Agreed, TSM is talking to the library. But the full libvol's are not
checked into it:
tsm: ITG-TSM>q libv
ANR2034E QUERY LIBVOLUME: No match found using this criteria.
ANS8001I Return code 11.

etc....
So I gather I need to checkin the libvol's into the "new"
library, right?
But I worried about that, because I've only ever used checkin libvol to
add scratch tapes, and these tapes are NOT scratch. Can you
verify that I
have the checkin command right:
checkin libvol lb6.0.0.5 search=yes status=scratch checklabel=yes
I'm only worried about the command because of the
status=scratch. I can't
have any of my volumes with data on them marked as scratch or else I'm
hosed. Do I have the command right?
Thanks Bill, I do appreciate it,
Alex

If it wasn't "talking" to the library, then you would get
errors. And audit compare TSM's LIBV inventory with the
library inventory.
If the library inventory is up to date, then the library
does not need to rescan the slots, but just returns the
inventory to TSM.
Plus you would not be able to define the drives with the
ELEMENT= if the library wasn't "talking" correctly. The
ELEMENT= number is
verified with the library. To see what elements and such you
can issue the SHOW SLOTS LB6.0.0.5 command. Another useful command is
SHOW LIBRARY LB6.0.0.5.
Have you tried to mount a tape and write to it? Or maybe
even just a checkin?

Subject: Re: tsm tape path problems
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

----------- ----------- ----------- -----------
-------
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!

One thing I have found with Windows is after any type of hardware
change, whether it is a replacement or just firmware
updates, Windows
seems to not recognize it as the same device, and creates
new ones for
this same (upgraded) hardware. If you just give the TSM
server a few minutes to time out on trying to initialize the
library, then
you can update the library path to the new device= and then
update the drive paths to the new device=.
I've started stopping TSM, removing the library/drives from Device
manager in Windows, doing the upgrade/replace and
rebooting. I've found that Windows assigns the same devices.
Then I just restart
TSM and verify that all is well.
I don't know if persistent mappings with the fibre adapter
(if you are running fibre drives) would resolve this issue...

Subject: tsm tape path problems
TSM 5.1.9.0 on win2K server. Overland Neo 4100 with 2 LTO-2 drives.
I've got a bad problem, and I'm stuck trying to read the manual for
clues but I'm having trouble finding what I need to know
and I could really use a point in the right direction.
TSM has been running just fine since I set it up more than
two years ago.
I used the TSM wizard to set everything up, and it was quite easy.
Last week we had an LTO-2 drive failure, some bad cables,
and an intermittent library controller card. All those hardware issues
have been fixed.
But somewhere in the mess of fixing all the hardware issues, the TSM
/windows drivers for the devices got confused, and TSM is now
recognizing the library and the drives as different device names.
Whereas TSM used to call the devices: lb6.0.0.3 (library),
mt1.0.0.3 (drive 1), and mt2.0.0.3 (drive 2); TSM is now
calling those devices lb6.0.0.5, mt1.0.0.5, and mt2.0.0.5.
I've tried everything I know of to fix the path between the
server and the "old" devices (lb6.0.0.3), but nothing I tried worked.
So, I then set out to try and define new path's for the
"new" devices (lb6.0.0.5). I've done the following:
- Define the new library and drives, giving them the proper names
and element ID's.
- Update the server's LTO Device Class, giving it the new
library name
lb6.0.0.5.
- Add the new path's for the drives and the library:
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 then I try to run an audit of the new library, and I
get nothing:
ANR2017I Administrator ALAZAREV issued command: AUDIT LIBRARY
lb6.0.0.5 ANR0984I Process 5 for AUDIT LIBRARY started in
the BACKGROUND at 21:42:02.
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 21:42:02.
The audit did nothing, as it starts and completes within a
second. The library didn't move an inch.
Obviously, I'm not setting up the paths properly, or the devices
classes, or something. What I find odd is that when I run the Device
Configuration Wizard, TSM does not find any devices. That
is different from when I first installed TSM, when it found all devices
automatically for me.
I'm going to read Chapter 4 of the admin guide tonight when
I go home,
but I've already looked at it, and I can't find the
information I need
described in a clear manner. Any help anyone could provide,
even just pointing me to some good documentation, I would appreciate
it.
Sorry to be a pest, but I'm in trouble, as our backups are
down and I need a little help getting it back up.
Thanks in advance,
Alex
