powerOffListShow

Displays the order in which slots are powered off.

SYNOPSIS powerofflistshow

DESCRIPTION Use this command to display the order in which the physical slots are powered off.

Whenever a power supply goes out of service or a field-replaceable unit (FRU) is inserted, the system's

available power is compared to the system's required power to determine if there is enough power to

operate. If less than the required power is available, the power-off list is processed, until there is

sufficient power for the system to operate.

If the system's power supply drops abruptly to insufficient levels, the power-off list cannot be processed.

The sudden lack of power causes the CP board processors to cease executing the firmware.

For example, if only one power supply is available to power a fully loaded system and the power supply

is removed from the chassis, all system operations terminate immediately, and the power-off list cannot

be processed. However, if the system is running on two power supplies (this is not recommended) and

one goes into a predicted fail state (in which the power supply is still supplying power), the power-off list

is processed as described.

NOTES Command output may vary depending on the hardware platform.

Control processor (CP) blades are not included in the power-off list.

The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in

place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for

details.
