VSERIES LUN MISSED CAUSES GENERAL PANIC AFTER TAKEOVER
o a V6000 with Ontap 8.2 7Mode a series of LUNs have been configured from an EMC CX4 system.
It happened that randomly a couple of LUN fail on the same raid group of the CX4.
The controller loose its aggregate that goes in degraded mode and a takeover start to the other node.
The other node after takeover attempt to put this aggregate online but if fails because one of its lun is still missed.
This panic all the systems and this should be avoided.
There are other third party arrays virtualized that should continue to work.
Is it possible to exclude from takeover actions only one aggregate (I think no), why the remaining node panic?
