Sorry if this post is a bit off-topic as it may relate more to vmware than netapp but I'm hoping it relates enough to netapp that it's ok.

Scenario is: I have two netapp filers and both are being used solely for a single vmware cluster which has access to both filers for use as iscsi (and only iscsi) datastores. I need to move one shelf (aggregate) on one of the filers to the other filer. I'm comfortable with the netapp side of things but am unsure if anything special needs to happen on the vmware side for it to recognize the datastores now that they are on the other head.

I've simulated a test by snapmirroring a test datastore to the other head, unmapping the old lun, changing the lun serial of the new lun to the old luns, mapping the new lun back to the same lun id that the old lun was using and vmware was content with this (i.e. it saw the datastore as the original with all it's content). Will moving a shelf with several datastores to the other head work as well?

Thanks for any help.
