Netapp OnTap NDU - problem with Hyper-V cluster

hrm, then options comes with 8.1+ maybe, dont have an older ontap to check atm.

kb is the right one, it shows you REV_736 vs REV_0.2 as an example of the string change.

So how to prevent the revision number change on ontap8.0.2? Is it possible w/o the igroup option?

If it is not possible ... when go the LUNs offline? Right after the ontap upgrade (to 8.0.4) or after the server reboot? I need to be 100% sure about this.

afaik its not possible. you need to do a disruptive update, eg get the datastores online after the update. i think (not 100% sure) the version change happens on giveback as the new updated filer will then continue to serve the luns.
