HP 3PAR StoreServ storage devices

• If you are using storage domains, when you add one FC device type and one iSCSI device type to the same storage system, both devices must reside in the same domain.

• When you add an iSCSI device you must have connectivity from the targeted compute node to the 3PAR storage system iSCSI port. If you do not configure the connection, block storage volumes will not attach to virtual machine instances.

• iSCSI devices are created with Challenge Handshake Authentication Protocol (CHAP) disabled by default. CHAP is not supported in this release of CloudSystem.

• Special characters in an HP 3PAR iSCSI host name cause the Cinder driver host creation to fail when attaching a volume. For iSCSI host names, use the characters [a-z][A-Z][. -] and [0-9] only.
