CM and MA DataProtector 6.0 on SLES 9.0 and MSL2024

[Alex Karpovski]

Hi,
I'm sure I do not have compression on LTO-3 drive at all. DP write no more then 380GB on one 400/800GB tape. It can be like 330GB or even 300GB and then jumps to another tape.
my tape dive is /dev/nst0 and I already tried to use /dev/nst0a or /dev/nst0l it simply hangs DP.

My question is: how to make compression works?
I got all available patches installed.

Thank you, Alex.
