Disk Expansion in Model 30/FC


I am having a Model 30/FC with 29 Disks 5*18GB and remaining 4*GB disks with 4 LUNs which is as follows:-

15* 4GB Disks in LUN0
5* 4GB Disks in LUN1
4 * 4GB DISKS in LUN2
4 * 18GB Disks in LUN3
1 * 18GB DISKS Hotspare

Now I want to upgrade two disk modules with 18 GB Disks.

Is there any possiblity of expanding the existing 18GB LUN (LUN3) without data loss

Also I want to downsize a 4GB LUN and replace with a 18GB LUN. Is it possible?

If so can any one please give a procedure for the same

Re: Disk Expansion in Model 30/FC


it is not possible to extend an raid-array in your 30/FC.
You have to unbind your lun and recreate it with the drives you want in the config.
All data will be destroyed due to this action!

Re: Disk Expansion in Model 30/FC

you can upgrade the LUN via the prompt you get with Ctrl [] [] [] [] [] []

but it's not so easy.. and really only for expert use. I'd recommend unbinding and rebuilding.

Note my replies in this question for info on lun configuration:,,0x82b6d06ed8c8d4118fef0090279cd0f9,00.html

It works for me (tm)
