|
||
| ## Target Physical Server: | ||
|
|
||
| You will need a HPE Gen 10 physical Server on which we will automated ESXi installation. Ultimately, it should be connected to the management network and pre-configured on HPE OneView. | ||
|
|
||
|
|
||
| ## RHEL ISO image needed | ||
| We did not automate the RHEL installation process so please choose the following when installing manualy: | ||
|
|
||
| Fetch an RHEL installation image from: | ||
| https://access.redhat.com/products/red-hat-enterprise-linux => Login => Downloard RHEL 8.4 => | ||
| Red Hat Enterprise Linux 8.4 Binary DVD | ||
| We will this ISO to deploy all the needed RHEL instances. In the Scope of this workshop we didn't plan to automate the installation of RHEL. Please choose the following guide when installing manualy: | ||
|
|
||
| - Fetch an RHEL installation image from: [HERE](https://access.redhat.com/products/red-hat-enterprise-linux) | ||
| - Login with Red Hat Customer Portal Credentials | ||
| - Download RHEL 8.4 | ||
| - Click on Red Hat Enterprise Linux 8.4 Binary DVD | ||
|
|
||
| Hint: you can copy the Link from the "Downlad Now" button and paste it directly into the download cmd / system which needs to have the ISO at the end. | ||
| E.g. download directly onto your ESXi server or a repository server in your location. | ||
