The clusters on OSF dgux 4.x work like such:
physical_hostname1 logical_hostname1 physical_hostname2 logical_hostname2 physical_hostname3 logical_hostname3 physical_hostname4 (failover host)
If logical_hostname2 fails, it will failover including the filesystems to physical_hostname4. So the picture will look like this:
physical_hostname1 logical_hostname1 physical_hostname2 DOWN physical_hostname3 logical_hostname3 physical_hostname4 logical_hostname2 (failover host)
There are common processes and filesystems for each physical_hostname that are easily reported. How would I report different processes and filesystems for the logical_hostnames? Note, physical_hostname1 and logical_hostname1 do have different IPs.
Not to get into too much detail, but the way I have it setup now, I check for failover every 10 minutes, and if it has occurred, I copy new bb-proctabs, bb-dftabs, and bb-exttabs over top the current ones and restart the BB client. Same, if a fail-back to the home host has occurred. Perhaps I will have to do something similar with the hobbit client?
