HP XC System Software Installation Guide Version 3.2.1

NOTE:
Follow this procedure before you run the discover command if you want to locate the
console port of a non-blade head node on the administration network and not on the external
network:
1. Set the IP address for the head node console port to a static IP address that is not
currently in use by the HP XC system. Typically, this address can be 172.31.47.240,
which is the top end of addresses defined for the HP XC switches defined in the
/opt/hptc/config/base_addrV2.ini file.
2. Add the address to the top portion of the /etc/hosts file. The top portion of this file
is reserved for user customizations. Add the entry similar to the following:
172.31.47.240 cp-n0
4. Start the discovery of all network components:
# ./discover --system \
[--super] \
[--oldmp] \
[--outfile file_name] \
[--ic={AdminNet|Ethernet|Infiniband|Myrinet|Quadrics}] \
[--verbose]
Table 3-4 discover Command Options
DescriptionOption
The --super option is required for large-scale systems (systems with up to 1024
compute nodes) when the hardware configuration consists of a Super Root Switch
into which multiple Root Administration Switches are connected.
--super
The --oldmp option is required on HP Integrity servers (such as the rx8620) if
their management processors (MP) 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.
--oldmp
The --outfile file_name option saves a copy of the HP XC system
information that is written to the configuration and management database. The
file name you specify must already exist 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.
--outfile file_name
The --ic={AdminNet|Ethernet|Infiniband|Myrinet|Quadrics}
option specifies the type of interconnect to configure. If you do not specify this
option, the discover utility configures the fastest interface it finds available in
the hardware configuration. Your entries are case sensitive.
When the interconnect is configured on the administration network, a single
LAN is used. The administration network and the interconnect share the same
ports and switches.
All other interconnect types (Myrinet, InfiniBand, and Quadrics) are discovered
automatically based on the interconnect found on the head node. You are not
required to specify these interconnects on the command line.
--ic=
The --verbose option provides useful feedback during the discovery process
that enables you to follow along. HP recommends including it on the command
line.
