Resize Netapp Volume

[ablej]

Is it possible to resize a netapp volume that currently has LUN's with VMFS volumes. Is there any risk involved in this?

If you resize it, you wont be able to see the increased size from within your hosts without reformatting those LUNs.

Better to add a second LUN/VMFS. If thats not possible, add a second LUN and make it an extent of the first VMFS.

I was going to resize it to add space so I could create a new LUN. Will this cause any issues?

[mcowger]

That should be fine, as long as you are carving a new LUN out of that vlume.

You should be fine resizing a flexvol on the Filer. I do that regularly.

hi,

A LUN is very different than a volume in that its considered a FILE, not a filesystem. On netapp you can increase both LUN and volume on the fly. however with the LUN only Vsphere can take the increase on the fly. In 3.5 you would have to svmotion out of the LUN, increase it (rescan storage adapter) and svmotion back in again.

Given that a LUN is a file that resides in a container (volume) you are free to increase the container/volume (up to 16TB) and add LUNs

as you go along. Obviously adhere to best practices as you go along.

I have deleted my previous comment as it was for a different scenario.

cheers,

Eric

If you want to present a bigger LUN... clone the existing LUN to a bigger size and present that LUN to the hosts.

Otherwise resizing or extending the volumes are the options you have...

Hope this helps!!
