+From: Jeremy Higdon <jeremy@sgi.com>
+Subject: mptsas driver fails to discover devices
+References: bnc#459932
+
+The mptsas driver has a serious regression in sles11rc1 in that it fails to
+discover devices that work fine with sles10sp2.
+
+I discovered that part of the problem was that the target number of the RAID
+volume was too high for the driver to discover it.
+
+The problem with the IS220 (LSI 1333 RAID) is that the driver is issuing its
+own Test Unit Read and that's apparently being considered a failure from the
+Unit Attention statuses.
+
+With this patch the system boots okay.
