It's been too long since I've installed a module (APM, NPM) on our Orion v9.1 systems and I can't remember if I'm supposed to install a module like IPAM v1.0 on our Hot-Standby system in addition to the primary NPM node. From the looks of it, our former admin did additionally install APM and NPM on the Hot-Standby... but know I don't know (rather, can't remember) if that was necessary.
Thanks in advance.
