Commands Reference, Volume 4

rmrpnode Command

Purpose

Removes one or more nodes from a peer domain definition.

Syntax

rmrpnode [-q] [-h] [-TV] node_name1 [node_name2 ...]

Description

The rmrpnode command removes the specified nodes from the online peer domain where the command is run. The command must be run on a node that is online to the peer domain in which the nodes are to be removed. The nodes to be removed must be offline to the peer domain and must be reachable from the node that runs the command. Use the stoprpnode command to bring nodes offline.

More than half of the nodes must be online to remove one or more nodes from the domain.

Flags

-q
Specifies quiet mode. The command does not return an error if the node is not in the peer domain.
-h
Writes the command's usage statement to standard output.
-T
Writes the command's trace messages to standard error. For your software service organization's use only.
-V
Writes the command's verbose messages to standard output.

Parameters

node_name1 [node_name2 ...]
Specifies the peer domain node name of the node to be removed from the peer domain definition. To list the peer domain node names, run the lsrpnode command.

Security

The user of the rmrpnode command needs write permission for the IBM.PeerNode resource class on each node that is to be removed from the peer domain. By default, root on any node in the peer domain has read and write access to this resource class through the configuration resource manager.

Exit Status

0
The command ran successfully.
1
An error occurred with RMC.
2
An error occurred with a command-line interface script.
3
An incorrect flag was entered on the command line.
4
An incorrect parameter was entered on the command line.
5
An error occurred that was based on incorrect command-line input.
6
The node does not exist in the peer domain.

Environment Variables

CT_CONTACT
Determines the system where the session with the resource monitoring and control (RMC) daemon occurs. When CT_CONTACT is set to a host name or IP address, the command contacts the RMC daemon on the specified host. If CT_CONTACT is not set, the command contacts the RMC daemon on the local system where the command is being run. The target of the RMC daemon session and the management scope determine the resource classes or resources that are processed.

Restrictions

This command must be run on a node that is online in the peer domain in which the nodes are to be removed. The nodes to be removed must also be offline to the peer domain.

Standard Input

When the -f "-" flag is specified, this command reads one or more node names from standard input.

Standard Output

When the -h flag is specified, this command's usage statement is written to standard output. All verbose messages are written to standard output.

Standard Error

All trace messages are written to standard error.

Examples

To remove the peer domain definitions of nodes nodeB and nodeC from the peer domain ApplDomain, when nodeA is defined and online to ApplDomain, and nodeB and nodeC are reachable from nodeA, run this command from nodeA:

rmrpnode nodeB nodeC

Location

/usr/sbin/rsct/bin/rmrpnode
Contains the rmrpnode command
