Hi Rick,

I'm just about to write such a script ( moving data from a 3494 library to a 
SL8500 ). Can you send me a copy of it ?

Rich

When I moved our primary pools from 3494/3590's to 3584/3592's,  I used
movedata.
I found the movedat was much easier to control the process.  I coded a
script that would vary
the number of movedata's running concurrently depending upon the number of
free/available tape drives.  During the day It would run 3-4 movedata's.
while during
thenight I had 6-8 running. Our problem was the pools were very big
(several thousand
3494/3590 tapes), and we wanted to migrate the data asap.  If your pools
are not
very big, the it's probably not worth the effort to take control via
movedata's.

What would be the consequential differences between using migration
versus using 'move data' to transfer backup files from one primary
tape pool to another? I see that with 'move data' I would specify
volumes names myself, whereas migration would pick the volumes to
move. Are there other differences that would favor one technique over
the other? A difference in throughput rate would be especially
interesting.

The files are moving between data centers, and are now in virtual
volumes. The target tape pool consists of physical 3592 cartridges.

This is all running on RHEL 4, TSM 5.4.0.3, over a 10 Gb network link.

Thank you,
