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 Admin Domain restrictions that may be in place. Refer
to chapter 1, "Understanding Admin Domain Restrictions" and Appendix A, "Command Availability"
for details.
