of the Ethernet forwarding schemes and integrates with existing Fibre Channel networks and management software. Computers connect to FCoE through CNAs. Function A PCIe function. Each function can be configured by HP-UX as a single device: an FCoE device or a LAN device. HP-UX can configure a dual-ported CNA with as many as 8 PCIe functions (up to four per port) in a Flex-10 environment.
More recent revisions of the PCIe standard support hardware I/O virtualization. Port The physical connection to the network. A CNA may have two physical connections; this configuration is often described as “dual-ported.” CNA overview The CNA is a PCIe device that can be configured by HP-UX as a number of LAN and FCoE devices depending on the system configuration. Most CNAs are dual-ported.
are simple but require too many cumbersome cables and create complexity. Blade switches reduce the number of cables but add more management responsibilities for LAN and SAN administrators. In both cases, multiple people are needed to perform very simple server tasks. Only HP offers the third choice — HP Virtual Connect.
2 servers. With this feature, the server does not need to be powered off to perform any of these operations on a network adapter. The feature is supported with the following network adapters on Superdome 2 servers: • AT094A • AT111A • AT118A Support of this feature requires the following be installed on your Superdome 2 server: • The latest version of the NIC (iocxgbe) and Fibre Channel (fcoc) drivers (B.11.31.1209 or later) • HP-UX operating system B.11.31.
Changed features The iocxgbe driver has been enhanced with performance and stability improvements. Problems fixed in this and recent versions This section describes any problems fixed in this and recent releases of the 10GigEthr-03 product.
Problems fixed in recent releases SR number Description QXCR1001246487 olrad -r/R command does not flag and block attempts to replace an adapter with a different type of adapter When replacing an interface adapter online, an identical adapter must be used as the replacement. The iocxgbe driver should detect and block mismatches but was failing to do so. All replacements were treated as if identical, causing unpredictable results.

• Problems occur when using SNAP (Sub-Network Access Protocol) encapsulation with VLANs. (QXCR1001061473) Severity: Medium SNAP encapsulation enables protocols such as TCP/IP to use an IEEE802.3 SNAP header. This protocol works correctly for non-VLAN devices. For VLAN devices, when a minimum size SNAP packet is received and the VLAN tag is removed, the device incorrectly flags the packet as undersized and discards it. Workaround: None.
The 10GigEthr-03 (iocxgbe) requires the latest firmware for supported devices. For more information, see the latest HP-UX Ethernet Card Support Matrix at: http://www.hp.com/go/10-gigabit-ethernet-docs IMPORTANT: Link problems might be seen with the following iocxgbe adapters: • NC553i Integrated (LOM) FlexFabric adapter • NC552m (product number: 610609–B21) • NC553m (product number: 613431–B21) The problem is caused by a defect in the firmware. Update your firmware to 4.2.401.2212.
