HP XC System Software Installation Guide Version 3.0

• Partitions the local disk. By default, the first disk is used because disks other than the first disk are not
supported due to restrictions in the image replication environment for this release.
• Creates file systems.
• Downloads the golden image.
• Installs the appropriate boot loader.
When the automatic installation process completes, each node is rebooted and continues its configuration
process, eventually ending with the login prompt.
System Configuration and Imaging Log Files
A record of the configuration process is stored in the /var/log/nconfig.log file.
Logging of the system imaging process is stored in the following files:
• /hptc_cluster/adm/logs/imaging.log
• /var/log/systemimager/rsyncd
• /hptc_cluster/adm/logs/startsys.log
The /hptc_cluster/adm/logs/imaging.log file contains log information produced during the imaging
and node configuration processes. You can use the information in this file to diagnose imaging issues, such
as nodes not booting correctly or failing during the imaging operation. The nconfigure portion of the log
file provides useful information during the first boot after a node has been imaged. If a node configuration
fails, the node is put into single-user mode with network access. The node is not allowed to join the cluster
without user intervention. The node or nodes that are put into single-user mode are listed in the imaging.log
file.
Two system services based on syslog-ng log the UDP based information sent by each client during
installation and the node configuration phase (nconfig). The hptc-ire-serverlog service runs persistently
on the imaging server. It is responsible for accepting UDP messages from the imaging client and from the
hptc-ire-clientlog service running when a node is running through its nconfig phase. The
hptc-ire-clientlog service is managed by autoinstall and the nconfig process. It is only started during
these processes and turned off after the processes have been completed.
The rsync log daemon is responsible for logging start and completion time stamps for imaging and golden
image updates in the /var/log/systemimager/rsyncd file. The information is sent through TCP for
reliability. This is a required service because imaging completion timestamps are used to generate the per
node entries in the /tftpboot/pxelinux.cfg file that denote a system has imaged successfully.
Task 1: Prepare for the System Configuration
• You must know where you stored the XC.lic license key file because you will copy or move it to the
head node.
• Be prepared to supply the information listed in Table 4-1 during the discovery process, which is
documented in “Task 4: Run the discover Command to Discover System Components” (page 41), and
the system configuration process, which is documented in “Task 6: Run the cluster_config Utility to
Configure the System” (page 51).
You can bypass some questions in the discovery process if you provide the related keyword and value
on the discover command line.
