What seems like not that long ago we ran our databases on JBOD disks (disks if
250m to 1gb). We setup oracle per design - logs on one disk, db files on
another, redo logs on another, archive logs on others (aix mirrored pairs).
Then indexes would pound it's disk, but other disk sat there not
Hello,
Does anyone have any idea if for TDP Exchange backups, one can include/exclude
based on LOG or Database file specifications. I'm looking for a way to tell
TSM not to dedup on LOG Files, but to process Database files only.
FYI, I've been running source-side dedup on exchange for
Hi Eric,
Besides the items you have highlighted so far (dsmc q opt, select * from
backups), what makes you think this file system is not being backed up? Are
there not TSM related logs (dsmsched.log) you could look at? Also, what
does the admin command q filespace kl1241m3 show you? I would think

on AIX more LUNs/hdisks is better. There are some resources allocated per
hdisk, where you want more. Set up 4 or 8 VG's for database. Growing database
filesystems is easier than adding more.

Hi David!
Nope, still not working...
tsm: AMSE2select * from backups where node_name='KL1241M3' and hl_name='/dev'
or hl_name='/DEV'
ANR2034E SELECT: No match found using this criteria.
ANS8001I Return code 11.
I guess I will have to open a PMR for it. Thanks for your help!

Each VG will be 2 or 4 LUNs from SVC.
I am not worried about the logs and storage pools. Only the DB.

The concurrency I'm aware of is at the hdisk/lun level. There's a
num_cmd_elems at on the fcs adapter which we set to 2k, and then queue_depth on
the hdisk. That's why spreading I/O across as many hdisks/luns as possible is
advantageous.

Same number of LUNs in fewer VGs, or fewer LUNs, too? The queuing concern
makes it sound like fewer LUNs. If so, as Rick says, that's also where your
I/O concurrency would suffer.
If it's the same number of LUNs, using one VG per LUN makes it easier to
isolate each LV to each PV rather than
Hi Stef!
Our Linux guys tell me that /dev is not a filesystem but a directory. That's
why it's not in the output from the mount command, nor in the output from the
df command.
The content is indeed dynamically build up during boot, but the TBMR manual
specifically states that it should be
Hi David!
We don't use the TSM scheduler, we use a third party scheduler. So every backup
is a new dsmc session which should pick up all dsm.sys changes.
It's a RedHat 6 server with the 7.1.2.0 TSM client installed.
Kind regards,

He claims there is a queuing issue with too many at the HBA. I guess I missed
that the last 12 years of being a storage/TSM admin.
I told him the theory of using many was to allow more concurrency. Before we
build I just want make sure this is not a mistake that cannot be easily fixed.
Hi, Sorry David I don't understand the VG's are cheap statement.
Your Volume groups are made up of 1 or more hdisks provided locally or from the
SAN.
I've split my VG's into 5 types of VGs
Dbvg - Databases
Logvg-Logs
Instvg -Instance
Bkvg- DB Backup
Stgvg - Disk storage
Andy is correct that in a select from the backups tables the '/dev' will be the
filespace_name and not the hl_name. But the '/dev' should show in the q
filespace.
Did you restart dsmcad and/or dsmc sched after updateing the dsm.sys file? Is
the dsm.sys in the default location or is it
VGs are cheap. Why does your AIX admin want to reduce the number of VGs?

I have an AIX admin that wants to build my new TSM server using two VGs for the
database (6 file systems) and one VG for the various logs.
We currently have 6 VGs for the DB and 3 VGs for the logs. Each VG contains 1
file system.
The DB is about 375GB and the new hardware is a P8.
No TSM
With your current vg setup you are dedicating one or more luns to each vg.
The good is dedicated resources of that lun (iops+capacity) in each vg.
But the converse is also true, you _only_ have the dedicated resources of that
lun in the vg.
If you max out the resources of a vg and others are
