lsrpnode Command

Purpose

Displays information about one or more of the nodes that are defined in the online peer domain.

Syntax

lsrpnode [ -o | -O | -L ] [ -l | -t | -d | -D delimiter ] [-x] [-h] [-TV] [node_name]

lsrpnode [ -l | -t | -d | -D delimiter ] [-x] -p peer_domain [-h] [-TV]

Description

The lsrpnode command displays information about one or more of the nodes that are defined in the online peer domain. Use the command's flags and parameters to specify which information you want to display and how you want to display it. When you specify a node name, the command displays information about that node only. The -o, -O, and -L flags also limit the information this command displays. The -o flag displays information about nodes that are online. The -O flag displays information about nodes that are offline. The -Lflag displays information about the local node, which is the node the command runs on.

By default, the lsrpnode command displays information in table format (-t).

Some of the node information that is displayed follows:

Field: Description
Name: The name of the node in the peer domain
OpState: The operational state of the node
RSCTVersion: The version of RSCT that is active in the node

Flags

-o: Displays information about the nodes that are online in the peer domain.
-O: Displays information about the nodes that are offline in the peer domain.
-L: Displays information about the local node only, which is the node that the command runs on.
-p peer_domain: Displays information about nodes defined in an offline peer domain that the local node belongs to. (By default, the lsrpnode command displays information about the nodes that are defined in the domain where you are currently online.) However, this information might not reflect changes that are made to the domain after the local node is taken offline, because an offline node might not have the latest configuration.
The -p flag ignores the CT_CONTACT environment variable.
-l: Displays the information on separate lines (long format).
-t: Displays the information in separate columns (table format). This is the default format.
-d: Displays the information using delimiters. The default delimiter is a colon (:). Use the -D flag if you want to change the default delimiter.
-D delimiter: Displays the information using the specified delimiter. Use this flag to specify a delimiter other than the default colon (:) -- when the information you want to display contains colons, for example. You can use this flag to specify a delimiter of one or more characters.
-x: Excludes the header (suppresses header printing).
-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_name: Specifies the name of the node about which you want to display information. You can specify a node name or a substring of a node name for this parameter. If you specify a substring, the command displays information about any defined node with a name that contains the substring.

Security

The user of the lsrpnode command needs read permission for the IBM.PeerNode resource class on the node this command runs on. 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 in 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 display general information about the nodes in the online peer domain that nodeA belongs to, run this command on nodeA:

lsrpnode

The output will look like this:

Name          OpState       RSCTVersion 
nodeA         online        2.3.3.0   
nodeB         online        2.3.3.0     
nodeC         offline       2.3.3.0

To display general information about the nodes in the online peer domain that nodeA belongs to, with the default delimiter (but without the heading), run this command on nodeA:
```
lsrpnode -xd 
```
The output will look like this:
```
nodeA:online:2.3.3.0: 
nodeB:online:2.3.3.0: 
nodeC:offline:2.3.3.0:
```

To display general information about the nodes in the online peer domain that nodeA belongs to, in long format, run this command on nodeA:

lsrpnode -l

The output will look like this:

Name        = nodeA 
OpState     = online 
RSCTVersion = 2.3.3.0 

Name        = nodeB
OpState     = online 
RSCTVersion = 2.3.3.0   

Name        = nodeC
OpState     = offline 
RSCTVersion = 2.3.3.0
