missing tape dev-files in /dev/rmt

Inesa Clinko — Tue, 14 Oct 2003 01:45:03 GMT

Hi!
I cannot find my DLT SureStore device files.
The device is connected,the tape is plugged.
But I cannot do make_recovery:
#make_recovery -A -C
because my dev-file is missing in /dev/rmt

I tried to find it with ioscan and insf,
but I cannot find files in /dev/rmt-directory
such as in other mashines. Ignite is also present on my mashine /rp8400, hp-ux 11.11/ What is missing: another software or
anything else?

Normal procedure here is to do "ioscan -fnC tape" and see if the tape drive is CLAIMED. If it is then run "insf -e -C tape".

That should re-create all the device files and they will probably be in /dev/rmt

If the tape was connected during bootup
just do a
#insf -e

Thanks for your responces, but as you
can see above, I have already used insf.
The problem may be is in missing kernel-drivers?

What is the ouput of

#ioscan -fnC tape

Were the tape drives previously connected to this machine? Were the device files there previously and they've now disappeared?

I'm guessing that you've just connected the tape drive(s) and you have a SCSI conflict, like a F/W device connected to a SE HBA, or a HVD/LVD conflict. Until you get the device(s) connected properly the system won't recognise them. You're also risking damage by connecting them to the wrong HBA.

I fully agree with Pete. Even if there're no drivers installed ioscan should show 'something' UNCLAIMED UNKNOWN on the path. If it does not see anything, then there's connectivity problem.
Check if your drive HVD or LVD. If it's LVD, you can connect it to any LVD port of the server (checking its SCSI Id prior of course), but if it's HVD you need HVD card (like A4800A)
