I run the following command to perform an online backup to tivoli
storage manager for DB2 UDB 7.2 on AIX 5.2L and it keeps failing with the error message:

db2 backup database prod online use tsm

SQL2062N An error occurred while accessing media
/home/db2inst1/sqllib/adsm/libtadsm.a Reason Code "406"

Any way to fix this error so that I can backup our database? Thanks

Scott

Reason code 406 returned by TSM
Explanation: The options file specified by file-name
cannot be found.
System Action: The TSM client ends.
User Response: See if you have the environment
variable DSM_CONFIG (or DSMI_CONFIG for the API)
set, which explicitly identifies the TSM options file. (
You can do this by entering the SET command at your
system.) If this environment variable is set, ensure the
file indicated by the variable exists. If it is not set, then
TSM looks for the file dsm.opt in the current directory.
If neither of these cases is met, you receive this error
message.
