Installing RMC RPMs on RHEL

The commands to install the RMC (Resource Monitoring and Control) RPMs on your Red Hat Enterprise Linux (RHEL) system are as follows. Let's break down each command and understand its function:

1. Downloading the IBM Power Repository:

wget https://public.dhe.ibm.com/software/server/POWER/Linux/yum/download/ibm-power-repo-latest.noarch.rpm This command downloads the latest IBM Power repository RPM package using the wget tool. This repository contains various packages specific to IBM Power systems, including the RMC tools.

2. Installing the Repository:

rpm -iv ibm-power-repo-latest.noarch.rpm This command uses the rpm tool to install the downloaded repository. The -i option specifies installation, and the -v option provides verbose output.

3. Configuring the Repository:

/opt/ibm/lop/configure This command configures the IBM Power repository for use with yum. It sets up the necessary configuration files and ensures access to the repository packages.

4. Checking Configuration Success:

echo $? This command prints the exit code of the previous command. If the configuration was successful, the exit code will be 0.

5. Installing RSCT Basic Package:

yes | yum install rsct.basic This command installs the rsct.basic package, which provides the basic functionalities of Reliable Scalable Cluster Technology (RSCT). RSCT is a core component of RMC and enables communication between the management console and VMs.

6. Installing DynamicRM Package:

yes | yum install DynamicRM This command installs the DynamicRM package, which enables dynamic storage detection for VMs. This means VMs will automatically discover and utilize newly added storage while running.

Note:

The yes command is used to bypass any prompts during the installation process.

These commands assume you have root privileges and an internet connection.

Additional Information:

Depending on your specific needs, you may need to install additional RMC RPMs beyond rsct.basic and DynamicRM. Refer to the IBM documentation for guidance on choosing the appropriate packages.

Ensure you have downloaded the correct RMC RPMs for your RHEL distribution.

Consider implementing best practices for managing RMC connections, like keeping your system updated and monitoring RMC status.

By following these steps and implementing best practices, you can successfully install the RMC RPMs on your RHEL system and leverage its functionalities for efficient virtual machine management.
