To test the components of a FailSafe system using the Cluster Manager GUI, perform the following steps:
Select Task Manager on the FailSafe Toolchest.
On the left side of the display, click on the “Diagnostics” category.
Select one of the diagnostics tasks that appear on the right side of the display: “Test Connectivity,” “Test Resources,” or “Test Failover Policy.”
When you select the “Test Connectivity” task from the Diagnostics display, you can test the network and serial connections on the nodes in your cluster by entering the requested inputs. You can test all of the nodes in the cluster at one time, or you can specify an individual node to test.
When you select the “Test Resources” task from the Diagnostics display, you can test the resources on the nodes in your cluster by entering the requested inputs. You can test resources by type and by group. You can test the resources of a resource type or in a resource group on all of the nodes in the cluster at one time, or you can specify an individual node to test. Resource tests are performed only on nodes in the resource group's application failover domain.
When you select the “Test Failover Policy” task from the Diagnostics display, you can test whether a failover policy is defined correctly. This test checks the failover policy by validating the policy script, failover attributes, and whether the application failover domain consists of valid nodes from the cluster.
