HP Insight Cluster Management Utility v7.2 User Guide

To select a terminal emulator other than the default:
1. Edit /opt/cmu/etc/cmuserver.conf.
2. Six blocks of variable names begin with CMU_REMOTE_TERMINAL. Uncomment the full block
of variables for the preferred terminal emulator.
3. Verify all variables for other terminal emulators are commented out.
4. Restart cmuserver:
# /etc/init.d/cmu restart
7.4 Management card connection
This menu is only available when one node is selected. A telnet or secure shell session is launched
to the management card of the selected node. The management card must be properly configured
when HP Insight CMU is installed. If the node does not have a management card, then this menu
is disabled. By default, the session is embedded in an x term window. If you prefer, other terminal
emulators can be used. For more information about the secure shell connection, see “SSH
connection” (page 118).
7.5 Virtual serial port connection
This option is only available when one node is selected. A secure shell session is launched to the
management card of the selected node. Then the appropriate command is automatically issued to
open a virtual serial port on the management card.
7.6 Shutdown
This action is available when one or more nodes are selected. This task enables a system
administrator to issue the shutdown command on selected nodes. The shutdown command can be
performed immediately by default or delayed for a specified time between 1 to 60 minutes. The
administrator can also send a message to the users on the selected nodes by filling in the message
box.

IMPORTANT: Several ProLiant and SMP servers do not support Advanced Power Management
APM. If the nodes are not linked to a management card, then do not use the shutdown command.
Otherwise, the nodes might hang and require a manual shutdown. Use the reboot command
instead.
The shutdown command is performed on nodes using rsh or ssh. On the compute node, permission
must be given to perform commands as superuser or root from the management node. Otherwise,
the shutdown command does not work properly.
7.7 Power off
When one or more nodes are selected, this task enables you to power off the nodes that have a
management card. Nodes to be powered off must have the same management card password.
IMPORTANT: You must use the shutdown command before powering off, or the file systems might
be damaged.
