exchange client does not backup the file qmanager.dat
does anybody seen this before?
thanks.
Hi list,
i have a question about SAN design.

enough ports
to connect all units.
But a cutomers describe a problem with tapeunits in one san (disk+tape). When he

hello,
we would like to upgrade our tsm server os from w2k to windows 2003.
which is the recommended way to do this?
new installation of windows 2003, tsm software, drivers and taking over
the original dbvols and logvols?
or
migrate w2k to 2003 without take care of existing tsm server
Hi,
we tested a migrate install from w2k -- w2k3 using TSM 5.2. The upgrade itself
was no problem, tsm started without any problems.
We had to go and reconfigure all devices though because w2k3 uses different LTO
drivers (our environment).
You have to install the drivers through the w2k3 devices
Hello everyone!
I was just wondering if it is necessary to have 2 interfaces per drive?
The setup is a Tape Area Network of 24 drives, which haven't been chosen
yet, attached to 2 McData 6064 directors which are then attached to the TSM
server and the LAN-free client servers. Any

It is possible to get a feel for how much needs to be migrated from a disk
pool to a tape pool by using a 'q stg' command.
Is there something that would give a similar number to know how much needs
to be put in a copy pool from either a
disk or tape pool? I was guessing some SQL query might
How about
backup stgpool srcpool tgtpool preview=y wait=y
Note that this can take a while to return results, depending on the size of
the environment.

Jack, you can do a backup stg primarypool copypool maxpr=1 preview=yes
wait=yes and it will give you that information.

Hi All,
Has anyone got TSM working together with the EMC Centera?
Did you manage to get it working with SET ARCHIVERETENTIONPROTECTION ON
and not clearing the database of backup/archive data?

The new TSM runing guide recommends using RAW volumes for performance
reasons. I have a client that doesn't want to go RAW because the JFS logging
goes away. I'm not that AIX savy to be able to argue one way or the other

Going RAW for performance, does that take away from

Hi Andy!
Thank you very much for your reply!
I checked the times when the clients encountered the Server detected system
error and I saw that the server reports a internal server error each time.
I checked all ANS1301E messages during the last backup window and I found
something strange. They are
I think the most interesting question is still unanswered: how much
performance do I gain with raw volumes? More exactly: how much less time
will an expiration take on a 100 GB TSM data base? I don't think raw volumes
would make sense for disk caches.
Does anyone have experience in this area?
We've changed our DR procedures to use RAW when we go to Sungard or IBM
Sterling Forest. For a 65GB database, this cut an hour off the recovery
time! First to create the filesystem and then to DSMFMT the volumes.
This is a dedicated TSM server on a p630 with SHARK disk. I don't think

As for the AIX perspective, we too converted everything TSM related, to

especially the ones that covered PERFORMANCE).

Hi Eric,
I would find it surprising if the two sessions in question were for two
different nodes. However, since the two sessions are for the same node, it
does not surprise me that a problem encountered on one session for a given
node could cause problems for other sessions for that same node.

I'll show my ignorance, but I didn't think TSM supported the Centera.
I thought access to the Centerra was via a specific API EMC has written
for it. To me, this implies that it would require a special program to

Relatively simple. The EST CAP is set when you define the DEVCLASS,
probably 80GB in this case (see line for tape 34). When data is then
writtent to the tape, the EST Cap is updated to the ACTUAL capacity
when the tape gets FULL. This may be higher or lower than the value

Hi Robert,
Its all down to how well the data is compressed by the drive
from your details I would say you have some medium sized databases which are
backed up and compressed, some zip files that are already compressed to the
limit and lots of text files in one place that can be compressed by

The numbers TSM reports are ALL from the server's point of view.
A filling tape will have a fixed (and pretty meaningless) EST CAP
determined by the device class until the tape gets marked FULL. Then TSM
changes EST CAP to the number of bytes actually written to the tape.

A non TSM related issue but please assist if possible...

Everything was going well until we stopped the cluster to update the

There are not any performance improvements when the TSM Recovery Log or

if the environment is all JFS. There may also be a need in the future to

Hi, Joni.
All of these questions are answerable via risk/benefit analysis and the
answers are all specific to your shop.
We have 2 separate SANs, and each drive plugs into both SANs. Each of our
highly available TSM servers has at least two interfaces with at least one
interface on each SAN, so

Moving from JFS to RAW (for DB and LOG vols) does in fact help performance
somewhat on larger systems. On smaller systems which are not
Bill,
JFS journalling doesn't journal data changes, only changes to metadata. So in a
filesystem with lots of file and directory creates and deletes its useful. In the TSM
situation, such changes are rare, and so JFS doesn't buy you a lot in terms of
recoverability.

No - you cannot do the SET ARCHIVERETENTIONPROTECTION ON command if you
have archive/backup data in the database. It MUST be cleared before the
command can be issued.
