Network Drivers
New Network Driver btlan Always-Installed
new at 11i
original release
The networking driver for HP-UX 11i has been simplified and is now easier to install
and upgrade.
The PCI and HSC-based Fast Ethernet network and I/O cards supported by drivers
btlan, btlan3, btlan4, btlan5 and btlan6 have been combined into a single driver
called btlan. This new driver is always-installed as part of the kernel.
The result is to ease setup or upgrade of the networking and I/O products by eliminating
driver installation and combining multiple drivers into one.
Impact
The btlan driver works seamlessly with existing HP LAN link administrative
commands such as lanadmin, lanscan, linkloop, and NetTL.
The new btlan driver supports the same functions and features as the previous HP-UX
10.20 and 11.0-based drivers. In addition, it also supports the online addition and
replacement of I/O cards on L-Class, N-Class and Superdome servers.
IMPORTANT Although there you will see no impact in most cases, you will if you have scripts that
refer specifically to btlan3, btlan4, btlan5 or btlan6.
You will need to use the new driver name btlan with the following commands:
• what string
For example: what /stand/vmunix | grep btlan
• ioscan
For example: ioscan -kfC lan | grep btlan
You will also see the driver name btlan as the output in:
• the system file /stand/system
• nettlgen.conf and in the file /var/admin/sw/nettl.LOG00
Files Changed
The following files have changed to include the new btlan driver name (most involve
just name changes):
• kernel library is now called /usr/conf/libbtlan.a
• nettl formatter/catalog files (no change except instead of btlan3, btlan4, btlan5,
btlan, or btlan6, it will just refer to btlan)
• debug/q4
