HP XC System Software Release Notes for Version 3.2.1

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:
1. Unload the tg3 and e1000 drivers:
# rmmod e1000
# rmmod tg3
2. 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
3. Save your changes and exit the text editor.
4. 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.
5. If you made changes, save your changes and exit each file.
6. Reload the modules:
# modprobe tg3
# modprobe e1000
7. Follow the instructions in the HP XC System Software Installation Guide to complete the cluster
configuration process (beginning with the cluster_prep command).
5.3 Notes that Apply to the Discover Process
The notes in this section apply to the discover utility.
5.3.1 Discovery of HP ProLiant DL145 G3 Nodes Fails When Graphics Cards Are
Present
When an HP ProLiant DL145 G3 node contains a graphics card, the nodes often fail to PXE boot.
Even when the BIOS boot settings are configured to include a PXE boot, these settings are often
reset to the factory defaults when the BIOS restarts after saving the changes. This action causes
the discovery and imaging processes to fail.
Follow this procedure to work around the discovery failure:
1. Begin the discovery process as usual by issuing the appropriate discover command.
2. When the discovery process turns on power to the nodes of the cluster, manually turn off
the DL145 G3 servers that contain graphics cards.
3. Manually turn on power to each DL145 G3 server one at a time, and use the cluster’s console
to force each node to PXE boot. Do this by pressing the F12 key at the appropriate time
during the BIOS start up.
After you complete this task for each DL145 G3 server containing a graphics card, the discovery
process continues and completes successfully.
The work around for the imaging failure on these servers is described in “ HP ProLiant DL145
G3 Node Imaging Fails When Graphics Cards Are Present” (page 26), which is the appropriate
place to perform the task.
