Guys,
  We had a TSM server and TSM Storage Agent combination of V5.1.1.0.  The TSM 
client on the AIX server is at V5.1.7.0.  This AIX server is running DB2.  We 
have a Windows 2003 TSM server and a 3494 tape library with two Fibre attached 
3590 drives.
   
  Anyway the OS backup on this server has 120 GB and was backing up in 54 
minutes. The DB2 backup on the server had never been configured to run LANFree 
(don't know why) but backed up 60 GB in 1 hour and 45 minutes over the LAN 
(10/100 NIC).
   
  We upgrade the TSM server to V5.3.3.3 which went without any issues.  We then 
upgraded the TSM storage agent to V5.3.3.0 (they like to not put any patches on 
this very important AIX DB2 server unless it is absolutly necessary). According 
to the doc you can use a V5.3.3.0 storage agent with a V5.3.3.3 TSM server 
without any problems.
   
  Now the storage agent backup of the OS runs in 4 hours and 30 minutes. Yes, 
we are absolutly sure it is still going LANFree. We can see this when we route 
the "q sess" command to the storage agent. We also so that the LANFree bytes 
transferred shows that the whole 120 GB is going LANFree.
   
  We did put "ENABLELANFREE YES" in the dsm.sys that the DB2 agent was in. The 
DB backup is not completing in 1 hour and 15 minutes.  We would like it to be 
faster but it is faster than when it ran over the LAN so people are happy with 
it.
   
  After this upgrade we gained 30 minutes on the DB2 backup but we lost 3 hours 
and 30 minutes on the OS backup.
   
  The dsm.sys files were setup to use lanfreecommmethod of TCPIP. That was good 
with V5.1.1.0. However, seeing that the client and storage agent are on the 
same server I changed the method to SharedMem to see how much of a difference 
that makes.
   
  So after that book, has anyone else experienced a slow down in Storage Agent 
speed after an upgrade. I've went through many and this is a first for me.
   
  Oh, no errors of any kind in any of the logs.
