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.
Note that the BTLAN.100 script will only merge the driver-specific configuration files if
the corresponding hardware is present on the system, and if the files have at least one
LAN interface configured. (For example, if the system had the HSC-based Fast Ethernet
networking driver [btlan4] and corresponding hardware [HSC cards], then the
hpgsc100conf configuration file should have at least one card configured in it.)
Manual Merging
If the update process is abandoned because of preupdate script failures (other than
syntax errors in configuration files or a duplicate LAN interface error), then the
configuration files have to be merged manually. Once this has been done, you can then
continue the update process. (Once the update process is restarted, the user should
answer NO (N) at the prompt, Do you want to proceed in merging the
configuration files into one? [Y|N].)
Manual Merging Procedure
1. Find out which of the five configuration files listed below exists in the
/etc/rc.config.d directory.
• hpbtlanconf (btlan)
• hpbase100conf (btlan3)
• hpgsc100conf (btlan4)
