I've started reviewing their environment and see some issues. My first question is, the HA Interconnects, do c0a and c0b interfaces need to be configured with their partner interface as shared? Also, should c0a and c0b be configured on different subnets or the same? And do they need to be configured in the /etc/rc files also?
