Table 3-1 Information Required by the cluster_prep Command
Description and User ActionItem
During the system discovery process, each node is automatically assigned an
internal name. This name is based on a prefix defined by you. The default node
prefix is the letter n. All node names consist of the prefix and a number based
on the node's topographical location in the system. You have the option to change
this default, perhaps to differentiate the nodes from another system or to
customize node names according to your corporate policies.
Choose a node prefix that adheres to these guidelines:
• The node name consists of a maximum of six alphanumeric characters:
— The lowercase letters a through z
— The uppercase letters A through Z
— The numbers 0 (zero) through 9
• The first and last characters in the prefix must be alphabetic.
• Hyphens (-) and periods (.) are not permitted.
By default, nh is assigned as the head node alias, regardless of the node prefix.
Node name prefix
Enter the maximum number of nodes you expect to have in the system, taking
future expansion into consideration.
For flexibility, consider entering the maximum number of nodes allowed by the
interconnect. For instance, the interconnect might allow a maximum of 128 nodes,
but the system contains only 64 nodes. In this case, enter the number 128 when
prompted.
If the hardware configuration consists of HP server blades, you are not prompted
to supply the maximum number of nodes in the system.
Maximum number of nodes
in the system
Define and set a password to protect the configuration and management database.
Make this password different from the root password.
You are prompted for this password any time you log into the configuration and
management database.
See “Password Guidelines” (page 185) if you need recommendations on choosing
strong passwords.
Database administrator's

You are prompted to configure an external Ethernet device on the head node.
Doing so connects the node directly to the public network. The most likely
Ethernet device to use as the external network connection is presented to you
by default. You can use this value or provide a different value.
If you need more information to verify that you are selecting the correct Ethernet
device on the head node, open a new terminal window and use the ethtool
ethernet-device-name command to provide more information about the
Ethernet devices on the node.
External Ethernet connection
on the head node
Provide the IP address for the head node's Ethernet connection to the external
network. This is the address assigned by your site's network administrator. The
IP address must be in your site's Domain Name Service (DNS) configuration.
Enter the address in dotted decimal format n.n.n.n, where n is the decimal
value in the range 0 to 255 and is the decimal value of an 8-bit segment of the
address.
IP address for the external
network connection
Provide the network mask (netmask) for the external network on the head node.
The network mask is used for each of the addresses in the address range and is
specified in dotted-decimal format (for example, 255.255.252.0).
