IDP Series HA Signaling Script Log Messages

HA signaling log messages are written to /var/idp/device/sysinfo/logs/hasignal.timestamp. HA signaling log messages are not sent to NSM or syslog servers. Table 8 explains the conditions that generate HA signaling log messages.

Table 8: IDP Series HA Signaling Script Log Messages

Example Log

When Triggered

20101210001730:[WARN]:The UP & RUNNING nics are eth2 eth3 eth4 eth5 eth8 eth9 eth12 eth13

Every time the IDP engine is restarted, IDP device rebooted, ACM configuration changed, or HA interface signaling script restarted, the HA signaling script generates a pair of logs listing traffic interfaces.

This log lists the interfaces currently monitored by the HA interface signaling script.

20101210001730:[WARN]:The considered nics are eth2 eth3 eth4 eth5 eth6 eth7 eth8 eth9 eth10 eth11 eth12 eth13

Every time the IDP engine is restarted, IDP device rebooted, ACM configuration changed, or HA interface signaling script restarted, the HA signaling script generates a pair of logs listing traffic interfaces.

The log lists the forwarding interfaces enabled in the ACM Configuring Virtual Routers page.

20101210001730:[WARN]:Disabling HA signalling for engine failure, since auto-recovery is enabled

When auto recovery is enabled.

20101210005113:[WARN]:SIGNAL handler:HA signalling script gracefully getting terminated

Every time the IDP engine is restarted, IDP device rebooted, ACM configuration changed, or HA interface signaling script restarted, the HA signaling script is stopped and restarted.

20101210010839:[WARN]:NIC monitoring: One or more interfaces are down due to hw/sw failure

When interfaces are brought down.

20101210010839:[WARN]:NIC monitoring: About to bring down all the up & running interfaces

When any traffic interface goes down or IDP engine goes down (autorecovery disabled), all traffic interfaces are brought down (interface signaling enabled).

20101212224853:[WARN]:NIC monitoring: Interfaces with hw/sw issue are now up & running

When the downed interface comes up and the active node resumes (interface signaling enabled).

20101210010839:[WARN]:NIC monitoring: Blocking STP or similar such traffic

When interface signaling is disabled and a failover condition happens.

20101212224853:[WARN]:NIC monitoring: Allowing STP or similar such traffic

When the downed interface comes up and the active node resumes (interface signaling disabled).

20101212224853:[WARN]:ENGINE monitoring:IDP engine 2 terminated, about to signal third-party HA device

When autorecovery is disabled and one of the IDP engines goes down.

20101212224864:[WARN]:ENGINE monitoring:Bringing down any up & running interfaces

When autorecovery is disabled, interface signaling is enabled, and one of the IDP engines goes down.

20101212224864:[WARN]:ENGINE monitoring:Blocking STP or similar such traffic

When autorecovery is disabled, interface signaling is disabled, and one of the IDP engines goes down.

20101212225126:[WARN]:Peer port modulator is being deliberately stopped.

If PPM and interface signaling are both enabled, this message warns you that the interface signaling script has stopped the PPM daemon.
