Cross-node TSM restore is all about restoring a database TSM backups from some other server on to another server while accessing TSM directly from the new server. If you don't want to deal with all this you can extract the files locally and copy them over to other server.
On your original instance open and check the contents of the following file "/usr/tivoli/tsm/client/api/bin64/dsm.sys" and list your TSM node names
After identifying the node name grant appropriate previlages to the user that you will mostly like use for db restore/recover purposes.
Assuming your node name is "db2inst2x-db2", your instance name owner name is "xyzp01" and your dbname is "DB001P01" - following are are the sample commands
db2adutl revoke user xyzp01 on nodename db2inst2x for db DB001P01
db2adutl grant user xyzp01 on nodename db2inst2x-db2 for db DB001P01
db2adutl query db DB001P01 nodename db21p1x-db2 owner xyzp01
db2 restore db DB001P01 use tsm options "'-fromnode=db21p1x-db2 -fromowner=xyzp01'" TAKEN AT 20101112080432 INTO DB001P01 REDIRECT
