From 13f7e5acc8b329080672c13f05f252ace5b79825 Mon Sep 17 00:00:00 2001 From: Kurt Garloff Date: Mon, 3 Apr 2006 15:20:08 +0200 Subject: [SCSI] BLIST_ATTACH_PQ3 flags Some devices report a peripheral qualifier of 3 for LUN 0; with the original code, we would still try a REPORT_LUNS scan (if SCSI level is >= 3 or if we have the BLIST_REPORTLUNS2 passed in), but NOT any sequential scan. Also, the device at LUN 0 (which is not connected according to the PQ) is not registered with the OS. Unfortunately, SANs exist that are SCSI-2 and do NOT support REPORT_LUNS, but report a unknown device with PQ 3 on LUN 0. We still need to scan them, and most probably we even need BLIST_SPARSELUN (and BLIST_LARGELUN). See the bug reference for an infamous example. This is patch 3/3: 3. Implement the blacklist flag BLIST_ATTACH_PQ3 that makes the scsi scanning code register PQ3 devices and continues scanning; only sg will attach thanks to scsi_bus_match().
