Microsoft Cluster Server environment
To monitor resources in an MSCS environment, you must be aware of IBM Spectrum® Control requirements.
In an MSCS environment, you can collect information about local resources for a clustered node and the resources in a cluster resource group. The Storage Resource agent for IBM Spectrum Control is not cluster aware, so it cannot run in the cluster resource group and fail over from one node to another. However, the agent supports failover of a clustered file system so that IBM Spectrum Control probes can continue to work when the clustered file system is moved from one node to another.
The Storage Resource agent that runs on the node that hosts the cluster resource group is that agent discovers the resources on that cluster resource group.
Restriction: You
cannot use IBM Spectrum
Control to
monitor a clustered database application.
To use IBM Spectrum
Control in
an MSCS cluster environment, consider the following requirements:
- Server requirement
- Not applicable. You cannot install the IBM Spectrum Control server on a node in an MSCS cluster.
- Client requirement
- Not applicable. You cannot install the IBM Spectrum Control client on a node in an MSCS cluster.
- Agent requirements
- You must install a Storage Resource agent on each node in an MSCS cluster. IBM Spectrum Control can monitor and report only on nodes where a Storage Resource agent is installed and configured to run in daemon mode.
- If the Storage Resource agent port is behind a firewall, that port needs to be opened for all virtual server and cluster resource group addresses.
- All agents that are installed in a cluster must use the same port
number to communicate with IBM Spectrum Control. Agents
in other clusters can be configured with a different port address.Tip: All agents in a cluster must use the port address used by the other agents in that cluster.
