Our Vsphere cluster is identified by a single iGroup on the netapp target end. Unfortunately, this igroup was set to ostype linux at creation. When trying to mount a snapshot of a cluster datastore using smvi 2, I get an error saying that the ostype isn't vmware. Does anyone know if doing an "igroup set [igroup name] ostype" command on the existing igroup is disruptive or not? It would be nice to not have to take down all guests to make this change.
Thanks for answering. The igroup you changed was for the ESX host connections, correct? I can't believe that no one has had this issue. Netapp wasn't able to give me an positive answer one way or another.
The change should be non-disruptive unless you have the same initiators as part of an igroup in partner node...In case of having the initiators as part of an igroup on partner node, it will be a disruptive change(in single image mode-which is default now) as you need to remove the igroup from partner and make the necessary changes.
changing igroup will make scsi behaviour change on the host for a brief period which may not be noticable...so it should be non-disruptive.
