HP 3PAR Red Hat Enterprise Linux andOracle Linux Implementation Guide

AbstractThis implementation guide provides the information you need to configure an HP 3PAR StoreServ Storage with Red Hat EnterpriseLinux (RHEL) 4, RHEL 5, RHEL 6, and Oracle Linux (OL). General information is also provided on the basic steps required toallocate storage on the HP 3PAR StoreServ Storage that can then be accessed by the RHEL host.
