C-Series Debugging and Diagnostics | 1173
FTOS actually saves up to three persistent files depending upon the type of failure. When reporting an
RPM failover triggered by a loss of the IPC or IRC heartbeats, look for failure records in the following
directories:
— Application or kernel core dump RP in the CORE_DUMP_DIR
— CP trace log file (look for a filename with the phrase “failure_trace”) in the
TRACE_LOG_DIR
— RP and/or CP sysinfo file in the CRASH_LOG_DIR, as explained above
Bootup diagnostics
During bootup and reset of a card, diagnostics check the status of key hardware sub-components and verify
that all ASICs initialize successfully.
Recognizing bootup failure
Any detected failures or errors during bootup are reported via Syslog. The messages in Message 5 and
Message 6 might be reported for line card failures and RPMs, respectively.
Troubleshoot bootup failure
If these messages are seen, collect the output of the show console lp and show tech commands and contact
the Dell Force10 Technical Assistance Center.
Environmental monitoring
All C-Series components use environmental monitoring hardware to detect overtemperature, undervoltage,
and overvoltage conditions. Use the
show environment command to monitor the components for any major
or minor alarm conditions. The output in Figure 60-5 displays the environment status of the RPM.
