Testing host failure
In this scenario, the host where the application runs is lost. Eventually, all the hosts in the cluster or system zone are lost.
To perform the host failure test
Halt or shut down the host where the application runs (hosta).
The service group fails over to hostb.
Halt or shut down hostb.
In a global cluster, a cluster down alert appears and the service group fails over to the site B or site C, depending on the values of the ClusterList and ClusterFailoverPolicy attributes.
In a replicated data cluster, the service group fails over to the site B or site C, depending on the values of the SystemZones, FailoverPolicy, AutoFailover, ClusterList, and ClusterFailoverPolicy attributes.
- Power on the two hosts that were shut down.
- Switch the service group to its original host when VCS starts.
Do the following:
In the Service Groups tab of the Cluster Explorer configuration tree, right-click the service group.
Click Switch To and click the system on which the service group was initially online (hosta).
The service group comes online on hosta.
