HP XC System Software Installation Guide Version 4.0

Table 6-1 Information Required by the cluster_config Utility (continued)
Description and User ActionItem
If you installed SVA or optional remote graphics software,
1
you are prompted to
supply the following information:
• Whether the visualization nodes (the workstations) have a KVM attached
• The host names for display nodes, that is, the nodes that have monitors connected
to them
• Remote graphics software configuration information:
— The host names of the remote graphics nodes. You must configure external
connections on these nodes.
— Whether you want to use RGS sender on the head node. Doing so enables the
head node to display remote nodes (for HP RGS only).
— Whether you want to use RGS Receiver Version 3.0 to connect the system (for
HP RGS only).
Answering yes means that multiple ports are opened on the firewall.
Answering no opens a single port on the firewall.
The current version of HP RGS is Version 4.n. Version 4.n receivers require a
single port opened in the firewall. If you choose to continue using previously
installed HP RGS Version 3.0 receivers, multiple ports are opened in the
firewall. You can use only Version 4.n receivers or a mix of Version 4.n and
Version 3.0 receivers.
For more information about HP RGS and its use of firewalls, see the SVA System
Administration Guide .
SVA and remote graphics
software configuration
If you assign the ldap_server role to a node, you are prompted to specify
Lightweight Directory Access Protocol (LDAP) configuration information.
You will specify one server to be the LDAP master server and specify one or more
nodes to be LDAP replication servers. HP recommends configuring two LDAP
replication servers.
LDAP configuration
The LDAP master server can be a server that is already configured independent of
and external to the HP XC system, or you can specify the internal node assigned
with the ldap_server role to be the LDAP master server.
You are prompted to supply the following LDAP configuration information:
• IP address of the LDAP master server if you are using a server that is external to
the HP XC system. This server must be running a Linux OS.
• Host name of the LDAP master server if you are using a server that is internal to
the HP XC system.
• Host name of the internal replication server or servers. HP recommends two
internal replication servers.
• Base domain name (DN) of the LDAP database, which is the top level of the LDAP
directory tree. If you are using an external master server, your entry must match
the existing setting on the master server. If you are using an internal XC node as
the master server, this is where you define the directory tree settings.
For example, the following entries set the top level of the tree, the domain name,
example.com:
Enter the LDAP base [o=xc] : dc=example dc=com
