Hi Chris,
     All options are documented in the man pages.
Which can be accessed from the command line in case of linux and also from
The web-ui of Ops-Mgr.
ContorlCenter->Help-General Help and Man pages.
For your convinence I am pasting the same below.
processHostPrimaryAddress: Action to take when the Primary IP
          address of the storage system in DataFabric Managerâs database is
           different from the IP address given by the DNS. The options are
           off, warn, error
           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.
           The default value of the option is warn.
