When using the DFSMSdss data mover for such CA Disk functions as BACKUPCC (Concurrent Copy) or when Sysparm USEDSSIO is specified, CA Disk will print out error messages in the same format as other CA Disk messages are issued.

However, if you want to view the error messages that DFSMSdss issues, specify a DD statement in your JCL labeled DSSMSGDD and you will be able to trace your job's DFSMSdss activity.
