What is the indication that it is not compressing? Is it the same data as t=
he test system?

Although the spec is the same, do any of the netbackup logs show why compre=
ssion may not be running?

Tape Library: IBM 3584 partitioned into production and test environment

Operating System:  Solaris 9, Windows 2003, HP-UX 11i

Netbackup: 5.1 mp3

=20

Just upgraded from STK L700E LTO-1 library to a IBM 3584 LTO-2 library

All of a sudden tape compression is not working on any flavor media server,=
 but only in production. Our test environment is compressing data at a hard=
ware level just fine.  Same OS, same NBU release, same Tape library, same t=
ape drive drivers, same HBA cards, same firmware, same st.conf file on the =
Sun systems.


Can anyone think of what we might be missing that would cause the productio=
n environment not to be using hardware compression while the test environme=
nt is?
