Re： Re: Failover question on the address pool

[Billy Ng]

Hi NHK,

I've tried it to modify the "local-state" value from omshell and found that the address state changed from "backup" to "free" after the MCLT value expired. Please correct me if I'm wrong. Thanks for your help.

Best Regards,
Billy

After(!) the partner is down, you do:

# omshell
> server <your server name>
> port 7912
> connect
obj: <null>
> new failover-state
obj: failover-state
> set name = "your cluster name"
obj: failover-state
name = "your cluster name"
> open
obj: failover-state
name = "your cluster name"
[...]
local-state = 00:00:00:02
[...]
> set local-state = 4
[...]
> update
[...]

You will see the changing server state in the log file, something like this:

Jan 29 09:36:11 dhcp0 dhcpd: [ID 702911 local6.info] peer cluster:
disconnected
Jan 29 09:36:11 dhcp0 dhcpd: [ID 702911 local6.info] failover peer
cluster: I move from normal to communications-interrupted
Jan 29 09:37:23 dhcp0 dhcpd: [ID 702911 local6.info] failover peer
cluster: I move from communications-interrupted to partner-down

(Most of) the corresponding information can be found in 'man dhcpd'.
