AF/AA and PI Buffer Subsystem

We have multiple AF/AA systems (2017) with PI Buffer Manager version 1.2.4.1.

Is it possible to have analyses running on both servers to write data to the same tag?

 

In a normal operation, this may not be desirable, but, due to calculations changes, we have a need to recreate asset analytic derived values for many tags for an extended period of time.

To reduce the recreation time span, we'd like to be able to run backfills on multiple AF/AA systems for the same output tag for different time periods.

 

When I tried this, the analysis indicated it was creating values, the PI Buffer Manager showed the values being written, but they never showed up in the archive.

If I run the analysis from the primary AF/AA system for the same output, same time period, data appears in the archive.
