Change of Cluster Member priority when the kernel parameter 'fwha_freeze_state_machine_timeout' is enabled may cause network outage
When the user changes the priority of the members via SmartDashboard and then installs policy, the cluster configuration will be restarted on each member (transparently for traffic) and will be updated with the new Member Priorities.
By default, the kernel parameter '
fwha_freeze_state_machine_timeout' is disabled. Starting in R75.40VS and R76, by default this kernel parameter is enabled and its value is set to 30 seconds.
When the kernel parameter '
fwha_freeze_state_machine_timeout' is enabled (set to some value per either of these solutions - sk25971 / sk32488), the cluster configuration on members will not be updated correctly even though output of "
cphaprob state" command shows that the Member IDs and their state have changed.
