From 905bd78f2188da69e74966918e3d71df3dff382b Mon Sep 17 00:00:00 2001 From: "scameron@beardog.cca.cpqcorp.net" Date: Fri, 19 Sep 2008 18:27:47 -0700 Subject: cciss: Fix cciss SCSI rescan code to better notice device changes Fix cciss SCSI rescan code to better notice device changes. If you hot-unplug a tape drive, then hot-plug a different tape drive into the same slot in a storage enclosure, the cciss driver wouldn't notice anything had changed, as it was only looking at the LUN address and device type. Now it looks at the inquiry page 0x83 device identifier, and vendor and model strings as well. Signed-off-by: Stephen M.
