The third "important" admonition on this page about Persistent storage using iSCSI contains somewhat anthropomorphic language ("OpenShift assumes that all nodes in the cluster have already configured..."). This can be updated to have a user focus and better align with the IBM style guide.

Additionally, per rhn-engineering-jsafrane, the mentioned iscsi-initiator-utils package is already installed when using RHCOS, so this detail may be added to the admonition to make it more informative.
