I thoguht this also, initially. But does the 'checklabel=yes' parm force
the library to mount the tape? I havent been able to test this as our
libraries are busy.

I don't know about your library, but on an IBM 3584 library, a tsm
'audit library' command will just reconcile its libvol data with the
data the library maintains. It does not move any parts in the library
because the library already has a record of which tapes are where.

William, et all,
Thanks for your great responses, I think I'm closer to getting it
working,
but I still need a little more help.
I understand what you are saying about updating the paths, but the
problem
is I already removed the old paths and devices (xxx.0.0.3), and created
the new devices and paths (xxx.0.0.5). So I think doing an update path
is
out of the question. I'm stuck trying to associate the new devices with
the old server, which should be possible right?
So, I've removed all devices and paths, rebooted, then added all devices
and paths (for the xxx.0.0.5 devices), rebooted again, and now TSM seems
to think the devies and paths are correct:
tsm: ITG-TSM>q library
Library Name: LB6.0.0.5
Library Type: SCSI
ACS Id:
Private Category:
Scratch Category:
External Manager:
RSM Media Type:
Shared: No
LanFree:
ObeyMountRetention:
tsm: ITG-TSM>q drive
Library Name Drive Name Device Type On-Line
------------ ------------ ----------- -------------------
LB6.0.0.5 MT1.0.0.5 LTO Yes
LB6.0.0.5 MT2.0.0.5 LTO Yes
tsm: ITG-TSM>q path
Source Name Source Type Destination Destination On-Line
Name Type
----------- ----------- ----------- ----------- -------
ITG-TSM SERVER LB6.0.0.5 LIBRARY Yes
ITG-TSM SERVER MT1.0.0.5 DRIVE Yes
ITG-TSM SERVER MT2.0.0.5 DRIVE Yes
But something is still not right, because when I run an audit of the
"new"
library, the process completes, but it does nothing to the library, the
library doesn't move in inch, it is not talking to the library
correctly:
ANR2017I Administrator DUDE issued command: AUDIT LIBRARY lb6.0.0.5
checklabel=yes
ANR0984I Process 5 for AUDIT LIBRARY started in the BACKGROUND at
09:41:03.
ANR8457I AUDIT LIBRARY: Operation for library LB6.0.0.5 started as
process
5.
ANR8461I AUDIT LIBRARY process for library LB6.0.0.5 completed
successfully.
ANR0985I Process 5 for AUDIT LIBRARY running in the BACKGROUND completed
with completion state SUCCESS at 09:41:03.
I'm wondering if my device class is not correct in some way?:
tsm: ITG-TSM>q dev
Device Device Storage Device Format
Est/MaxMount
Class Access Pool Type
CapacityLimit
Name Strategy Count (MB)
--------- ---------- ------- --------- ------
--------------
DISK Random 3
LTOCLASS1 Sequential 1 LTO DRIVE
DRIVES
Any other ideas?
Thanks!

Whereas TSM used to call the devices: lb6.0.0.3 (library),

devices lb6.0.0.5, mt1.0.0.5, and mt2.0.0.5.
