HP XC System Software Release Notes for Version 3.0

The head node console port may be either internally or externally connected to the HP XC system.

Follow the procedure that is appropriate for your system.

5.5.2.1 Setting the BMC/IPMI Password When There is an External Connection to the Head Node

Management Port

When there is an external connection to the head node management port, follow this procedure

to allow access to the head node's management port through the external IP address and

synchronize the management port passwords:

Note:

In the following command line examples, substitute the internal node name of your head node

for the variable headnode (for example, n144) .

1. Use the text editor of your choice to add the following line to the /etc/hosts file:

external-ip-address cp-headnode

See hosts(5) for information on the /etc/hosts file.

2. Enter one of the following commands to use the ipmitool to set the BMC password.

Important:

The command you use to set the management port password differ depending on whether

or not the IPMI password has been configured (that is, if the password is null):

• If the IPMI password has been configured previously, enter the following command:

pdsh -a -x "headnode" 'ipmitool -I lan -P "oldpassword" \

-H cp-$(nodename) user set password 1 newpassword'

• If the IPMI password has never been configured, enter the following command:

pdsh -a -x "headnode" 'ipmitool -I lan -P "" \

-H cp-$(nodename) user set password 1 newpassword'

The default password setting is a null ("").

Note:

Setting the password returns a message similar to the following, which can be ignored:

Close Session command failed

5.5.2.2 Setting the BMC/IPMI Password When There is an Internal Connection to the Head Node

Management Port

If the head node console port is connected internally, use the following ipmitool command

line to synchronize the console management port password throughout the HP XC system:

# pdsh -a 'ipmitool -I lan -P "oldpassword" \

-H cp-$(nodename) user set password 1 newpassword'

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

This note applies only to systems using a Myricom or QsNet

interconnect. Skip this task if your

system uses another interconnect type.

Appendix D 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.
