[ bounced back to -SCSI, since this is actually a bona fide SCSI question ]
You know, I've always wondered about this...
Whenever someone posts dmesg output on one of the lists, I always look at it
just out of curiosity. and in many cases I have seen the serial number of
SCSI disks printed out. (heck, I seeem to recall once seeing an IDE disk
print its serial number.)
But in none of my systems am I getting any serial number output.
One of my boxen, a PII400 (Abit BX6 R2.0 motherboard) has an Adaptec
AHA-2940U2W controller, to which I have just added a brand-new, shiny IBM
DDRS-39130 9GB LVD disk to it... and yet I get no serial number! (see dmesg
below)
Am I doing something wrong? do I need to enable any kernel config options
for serial numbers to print? (the only SCSI options I have enabled are
SCSI_REPORT_GEOMETRY and SCSI_DELAY) Or am I just cursed? :)
Enquiring minds want to know!
