Where to Get More Fast Ethernet Information
For customers with support contracts, further help with solving common Fast Ethernet
networking problems is available at the HP IT Resource Center at
http://www.itrc.hp.com/. Once you have logged in, click on “Search” and then search
the Technical Documents for the following terms (in boldface):
• software locator -- to determine where to find the latest HP-UX -based network or
I/O card software.
• driver locator -- to determine which driver to use with a network or I/O card.
• speed duplex autonegotiation -- to set correct speed, duplex, and autonegotiation
on LAN cards and switches. The latest document is called “Speed and
autonegotiation on network card and switch must match.”
• 100BaseT FAQs --to get answers to frequently asked questions involving LAN card
configuration, drivers, and patches.
Combining Pre-HP-UX 11i Configuration Files
In HP-UX 11i, the drivers for PCI and HSC-based Fast Ethernet networking are
consolidated into one driver called btlan, which is pre-installed as part of the kernel.
The configuration files used by these networking drivers in HP-UX 10.20 and
11.0—hpbtlanconf (btlan), hpbase100conf (btlan3), hpgsc100conf (btlan4),
hppci100conf (btlan5) and hpsppci100conf (btlan6), which are in the
/etc/rc.config.d directory—are merged into one file.
IMPORTANT The configuration files used by the PCI and HSC-based Fast Ethernet networking
drivers must be combined, either by use of a script or manually, into one configuration
file before upgrading to HP-UX 11i.
Merging must be done before updating because the interface used to recognize the host
might be PCI or HSC-based Fast Ethernet. One of these interfaces could have been
configured in a pre-update configuration file, which would have to be maintained for the
update to proceed (the link-up is needed during product configuration).
Merging with the BTLAN.100 Script
When you run the pre-update script BTLAN.100,the configuration files used by the PCI
and HSC-based Fast Ethernet networking drivers are merged into one file called
hpbtlanconf.
Once the BTLAN.100 script creates the merged configuration file, it is placed temporarily
in the /var/adm/sw/save_custom/UNIFIED_MER directory, and the original
configuration files are saved with the extension .obsolete. During the consolidated
btlan driver installation, the merged configuration file is then moved to the
/etc/rc.config.d directory as hpbtlanconf.
