Should have mentioned: we upgraded to AIX 6.1 TL 7.1 at the same time as the 
upgrade to TSM server 6.2.3.1.  
We upgraded to AIX 6.1 TL 7.0 on Jan 12th, and of eleven database backups 
before adding the 7.1 patches, two were exceptionally long - unprecedentedly 
long at that time, between 5 and 6 hours.
We're up to one long database backup out of the last six now, since resetting 
REORGDURATION and making sure DB backup is not during the reorg window.

Subject: [ADSM-L] Slow TSM DB Backup

Hi.........

We are experiencing slow TSM DB backup process on both of our TSM systems using 
AIX V6.1.7.x, TSM V6.2.3.100, Atape v12.4.1.0.  The issues began immediately 
after we upgraded from AIX v5.3.12.3 to AIX v6.1.7.x. We have created a 
performance PMR#53387,379,000 with TSM support.  With 100GB data in a DB2 
database, we are seeing 30 to 60sec waits between .1/.2GB database transfers to 
IBM LTO4 tape drives via TSM q se screen. It is taking a very long time to 
complete a TSM DB backup. Before the AIX upgrade, the full DB backup took about 
10 minutes; now we are seeing backups of hours in length.

Anybody having these types of issues??
