MSA raid volume expansion, extend lun question

[anand narine]

Hi all,
I have a single Raid 5 volume that is split into 2 luns. Lun A is presented to Server A and Lun B is presented to Server B. Lun A is running out of disk space, so I want to add more drives to the raid 5 volume. Can I expand the volume ? and can I extend the Lun A so that windows see more disk space available ?

Wich MSA?

If it is a Smart Array based MSA ei MSA1000/1500), then the answer is no.
You can extend Logical drive B, not A.

If it is a MSA2000, it should be possible.

Note.
In case of a Smart Array.
I assume, you mean, that you've got 1 array (Array A) with 2 logical disk's that is RAID 5.

Different technologies use diferent terms.

It's an MSA 2312fc

MSA2312fc. Can you provide information on how to expand the volume/array ? If the array is expanded, how can I then extend the lun afterward?

I will recommend that you download the reference guide. And read it carefully.

First you must expand the VDISK
Second you must expand the volume.

Select.
Provisioning > Expand vdisk
go on from there.

Select
Tools > expand volume
go on from there.

Again download the reference guide and read.
