7. Follow the instructions in the HP XC System Software Installation Guide to complete the cluster
configuration process (beginning with the cluster_prep command).
5.2 Notes That Apply To The Discover Process
The notes in this section apply to the discover utility.
5.2.1 Discovery of HP ProLiant DL140 G3 and DL145 G3 Nodes Fails When
Graphics Cards Are Present
When an HP ProLiant DL140 G3 or 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 DL140 G3 and DL145 G3 servers that contain graphics cards.
3. Manually turn on power to each DL140 G3 and 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 DL140 G3 and 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 DL140
G3 and DL145 G3 Node Imaging Fails When Graphics Cards Are Present” (page 27), which is
the appropriate place to perform the task.
5.3 Notes That Apply Before You Invoke The cluster_config Utility
Read the notes in this section before you invoke the cluster_config utility.
5.3.1 Adhere To Role Assignment Guidelines for Improved Availability
When you are configuring services for improved availability, you must adhere to the role
assignment guidelines in Table 1-2 in the HP XC System Software Installation Guide. Role
assignments for a traditional HP XC system without improved availability of services is slightly
different, thus it is important that you follow the guidelines in Table 1-2.
5.4 Benign Message From C52xcgraph During cluster_config
