HP XC System Software Installation Guide Version 3.1

used; the administration network and the interconnect share the same ports and switches. All
other interconnect types (Myrinet, InfiniBand, and QsNet
II
) are discovered automatically based
on the interconnect found on the head node; specific command options are not necessary for
those interconnect types.
• HP recommends that you include the --verbose option because it provides useful feedback
and enables you to follow the discovery process.
• Table 3-2 (page 47) and discover(8) contain information about additional keywords you can add
to the command line to bypass some of the questions that will be asked during the discovery
process. Use of these keywords is optional.
• If you encounter problems during the discovery process, see “Troubleshoot the Discovery Process”
(page 189) for troubleshooting guidelines.
• The discover command does not properly discover HP ProLiant DL140 and DL145 servers
until the password is set. Running the discover command now determines the IP address of
the console ports so you can use the telnet command to access the console ports and set the
password. This process is described in “Modify the Default Password for HP ProLiant DL140
and DL145 Hardware Models” (page 57).
5. Follow along with the command output. The sample output shown here was created by using the
--verbose option on a small HP XC system with six HP ProLiant servers (Opteron architecture).
The output you see will be different. The information you supply depends on whether or not you
entered additional keywords on the command line.
NOTE: Table 3-2 (page 47) describes each prompt and provides information to help you with your
answers.
