System Management 6-7 Cluster Shared Resources Screen The Cluster Shared Resources screen (Figure 6-4) contains specific information about the cluster interconnect and all cluster resources running on the server node. From the Cluster Shared Resources screen you can: I View address, transport protocol, and physical ID of all cluster interconnects. I View the current state of all cluster resources. I Sort the interconnect information and resources by multiple criteria. Figure 6-4. Cluster Shared Resources screen All displayed interconnect and resource information is polled and updated dynamically, including status and ownership. For example, assume two drive volumes are defined in your shared storage. The primary owner of the drive volume labeled E: is server node 1. The primary owner of the drive volume labeled F: is server node 2. When the cluster is in a normal state, Insight Manager will show E: as being owned by server node 1, and F: as being owned by server node 2. When a failover event occurs, ownership of the drives changes. Assume server node 1 experiences a failure and its resources fail over to server node 2. When the failover is complete and Insight Manager polls the cluster, server node 2 will be identified as the owner of both F: and E:.

Cluster Shared Resources Screen
The Cluster Shared Resources screen (Figure 6-4) contains specific
information about the cluster interconnect and all cluster resources running on
the server node.
From the Cluster Shared Resources screen you can:
■
View address, transport protocol, and physical ID of all cluster
interconnects.
■
View the current state of all cluster resources.
■
Sort the interconnect information and resources by multiple criteria.
Figure 6-4.
Cluster Shared Resources screen
All displayed interconnect and resource information is polled and updated
dynamically, including status and ownership.
For example, assume two drive volumes are defined in your shared storage.
The primary owner of the drive volume labeled E: is server node 1. The
primary owner of the drive volume labeled F: is server node 2. When the
cluster is in a normal state, Insight Manager will show E: as being owned by
server node 1, and F: as being owned by server node 2. When a failover event
occurs, ownership of the drives changes. Assume server node 1 experiences a
failure and its resources fail over to server node 2. When the failover is
complete and Insight Manager polls the cluster, server node 2 will be
identified as the owner of both F: and E:.
