First Steps to Troubleshooting a Remote System

The following questions are commonly used to troubleshoot high-level

problems in the managed system:

Is the system powered on or off?

If powered on, is the operating system functioning, crashed, or just frozen?

If powered off, did the power turn off unexpectedly?

Monitoring Power and Executing Power Control

Commands on the Chassis

You can use the Web interface or RACADM to:

• View the system’s current power status.

• Perform an orderly shutdown through the operating system when

rebooting, and power the system on or off.

For information about power management on CMC and configuring power

budget, redundancy, and power control, see "Power Management" on

page 309.

Viewing Power Budget Status

For instructions on viewing power budget status for the chassis, servers,

and PSUs using either the Web interface or RACADM, see "Viewing Power

Consumption Status" on page 332.

Executing a Power Control Operation

For instructions on powering on, powering off, resetting, or power-cycling the

system using the CMC Web interface or RACADM, see "Executing Power

Control Operations on the Chassis" on page 349, "Executing Power Control

Operations on an IOM" on page 350, and "Executing Power Control

Operations on a Server" on page 352.
