What TSM Client file sets for VSS Requestor feature?

[teeraw]

I used TSM client on AIX and found issue "VSS Requestor" installed by no license.
But I'm not sure what filesets to uninstall. My TSM client's fileset are like these:

tivoli.tsm.client.api.64bit
tivoli.tsm.client.ba.64bit.base
tivoli.tsm.client.ba.64bit.common
tivoli.tsm.client.ba.64bit.hdw
tivoli.tsm.client.ba.64bit.image
tivoli.tsm.client.ba.64bit.nas
tivoli.tsm.client.ba.64bit.snphdw
tivoli.tsm.client.ba.64bit.web
tivoli.tsm.client.jbb.64bit
