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 command from the flash://TRACE_LOG_DIR directory.
show file
On a Standby unit, you can reach the TRACE_LOG_DIR files only by using the
the flash://TRACE_LOG_DIR directory.
Note: Non-management Member units do not support this functionality.
