EDG6130E

Explanation
The end of volume has been reached during backup
to tape. Either, an additional tape volume is required while the control
data set backup is directed to tape without using concurrent copy,
or an additional tape volume is required while the journal backup
is directed to tape and control data set updates are being made.
In
both cases, DFSMSrmm supports only one tape volume. This is a documented
restriction of DFSMSrmm.

System action
Backup processing stops. DFSMSrmm sets return
code 12.

Operator response
None.

System programmer response
To correct the problem you have the
following options: Use BACKUP(DSS) with concurrent copy.
Direct the backup output to DASD.
Use a tape volume with higher capacity
