Hey Jason if you want to get me an lsscsi output I can probably whip up a multi-path.conf block for your customer or talk to them on the phone if you like.

Trying to help a customer resolve a multipath.conf issue....
I am at a major stopping point regarding my deployment on Linux.   I’m working with our SAN Team to get a good /etc/multipath.conf configuration with a stanza for our EMC V-max SAN presented.      I have PowerPath installed and the SAN disk can been seen from both linux nodes but I need to set three items in a custom devices stanza to ensure no disks locking.    The three items required for concurrent disk without locks are:   feature=0,   failback=immediate & no_path_retry=fail.   If you were to reply with an example of the multipath.conf where you’ve used EMC V-max I would just be tickled pink.

Thanks.
