step 12 takes a long time because parity is built across
each LUN.
