14.8.3.3 Voltaire InfiniBand Switch Administrative Password
The documentation that came with your model of the Voltaire InfiniBand switch describes how
to set the administrative password.
Generally, you change the Voltaire Infiniband switch administrative password by logging in to
the switch as admin and using its command interface as in the following example:
# telnet IRON00
IR0N00 login: admin
Password:
Welcome to Voltaire Switch IR0N00
connecting
IR0N00> enable
password:
IR0N00# ? pass
password update [admin, enable]password update [admin, enable]
IR0N00# password update admin
Insert new (up to 8 characters)password:
Please retype new password:
OK
IR0N00# password update enable
Insert new (up to 8 characters)password:
Please retype new password:
OK
IR0N00#
Also, enter the following command to set up ssh as root on the switch, which will enable you
to access the root switch without a password:
# cat /root/.ssh/id_dsa.pub | ssh IR0N00 cat '>>' /.ssh/authorized_keys
Accessing the root switch without a password is necessary for the proper operation of the
ip_prodmode_mon monitoring utility and the sys_check infiniband component.
Repeat these steps for each switch controller card, for example, for IRON00, IRON01, and so on.
14.8.3.4 Voltaire 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 command 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
