tpautoconf -t did not show drives detected gives error

I am working on tpautoconf -t one of Linux server but it shows following error :

tpautoconf -t
/usr/openv/netbackup/bin/bpclntcmd: error while loading shared libraries: libnbclientST.so: cannot open shared object file: No such file or directory

I am not sure what kind of error is there is communication between client/Media/Master server look good.

I suspect that is there any patch updation or Library Licences Keys need to be update ?

Currently it is running Netbackup 7.1

Please sugest.
