Required Task for Some NIC Adapter Models: Correct NIC Device
Driver Mapping |
 |
On
head nodes installed with dual-fiber NIC server adapter models NC6170
or NC7170, Ethernet ports are reordered between the Kickstart kernel
and the subsequent HP XC kernel reboot. At the time of the Kickstart
installation, the fiber ports are identified as eth0 and eth1, and
the onboard ports are identified as eth2 and eth3.
The /etc/modprobe.conf file
is written as follows:
Upon the HP XC kernel reboot, eth0 and eth1 are
the tg3 devices, and eth2 and eth3 are the e1000 devices. To get the
external network connection working, follow this procedure from a
locally-connected terminal before running the cluster_prep utility:
Unload the tg3 and e1000 drivers:
# rmmod e1000
# rmmod tg3 |
Use the text editor of your choice to edit the /etc/modprobe.conf file to correct the mapping of drivers
to devices. The section of this file should look like this when you
are finished:
alias eth0 tg3
alias eth1 tg3
alias eth2 e1000
alias eth3 e1000 |
Save your changes and exit the file.
Use the text editor of your choice to edit the /etc/sysconfig/network-scripts/ifcfg-eth[0,1,2,3] files,
and remove the HWADDR line from each file if it
is present.
If you made changes, save your changes and exit each
file.
Follow the instructions in the HP XC System Software Installation Guide to complete
the cluster configuration process (beginning with the cluster_prep command).
