HP XC System Software Installation Guide Version 3.0

Description and User ActionItem
Enter the number of nodes that are workstations, that is, nodes that do not have console ports.
There is no default response. Enter 0 (zero) if your system does not contain workstations.
You will not be prompted for this information if you are discovering a multi-region, large-scale
system.
You can include the ws= keyword on the discover command line to bypass this question during
the discovery process.

workstations
Look on the back panel of the ProCurve Root Administration Switch near the 9-pin console port
and write down the MAC address. Use the switch management serial console with a terminal
connected if you cannot read the MAC address.
See “ProCurve Switches Do Not Obtain Their IP Addresses” (page 142), which describes how
you can identify which switch is the Root Administration Switch or the Super Root Switch (for a
multi-region, large-scale system).
You can include the switchmac= keyword on the discover command line to bypass this
question during the discovery process.
MAC address of the root
administration switch or super root
switch
Enter the common administrator password for the ProCurve switches if it was previously defined;
setting this password was an optional task during the hardware preparation phase.
Press Enter if you did not set this password when you prepared the hardware.
You can include the switchpw= keyword and value on the discover command line to bypass
this question during the discovery process.
Administrator password for the
ProCurve switch
Enter the previously defined common user name and password that you set for the console
management devices (that is, the MP, iLO and LO-100i devices) when you prepared the hardware.
This task was performed on all server models except the HP ProLiant DL140 G2 and DL145 G2
servers.
All console management ports on the system should have been configured with the same user
name and password; otherwise, the discovery process will not succeed.
You can include the cpuser= and consolepw= keywords and values on the discover
command line to bypass these questions during the discovery process.
User name and password for the
console port devices
For Itanium-based systems only, you are asked to supply the number of nodes that are plugged
into the Root Administration Switch.

For Itanium-based systems only, you are asked to supply the number of nodes plugged into
application cabinets.

Information Requested by the cluster_config Utility
You are prompted to supply the number of NFS daemons to be run on the head node and on
any other NFS server within the system to support the number of NFS clients in the system. A
default is provided based on the number of nodes in your system.
Number of NFS daemons
A text-based menu is displayed which enables you to change the default node role assignments
and to add or remove an external Ethernet connection to any node.
See Chapter 8 (page 91) for node role definitions and for more information about using the
menu.
Node role assignments and
Ethernet connections
One node in an HP XC system acts as an NTP server for all other nodes. By default, this is the
head node. All other nodes are NTP clients of this server, which is known as the internal NTP
server. All nodes in the system are synchronized to the head node.
You have the option to specify up to four external time servers or to use the default NTP server
on the head node.
NTP server configuration
For systems with QsNet
II
interconnects, you are asked to supply the type of network. The network
type reflects the maximum number of ports the fabric topology can support, and it is used to
create the qsnet diagnostics database. See Appendix G (page 125) for information about how
to determine the QsNet
II
network type.

network type
If you modified the default role assignments and assigned a login role to one or more nodes,
you are prompted to enter an LVS alias. This is the name that users will use to log in to the HP
XC system.
LVS alias
You have the option to enable Web access to the Nagios monitoring application. HP recommends
that you enable Web access because it is the only mechanism with which you can view the data
collected by Nagios.
You will have to supply a password for the Nagios admin user. This password does not have to
match any other password you previously provided.
