Ok, attached is my 60-persistent-storage-tape.rules
adding |nst*[0-9] seems to have fixed the issue.
my tape/by-id/ looks like
HP-C7438A-4855310710385844 -> ../../st4
HP-C7438A-4855310710385844-nst -> ../../nst4
HP-Ultrium_1-SCSI-HU84H06998 -> ../../st3
HP-Ultrium_1-SCSI-HU84H06998-nst -> ../../nst3
HP-Ultrium_2-SCSI-HUL3K02633 -> ../../st2
HP-Ultrium_2-SCSI-HUL3K02633-nst -> ../../nst2
QUANTUM-DLT8000-PXB23P0605 -> ../../st1
QUANTUM-DLT8000-PXB23P0605-nst -> ../../nst1
QUANTUM-DLT8000-PXB23P0632 -> ../../st0
QUANTUM-DLT8000-PXB23P0632-nst -> ../../nst0
STK-L80-LLC02205205 ->../../sg1
which in my opinion is a huge improvement, since I can see which drive
is which and the serial number matches up with the serial number shown
by tapeinfo.
I think that should be the standard.
The USB drive (C7438A) is now consistent between st and nst, however the
serial number is HU107108XD not 4855310710385844.
I have no idea how to fix that since the rules now use things like bsg
and usb_id %p which are entirely undocumented.

John

Now my scsi tape drives are all identified nicely, (thankyou)
I'm looking at my USB tape drive.
Its st and nst incarnations are getting different /by-id/ info.
HP-C7438A-4855310710385844 -> ../../st4
HP-C7438A-HU107108XD-nst -> ../../nst4
The problem seems to be
KERNEL=="st*[0-9]", ENV{ID_SERIAL}!="?*", SUBSYSTEMS=="usb",
IMPORT{program}="usb_id --export %p"
but that won't pick up nst*, as the later rules do.
Also applys to the 1394 tape drives.
Care to adapt the rules to work on your box, then we can start from there?
Thanks a lot,
Kay
