pmpolicy command

This command displays and sets the power management policies for the Lenovo Flex System chassis.

If command syntax is not correctly entered, or if a command fails to run, an error message is returned. See Common errors for a list of error messages that apply to all commands or pmpolicy command errors for a list of error messages that are specific to the pmpolicy command.

Table 1. pmpolicy command.

The command table is a multi-row, four-column table where each row describes a CMM CLI command option: column one lists command function, column two provides a detailed command description, column three shows command-option syntax, and column four lists valid command targets.
Function What it does Command Target (see paths in Command targets)
Display current power management policy Displays the current power management policy. pmpolicy
Lenovo Flex System chassis:
  • system
Display current and available power management policies Displays both the current and available power management policies. pmpolicy pd
Lenovo Flex System chassis:
  • system
Set power management policy Set power management policy. pmpolicy -pm policy

or

pmpolicy pd -pm policy

where policy is:

  • acred (ac power source redundancy policy)
  • acredov (ac power source redundancy policy, with compute node throttling)
  • redwoperf (power supply redundancy, no compute node oversubscription)
  • redwperf (power supply redundancy with compute node power throttling)
  • nonred (no power management policy)
This command can only be run by users who have one or more of the following command authorities:
  • Supervisor
  • Chassis configuration
See Commands and user authority for additional information.
Lenovo Flex System chassis:
  • system

Example:

To view the current power management policy, while the primary CMM in bay 1 is set as the persistent command environment, at the system:mm[1]> prompt, type

pmpolicy -T system

The following example shows the output generated by this command.

system:mm[1]> pmpolicy -T system

Power Domain
--------------

Power Management Policy:
        Basic Power Management (nonred)
Description:
        Total allowed power is higher than other policies and is limited only
        by the total power capacity of all the Power Modules up to the
        maximum of chassis power rating. This is the least conservative
        approach, since it does not provide any protection for power source
        or Power Module failure. If any single power supply fails, blade
        and/or chassis operation may be affected.
Power Supply Failure Limit:       0
Maximum Power Limit (Watts):   5490
Your Estimated Utilization:      20%

NOTE:
 Power Supply Failure Limit: This is the maximum number of power supplies
                             that can fail while still guaranteeing the
                             operation of the domain in the selected policy.
 Your Estimated Utilization: The estimated utilization is based on the maximum
                             power limit allowed in this policy and the current
                             aggregated power in use of all components in the
                             domain.
