RE: Linux and tape drive serial numbers.

Rob, is there anything that can be done in the LPAR properties to force
the devices?

Or maybe just some way of disabling the Linux autoconfig so it doesn't
try to re-detect/configure at partition start-up?

Thought of that, but I'm rather a newbie at TSM and I've not figured out
how to script that into TSM.  I know it supports it though.  I've shot
this off to the TSM list a few times but I don't think they have much
tolerance for the newbies.  Translating to i5 terminology I'm almost at
the level of wanting a reply like STRSEU enter in commands
F3
Type in CRTCLPGM and all the parameters detailed out.
Now, add this to a menu by ...

My brief experience in touching vi for linux in a phone call from IBM
made i5/os's EDTF for ifs files look pretty easy.

Re: Linux and tape drive serial numbers.










I'm not an expert and don't even play one on TV but could you write a
program that runs as a startup job when you IPL to retrieve the serial
numbers for each device (however they get assigned) and have the program
plug them into TSM?  It's not a great solution but it might get you past
were you are at.  Just a thought...

I have a Linux lpar hosted by an i5/os lpar.  Suse Linux.  V5R4 of i5/os
host.  i5-570.  The Linux lpar is using a 3582-L23 tape drive connected
to
a 5704 fiber card via a IBM SAN switch.  In the /dev directory there are
a
few devices:
IBMchanger0 for the 3582 library
IBMtape1 for one drive
IBMtape2 for the other drive

 I ran the following:
IBMtapeutil -f /dev/IBMtape1 inquiry 80
and
IBMtapeutil -f /dev/IBMtape2 inquiry 80
These commands will display the serial number of each drive.  You can
check that out using the buttons on the 3582 to compare.  The problem is
that I then rebooted this Linux lpar.  I ran the IBMtapeutil commands
again and the serial numbers flipflopped between the two.
I am using IBM's TSM software and when you configure the tape drives it
records the serial number.  The problem is now I have to reconfigure the
tape drives into TSM after every reboot.  (As if our downtime
instructions
weren't complicated enough, right Dave?)  I am thinking the possible
solutions are either to get Linux to stop flipflopping the serial
numbers
or to tell TSM not to give a rip about the serial numbers.  Trouble is,
I
can't figure out either way.  I have a pmr open with IBM on this, but
it's
not getting anywhere fast.
