Expected behavior
Worker nodes are configured with iscsid and multipathd services enabled and /etc/multipath.conf created.
Additional context
I'm lead to believe that OCP 4.19 worker nodes identify themselves as rhel instead of rhcos as of OCP 4.19, however I don't have an older version of OCP to compare to. This is also consistent with the change that regular RHEL worker nodes are no longer supported. Installed worker node's os-release and redhat-release have been attached to the issue.
