Data set dsname was being recycled from volume volser. While copying the data set, a DFSMShsm data set identifier was found within the migration copy or backup version where it was not expected. The migration copy or backup version may contain data that was not there when it was originally migrated or backed up. If the migration or backup tape is in single file format, bkid indicates the approximate block identifier at which the data set identifier was found. If asterisks appear, either the migration or backup tape is in multifile format or an error occurred when the NOTE macro was run to determine the current tape blockid. If an error occurred when the NOTE macro was run, message ARC0920I was written to the recycle log.
DFSMShsm processing continues. Recycle of the data set fails.
For a non-VSAM data set, the DFSMShsm data set identifier, *CDD**, is contained only within the common data descriptor record (CDD) of the first block of data. For a VSAM data set, the DFSMShsm data set identifier appears within the first block of data for the base cluster and within the first block of data for each alternate index.
If the data set legitimately contains the characters *CDD** at a position within the data block that corresponds to the position at which DFSMShsm places its own data set identifier, the message may be disregarded. Otherwise, the data set should be examined to see if changes to the data have been made since the data set was originally migrated or backed up. If the changes take the form of additional data at the end of the data set, the data may be recoverable by using the RECALL or RECOVER or RECYCLE command with the FORCE parameter. In addition, the recycle log should be examined for other instances of this message or message ARC0440I, which may indicate that additional data sets from the source tape have been altered.
