EVA 4100 extending vdisks

SteffenG — Mon, 07 Jun 2010 14:06:06 GMT

Hi.
I have 2 EVA 4100 which is running out of space in some vdisks. I'm running Veritas SFHA 5.0 ontop of these for clustering/mirroring

And I have other disks with plenty of space.

Can I just type in the new sizes in the CV, and thereby reduce some vdisks, and increase others ??

Thnx
Steffen

What version of XCS is running on the EVA?

As far as I know, you can not decrease the size of s vdisk on an EVA4100, you can only increase the size.

If you have available space in the disk group where the vdisk lives, you can certainly add space to it without affecting anything else... (except the total amount of free space you have to use ;o) )

You'll have to rescan and make sure the disk manager recognizes the space afterwards...

So basicly I can use whatever unasigned disk space in the group, and just increase the existing vdisk.
And if needed add more new disks to the group.

NOT decreasing other existing vdisks.

(it has been a few years since I woorked with this kind of systems....)

Also planning to upgrade to CV 9.2 (from 8.0.1)

From the EVA side you can seamless grow an existing virtual disk to up to 2047 GigaBytes, but I would check if Veritas can deal with that.

Hi,

If you have Enough free space in the disk group, Then you can increase the vdisk space through CV EVA, simply typing the new vdisk capacity in GB.

In general, EVA can reduce vdisk size, but there is no guarantee in data. So make sure that you have full data backup before
reducing vdisk size in EVA.

Vdisk shrink is possible since XCS 6.1xx and Command View 8.0.

Check the EVA Compatibility reference:

http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02128483/c02128483.pdf

Another thing is that the OS can handle it (check the PDF).

Increasing the size of a vdisk will not decrease the size of others, you have to do all changes manually.
