Second VPN cluster unreachable.

[dtlam76_]

We are currently running an SA 4000 box ver 6.0 r3.1 which is clustered in an active passive configuraton.

At the moment 1 cluster is unreachable and the other is up and running with no issues. I can't for the life of me figure out how to get the downed cluster to come back up. 

I've checked both configurations and they are identical any ideas?

Are you truly talking about a second cluster, or do you mean the second member of the cluster?

I have two SA4000 FIPS units in a cluster in an active/passive config. They normally both show green in the Status page.

I have noted that after every upgrade (6.4r2 this morning) the second unit goes red. Even though I am installing on the cluster virtual IP it doesn't concurrently install on the second member -- only on the primary member.

It also never does a resync. I previously tried overnight, just to see what it would do. Nothing.

I have found that I need to power down the second member. I leave it off about 10 seconds, then power up. After about 15 minutes it will go green in the Status page.

When it reboots it resynchs.
