HP-UX 11i September 2001 Release Notes

I/0 and Networking Cards

Network Drivers (new at 11i original release)

Chapter 5

NOTE 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.

The conﬁguration ﬁles used by the above 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 — will be merged into one called hpbtlanconf by running the preupdate

script BTLAN.100. The merged conﬁguration ﬁle hpbtlanconf will be used by the

consolidated driver btlan.

Merging must be done before updating, because the interface used to recognize the host

might be PCI/HSC-based Fast Ethernet, which could have been conﬁgured in one of the

conﬁguration ﬁles that has to be maintained for the update to proceed. Since the update

procedure needs the link up during conﬁguration of products.

The merged conﬁguration ﬁle created by the BTLAN.100 script will be placed temporarily

in the /var/adm/sw/save_custom/UNIFIED_MER directory. During the consolidated

btlan driver installation it will be moved to the /etc/rc.config.d directory as

hpbtlanconf.

This script will merge only the above 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 (btlan4) and

corresponding hardware (HSC cards), then the hpgsc100conf conﬁguration ﬁle should

have at least one card conﬁgured in it. During the update process, the original

conﬁguration ﬁles will be saved with the extension .obsolete.

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. When that has been done, restart the

update process.

Manual Merging

Manual merging has to be done prior to the update process in the event of failure of the

update process, as discussed in the previous section. 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].

The ﬁve ﬁles to merge, which may exist in the /etc/rc.config.d directory are:1)

hpbtlanconf (btlan); 2) hpbase100conf (btlan3); 3) hpgsc100conf (btlan4); 4)

hppci100conf (btlan5); and 5) hpsppci100conf (btlan6)

Manual Merging Procedure

1. Find out which of the ﬁve conﬁguration ﬁles as listed above exists in the

/etc/rc.config.d directory.

2. For each of the ﬁles found in Step 1, ﬁnd out if hardware is present by using the

command ioscan -kfC lan. Look at the following list for the mapping between the

driver name and its conﬁguration ﬁle.
