246 Troubleshooting and Recovery

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 the CMC and configuring

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

page 175.

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

Budget Status" on page 185.

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 198, "Executing Power Control

Operations on an IOM" on page 199, and "Executing Power Control

Operations on a Server" on page 200.

Viewing Chassis Summaries

The CMC provides rollup overviews of the chassis, primary and standby

CMCs, iKVM, fans, temperature sensors, and I/O modules (IOMs).
