An unexpected error was encountered during a read operation that used the Read Multiple Count, Key, and Data or Read Track channel command. Normally, you need not take any action; however, see "Application Programmer Response".
The track is reread using other channel commands.
None.
If you get this message too many times in a job, then either the DASD ERP program that retries a temporary data check or DFSMSdss might be in error.
