4.2 Identifying Cluster and Resource States

The Cluster Manager link in iManager gives you important information about the status of servers and resources in your cluster.

Cluster servers and resources display in different colors, depending on their operating state. When servers and resources are display with a green ball, they are in a normal (online or running) operating condition. When a server that has been part of the cluster has a red X in the icon, it has failed. When a resource is red, it is waiting for administrator intervention. When a server is gray with no break in the icon, either that server is not currently a member of the cluster or its state is unknown. When a resource is blank or has no colored icon, it is unassigned, offline, changing state, or in the process of loading or unloading.

The yellow diamond in the middle of the server icon designates the master server in the cluster. The master server is initially the first server in the cluster, but another server can become the master if the first server fails.

The Epoch number indicates the number of times the cluster state has changed. The cluster state will change every time a server joins or leaves the cluster.

The following table identifies the different resource states and gives descriptions and possible actions for each state. In iManager, click Clusters, then click Cluster Manager and enter the name of the desired cluster. A list of resources and resource states will display.

Table 4-1 Cluster Resource States

Resource State


Possible Actions


Either the Start, Failover, or Failback mode for the resource has been set to Manual. The resource is waiting to start, fail over, or fail back on the specified server.

Click the Alert status indicator. Depending on the resource state, you will be prompted to start, fail over, or fail back the resource.


The resource is not running properly and requires administrator intervention.

Click the Comatose status indicator and bring the resource offline. After resource problems have been resolved, the resource can be brought back online (returned to the running state).


The resource is in the process of loading on a server.



The properties of the resource have changed and the changes are still being synchronized in Novell eDirectory™.



Offline status indicates the resource is shut down or is in a dormant or inactive state.

Click the Offline status indicator and, if desired, click the Online button to load the resource on the best node possible, given the current state of the cluster and the resource's preferred nodes list.

Quorum Wait

The resource is waiting for the quorum to be established so it can begin loading.



The resource is in a normal running state.

Click the Running status indicator and choose to either migrate the resource to a different server in your cluster or unload (bring offline) the resource.


There isn't an assigned node available that the resource can be loaded on.

Click the Unassigned status indicator and, if desired, offline the resource. Offlining the resource will prevent it from running on any of its preferred nodes should any of them join the cluster.


The resource is in the process of unloading from the server it was running on.
