pmpolicy command

This command displays and sets the power management policies for the BladeCenter unit.

Table 1. pmpolicy command
Function	What it does	Command	Valid targets
Display power management policy	Displays the current power management policy for all domains.	`pmpolicy`	`-T system`
Display power management policy for a BladeCenter S unit	Displays both the current and available power management policies for a BladeCenter S unit, that has a single power domain.	`pmpolicy` domain where domain is `pd`	`-T system`
Display power management policy for domain	Displays both the current and available power management policies for the specified power domain in a BladeCenter unit that supports two power domains.	`pmpolicy` domain where domain is: `pd1` (power domain 1) `pd2` (power domain 2)	`-T system`
Set power management policy for domain	Set power management policy for specified power domain.	`pmpolicy` domain `-pm` policy where domain is: `pd1` (power domain 1) `pd2` (power domain 2) where policy is: `acred` (ac power source redundancy policy - BladeCenter S units only) `acredov` (ac power source redundancy policy, with blade throttling - BladeCenter S units only) `redwoperf` (power module redundancy, no oversubscription) `redwperf` (power module redundancy with 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.	`-T system`

Example:

To view the current policy and the available policies for a power domain 1, while the BladeCenter unit is set as the persistent command environment, at the system> prompt, type

pmpolicy pd1

The following example shows the output generated by this command.

               system> pmpolicy pd1

Power Domain 1
--------------

*** Current Policy ***

Power Management Policy:
        Power Module Redundancy with Blade Throttling Allowed (redwperf)
Description:
        Very similar to Power Module Redundancy. This policy allows you to
        draw more total power; however, capable blades may be allowed to
        throttle down if one Power Module fails.
Power Supply Failure Limit:       1
Maximum Power Limit (Watts):   3380
Your Estimated Utilization:       5%

*** Available Policies ***

Power Management Policy:
        Power Module Redundancy (redwoperf)
Description:
        Intended for a single AC power source into the chassis where each
        Power Module is on its own dedicated circuit. Total allowed power
        draw is limited to one less than the number of Power Modules when
        more than one Power Module is present. One Power Module can fail
        without affecting blade operation. Multiple Power Module failures can
        cause the chassis to power off. Note that some blades may not be
        allowed to power on if doing so would exceed the policy power limit.
Power Supply Failure Limit:       1
Maximum Power Limit (Watts):   2880
Your Estimated Utilization:       6%

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 AC 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):   3520
Your Estimated Utilization:       5%

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.
