From d116a7bc6ab4dcf752078daeaf2276f7d7660595 Mon Sep 17 00:00:00 2001 From: Ed Lin Date: Wed, 9 May 2007 20:50:40 -0800 Subject: [PATCH] [SCSI] stex: fix reset recovery for console device After reset completed, the scsi error handler sends out TEST_UNIT_READY to the device. For 'normal' devices the command will be handled by firmware. However, because the RAID console only interfaces to scsi mid layer, the firmware will not process the command for it. This will make the console to be offlined right after reset. Add the handling in driver to fix this problem.
