This task uses PDomain_0 as an example. You must have the admin role (a) to complete this task.

View the current power allocation for the host.

SPARC M8 and M7 servers show similar output with watt variance due to power supply differences.

Activate the power allocation feature.
You must enable the power allocation feature before you can set a new power limit.
```
-> set /Servers/PDomains/PDomain_0/SP/powermgmt/budget activation_state=enabled
Set 'activation_state' to 'enabled'

->
```
Set the power limit.
You can set the power limit to be between the minimum power limit, which is the value of the min_powerlimit property, and the maximum power limit, which is the value of the powerlimit property. You can express the power limit value in either watts, wattsw, or as a percentage (percent%) between the valid range, as in the following example.
```
-> set /Servers/PDomains/PDomain_0/SP/powermgmt/budget pendingpowerlimit=75%
Set 'pendingpowerlimit' to '75%' [75 (%)]

->
```
If needed, set the time limit.
The time limit is the grace period during which the power limit is allowed to be exceeded after it is initially achieved. You can set this value to default (30 seconds) or a value in seconds (0–99999).
```
-> set /Servers/PDomains/PDomain_0/SP/powermgmt/budget pendingtimelimit=60
Set 'pendingtimelimit' to '60'

->
```
If needed, set the violation action.
This property instructs the SP what to do if the time limit property is exceeded. The possible values are none or hardpoweroff.
```
-> set /Servers/PDomains/PDomain_0/SP/powermgmt/budget pendingviolation_actions=hardpoweroff
Set 'pendingviolation_actions' to 'hardpoweroff'

->
```

Commit the changes.

You must perform this step for the changes to take effect.

-> set /Servers/PDomains/PDomain_0/SP/powermgmt/budget commitpending=true
Set 'commitpending' to 'true'

->

Verify that the changes were made.

-> show /Servers/PDomains/PDomain_0/SP/powermgmt/budget
