Using Administration Tools and Configuration Files to Troubleshoot

The Netra HA Suite provides a suite of tools and configuration files for maintaining and debugging your cluster environment. Because the Netra HA Suite runs on the Solaris Operating System, the Solaris tools and configuration files are also useful.

When your cluster produces an error, use the tools to determine the cause of the problem. For information about these tools, see the Netra High Availability Suite 3.0 1/08 Foundation Services Cluster Administration Guide.

For information about the individual tools, see their man pages in section 1M of the Netra High Availability Suite 3.0 1/08 Foundation Services Reference Manual. Similarly, for information about the individual configuration files, see their man pages in section 4 of the Netra High Availability Suite 3.0 1/08 Foundation Services Reference Manual.
