This appendix contains a complete IRIS FailSafe configuration file for an IRIS FailSafe cluster with WebFORCE MediaBase. The sections are
The complete IRIS FailSafe configuration file for the example configuration described in this guide is shown in Example A-1. In addition, these configuration choices have been made:
The nodes are two rackmount Origin2000 servers (rackmount Origin2000s have MMSC system controllers).
IRIS FailSafe e-mail notifications are sent to the account fsafe_admin on the local node.
If one node has a power failure, the other node should attempt to go to degraded state.
All failures should cause failovers.
Interface ef0 on mb1 has the fixed IP address mb1. Similarly, interface ef0 on mb2 has the fixed IP address mb2.
Interface ef0 on mb1 has the IP alias mbasesrvr.
If the interface ef0 on mb1 fails, its high-availability IP address (IP alias) mbasesrvr is failed over to interface ef0 on mb2.
If the private network fails, IRIS FailSafe uses the public network and the ef0 interfaces (IP addresses mb1 and mb2) instead.
The serial port /dev/ttyd2 on each node is used for the serial cable to the system controller port on the other node.
Both nodes should move to normal state after a failure.
Re-MACing isn't needed.
Example A-1 shows the configuration file for the example configuration of IRIS FailSafe with WebFORCE MediaBase in this guide. The timing values shown are the default values, with the exception of long-timeout and the start-monitor-time values. They have been increased to 120 for parameters whose default was 60 or 90.
