Measures reported by LHClusterMgrTest
Within a management group, managers are storage systems that govern the activity of all of the storage systems in the group. The Failover Manager is a specialized version of the LeftHand OS software designed to operate as a manager and provide automated failover capability. In a cluster set up, administrators may often want to figure out the state of each manager and determine whether the manager is a failover manager or not. For this, administrators can use the LHClusterMgrTest test.
This test auto-discovers the cluster managers in the target storage cluster and for each cluster manager, this test reports the current state. This test also helps administrators determine whether the cluster manager is a failover manager or not.
Outputs of the test : One set of results for each cluster manager on the target LeftHand SAN Cluster being monitored.
