[PATCH] Make SCSI-system aware of type 12-devices

[PATCH] Make SCSI-system aware of type 12-devices

[Thomas Langås]

This small patch doesn't display "Unkown" when a type 12 device is found,
when scanning for scsi-devices on a scsi-chain. I also included the 
declaration of TYPE_PRINTER which wasn't there. All theese types are
described in ftp://ftp.t10.org/t10/drafts/spc/spc-r11a.pdf page 51, 
table 21.

Yeah, however nobody tried to implement SCC command class before.
It is much easier for a controller vendor to provide REPORT_LUNS
(which is enough to find volumes), and have some out-of-band
management interface - front panel, telnet, or a web form.
Out of curiousity, what is your hardware?

The patch looks ok.

This controller has a consolle which you can hook up to, to do management.

Compaq StorageWorks (announced vendor is DEC, tho) HSG80.
