what about the pagp and lacp and jumbo packets. I agree it sounds like a networking issue.

Two minutes eh? Sounds a lot like ARP issues. How is portfast/etc set on the switch ports?

Hi Jack, we are using 2 standalone interfaces for iscsi, and a team of 2 interfaces for intra and cluster traffic.

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
