Subsystem does not appear to belong to VNAC.
The storage area addressed by SSCTSUSE in the subsystem entry does not contain the VNAC eye catcher (VNCDSSCA) and is assumed to not be a VNAC subsystem. The utility will not process any subsystem it does not believe is a VNAC subsystem as this could lead to system failures or other errors.
Action: Check that the subsystem name specified on the JCL parm input to the program is correct and that the job ran on the correct system.
If the subsystem name is correct, take an SDUMP of ECSA and contact SDS Technical Support.
