DFSMShsm is in the process of performing an aggregate backup or aggregate recovery operation. Access Method Services (AMS) has been invoked to perform the function. During the process, AMS issues a message related to the function, and DFSMShsm intercepts the message for re-transmission to the ABARS activity log. This message is output if SETSYS ABARSACTLOGMSGLVL(FULL) had been issued, or if an error occurs during AMS processing.

• function is set to ABACKUP if issued during an aggregate backup operation.
• function is set to ARECOVER if issued during an aggregate recovery operation.
• amsmsgtext is the AMS SYSPRINT record. AMS messages have a prefix of IDC.
