What does your NLSPATH list? Should say something like this:

NLSPATH=/usr/lib/nls/msg/%L/%N:/usr/lib/nls/msg/%L/%N.cat

Then, next question:

Do you have a 'dsmclientV3.cat' file here:

/usr/lib/nls/msg/en_US/dsmclientV3.cat

or

/usr/tivoli/tsm/client/ba/bin/en_US/dsmclientV3.cat

?

If it's a 32 bit TSM 5.1 client, you may want to see if this package
is installed with:

# lslpp -l tivoli.tsm.client.ba.aix43.32bit.common
  Fileset                      Level  State      Description
