stoprpnode Command

Purpose

Brings one or more nodes offline to a peer domain.

Syntax

stoprpnode [-f] [-h] [-TV] node_name1 [node_name2...]

Description

The stoprpnode command brings an online node offline to a peer domain. The peer domain is determined by the online peer domain where the command is run. The command must be run from a node that is online to the desired peer domain.

The -f flag must be used to override a subsystem's rejection of the request to take a node offline. A subsystem may reject the request if a node resource is busy, such as in the case of a shared disk. Specifying the -f flag in this situation indicates to the subsystems that the node must be brought offline regardless of the resource state.

If this command is used to bring more than one node offline by specifying more than one node_name parameter, and the node that this command is running on is in the list, it will be brought offline last.

Flags

-f: Forces the subsystems to accept the stop request when it otherwise would not.
-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 that is to be brought offline to the peer domain. To list the peer domain node names, run the lsrpnode command.

Security

The user of the stoprpnode command needs write permission for the IBM.PeerNode resource class on each node that is to be stopped in 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.

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 to the peer domain. The node to be brought offline must be reachable from the node on which the command is run.

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

In these examples, nodeA and nodeB are online to ApplDomain.

To bring nodeB offline, run this command on nodeA:
```
stoprpnode nodeB
```
To bring nodeB offline and force the offline request, run this command on nodeA:
```
stoprpnode -f nodeB
```
