I have set COPYPOOLNAMES in primary pool to have the both primary and copy 
files during export/import for nodes and then I hit problem with TDPO backups. 
RMAN is sending data to TDPO --> TDPO is sending data to TSM Client --> TSM 
Client is sending data to TSM Server --> TSM Server is failing. I do not think 
RMAN can see something on TSM Server. This is TSM problem.

RMAN-03009: failure of backup command on t1 channel at 04/07/2013 15:03:42
ORA-19502: write error on file "/LPAR01/vcen.07.0.1228.1.812127807", block

ORA-19511: Error received from media manager layer, error text:
ANS1315W (RC15)   Unexpected retry request. The server found an error while 
writing the data.

>>>Why do not make a separate job to copy the data from primary to copy pool?
It is a good question. According to setup decision to propagate files to copy 
pool is made by client site (export/import, TSM agent, etc).
I was running all copies by separate schedules for many years. Now I am not 
sure what is better write data in parallel to primary and copy pools during 
backup or write to primary pools and then propagate data to copy pools.
It is possible because I am using Data Domain VTL for primary pools replicated 
to disaster site and FILE copy pools.  I understand all possible problems with 
performance, but at the same time I prefer to save time as well.
