Forgot to say, we are using regular ethernet cards for iscsi connections.

Are all HBA’s (on all MS cluster nodes) zoned in?

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

Chris
