Configuring Resource Monitoring and Control (RMC)

Use this procedure to configure Resource Monitoring and Control (RMC) and to verify that RMC is installed correctly.

The Partition Load Manager server uses RMC to communicate with the managed logical partitions.

The RMC setup comprises host authentication and user authorization. The host authentication involves a public key exchange between the Partition Load Manager server and the managed nodes (partitions). This allows the Partition Load Manager server to connect, or create a session, to the managed system. The user authorization involves adding an entry to the RMC ACL (Access Control) file and allows the plmuser (the Partition Load Manager server) access to the required resource class. The plmsetup script automates these tasks using remote shell commands. If the remote shell is unavailable or not configured, the administrator can perform these tasks manually.

Run the following shell script as the root user on the managing machine that will run the Partition Load Manager:

/etc/plm/setup/plmsetup

After the script runs successfully, the RMC ACL file on the remote machine will have an entry similar to the following:

IBM.LPAR            plmuser@plmserver1.domain.com      *       rw

The setup procedure takes the following as arguments:

The user ID under which the Partition Load Manager is to run
The host name of the partition

This user ID is used to set up the RMC ACL files on the logical partitions. ACL files are used to authenticate authorized users for each resource class when they connect to the RMC subsystem. Only this user will be permitted access to the Partition Load Manager. Only the authorized user can run Partition Load Manager. Any user is able to run commands that only display data.

Resource Monitoring and Control (RMC) configuration for the Partition Load Manager

Configure RMC for the Partition Load Manager by doing the following steps.

Select Set up Management of Logical Partitions.
- Authenticated user name: plmuser
Select Automatically setup with each partition in the policy file.
- Policy file name: /etc/plm/policies/plm1
Click OK.

This configuration can also be done using the command line if you are the root user on the Partition Load Manager server:

/etc/plm/setup/plmsetup lpar_hostname plmuser

To run this command, you must have rsh and rcp access. After the setup has been run, you can delete the .rhosts file.
