Hi Gordon,

You can do this using omshell. Here's the interactive version, it's
easy enough to put this in a shell script.

omshell
> server <hostname>   
> port 7911
> key <keyname> <secret> 
> connect
obj: <null>
> new failover-state
obj: failover-state
> set name = "<failovername>"
obj: failover-state
name = "foo"
> open
...
partner-state = 00:00:00:02
local-state = 00:00:00:02
...

The failover states are defined in includes/failover.h, 2 = normal.

/* A failover peer. */
enum failover_state {
        unknown_state,
        partner_down,
        normal,
        communications_interrupted,
        resolution_interrupted,
        potential_conflict,
        recover,
        recover_done,
        shut_down,
        paused,
        startup,
        recover_wait
};


You also need to enable omapi in dhcpd.conf. See dhcpd.conf man page
for details on creating secrets.

# OMAPI
omapi-port 7911;
key <keyname> {
  algorithm hmac-md5;
  secret <secret>
}
omapi-key <keynmae>;
