clcmd Command
Purpose
Takes an AIX® command and distributes it to a set of nodes that are members of a cluster.
Syntax
Description
The AIX operating system can operate in a single node or multinode configuration. A multinode configuration of the AIX operating system is a cluster configuration.
Using the AIX system management commands (such as the mkuser command, mkvg command, and lslv command), a system administrator can perform operations on the characteristics and functional definitions such as devices, file systems, and user management attributes. These system management commands can be run in a local sphere or in a cluster sphere.
In a cluster configuration, running an AIX command produces a distribution of the AIX command to all nodes participating in the cluster. Thus, an AIX system administrator can manage a group of nodes as a single object.
The enablement of AIX commands for cluster awareness has the following characteristics:
- Determines the target nodes for the AIX command
- Distributes the AIX command to the target nodes
Flags
Item | Description |
---|---|
-n clustername | Specifies the name of a cluster to send a command to. All nodes in the cluster receive the command. |
-m nodename | Specifies the node names to send a command to. The nodes must be members of a cluster. This allows the distribution of the command to a subset of nodes in a cluster. |
Examples
- To send the ps command to the oscar-test-dev1 and oscar-test-dev2 nodes
in the clusterabc cluster, enter the following
command:
clcmd -n clusterabc -m oscar-test-dev1,oscar-test-dev2 -- /usr/bin/ps
