Managing Power for Each Platform
This section provides information on various platform power control options provided by the Fabric Manager.
You can use the power control options on a particular platform and not on all platforms at the same time in a given system. For example, in the system if there are three platforms, platform x, platform y, and platform z, then the power control options performed on platform x are applicable only to platform x. You cannot use power control options on all three at the same time.
In general, platforms can be shutdown gracefully or forcefully.
Graceful Shutdown: This is an orderly shutdown of the platform. You can use the Soft Shutdown and Soft Restart options to perform graceful shutdown of the platform. The current state of the operating system is saved during this shutdown.
Forceful Shutdown: This is an unorderly shutdown where the state of the operating system is not saved. You can use the Power Off, Hard Restart, Power Cycle, and Force Dump options to perform forceful shutdown of the platform.
CautionAvoid forceful shutdown unless required. This operation may result in data loss and may also cause s-Par® instances to crash.
Note: Platform power operations are asynchronous and Fabric Manager does not wait until the operation is complete on the platform to report the success or failure of the operation. The Fabric Manager executes the command on the platform which initiates the desired action. You should ensure manually on Fabric Manager user interface that the operation is complete on the platform and retry if required.
This section provides the following information:
The following table provides the summary of different power operations you can perform on partitionable EPP and nonpartitionable EPP when they are powered on.

|---|---|---|
Soft Shutdown | Yes | Yes |
Hard Restart | Yes | Yes |
Soft Restart | Yes | No |
Power Cycle | Yes | Yes |
Force Dump | Yes | Yes |
