Error description
Load Balancer for IPv4 and IPv6 for AIX sends HA packet every 1 second. We expected the HA packet should be sent every 0.5 second. With the default hatimeout value, 2 seconds, it might have a risk for the unexpected failover to be occurred.
Local fix
Increase hatimeout value to mitigate a risk of unexpected failover.
Problem summary
**************************************************************** * USERS AFFECTED: Customers using Load Balancer for IPv4 and * * IPv6 on AIX. * **************************************************************** * PROBLEM DESCRIPTION: Load Balancer for IPv4 and IPv6 for * * AIX sends HA packet every 1 * * second in stead on every .5 second. * **************************************************************** * RECOMMENDATION: * **************************************************************** Load Balancer for IPv4 and IPv6 for AIX sends HA packet every 1 second in stead on every .5 second.
Problem conclusion
The problem occurred because HA timer was set to expire for every 1 second. Now it is set for every .5 second timeout. This fix will be available in FP version 8.5.5.9, 8.0.0.12 and 7.0.0.41
