Optional: Troubleshooting a Fast Ethernet
Migration to HP-UX 11i
The following information is applicable only if your Fast Ethernet update
to HP-UX 11i fails.
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 are automatically updated as part of the process of
migrating to HP-UX 11i.
If the update process fails, the PCI and HSC pre-update configuration
files have to be merged manually as explained further in the following
paragraphs.
How the Automatic Merge Works Using the
BTLAN.100 Script
During an update, a configuration script called BTLAN.100,
automatically merges HSC and PCI pre-11i Fast Ethernet configuration
files 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.
