Auto Save On Crash Or Rollover; Last Restart Reason; Hardware Watchdog Timer - Dell Force10 S4810P Configuration Manual

Auto Save on Crash or Rollover

Exception information on for 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, the TRACE_LOG_DIR files can be reached by FTP or by using the
from the flash://TRACE_LOG_DIR directory.
On a Standby unit, the TRACE_LOG_DIR files can be reached only by using the
from the flash://TRACE_LOG_DIR directory.
Note: Non-management member units do not support this functionality.

unresponsive. This is a last resort mechanism intended to prevent a manual power cycle.
