5.5.4 Change the InfiniBand Switch Root Password

The InfiniBand switches run Linux and have a root password. Occasionally, you might have to

log into the InfiniBand switch as root, so HP recommends that you use the following procedure

to change the default root password on the InfiniBand switches:

1. Use ssh or telnet to log in to the InfiniBand switch as root. The default password is

br6000.

2. Use the passwd to change the root password.

3. Make a backup copy of the cliPassWord.crpt file:

# cp /mnt/jffs/voltaire/config/cliPassWord.crpt \

/mnt/jffs/voltaire/config/cliPassWord.crpt.orig

4. Copy the /etc/shadow file into the cliPassWord.crpt file:

# cp /etc/shadow /mnt/jffs/voltaire/config/cliPassWord.crpt

5.5.5 Save the Contents of the /etc/dhcpd.conf File

This note applies only to systems using a Myrinet® interconnect. Skip this task if the system

uses another interconnect type.

An Appendix in the HP XC System Software Installation Guide instructs you to configure the

interconnect switch line monitoring cards before the system is configured. Part of the procedure

involves adding entries to the /etc/dhcpd.conf file.

The cluster_config utility rewrites the /etc/dhcpd.conf file, and if you edit this file before

invoking the utility, your changes to this file are lost.

Therefore, save your customizations to the /etc/dhcpd.conf file before invoking the

cluster_config utility:

# cp /etc/dhcpd.conf /etc/dhcpd.conf.ORIG

5.5.6 Error Messages for InfiniBand Switch Entries

If the InfiniBand switch entries in the /etc/hosts file contain a trailing space, the

cluster_config utility displays a message similar to the following for each switch:

Executing C52xcgraph gconfigure

sh: line 1: /PortCounters.csv: No such file or directory
