SYSMAN> SET ENVIRONMENT/CLUSTER/NODE=NODE24
Remote Password:
%SYSMAN-I-ENV, current command environment:
Clusterwide on remote cluster NODE24
Username ALEXIS will be used on nonlocal nodes
SYSMAN> DO SHOW TIME
%SYSMAN-I-OUTPUT, command execution on node NODE24
13-AUG-2000 13:07:54
%SYSMAN-I-OUTPUT, command execution on node NODE25
13-AUG-2000 13:10:28
The SET ENVIRONMENT command in this example defines the management
environment to be a cluster that includes NODE24—that is, Cluster 2.
2.3.4.2 Using Logical Names to Organize Management Environments
If you want to organize the nodes in your cluster according to specific categories
(for example, all CI-based nodes or all nodes with C installed), you can define
logical names to use with the SET ENVIRONMENT/NODE command, as follows:
1. Create the logical name table SYSMAN$NODE_TABLE by putting the
following command into the file SYS$MANAGER:SYLOGICALS.COM, which
is executed during system startup:
$ CREATE/NAME_TABLE/PARENT=LNM$SYSTEM_DIRECTORY SYSMAN$NODE_TABLE
2. Define one or more logical names to be a node or list of nodes by putting a
command similar to the following into SYS$MANAGER:SYLOGICALS.COM:
$ DEFINE CI_NODES NODE21,NODE22,NODE23/TABLE=SYSMAN$NODE_TABLE
3. When you set your SYSMAN environment from the DCL level, specify one of
the logical names you created for this purpose. For example:
$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> SET ENVIRONMENT/NODE=(CI_NODES)
Remote Password:
%SYSMAN-I-ENV, current command environment:
Individual nodes: NODE21,NODE22,NODE23
At least one node is not in the local cluster.
Username SYSTEM will be used on nonlocal nodes.
You can also define logical names for VAX and Alpha nodes in a dual-architecture
OpenVMS Cluster system, as explained in Section 22.6.
Example
The following example demonstrates how you can define multiple logical names
to organize several management environments:
$ CREATE/NAME_TABLE/PARENT=LNM$SYSTEM_DIRECTORY SYSMAN$NODE_TABLE
$ DEFINE CI_NODES SYS2,SYS8/TABLE=SYSMAN$NODE_TABLE
$ DEFINE C NODE21,NODE22,NODE23/TABLE=SYSMAN$NODE_TABLE
$ DEFINE PASCAL NODE23,NODE18,CI_NODES/TABLE=SYSMAN$NODE_TABLE
$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> SET ENVIRONMENT/NODE=(C,PASCAL)
Remote Password:
%SYSMAN-I-ENV, current command environment:
Individual nodes: NODE21,NODE22,NODE23,NODE18,SYS2,SYS8
At least one node is not in the local cluster.
Username SYSTEM will be used on nonlocal nodes.
