HP XC System Software Installation Guide Version 4.0

Table 3-1 Information Required by the cluster_prep Command (continued)
Description and User ActionItem
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).
Network mask
Provide the IPv6 address of the head node's Ethernet connection to the external
network, if applicable. Specifying this address is optional and is intended for sites
that use IPv6 addresses for the rest of the network.
Enter the IPv6 address in the format x:x:x:x:x:x:x:x/n where x consists of one
to four hexadecimal digits that represent a 16-bit segment of the address, and n
represents the prefix length (for example,
2001:0db8:0000:0000:0000::1428:57ab/32). The prefix length represents
the netmask parameter equivalent and can be in the range of 1 to 128.
You can omit leading zeros within each hexadecimal field and use two colons (::) to
indicate multiple 16-bit groups of zeros.
If a value is already present in this field, enter left and right brackets [ ] to erase it
IPv6 address
Provide the network gateway IP address for your site.
The network gateway is the next-hop router the system uses to direct any traffic to
a host that is not directly on your site's local network. This address is specified as a
dotted-decimal address (for example, 192.0.2.51) rather than a name.
Gateway IP address
Enter 9000 to enable jumbo frames on external Ethernet interfaces or leave this field
blank to use the system default (1500).
Jumbo frames sets the maximum transmission unit (MTU) to 9000 bytes for improved
efficiency and performance with bulk data transfer. The MTU must match on the
other end of the connection.
If a value is already present in this field, enter left and right brackets [ ] to erase it
MTU (jumbo frames)
Provide the IP address for your site's DNS server. This address is specified in
dotted-decimal format (for example, 192.0.2.50).
IP address for the DNS name
server
Provide a list of name server domains to search to resolve host names when the
following prompt appears:
Provide one or more DNS domains to use for search paths
or press the Enter key to accept the default response.
Enter one domain name on a line, and after the last domain
name, enter a period (.) on a line by itself and press the
Enter key.
Search path:
The domain name is typically in the form my-domain.com (assuming that the head
node is intended to be HeadNodeName.my-domain.com). Enter the search entry
in the following format:
DomainName.something[.something....]
The search entry can have from one to six DomainName variables. The DomainName
variable is the name of a domain to be included in the search list. The first
DomainName variable is interpreted as the default domain name.
Search path
3.3 Changing the Default IP Address Base (Optional)
You might have to change the default IP address base of the XC private networks if the default
values conflict with another IP address base at your site. The address base is stored in a .ini
