Hello.
 
TSM: 5.3.4.1 on AIX 5.3 TL5
TSM BA Client: 5.3.4.0 (also tried a new patch level)
TDP for MSSQL: 5.2.1.6
 
Having a very odd problem.
 
I have several TDP for MSSQL clients having a similar issue.  A backup starts 
at the scheduled hour.  All files that are <MAXSIZE backup fine.  If a file 
that is >MAXSIZE is found, on the client we see a "Waiting for Tape Mount" 
message in the log file.  On the server we see a tape mounted, however the 
client never proceed and the backup hangs.  We've let a backup sit until the 
session times-out and beyond to no avail.  To complicate this further, we took 
TDP out of the equation and created a MSSQL dump backup.  When we try to backup 
the dump using the regular TSM BA client, we get the same result.  
 
We thought network, however while the client is hung if we open an ftp session 
to the TSM server and do a dd transfer of ~3GB, no problems.
 
This is happening only on some nodes.  Others are fine.
 
Has anyone else seen this?  And, if so what was the resolution?
 
TIA
