We have had several clusters that have worked fine over take overs (just went through 6 panics after upgrading to 7.2.6!)., but since you mention igroups - I assume you are using iscsi for the luns. We are using fcp.
I assume you are using 3 seperate network interfaces for iscsi traffic and the intra cluster and public traffic?

Hi guys, im seeing this behavior on different MS windows clusters attached to our FAS960, the most weird part is that i see the active node of the windows cluster connected to the target portal, but from the filer i dont see the igroup logged in for almost 2 minutes and thats when the windows clusters hung because they cant mount the quorum lun. All these while doiing a cf takeover.
I talked to probably 10 Netapp support engineers and no one can explain it.
Has anyone seen anything like this before? I have installed Host Utilities 5 and checked the windows registry to make sure the values have been tuned.
Thanks
