Use the TAPECHAIN record to specify whether CA VM:Backup is to write tape chaining information in the trailer labels of tapes it uses in backup and MPC jobs. For more information, see Tape Chaining.
TAPECHAIN [YES | NO]
If you disable tape chaining in tape labels, only physical tapes are affected; DASDtapes are not.
Important! CA VM:Backup must be interfaced with CA VM:Tape to specify TAPECHAIN NO. If tape chaining information is not found in the trailer labels of tapes, CA VM:Backup uses tape chaining information in the CA VM:Tape TMC. If CA VM:Tape is not available, restore and MPC jobs can have unpredictable results.
Specifies whether CA VM:Backup is to write tape chaining information in tape labels.
You can include only one TAPECHAIN record in the VMBACKUP CONFIG file. The default is TAPECHAIN YES.
Interactive Reconfiguration
You cannot interactively reconfigure the TAPECHAIN record through CA VM:Backup system administrator screens.
