23 Managing MSCS clusters
Cluster Monitor is a core component of Systems Insight Manager, and adds the ability to monitor and manage
multi-node clusters. Cluster Monitor also manages multiple cluster platforms in a heterogeneous environment.
Procedure 23-1 Managing clusters
1. Access the Cluster Monitor page by using one of the following methods:
• Method 1:
Select Tools→System Information→Cluster Monitor.
Note: If no MSCS clusters are discovered, Cluster Monitor is not listed in the menu.
1.
2. Select a target MSCS cluster, and then click Run Now.
• Method 2:
1. Locate a cluster by expanding Systems under the System and Event Collections panel
and selecting a cluster collection.
The appropriate cluster collection table appears in the workspace.
Note: Only MSCS clusters you are authorized to access appear on the cluster table view
page.
2. Choose one of the following:
• In the Cluster Name column, click the name of the MSCS cluster.
• In the CS column on the cluster table view page, click the MSCS cluster status icon.
The Cluster Monitor page appears for that cluster.
2. Select from the following tabs available on the Cluster Monitor page. Every tab includes a Problem
Info section that provides details about problems reported on the tab. For example, on the Cluster tab,
this section includes status information if the cluster has a status of anything other than Normal.
Each tab also includes a Last Update field that displays the last time the information on the tab was
updated.
• Cluster Use to view cluster information such as the cluster status, name, IP address, and quorum.
• Nodes Use to view node information such as the node status, name, and IP address.
• Network Use to view network information such as the network status, name, mask, state, role,
and description.
• Resources Use to view MSCS Resource information for the cluster, including the status, name,
IP address, state, group, owner node, type, and drive of the resources.
MSCS status
The Cluster Monitor page summarizes cluster status as defined by MSCS and lists the status and values of
MSCS-defined cluster attributes.
