Troubleshoot Matrix Problems

Matrix Server Fails to Start

If the Matrix Server service fails to start on a server, check that the domain

name of the server is configured in the DNS suffix list. The DNS suffix list

is configurable via the Advanced TCP/IP Properties.

The Server Status Is “Down”

If a server is running but Matrix Server shows it as down, follow these

diagnostic steps:

1. Verify that the server is connected to the network.

2. Verify that the network devices and interfaces are properly configured

on the server.

3. Ensure that the ClusterPulse process is running on the server.

4. Verify that the same version of Matrix Server is installed on all servers

in the matrix.

A Running Service Is Specified as Down

If Matrix Server indicates that a service is down even though it is running,

the service might not be sending any information to Matrix Server. Matrix

Server will conclude that the service is down even if the TCP connection

succeeds. In particular, if an HTTP server is monitored by a FTP monitor,

the HTTP server is considered down.

Also check the following:

1. Verify that the server is connected to the network.
