Hi folks, I've been pokeing in scsi_id trying to understand the
serialnumber part.
I don't understand the choices patrick made in doing this.
My note to patrick follows:
Hi patrick,
I'm trying to undertstand your scsi_id program.
I'm testing on an LTO drive and the code
seems to call
do_scsi_page83_inquiry() which returns the (not really) serial number.
Why are you doing that? The page is.
sg_inq -vpd --page=0x83 /dev/st2
VPD INQUIRY: Device Identification page
inquiry cdb: 12 01 83 00 fc 00
inquiry: requested 252 bytes but got 42 bytes
Designation descriptor number 1, descriptor length: 38
id_type: T10 vendor identification, code_set: ASCII
associated with the addressed logical unit
vendor id: HP
vendor specific: C7438A HU107108XD
Why not get the real serial number from page 0x80??
sg_inq -vpd --page=0x80 /dev/st2
VPD INQUIRY: Unit serial number page
inquiry cdb: 12 01 80 00 fc 00
inquiry: requested 252 bytes but got 14 bytes
Unit serial number: HU107108XD
close error: No medium found

Anyone know where he is?
He is not working for IBM anymore.
If you have a scsi_id question you can post to this list as scsi_id is
maintained as part of udev extras.
