z/OS DFSMSdss Storage Administration
SC23-6868-01

DFSMSdss recognizes three different formats for a VTOC index:
  • SYS1.VTOCIX.Vvolser
  • SYS1.VTOCIX.volser
  • SYS1.VTOCIX.Volser.
If the first character of a VOLSER is numeric, DFSMSdss renames it (or prefixes it) so that the VOLSER begins with the letter "V." For example:
  • If a VOLSER is 12345, DFSMSdss renames it to V12345
  • If a VOLSER is 123456, DFSMSdss renames it to V23456.
