I would think that if the tape drive is under mpxio control then the backup s/w would see only 1 scsi_vhci path. I like the idea of having 1 active and 1 standby path to the tape drive. Even if the backup server has to restart the backup job it was working on at the time that is much better than having the tape drive offline until I replace the HBA. _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
