Changing the power state of a node
To change the power state of a node:
1. Select one or more nodes.
2. The available selections depend on the current state of the selected nodes. Do one of the
following:
• Click Actions→Power off Node (Shutdown) to gracefully exit the running operating system
and power off the node.
• Click Actions→Power off Node (Force) to power off the node when an OS is not installed.
• Click Actions→Power On Node to power on the selected node.
NOTE: When planning to change the power state for multiple selected nodes, HP recommends
that you verify that all the selected nodes have the same current power state before selecting
a power state change from the Actions menu.
Viewing node logs
Node logs provide a record of historical events that have occurred. Events are generated by the
system ROM and include all node-specific events. Log entries can help you diagnose issues or
identify potential issues. Preventative action might help to avoid disruption of service.
To view the Nodes page, from the main menu, select Nodes. The page defaults to an overview of
the first node in the node list, shown on the left side of the page. Select Logs from the View menu
to show the node logs.
The log information available for each node includes the following:
• ID—The event ID number. Events are numbered in the order in which they are generated.
By default, the log is sorted by the ID, with the most recent event at the top.
• Severity—The importance of the detected event.
Possible values include:
◦ Critical—The event indicates a service loss or an imminent service loss. Immediate
attention is needed.
◦ Caution—The event is significant but does not indicate performance degradation.
◦ Informational—The event provides background information.
◦ Unknown—The event severity could not be determined.
• Type—A further descriptor of the nature of the event.
• Created on—For events with a count of 1, this is the date the event first occurred. For events
with a count greater than 1, this is column shows the date the event was last updated.
• Count—The number of times this event has occurred (if supported).
In general, important events generate an event log entry each time they occur. They are not
consolidated into one event log entry.
When less important events are repeated, they are consolidated into one event log entry, the
Count value is updated. Each event type has a specific time interval that determines whether
repeated events are consolidated or a new event is logged.
• Description—The description identifies the component and detailed characteristics of the
recorded event.
