We have DFM and HUM on servers seperate from LMS and configure as DCR slaves.
Recently maintenance occured on the LMS, box and the DFM and HUM systems deleted devices from their local DCRs.
Then we had to take HUM and DFM out of DCR slave mode, put them back in and redo the whole DCR, DFM device import and HUM poller definitions.
I suspect there is nothing we can do to prevent this from happening ? if there is please let me know.
My understanding is that a Slave DCR will only delete devices from its local DCR when it knows for sure the devices are no longer in the Master DCR.
Say a master DCR system is down for a day. Can someone confirm that a slave DCR will not automatically delete devices after a period of a few hours if the Master DCR system is down ?
