Installing a cluster in an LPAR on {ibm-z-title} and {ibm-linuxone-title} in a disconnected environment
In {product-title} version {product-version}, you can install a cluster in a logical partition (LPAR) on {ibm-z-name} or {ibm-linuxone-name} infrastructure that you provision in a disconnected environment.

While this document refers to only {ibm-z-name}, all information in it also applies to {ibm-linuxone-name}. |
-
You have completed the tasks in Preparing to install a cluster on {ibm-z-title} using user-provisioned infrastructure.
-
You reviewed details about the {product-title} installation and update processes.
-
You read the documentation on selecting a cluster installation method and preparing it for users.
-
You mirrored the images for a disconnected installation to your registry and obtained the
imageContentSourcesdata for your version of {product-title}. -
Before you begin the installation process, you must move or remove any existing installation files. This ensures that the required installation files are created and updated during the installation process.
ImportantEnsure that installation steps are done from a machine with access to the installation media.
-
You provisioned persistent storage using {rh-storage} or other supported storage protocols for your cluster. To deploy a private image registry, you must set up persistent storage with
ReadWriteManyaccess. -
If you use a firewall and plan to use the Telemetry service, you configured the firewall to allow the sites that your cluster requires access to.
NoteBe sure to also review this site list if you are configuring a proxy.
-
If the mirror registry that you used to install your cluster has a trusted CA, add it to the cluster by configuring additional trust stores.
-
If necessary, you can opt out of remote health reporting.
