Fast Ethernet Network Driver btlan
new at 11i
original release
Starting with HP-UX 11i v1, all of the previous PCI and HSC Fast Ethernet network
drivers are combined into a single driver called btlan. Also, the new btlan driver is
always-installed as part of the kernel. This simplifies installation and upgrade.
For HP-UX 11i v1, the PCI and HSC-based Fast Ethernet network cards previously
supported by HP-UX 10.20 and 11.0 drivers btlan, btlan3, btlan4, btlan5 and btlan6
are now supported on HP-UX 11i v1 by the btlan driver.
Impact
The btlan driver works seamlessly with existing HP LAN link administrative
commands such as lanadmin, lanscan, linkloop, and NetTL.
The 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 networking and mass storage cards on various systems including L-Class, N-Class
and Superdome servers.
IMPORTANT If you have HP-UX 10.20 and 11.00-based scripts that specifically refer to btlan3,
btlan4, btlan5 or btlan6, and if you migrate to HP-UX 11i v1, you need to change those
scripts to refer to btlan.
You 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)
