Chapter 9 – Troubleshooting

The RamSan is a complex system with many redundant features to safeguard your data; however, components can fail. The RamSan has many ways to inform the user about what is happening inside the system. Rather than try to list all the different possible failures, this section explains how to identify and solve problems.

9.1 System Event Log

In the case of a system failure, review the system event log to determine what failed and when it failed. This information is invaluable in determining why a component failed and provides a timeline for the system administrator to follow. Before contacting Texas Memory Systems, please have a copy of this log available.

9.2Support Log

The support log provides a snapshot of all current configuration settings. Before contacting Texas Memory Systems, please have a copy of this log available.
