Increased Capacity
PowerHA previously had a limit of 45,000 resources that could be monitored by the administrative domain. However, environments continue to increase in size, and very large environments with more than 45,000 resources may require additional independent solutions to manage the additional level of resources, which increases the complexity of managing the entire environment. With 7.4 PowerHA 4.0.1, the administrative domain's monitored resource entry limit has increased by over 340% to support up to 200,000 monitored resource entries, enabling support for the largest environments.

Additional Administrative Domain Enhancements
Support for replicating encrypted passwords set with the QSYSUPWD API. Previously, the use of the QSYSUPWD API caused the user-affected profile to be marked as inconsistent within the administrative domain.
Simplified implementation by eliminating the need to change user profile passwords after changing the value of the QRETSVRSEC system value from 0 to 1.

Tip: This improvement of eliminating the need to change user profile passwords after changing the value of QRETSVRSEC is also available in PowerHA for IBM i 7.2 (SF99776 level 13) and PowerHA for IBM i 7.3 (SF99876 level 10) |
Improved control over changing the synchronization option for an administrative domain using the CHGCAD command. Previously, all nodes in the administrative domain had to be active in the cluster to change the synchronization option. The synchronization option can now be changed even when some nodes in the administrative domain are inactive. When combined with the source node parameter on the STRCAD command, this gives full control over how monitored resources are synchronized throughout the administrative domain, both when starting the administrative domain and when starting cluster nodes.
The WRKCADMRE command has been enhanced to work even when clustering is inactive. With this function, users can view monitored resources within an administrative domain on a local node even during maintenance windows.
