Table 8-1 shows the tests you can perform with Linux FailSafe diagnostic commands:
Table 8-1. FailSafe Diagnostic Test Summary
Checks that the resource type parameters are set
Check that the parameters are syntactically correct
Validates that the parameters exist
Tests all resources defined in the resource group
Checks that the failover policy exists
Checks that the failover domain contains a valid list of hosts
Checks that the control interfaces are on the same network
Checks that the nodes can communicate with each other
Checks that the nodes can reset each other
All transactions are logged to the diagnostics file diags_nodename in the log directory.
You should test resource groups before starting FailSafe HA services or starting a resource group. These tests are designed to check for resource inconsistencies which could prevent the resource group from starting successfully.
