Trace Logs In addition to the syslog buffer, the Dell Force10 operating software (FTOS) buffers trace messages which are continuously written by various FTOS software tasks to report hardware and software events and status information. Each trace message provides the date, time, and name of the FTOS process. All messages are stored in a ring buffer and can be saved to a file either manually or automatically upon failover. Auto Save on Crash or Rollover Exception information on Master or Standby units is stored in the flash:/TRACE_LOG_DIR directory. This directory contains files that save trace information when there has been a task crash or timeout. On a Master unit, you can reach the TRACE_LOG_DIR files by file transfer protocol (FTP) or by using the show file command from the flash://TRACE_LOG_DIR directory. On a Standby unit, you can reach the TRACE_LOG_DIR files only by using the show file command from the flash://TRACE_LOG_DIR directory. Note: Non-management Member units do not support this functionality. Figure 39-3.
