3. Create a new module dependency list, system.map:
# depmod -a
3.6 Task 5: Run the discover Command to Discover System Components
The next step in the configuration process is the discovery of all system components. In addition to
configuring the system topology by discovering all hardware components, the discover command also
configures the administration network and interconnect and populates the configuration and management
database (CMDB).
Important Note About HP Server Blades and Enclosures:
The discovery process differs if the hardware configuration contains HP server blades and enclosures.
See the HP XC Systems With HP Server Blades and Enclosures HowTo for instructions about how to run the
discovery process with the --enclosurebased option for HP server blades and enclosures:

1. Begin this procedure as the root user on the head node.
2. Capture command output into a file; this step is optional, but HP recommends it:
# script your_filename
3. Change to the configuration directory:
# cd /opt/hptc/config/sbin
4. Start the automatic discovery of all network components in the system:
# ./discover --system [--super] [--oldmp] [--outfile file_name] \
[--ic=AdminNet] [--verbose]
Notes About the discover Command Line:
• The --super option is required for large-scale systems (systems with up to 1024 compute nodes)
with a hardware configuration that consists of a Super Root Switch into which multiple Root
Administration Switches are connected.
• The --oldmp option is required on HP Integrity servers (such as the rx8620) if their management
processors (MPs) have statically set IP addresses and are not configured to use DHCP. The
--oldmp option is no longer required if the HP Integrity server has been upgraded with MP
firmware Version 3.15 or newer.
Do not include the --oldmp option on the command line for HP ProLiant nodes because that
hardware family uses iLO and LO-100i as their console port management devices and uses DHCP
to obtain their IP addresses.
• Use the --outfile file_name option to save a copy of the HP XC system information that
is written to the configuration and management database. You must supply an existing file name
on the head node. Saving this information optional, but it enables you to use the --infile
file_name option if it becomes necessary to restore the HP XC system to the point in the
installation just after the discover command was run but before the cluster_config utility
is run.
• Use the --ic=AdminNet option only if you are configuring the interconnect on the administration
network. When the interconnect is configured on the administration network, a single LAN is
