Vol move between aggr, cutover timeout

[martinrudjakobsen]

Hello.

I am trying to move a 4TB volume with a LUN from one aggregate to another to spead out load onto more disks. However I get timeouts all the time at cutover time. I have been unable to figure out why this happens but I am guessing it takes too long time.

Thu Aug 23 12:45:41 CEST [157015:vol.move.transferStart:info]: Update from volume 096_LUN02_vol to ndm_dstvol_1345454051 started.

Thu Aug 23 12:50:06 CEST [157015:vol.move.cutoverStart:info]: Cutover started for vol move of volume 096_LUN02_vol to aggr aggr11.

It's on " NetApp Release 8.1 7-Mode".

Any suggestions welcome.

Hi Martin,

Have you got SnapMirror licensed? Did you try using it to move the volume?

Hi,

Yes I have snapmirror licensed and I can see it transferring when I use the "Snapmirror status" command.

So instead of doing vol move, try creating new volume (in the target aggregate) & SnapMirror the content from the old one to the new one.

Some additional info re LUN serial numbers could be found in this thread:

Yes, but then I wouldn't be able to do it without taking it offline?

Anyway I seemed to have solved my problem by increasing the cutover window to 300 seconds and crossed my fingers the server wouldnt throw a fit(it isnt mission crititcal).

Thanks.
