ZFS needs to use the top level multipath device or bad things will probably happen in a failover or in initial zpool creation. Fopr example: You'll try to use the device on two paths and cause a lun failover to occur. Mpxio fixes a lot of these issues. I strongly suggest using mpxio instead of powerpath but sometimes its all you can use if the array is new and mpxio doesn't have the hooks for it ... yet. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
