stoprpnode Command

Purpose

Takes one or more nodes offline from a peer domain.

Syntax

stoprpnode [-f] [-h] [-w [-s Seconds]] [-TV] node_name1 [node_name2...]

stoprpnode -F { file_name │ "–" } [-f] [-h] [-w [-s Seconds]] [-TV]

Description

The stoprpnode command takes an online node offline from 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.

If a Cluster-Aware AIX® (CAA) cluster is configured, no action is performed because a peer domain operation in a CAA environment exists and is online for the life of the CAA cluster.

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 take 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.

-F { file_name | "–" }

Reads a list of node names from file_name. Each line of the file is scanned for one node name. The pound sign (#) indicates that the remainder of the line (or the entire line if the # is in column 1) is a comment.

Use -F "-" to specify STDIN as the input file.

-h

Writes the command's usage statement to standard output.

-s

Specifies the wait time in seconds for all of the specified nodes to be offline before the command completes when the -s flag is used with the -w flag. If the waiting time exceeds the number of seconds, the command returns, but the offline operation continues. The default value is 300 seconds (5 minutes). Use 0 to specify that the command must not return until all of the specified nodes are offline (no timeout on waiting).

-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.

-w

Waits for all of the specified nodes to be offline before the command completes. Use the -s flag to specify the waiting time in seconds.

Parameters

node_name1 [node_name2...]

Specifies the peer domain node names of the nodes that are to be brought offline from the peer domain. You must specify the node names in exactly the same format as they were specified with the addrpnode command or the mkrpdomain command. 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.

CT_IP_AUTHENT

When the CT_IP_AUTHENT environment variable exists, the RMC daemon uses IP-based network authentication to contact the RMC daemon on the system that is specified by the IP address to which the CT_CONTACT environment variable is set. CT_IP_AUTHENT only has meaning if CT_CONTACT is set to an IP address; it does not rely on the domain name system (DNS) service.

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.

Implementation Specifics

This command is part of the rsct.basic.rte fileset for the AIX® operating system.

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.
