From 25d7c363f2663fe399e623c9bd819258c9760bdc Mon Sep 17 00:00:00 2001 From: Tony Battersby Date: Mon, 12 Nov 2007 10:00:44 -0500 Subject: [SCSI] move single_lun flag from scsi_device to scsi_target Some SCSI tape medium changers that need the BLIST_SINGLELUN flag have the medium changer at one LUN and the tape drive at a different LUN. The inquiry string of the tape drive may be different from that of the medium changer. In order for single_lun to be effective, every scsi_device under a given scsi_target must have it set. This means that there needs to be a blacklist entry for BOTH the medium changer AND the tape drive, which is impractical because some medium changers may be paired with a variety of different tape drive models. It makes more sense to put the single_lun flag in scsi_target instead of scsi_device, which causes every device at a given target ID to inherit the single_lun flag from one LUN. This makes it possible to blacklist just the medium changer and not the tape drive.
