hpevtPdhcGetSm4Timeout

Module: HPIPFTRAP-MIB

OID (symbolic): HPIPFTRAP-MIB::hpevtPdhcGetSm4Timeout

OID (numeric): 1.3.6.1.4.1.11.2.23.35.0.8151

Node type: NOTIFICATION-TYPE

Description: This event is emitted after the PDHC has waited longer than a maximum expected time to obtain control of the PDH bus semaphore. The PDHC will continue waiting for control of the PDH bus semaphore until System FW relinquishes control of the semaphore, or the Cell is powered off using the MP's PE command. While waiting for the PDH bus semaphore, the PDHC will NOT perform its normal duties such as monitoring the Cell status, and passing messages from the system to the MP, and the PDHC heartbeat will not blink. The data field contains debug data that may be useful for developers. Data_byte[0] = last value read from PDHC's address for the microSemaphore register. Data_byte[1] = boolean indicator (1=set,0=not_set) of whether the PDHC's flag is set. Data_byte[2] = boolean indicator (1=set,0=not_set) of whether the System FW's flag is set.

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::hpevtPdhcGetSm4Timeout
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.11.2.23.35.0.8151

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:
