I've seen there is an options to auto-update the hostPrimaryAddress of an OSSV host.
I suppose this is the solution for ip dynamically changed by dhcp .. (this is my situation).
Action to take when the primary IP address of an OSSV in DataFabric Managerâs database is different from the IP address given by theDNS. The options are off, warn, error, update
If the option is off, check for IP address mis-match. If the option is warn, check for IP address mis-match and give a warning if the address do not match. If the option is error, give an error if the IP address do not match. If the option is update, update the hostPrimaryAddress if it is different from the IP address that we get from the DNS.
