AHL153I
UNABLE TO OBTAIN SENSE INFORMATION ON AN END-OF-SENSE I/O INTERRUPT

Explanation

The generalized trace facility (GTF) cannot trace the sense information because of one of the following:
  • The address of the sense bytes is zero.
  • CSW-8 (channel status word) does not point to a sense channel command word (CCW).

System action

GTF issues this message to the GTF output data set as a trace record.

GTF traces the CCW and writes the input/output supervisor block (IOSB) to the GTF output data set. If an error recovery program (ERP) is present, GTF writes it to the GTF output data set. GTF continues processing, but ends this channel program trace.

System programmer response

Obtain the SYSOUT output for the job. Search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM® Support Center.
