For automated takeover systems, especially critical ones (tho you can
argue that any system setup with automatic takeover is critical by
definition), you should have multiple heartbeat paths. Ethernet, serial
cable, on shared disk, fibre or whatnot.
Having false takeovers due to missed heartbeat on one set of ethernet
cards could also likely be missed on another set of cards, even with a
Maybe you should investigate alternate paths?
