[ADSM-L] lots of image backups

Hello all,

I am facing a challenge:

I have a situation where I must take backups (image backups) of some 4000 raw 
LVs on AIX. These LVs are mounted FlashCopy volumes, so I don have to worry 
about snapshots and so on.
They were being backed up to a disk storage pool (!) with a MAXSIZE of 900MB, 
so the LVs smaller than this size would goto disk, and the others to tape.
I am trying to reduce the disk usage, so I thought: let's send all of this to 
tape. I reused the exiting shells which:
1. split the LV list in 20 LVs chunks (one file per 20 LVs)
2. Spawns up to 8 dsmc processes at a time with command lines as: dsmc backup 
image `cat <20 LV list filename>`

I noticed, though, that for each of the LVs in the file, a new session gets 
opened on the server. Result: much slower backup than before.

Is there some way to make the client backup all the 20 LV images in one 
session? Any other thoughts?

More info:

TSM Server 5.5.1 on AIX 5.3 ML6
TSM client 5.5.1.
Client and server are on the same machine, that gets the FlashCopy LVs mounted
COMMMETHOD is TCPIP

Thanks in advance,
