Simple eva3000 Question

[CRDavies]

Hi, just a nice and simple question..

I am needing to expand a vdisk on our EVA3000 SAN. Without HP Volume Growth software, how do I go about expanding the vdisk on the fly?

Best Regards

Hi,

If your os doesn't support extending a disk then it will not work. In your case you don't have HP Volume Growth.
So it is better to add an extra vdisk and add it to your OS partition

We are running Windows 2000 server. So the os will allow it..the diks are basic. Can I just resize from the os then? or would I need to adjust the size of the vdisk in EVA command view before I can then extend the disk in windows.

Apologies for my lack of eva knowledge...

Thanks for your help.

Hi,

first backup your data, just in case.
In Command View EVA, type in the new (larger) size for your Vdisk. Wait until the Vdisk has been fully expanded on the EVA . After this Windows' Disk Manager will see that the disk is bigger and the new space is "Unallocated". If you have just one partition on the disk, then it's no problem to extend this partition using diskpart (in the Windows 2000 Resource Kit)
For example, in Disk Manager, the disk is called Disk 3 and has a single partition F:, start diskpart from the command line and then use the following commands.

SELECT DISK 3
SELECT PARTITION 1
EXTEND

And hey Presto, F: has been extended! See Microsoft's Website for more details on how to use DISKPART.

Note: this only works for Windows. I don't think Unix would support dynamically growing a disk on the EVA. For that you would need to use Luk's suggestion.

Get the DISKPART utility from Microsoft - the address used to be:
http://www.microsoft.com/windows2000/techinfo/reskit/tools/new/diskpart-o.asp

but it seems to have moved. It should be in the W2000 ressource kit.
