Hi,
I would like to add a few lines to the SCSI scanning code to retrieve
WWID and/or serial number from pages INQUIRY pages 0x83 and 0x80.
I'm aware that this can be done from userspace. I've done it before
(scsidev). However, you need some code to relate device nodes
(sg, sd) to device IDs (C:B:T:U), thus it's non-trivial to do.
Thus, IMHO, it would be good to retrieve WWID and/or serial no
and export it via sysfs to make persistent device naming in userspace
easier. The USB subsystem already does it.
Regards,
