Hi Andreas, 

   I have a similar setup as of yours.  And we used tape copy storage pool to 
copy the data from primary storage pool.

   Can you brief what you are trying to do with "re-aggregation" in the copy 
storage pool. 

Regards,

Rajesh Lakshminarayanan

Hi all,

best wishes for the New Year! - And a question :-)

We have a DR500 - this is a IBM solution containing a pSeries, some FC storage 
and running AIX with a TSM/SSAM; but I think the same question would arise in a 
"normal" TSM.

Our DR550 is running SSAM 5.4:

tsm: DR550PP> q status
Storage Management Server for AIX-RS/6000 - Version 5, Release 4, Level 1.0

Data are fed into this DR550 via API from a CommonStore for SAP.

As I understand it, the CommonStore sends the data "one by one", so the data in 
the primary pool is not aggregated (verified by "select ... from contents").

I have defined a copy storage pool (devclass type FILE) and would like the data 
to be ("re-")aggregated in the the copy pool (there are many very small files 
and we ususally get only about 600 to 1000 MB into a 5 GB data file volume - as 
seen by "q vol").

Is this possible?
Any ideas?

Regards,

Andreas
