Kernel Boot parameter length exceed limits in multipath FCP setup during RHEL installation on IBM Z

Solution In Progress - Updated -

Issue

Using more than one LUN during the installation of Red Hat Enterprise Linux (RHEL) with a multi-path FCP (Fibre Channel Protocol) setup, causes the kernel boot parameters to exceed the maximal supported length. This issue arises due to the LUN auto-scan behavior, which results in an excessively long kernel boot parameter string.
