Hi, Toni.
My TS7700 is under native VSE.
To delete virtual tapes, I first created via GUI a scratch category with 1 hour expiration time and "no hold", in may case, SCRATCH15 = X'00AF' (see "Appendix F. Library Manager volume categories" from redbook "IBM TS7700 Virtualization Engine with R3.2").
Then i execute under VSE these two commands.
LIBSERV SETVCAT,VOL=T00XXX,TGTCAT=SCRATCH15
LIBSERV SETVCAT,VOL=T00XXX,TGTCAT=EJECT
And virtual volume T00XXX gets deleted from the TS7700.
Best regards.
