DATA CONTROL INTERVAL WAS BEING SPLIT WHEN SYSTEM ABEND OCCURRED - DATA SET = (ddd), RELATIVE BYTE ADDRESS = (nnn)

Reason:

This message is issued when the CIDFBUSY flag is on in the control interval definition field (CIDF) of the data control interval of data set (ddd). This indicates that during prior processing of the cluster, an abend occurred while VSAM was in the process of splitting the control interval. This bit is turned on at the start of split processing and is turned off after the split has completed. Since this bit is still on, a system abend occurred before the split can be completed and therefore the integrity of the cluster may be lost. For more information regarding control interval splits, see the IBM publication OS/VS VSAM Options for Advanced Applications.

This message is for informational purposes only and causes no change in CADisk processing of the cluster. If no other error messages are issued for this cluster (message 2562 in particular), the data set is probably intact.
