2.3 Using SYSMAN to Centralize System Management
2.3.3 Understanding a SYSMAN Management Environment
When you use SYSMAN, you must define the management environment you
will be working in. The management environment is the node or nodes on which
subsequent commands will execute.
By default, the management environment is the local node (the node from which
you execute SYSMAN). To execute commands on one or more other nodes, you
can redefine the management environment to be any of the following:
• Your own OpenVMS Cluster system
• A subset of nodes in your OpenVMS Cluster system
• A nonclustered node available through DECnet
• Another OpenVMS Cluster system
• A subset of nodes in another OpenVMS Cluster system
• Any group of individual nodes
Refer to Figure 2–2 during the following discussion of management
environments.

You can use NODE21 as the management environment, or you can define the
environment to be any node, group of nodes, or cluster shown in Figure 2–2.
If you execute SYSMAN from NODE21, then NODE21 is the local node; it is the
management environment when SYSMAN starts. All other nodes are remote
nodes.
