DHCP Failover not working

[Ryan McCain]

I am attempting to get DHCP failover working between a SLES 9 s390 box
running dhcp-server-3.0.1rc13-28.18 and a SLES 10 s390x box running
dhcp-server-3.0.3-23.5.

The primary is the SLES 9 box.

I start both of them and both output this to the logs:

failover peer failover: I move from recover to startup
failover peer failover: I move from startup to recover

Is that right?


Also, when stop dhcpd on the primary server, the secondary server logs
this:

Dec  6 16:41:31 dss-ml93la10 dhcpd: failover: listener: no matching
state

and never takes over handling dhcp requests.

below are sniplets from the dhcpd.conf files for the primary and
secondary servers, respectively.
