DFSMShsm has taken a data control block exit because a read error has occurred in reading the VSAM data set backup version being recovered or the migration copy being recalled. Message ARC1001I gives the data set name.
The reason code displayed in the ARC1001I message could either be the return code from an internal DFSMShsm call to IDCAMS or a DFSMShsm reason code. The IDCAMS return codes are 4, 8, 12 and 16. For an explanation of these return codes, see z/OS DFSMS Macro Instructions for Data Sets. A reason code of 0 indicates that an I/O error has occurred. A reason code of 2 indicates that an invalid data or record length has been encountered.
Recovery or recall of the data set ends. DFSMShsm processing continues.
For reason codes 4, 8, 12, and 16, respond to the associated access method or hardware error message if available. For all reason codes, the input data set may be unusable and would have to be replaced with a backup copy.
