Example 3 with PowerOffState

use of com.emc.storageos.coordinator.client.model.PowerOffState in project coprhd-controller by CoprHD.

the class ControlService method powerOffCluster.

/**
 * This method will set the target poweroff state to PowerOffState.State.START
 * If UpgradeManager sees the target poweroff state is not NONE,
 * node will start to sync with each other's poweroff state until they agree to power off.
 * Node's poweroff state will change from NOTICED to ACKNOWLEDGED. During the process, all nodes
 * are checked to see each other's state until they can move to next state.
 * After all nodes move to ACKNOWLEDGED state, they move to POWEROFF state,
 * in which, they are free to power off
