For more information about the abend code, see z/OS MVS System Codes.
If modname is UNKNOWN and the storage location is a valid address, the name of the failing module is determined in the dump. DFSMShsm can intercept abend processing from other components. In that case, modname is UNKNOWN since it is not a valid DFSMShsm module. Often, this indicates a problem in the other component. Search problem reporting databases for a fix for the problem. If no fix exists, contact the IBM® Support Center. Please have the failing module name available when contacting the IBM Support Center.
For tasks other than ARCCTL, DFSMShsm processing continues. If the task is ARCCTL, DFSMShsm processing ends.
Notify the storage administrator.
The storage administrator should determine the effect of the abend on the data. If ARCCTL is the failing task, restart DFSMShsm. Notify the system programmer of recurrent abends.
