IBM TS3310 / HP-UX 11i v1 / Legato

[Stuart Walker_1]

I have an IBM TS3310 Library with (2) LTO-3 drives that are SCSI attached to a C8000 running HP-UX 11i v1. I've installed atdd.3.5.0.44.bin and tapeutil.hpux.4.2.7.0.bin IBM drivers. 'swlist' shows;
*atdd 3.5.0.44 GES IBM tape and changer device driver for TotalStorage

*tapeutil 4.2.7.0 IBM HP-UX Tape Utility Program

The devices show up as;

To me, that all looks good.

When running 'inquire -lc' for Legato device discovery/configuration though, none of the devices show up. All that shows up is the DVD-ROM and the internal SCSI disk.

Has anyone seen this before or have any ideas on what the problem could be?

As an update to this...

IBM indicates to NOT use the IBM drivers. So, I've uninstalled those and am now using 'stape' and 'schgr' drivers;

autoch 6 0/0/1/1.4.1 schgr CLAIMED DEVICE IBM 3576-MTL

There are no device files for the autoch now. I assume that I am going to have to do a 'mksf' to create one...

I forgot to mention that Legato is Networker v7.2.2.

The Legato support guys say that it is a problem with the HP SCSI pass-thru driver, though couldn't explain much beyond that...

[Stuart Walker_1]

Here is the answer;


Basically, new device files must be created for the changer and for all the tape drives using the Major Number of the SCSI pass-thru driver (SCTL).

Rebuilding cached SCSI device list /tmp/lgto_scsi_devlist, this will take a few moments.

Done.
