E-Series TeraScale Debugging and Diagnostics | 1089
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
Debug commands
FTOS supports an extensive suite of debug commands for troubleshooting specific problems while
working with Dell Force10 technical support staff. All debug commands are entered in privileged EXEC
mode. Refer to the FTOS Command Reference for details.
Hardware watchdog timer
The hardware watchdog command automatically reboots an FTOS switch/router with a single
RPM that is unresponsive. This is a last resort mechanism intended to prevent a manual power
cycle.
Show hardware commands
The show hardware command tree consists of privileged EXEC commands created or changed specially
for use with the E-Series. These commands display information from a hardware sub-component, such as
the Buffer and Traffic Management (BTM) ASIC and the Forwarding and Packet Classification (FPC)
ASIC. They should be used only under the guidance of Dell Force10 technical support staff.
The following table lists the show hardware commands. For detailed information on these and other
commands, refer to the FTOS Command Line Interface Reference document.
