Hi All,

Need a support to resolve below error:

BACKGROUND completed with completion state SUCCESS at
15:58:27. (SESSION: 396129, PROCESS: 1814)

Due to Fragmentation issue, Backup copy pool, Move data are getting effected. PMR suggested to upgrade TSM to 7.1.7.0 to 7.1.7.1, which was performed 2 weeks back, but still same issue.

Now need a support to fix this. Please help.

Just did a quick google of the warning message, ANR3247W and there are several ways that could happen with a few solutions.
Also, should go IBM to ask for "support to fix this" probably.

Hallo Rajatsm

I think, that MARCLANT is absolutely right: - you have to insist and follow-up on that PMR.

Additional Remarks:

The two following SWg - Support Infos

1.) http://www-01.ibm.com/support/docview.wss?uid=swg1IT13236 and
2.) http://www-01.ibm.com/support/docview.wss?uid=swg1IT03650

describe also "pending fragments" related issues which should have been fixed.........but.........

There exist also an undocumented option for the FRAGMENT SIZE:

if you do a q node xxx f=d you will see the value "SPLITLARGEObjects yes".
This is related to the FRAGMENT SIZE a node can have.

There is an undocumented option: MAXFRAGMENTSIZE which describe and can influence the value:

q opt MAXFRAGMENTSIZE (with SETOPT you can change this value)

May be you can ask IBM, if it makes sense to reduce this value...

Not a final solution, but that's all what comes into my mind...
