Monitoring Failover Recovery

Sean McMurray
I brought up two failover peers which went immediately into recovery.
They serve a pool of 6000 ips and have an mclt of 60. But they don't
seem to come out of recovery.
Is there a way to monitor recovery progress?

Re: Monitoring Failover Recovery

My secondary server comes out of recovery and recognizes that its peer
holds all free leases.
The primary server is stuck in recovery.

How can I see where and why it is stuck? What can I do to push it out of
recovery?

What do you mean that the secondary comes out of recovery? [How do you know this?]
The two servers should be in the same state - "communications interrupted" or "normal" [or some other state]

Are you saying that one server thinks communications is "normal" and the other doesn't. [By reading the logs...]

Since I'm not at all sure what the actual status of both servers [logs would be helpful] I can't really help you figure out what's going on.

Re: Monitoring Failover Recovery

The secondary server initally logs:

    failover peer partner: I move from recover to startup
    failover peer partnet: I move from startup to recover
    not responding (recovering)

but then switches to:

    peer holds all free leases

So it seems to have moved out of recovery, although there is no log message stating so.

The primary server initially logs:

    failover peer partner: I move from startup to recover

then:

    not responding (recovering)

and continues not responding forever.
