hpevtIofanFail

Module: HPIPFTRAP-MIB

OID (symbolic): HPIPFTRAP-MIB::hpevtIofanFail

OID (numeric): 1.3.6.1.4.1.11.2.23.35.0.7836

Node type: NOTIFICATION-TYPE

Description: An IO Chassis cooling fan has failed. Depending on the number of fans still operating, the cabinet may or may not shut down. View Error Log entries to determine if the cabinet is operating. If many log entries call out entities powering off during the same time frame as this IOFAN_FAIL, the cabinet has probably shutdown. Carefully review the log for the first few events within the same time frame for the root cause of the problem. The Guardian Service Processor command, PS, will show a detailed power status for a cabinet. The +48V LED on the Front Panel Board not lit, power is not enabled to the cabinet, indicating the cabinet IO Chassis fans have probably gone from N to N - 1 status requiring an immediate cabinet shutdown.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' HPIPFTRAP-MIB::hpevtIofanFail
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.11.2.23.35.0.7836

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:56943->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (202639471) 23 days, 10:53:14.71
