High Availability Events

---

This appendix provides a list of the high availability events displayed in EventVision and the defaults for the failover parameters. For more information, see the Cisco Active Network Abstraction User Guide.

Table A-1 shows Cisco ANA's pre-configured failover defaults.

Table A-1 Failover Defaults

#	Description	Measured in milliseconds	Entry Name in Registry
1	Grace period (time from system startup in which events are not raised)1	1800000 (30 minutes)	Delay
2	Timeout for AVMs	300000 (5 minutes)	Timeout
3	Timeout for units	300000 (5 minutes) Note This is the initial recovery period defined in minutes,. This period includes device polling and inventory build-up. End-to-end services, such as RCA and topology, may take longer before they become available.	Timeout
4	AVMs repeatedly not responding	Tries a maximum of 5 times to restart the AVM within 10800000 ms (180 minutes) (if more, suspends the AVM).	maxTimeoutReloadTime maxTimeoutReloadTries

1 The grace period defines the amount of time that the system does not perform high availability operations of any kind on the configured target (either the AVM or the unit). There is one exception to this: When the configured target responds for the first time with ping, the grace period is over.

Table A-2 lists Cisco ANA's high availability events.

Table A-2 High Availability Events

Event	Message	Severity
Watchdog Protection
The AVM times out (see # 2 in the above Pre-configured default table)	AVM 107 not responding: ANA Unit = 1.1.1.1 AVM = 107 This is followed by:	Major
	AVM 107 is shutting down. ANA Unit = 1.1.1.1	Minor
	AVM 107 is starting. ANA Unit = 1.1.1.1	Minor
The AVM repeatedly does not respond (see # 4 in the Pre-configured default table)	AVM 107 suppressed: ANA Unit = 1.1.1.1 AVM = 107	Major
Unit Protection
The unit times out (when a standby unit is available) (see # 3 in the Pre-configured default table)	Server 1.1.1.1 not responding. Raising Redundant machine = 3.3.3.3	Major
A unit times out (without a standby unit being available) (see # 3 in the Pre-configured default table)	Server 1.1.1.1 not responding. No Redundant machine available	Major
Manually switching to the standby unit	Server 1.1.1.1 manual failover initiated No Redundant machine available	Major
	Server 1.1.1.1 manual failover initiated Raising Redundant machine = 3.3.3.3	Major
