PowerHA continues to deliver additional enhancements including:

• A new modern web-based interface for monitoring PowerHA environments

• Enhanced administrative domain integration with support for synchronizing user auditing (CHGUSRAUD) and maximum sign-on attempts (MAXSIGN) profile attributes for user profiles across the environment

• IBM FlashSystem and Spectrum Virtualize FlashCopy enhancements, including additional automation and simplification of IASP-based FlashCopy

New Modern Web-Based Interface

PowerHA has always required minimal ongoing monitoring and management. Previously, most monitoring and management for PowerHA was done either through the green screen command-line interface, SQL services, or through the PowerHA web interface built into the heritage Navigator for i.

This update provides the first installment of a new modern web interface for PowerHA, giving at-a-glance health information and allowing easy management of PowerHA operations from a web browser.

The web interface is configured automatically with the following settings:

• Run on non-secure HTTP port 2098

• Automatically start when the *HTTP server is started

For additional information, including how to enable secure HTTPS, see: Configuring the PowerHA Web Interface

Enhanced Administrative Domain Integration

The administrative domain in PowerHA synchronizes security and configuration-related objects across a PowerHA environment, including user profiles, so that changes to resources monitored by the administrative domain are automatically synchronized with the other nodes.

With this enhancement, PowerHA now supports synchronizing additional attributes on user profiles, including the following:

• Synchronization of user auditing (CHGUSRAUD), including the object auditing value (OBJAUD) and user action auditing (AUDLVL) attributes.

• Support for synchronizing the new user-level maximum sign-on attempts (MAXSIGN) attribute on user profiles.

Existing monitored resources in the administrative domain that previously monitored all attributes for user profiles will automatically begin monitoring the new attributes after all nodes are updated to a PowerHA version supporting the new attributes.

Integrated FlashCopy Automation Enhancements

Previously, PowerHA introduced automation for IBM FlashSystems and Spectrum Virtualize IASP-based FlashCopy, reducing the need for customized scripts or external tools. This update provides additional automation, including:

• The ability to run a user exit program as part of FlashCopy operations.

• Simplified management with the ability to suspend and resume FlashCopy sessions.

Ability to Run User Exit Program for FlashCopy

The Start SVC Session (STRSVCSSN) command has a new target exit program parameter that submits an exit program after the target ASP action is completed.

Simplified Management of FlashCopy with the Ability to Suspend/Resume FlashCopy

Previously a FlashCopy operation in PowerHA required a process similar to the following:

1. Start a PowerHA session to take a FlashCopy, specifying the configuration information for the FlashCopy.

2. Ending the PowerHA session when done with it.

3. Repeat the process regularly.

While PowerHA provided incremental FlashCopy as an option for some users, an incremental FlashCopy can use significantly more storage than a thin-provisioned FlashCopy. With this enhancement, PowerHA now provides the ability to suspend and resume a FlashCopy in instances where repeated FlashCopy operations are desired, which has the following benefits:

• Configuration information is specified only once, when initially starting the FlashCopy session, reducing the potential for errors.

• Reduced the time for FlashCopy operations by keeping some configuration information in place for the next FlashCopy.

• Reduce the chances of requiring manual cleanup on the external storage device.

Once done with a FlashCopy use the CHGSVCSSN with option *SUSPEND on the FlashCopy session:

CHGSVCSSN SSN(MYFLASH) OPTION(*SUSPEND)

When ready to take a new FlashCopy, use the CHGSVCSSN with option *RESUME on the FlashCopy session:

CHGSVCSSN SSN(MYFLASH) OPTION(*RESUME)
