FORMAT-1 DSCB NOT FOUND FOR DATA COMPONENT (ddd) ON VOLUME (vvv) - IT IS ASSOCIATED WITH CLUSTER (ccc). A DEFAULT LAST USE DATE OF 2155.366 WAS USED

Reason:

A selection criterion of USEDT was specified on a SELECT or EXCLUDE command, causing CADisk to attempt to retrieve a format-1 DSCB for the data component of cluster (ddd). This is where the last use date is stored for clusters defined in an ICF catalog. However, a format-1 DSCB cannot be found for the data component on volume (vvv). The data component is associated with base cluster (ccc). This can be caused by one of the following conditions:

• The cluster is defined in a user catalog and is suballocated. If the catalog named on the SCAN CATALOG= command is not an ICF catalog, the USEDT reference is invalid (last use date is not supported in VSAM user catalogs).
• The volume information for the cluster found in the ICF catalog is incorrect.

When this condition is encountered, a last use date of 2155.366, is assumed for the cluster. This will prevent the cluster from being archived based on an invalid last use date.
