[Oracle VM Server 3.1 and 3.2] Oracle VM Server hosts do not recognize all paths to LUNs added to Oracle Virtual Networking vHBAs without a reboot. which causes multipath-tools and Oracle FS System Manager (GUI) to display an incorrect count of the paths available to each LUN.
When adding or modifying LUNs to an Oracle Vifrtual Networking vHBA, reboot the Oracle VM Server host to see an accurate count of the available paths in the GUI.
