Required Task for Some NIC Adapter Models: Verify Correct
NIC Device Driver Mapping |
 |
On head
nodes installed with dual-fiber NIC server adapter models NC6170 or
NC7170, Ethernet ports might be reordered between the Kickstart kernel
and the subsequent HP XC kernel reboot. Use the procedure
described in this section to correct the mapping if a re-ordering
has occurred.
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:
You must correct this mapping if you find that
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, perform this procedure from a locally-connected
terminal before invoking 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 text editor.
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.
Reload
the modules:
# modprobe tg3
# modprobe e1000 |
Follow the instructions in the HP XC System Software Installation Guide to complete
the cluster configuration process (beginning with the cluster_prep command).
