Hi, Question about [ZMIRROR routine](https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=GHA_mirror_set_config#GHA_mirror_set_tunable_params_zmirror_routine). I analyze a problem with the label `NotifyBecomePrimary`. It seems not performed after a switch. After installing ZMIRROR routine in %SYS, is a restart required? If It's required, It could be explain my problem. Thank you.
