DUPLICATE CONTROL FILE SPECIFIED

Reason:

A duplicate control file was found in the DDNAMES MIM file. MVS formatted control files are considered duplicates if the data set name and VOLSER are identical on both files. CMS or CMSFP files are identical if the control unit address and LABEL fields are identical on both.

CA MIM for z/VM ignores the indicated DDNAMES MIM entry and continues initialization. When using CMS-formatted control files, only one control file can be allocated to each minidisk. When using MVS-formatted control files, each control file must be allocated a data set.

Action:

Remove the duplicate control file from the DDNAMES MIM file and restart CA MIM for z/VM.
