HP XC System Software Installation Guide Version 3.2.1

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 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. Be prepared to supply the information listed in Table 3-2, which is required by the discover
command. You can omit some questions in the discovery process if you provide the related
keyword and value on the discover command line.
