Output

The output of this script will show you the status of hardware and network prerequisites as passed or failed. The script will create an additional file using the name specified within "Customer Name" and "Component Name". For example: "Netmonastery_Core_hardwarecheck.txt

Review the checks marked as failed and resolve the same with the help of your System or Network Administrators. Once all the checks are marked as passed you can consider pre-requisites to be ready and initiate the Deployment process.
