MERGE abend U1547 after Disk maintenance upgrade
The abend U1547 after a CA Disk maintenance upgrade is caused by a mismatch between the PARMEDIT member in the CCUWPARM and the load library CCUWLOAD. A PTF has introduced a new Sysparm or changed an existing Sysparm in CCUWPARM member PARMEDIT, but the new member is not taken over together with the new CCUWLOAD.
Release: SMDI3900200-12.5-Disk-Backup and Restore-for z/OS
Take over the new delivered PARMEDIT member into your active CCUWPARM.
