| |
After reset completed, the scsi error handler sends out START_STOP and TEST_UNIT_READY to the device. For 'normal' devices these commands will be handled by firmware. However, because the RAID console only interfaces to scsi mid layer, the firmware will not process these commands for it. This will make the console to be offlined right after reset. Add the handling in driver to fix this problem.
