6.8 Boot

When one or more nodes are selected, this task enables you to boot a collection of nodes on their own local disk or over the network. You must select nodes to be booted prior to running this command.

The boot procedure uses the management card of each node. The password for the management card must be entered. Nodes to be booted must have the same management card password.

IMPORTANT: If the nodes are booted, the boot procedure attempts a proper shutdown. If the shutdown fails, then the management card resets which can damage the file system. To avoid this risk, perform a shutdown operation before issuing a boot command.

Figure 48 Boot dialog box

6.9 Reboot

When one or more nodes are selected, this task enables a system administrator to issue the reboot command on selected nodes. The reboot command is 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 logged on selected nodes by filling in the message edit box.

IMPORTANT: The reboot command is performed on nodes using rsh or ssh. On the compute node, permission must be given from the management node to perform commands as superuser or root. Otherwise, the reboot command does not work properly.

6.10 Change UID LED status

When one or more nodes are selected, this task changes the status of the locator LED on selected nodes. If the switch is on, it is turned off and vice versa.

NOTE: This menu is available only if the node has an iLO management card properly registered in the HP Insight CMU database and the system is equipped with a status LED.
