Hi,
we recently updated ONTAP from 7.2.5.1 to 7.3 on our 3140c, which led to many problems : one head doesn't boot anymore, so the cluster failover is impossible; the other head (currently in takeover) seems to reboot randomly every week; and when this happens, it freezes some of our RHEL4 servers (kernel panics, somewhere in lockd).
Putted shortly: this is a mess.
The issues are currently investigated by NetApp, but it may take some time until we see a corrective action on their side. So we're investigating another solution, which would be to downgrade back into 7.2.5.1 (since it appears 7.2.6 doesn't seem very stable either).
Would any of you know how to do that, or could point me at a proper procedure somewhere? NetApp support was unresponsive on this one, and I'm a bit concerned about possible changes to the WAFL layout or something similar between 7.2 and 7.3.
