I currently have a Power7 production system and a Power6 HA system, running IBMi in single partitions.
The systems are configured for iASP mirroring using the Geographic Mirroring feature of PowerHA for i Enterprise Edition.
Currently I suspend the Geographic Mirroring for a few hours a night to perform a backup to tape on the Power6 HA system.
During this backup the Power7 production system remains available to production users, but mirroring is suspended to the HA system. Any changes to production data are queued up to be sent when mirroring is resumed. After the backup completes on the Power6 HA system, mirroring is resumed and mirror synchronization is achieved in about an hour or so.
I want to come up with a way to eliminate the “mirror synchronization time” and still have a point in time BU to tape of all our production data.
One idea I was thinking about was to come up with a way to perform a FLASH COPY of the remote mirror (the iASP attached to the Power6 HA system), without having to suspend mirroring from the Power7 production system.
My question to you is, is this even possible to do this using the PowerHA for i Enterprise Edition software on the IBMi? I imagine it would require sufficient disk and another active partition on the Power6 system… Any thoughts on this idea or any other ideas on how I could eliminate having to resynchronize the Geographic Mirror as part of my nightly BU process????
