Hi everybody,
I have another question, today the database don't backup on a scratch tape
because failure to excessive write error.
The tape use is still in scratch and i don't want to reuse this tape the
tapedriver was not near and i don't do a checkout volume and take this tape so
i'am trying

Hi Wanda,
I'm using Deduplication and have found that tsm life would be much easier if
the stg pool was kept smaller under 3TB in size. I haven't done enough testing
with this, and I know it is slightly counterproductive to achieve the highest
deduplication savings. But it sure does make the

An experiment last night leads me to believe (N=1) that a renamed VM will take
a full backup even if you rename its filespace to match its new VM name.

In trying to troubleshoot an unrelated performance PMR, IBM provided me
with an e-fix for the dedupdel bottleneck that it sounds like you're
experiencing. They obviously will want to do their due-diligence on
whether or not this efix will help solve your problems, but it has proved

Hi, W !
Always nice to hear from an old friend.
I needed to dig deeper in the guide. I was looking under ALMS and Virtual
IO for a setting to change. I should have been in Logical Libraries.
Got it.
Thanks for the nudge.

Woo hoo!
That's great news.
Will open a ticket and escalate.
Also looking at client-side dedup, but I have to do some architectural
planning, as all the data is coming from one client, the TSM VE data mover,
which is a vm.
Re client-side dedup, do you know if there is any cooperation

Client-side dedup and simultaneous-write to a copy pool are mutually
exclusive. You can't do both, which is the only theoretical way to
enforce deduprequiresbackup with client-side dedup. I suppose IBM could
enhance TSM to do a simultaneous-like operation with client-side dedup,
but that's not
I can second that Sergio,
Backup stgpools to copy tapes is not pretty, and is an intensive process to
rehydrate all that data.
The one extra thing I did was split the database across multiple folder for
parallel I/O to the Database. That has worked out very well, and I currently
have it
While we don't do deduplication (tests show we gain less than 25% from it),
we also split our DB2 instances across multiple, physically-separate
volumes. The one thing to note is that you have to dump and restore the
database to spread existing data across those directories if you add them
Hi All,
Is someone using this script for reporting purpose ?

Is anyone doing stgpool backups to a dedup file copy pool?

Hi Skylar !
Yes that would be the easy way do it, there is an option to rebalance
the I/O after you add the new file systems to the database. I had already setup
TSM before the performance tuning guideline was released. Doing this way, will
require more storage initially and running
Hi Wanda,
some quick rambling thoughts about dereferenced chunk cleanup.
Do you know about the 'show banner' command? If IBM sends you an e-fix, this
will tell you what it is fixing.
