HP XC System Software Installation Guide Version 3.1

Table 3-1 Information Required by the cluster_prep Command (continued)
Description and User ActionItem
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 default value is present, 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
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 is displayed:
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. Be prepared to supply the information listed in Table 3-2, which is required by the discover
command. You can bypass some questions in the discovery process if you provide the related keyword
and value on the discover command line.
