RACF protection of tapes used for stacking

You can use RACF® protection for tapes with stacked aggregate backup files. In these examples volser is the serial number of the stacked tape's volume.

• If you are using a new tape to stack aggregates, use these commands to protect it with RACF:

  SETSYS TAPESECURITY(RACF)
  RDEFINE TAPEVOL HSMABR
  RALTER TAPEVOL HSMABR ADDVOL(volser))

• If you are using a tape with existing ABACKUP version to stack additional aggregates, use the these commands to protect them with RACF:

  SETSYS TAPESECURITY(RACF)
  RDEFINE TAPEVOL HSMABR
