Feature Overview

iSCSI boot is supported in RHEL and since the implementation of OCPSTRAT-749 it's also available in RHCOS.

Customers require using this feature in different bare metal environments on-prem and cloud-based.

Assisted Installer implements support for it in Oracle Cloud Infrastructure (MGMT-16167) to support their bare metal standard "shapes".

This feature extends this support to make it generic and supported in the Agent-Based Installer, the Assisted Installer and in ACM/MCE.

Goals

Support iSCSI boot in bare metal nodes, including platform baremetal and platform "none".

Requirements

Assisted installer can boot and install OpenShift on nodes with iSCSI disks.

Agent-Based Installer can boot and install OpenShift on nodes with iSCSI disks.

MCE/ACM can boot and install OpenShift on nodes with iSCSI disks.

The installation can be done on clusters with platform baremetal and clusters with platform "none".
