Subject: Re: cf takeover hungs Microsoft Windows Clusters

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?
