Always-Installed Network Drivers

The changes to the 100BASE-T driver, btlan, in the HP-UX 11i v2 release are to provide support for interrupt migration and OLAR on Itanium-based platforms.

Interrupt migration provides the capability for the user to move device interrupts amongst processors allowing the balancing of the system's interrupt load, thereby improving performance.

The OLAR feature enables the addition and/or replacement of 100Base-T adapter cards without shutting down the system. For more information, see “On-line Addition and Replacement (OLAR) of I/O Adapters”.

There are no compatibility issues.

There are no performance issues.

For information on installing, configuring, advanced features, and troubleshooting the 100Base-T Ethernet adapter, see these documents on the Instant Information CD and at http://www.docs.hp.com/hpux/netcom/index.html#10/100Base-TX/9000:

Not applicable.

In the HP-UX 11i v2 release, the GigEther-01 product (which supports the Gigabit Ethernet adapters: A4926A, A4929A, A6794A, A6825A, A6847A, and A6865A) is supported and the IEther-00 product, supporting the zx2000 core, is introduced. The drivers, igelan and iether, are available in the GigEther-01 and IEther-00 software bundles respectively.

Additionally, 1024~9000 Maximum Transmission Unit (MTU) support for both adapters is supported in HP-UX 11i v2 to enable you to operate at any MTU from 1024 to 9000, whereas previously only 1500 or 9000 was allowed.

There are no impacts.

Earlier versions of lanscan will not work in HP-UX 11i v2, as they depend on the lanscan shared library which has been obsoleted in the current version of the driver products.

There are no performance issues.

For information on installing, configuring, and troubleshooting Gigabit Ethernet, see PCI 1000Base-T and 1000Base-SX Quick Installation and Configuration Guide and related documents. This documentation is available in the /opt/networkdocs directory on your system and at http://www.docs.hp.com.

For advanced features and detailed information on troubleshooting, see Using PCI 1000Base-T and HSC/PCI 1000Base-SX (Gigabit Ethernet). This document is available on the Instant Information DVD and at http://www.docs.hp.com.

For the GigEther-01 and IEther-00 software bundles, the lanscan shared library and catalog file have been obsoleted because they are not necessary to the HP-UX 11i v2 lanscan executable.

PCI FDDI has been enhanced to provide the FDDI network connectivity for Itanium-based platforms.

You can now connect to FDDI networks from your Itanium-based system.

Earlier versions of the lanscan and lanadmin binaries do not work on HP-UX 11i v2 because they depend on the lanscan and lanadmin shared libraries.

There are no performance issues.

For further information, see Installing and Administering HP9000 PCI FDDI (product number J3626-90032), available at http://www.docs.hp.com/hpux/netcom/index.html#FDDI/9000.

The lanscan and lanadmin shared libraries and their corresponding catalog files have been obsoleted.
