Trying to remember (it was a long night).
I disabled all tape drive before halting the LM. After it booted I logged
in and checked - alll drives were disabled. I issued "disabled sessions
all", then enabled one tape drive. By the time I typed "q mount" it came
back with a tape being mounted!!! Maybe it somehow queued the mounts
before I disabled the sessions. If so, that brings up a catch 22 - you
need to disable the sessions before library sharing starts up.
Is there a way to start a tsm instance and have it run some commands before
it does anything?

Rick,
Were the tapes already mounted when you ran the command? I have used
those commands several times in the past during maintenance upgrades and
they worked flawlessly.

I tried a DISABLE SESSIONS ALL, but it didn't work. Tape mounts (via
server-to-server, I assume) still worked. I found this puzzling.

Hi Rick,
Try using the following commands which will disable all client and
server sessions to the TSM server:
DISABLE SESSIONS CLIENT
DISABLE SESSIONS SERVER
Hope this helps!

Subject: [ADSM-L] audit library problems
This past weekend we started the process of upgrading our TSM
environment from v5.4.1 to v.5.2.2. We have 2 dedicated library
managers (3584 libs) and 7 tsm library client instances and a bunch of
storage agents.
The first step was to upgrade _one_ of the library managers.
After we upgrade this library manager instance we hit APAR IC59453,
where drives would drop to a UKNOWN status and become unavailable. The
library manager would start working, then quickly degrade till it quit
servicing mounts. IBM support had us upgrade to patch v.5.5.2.1 to fix.
When this problem occurred the library managers view of the library got
messed up (ANR8300E) and required a AUDIT LIBR to clean up. And there I
hit frustration! Audit Libr cmd requires that the library be unused -
no processes/sessions have tape mounted. It also requires at least one
drive be online. If you issue the cmd before any drives are online,
it's process throws an error saying there are not online drives.
When this problem occurred and need to do a Audit, I would change all
the drives to online=no, halt/start the library manager, bring _one_
drive . . . and INSTANTLY a mount would occur for a library client
instance!! I would then issue the Audit Libr cmd (which waits for the
drive to become free) and work to get the process/session that has the
mount to end. This is SO FRUSTRATING. I had to do this multiple time
is working through this problem.
I asked IBM support if there was any way to tell a dedicated library
manager to STOP SERVICING client requests, and he said there isn't.
QUESTION: How can you effectively get a audit libr cmd to run in a busy
library sharing environment?
I came up with these ideas:
1) Drop all paths for a drive except for the the library manager itself
- giving a dedicated drive to the library manager.
2) Change the password on the server-to-server setup.
(wishful thinking invoked)
3) Get IBm to add a library client library online/offline function.
4) Get IBM to add a library manager online/offline function for
servicing mount requests.
5) Get IBM to allow audit libr to run without a online drive. (WHY
does an Audit need a drive online anyway? A audit is to the SMC device
for the library proper, not a RMT drive device).
