An ADDVOL, BACKVOL, or FRBACKUP command has been issued specifying a dump class class that is not defined to DFSMShsm.
During ADDVOL processing for a primary volume, if the AUTODUMP (class,...) subparameter is not specified, the MCV record is checked for dump classes specified on a previous ADDVOL command. Similarly, during ADDVOL processing for a dump volume, if the DUMPCLASS(class) subparameter is not specified, the DVL record is checked for a dump class specified on a previous ADDVOL command. If a dump class specified on a previous ADDVOL command no longer has a BCDS record describing it, this message is issued and the ADDVOL command fails.
During BACKVOL, either specified dump class class is not defined, all the specified dump classes are disabled, or the dump classes specified on the command contain conflicting encryption/HWCOMPRESS settings.
During FRBACKUP, required dump class class is not defined.
The command fails. DFSMShsm processing continues.
If the dump classes contain conflicting settings, modify the dump class definitions so that the encryption/HWCOMPRESS settings are identical for the volume or storage group, or remove the conflicting dump classes and create the dumps separately. If the command failed for a reason other than the conflicting dump class settings, reissue the command with the proper dump class name or names. Any preceding ARC0650I message for the same volume indicates the invalid dump class names.
