Dell Force10 C150 Configuration Manual page 1207

The three CPUs use Fast Ethernet connections to communicate to each other and to the line card CPUs
using Inter-Processor Communication (IPC). The CP monitors the health status of the other processors
using heartbeat messaging exchange.
Message 6 CP monitor
%RPM1-P:CP %IPC-2-STATUS: target rp2 not responding
%RPM0-S:CP %RAM-6-FAILOVER_REQ: RPM failover request from active peer: Auto failover on failure
%RPM0-S:CP %RAM-6-ELECTION_ROLE: RPM0 is transitioning to Primary RPM.
%RPM0-P:CP %TSM-6-SFM_SWITCHFAB_STATE: Switch Fabric: UP
FTOS automatically saves critical information about the IPC failure to NVRAM. Such information
includes:
• Status counters on the internal Ethernet interface
• Traffic profile of the inter-CPU bus
• Kernel drops
• High CPU exception conditions
Upon the next boot, this information is uploaded to a file in the CRASH_LOG directory. Use the following
command sequence beginning in EXEC mode to capture this file for analysis by the Dell Force10 TAC.
Step Task
1 Display the directories in flash memory. The output
should include:
1 drwx 2048 Jan 01 1980 00:00:06
CRASH_LOG_DIR
2 Change to the CRASH_LOG directory.
3
View any saved files in the CRASH_LOG
directory. The naming convention is:
sysinfo_RPMIDProcessorID _ timestamp
For example:
sysinfo_RPM1CP_20060616_013125
sysinfo_RPM1RP1_20060616_013248
sysinfo_RPM1RP2_20060616_013249
4 View the contents of the file.
