powerOffListSet
powerOffListSet
Sets the order in which slots are powered off.
Synopsis powerofflistset
Description Use this command to modify the order in which slots are powered off. This command displays the current order,
and then prompts you interactively to confirm or modify the power-off position for each slot.
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.
The power-off list does not affect the order, in which slots are powered on. On power-on or when an additional
power supply is added, slots are processed sequentially, starting at slot 1.
Notes CP blade slots and Core blade slots are not included in the power-off list.
Command output may vary depending on the hardware platform.
Some FRUs may use significant power, but cannot be powered off by the software. For example a missing blower
FRU may change the power computation enough to affect how many slot blades can be powered up.
The execution of this command is subject to Virtual Fabric restrictions that may be in place. Refer to "Using Fabric
OS Commands" and "Command Availability" for details.
