To specify whether CA VM:Backup remounts tapes already written to in the currently running backup job, use the Remounts field. The following options are available in the Remounts field:
Allows CA VM:Backup to remount tapes, thus minimizing the number of tapes that are needed for the backup job. This option is the default.
Prevents CA VM:Backup from remounting tapes in most situations. This option can make backup jobs run more quickly.
If your data center uses automatic cartridge loaders (ACLs), you may want to select this option. Depending on the control setting for your ACL, it may not be able to remount a tape that has already been mounted in the currently running job. This is true if the control setting on the ACL is set to AUTOMATIC. This may also be true if the control setting is set to SYSTEM and the software you use to mount tapes cannot handle this situation.
Note: For more information about tape remounts, see the "Tape Remounts" section in the chapter "Managing Tape and DASD Resources" in the System Programmer Reference Guide.
