If the HSM_MSGDS_HLQ subsystem parameter is set to the same high-level qualifier that is specified in the MESSAGEDATASET parameter of the HSM SETSYS command, the SYSPRINT data set contains diagnostic messages that are generated by HSM and DFDSS. The HSM messages are bracketed by the DSNU421I and DSNU422I messages. The name of the HSM message is displayed in the utility SYSPRINT.
