Failover Agents: adding a “shared-hostname” failover pair where VIPs are in use

Hi Dojo,

I'm looking for info on new failover pairs to be added into an existing cluster - so found this page
https://docs.dataminer.services/dataminer/Administrator_guide/Failover/About_DMA_Failover.html

I understand it is not possible (at least not by default) to mix VIP & Hostnames to manage failover pairs - is that correct?

Should I add new FAILOVER pairs of DMAs where VIPs are in use, is there still a restriction for VIP that main & stand-by DMA need to be on the same /24 subnet?

Thanks

It is indeed not supported to mix VIP and hostname failover pairs in the same cluster.

The main & stand-by DMA don't need to be on a /24 subnet specifically, it can be anything from /29 and larger. Both agents need to be able to assign the same IP address to their network adapter (not at the same time) and be reachable on it throughout the rest of the network.
