Best Practices for Cluster Management

Recommended best practices for effective management of cluster:

1. Perform all HySecure administration from Active node in the cluster.
2. Make sure on every node in cluster NTP is configured and is in running state.
3. Make sure that host file entry on each node should be same.
4. To verify log please login as certificate user on Active or Standby gateway and check log.
5. Always reboot or shutdown gateway from management console or OS console.
6. Check health status of each node by logging into SHELL and running /etc/sysconfig/ha/healthstatus.
7. Ensure that all maintenance activities like HySecure upgrade, failover, etc must be done with at least 2 hour maintenance window. It is advised to do the administration during off hours.
8. Do not change ping settings on default gateway.
9. Do not keep any firewall between the nodes in the cluster and they must be installed within same subnet.
10. Take regular backup of configuration by taking "User Backup". Also take "System Backup" for all certificate backup also.
