HP Insight Cluster Management Utility Management card connection, Virtual serial port connection

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

6.4 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 91).

6.5 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.

6.6 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.

6.7 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.
