ESNPI83E
GROUP PROCESSING: COPYVOLID(YES) REQUIRED
Cause
COPYVOLID(NO) was specified with GROUP processing. When the POSTSNAP does not occur in the same execution as the PRESNAP, the original volser for the target device cannot be remembered in order to restore it after the device has been activated.
Action
Specify COPYVOLID(YES) and rerun.

ESNP0V0E
NAME PARAMETER REQUIRED, MISSING
Cause
The required NAME parameter has not been specified.
Action
Specify the NAME parameter and retry.
