Looks like we have had power down at night. Afterwards, the scsi tray was
in a strange state - the system BIOS didn't find anything on the bus, and
naturally the linux driver didn't either.

After we power cycled scsi tray and rebooted the system, the system BIOS
detected all the scsi devices but the linux driver still was blind.

It said something about timeouts during lun probing and marked all the
devicess offline, and we tried it via reboot/powercycle of the system at
least 2-3 times.

After we setup the old driver everything went fine.
