Server: Enter the name or IP address of the server.

Server Severity: When a server fails completely because of a power

failure or other serious event, Matrix Server attempts to move any virtual

hosts from the network interfaces on the failed server to backup network

interfaces on healthy servers in the matrix.

After the server is restored to normal operation (for example, the power is

restored and the server is rebooted), it is by default made available to host

virtual hosts. If a failure of the server caused failover of virtual hosts,

recovery of that server will cause the same set of virtual hosts to

automatically “failback” to network interfaces on the original server.

There are two settings for Server Severity:

AUTORECOVER. This is the default behavior. Virtual hosts

automatically fail back to network interfaces on the original server after it

is restored to normal operation.

NOAUTORECOVER. After the server recovers, it is not made available

to host virtual hosts. Instead, Matrix Server disables the server. (You will

need to re-enable the server with the Management Console or mx utility).

The NOAUTORECOVER setting can be useful when integrating Matrix

Server with custom applications, where additional actions may be

necessary after server recovery and before the server is made available to

host services provided by virtual hosts.

After adding a new server, it appears on the Servers window. In the

following example, two servers have been added to a matrix.
