refrsrc Command

Purpose

Refreshes the resources within the specified resource class.

Syntax

refrsrc [-h] [-TV] resource_class

Description

The refrsrc command refreshes the resources within the specified resource class. Use this command to force the Resource Monitoring and Control (RMC) subsystem to detect new instances of resources in cases where the configuration could be altered by operating system commands (mkfs, for example).

This command makes a request to the RMC subsystem to refresh the configuration of the resources within a resource class. The request is actually performed by the linked resource manager.

Any application that is monitoring resources in the specified resource class may receive events as the configuration is refreshed.

Flags

-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

resource_class: Specifies the resource class name.

Security

The user needs read permission for the Resource_class specified in refrsrc to run refrsrc. Permissions are specified in the access control list (ACL) file on the contacted system. See the RSCT Guide and Reference for information about the ACL file and how to modify it.

Exit Status

0: Command has run successfully.
1: Error occurred with RMC.
2: Error occurred with CLI script.
3: Incorrect flag on command line.

5: Error occurred with RMC that was based on faulty command line input.

Environment Variables

CT_CONTACT

When the CT_CONTACT environment variable is set to a host name or IP address, the command contacts the Resource Monitoring and Control (RMC) daemon on the specified host. If the environment variable is not set, the command contacts the RMC daemon on the local system where the command is being run. The resource class or resources that are displayed or modified by the command are located on the system to which the connection is established.

CT_MANAGEMENT_SCOPE

Determines the management scope that is used for the session with the RMC daemon to monitor and control the resources and resource classes. The management scope determines the set of possible target nodes where the resources and resource classes can be monitored and controlled. The valid values are:

0: Specifies local scope.
1: Specifies local scope.
2: Specifies peer domain scope.
3: Specifies management domain scope.

If this environment variable is not set, local scope is used.

Standard Output

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

The command output and all verbose messages are written to standard output.

Standard Error

All trace messages are written to standard error.
