Peter, RTFM reveals the following. (This is from z/OS 3.1 MVS System Messages Volume 6 (GOS - IEA) SA38-0673-60)
RETURN CODE 86 Explanation: Recatalog error. Reason Code Description 6 Explanation: Either the primary VSAM volume record (VVR) points to another catalog, or the primary VVR or non-VSAM volume record (NVR) for the object being recataloged was not found on the first volume serial number specified. The primary VVR or NVR contains the data set information needed to recatalog the object. Possible causes of this error are: • No VVR exists. • A VVR exists, but it points to another catalog. • Parameters were not specified as they were when the cluster was originally defined. The parameters are NAME, INDEXED, LINEAR, NONINDEXED, NUMBERED, and VOLUMES. Programmer Response: If no VVR exists, then re-issue the DEFINE command, without the RECATALOG parameter, for the ICF catalog. If the VVR exists but points to a different catalog, specify the correct catalog and re-issue the DEFINE command with the RECATALOG parameter. If the original values for parameters NAME, INDEXED, LINEAR, NONINDEXED, NUMBERED, and VOLUMES were not specified, specify the original values and re-issue the DEFINE command with the RECATALOG parameter. Return code 86 is also described here although you have to scroll down quite a way to get to 86. https://www.ibm.com/docs/en/zos/3.1.0?topic=messages-idc3009i There are quite a few scenarios there for a Reason code 6. You will have to consider each one.
