Thanks for the response. I did a failover test by disconnecting ethernet cables yesterday. It didn't behave the way it was supposed to. Likely there's something wrong with my multipath configuration. I'll have to review it, but that's why I have a test server. I was concerned about simultaneous SCSI commands over the two paths that might get executed out of order, but something must ensure that that never happens. -- -Gary Mills- -Unix Support- -U of M Academic Computing and Networking- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
