Node evacuation is a process that is required during a hot node repair or a memory upgrade. During the node evacuation process, the Power Hypervisor is used to complete the following tasks.
Move the contents of the memory in the target node to the memory in the other nodes of the system.
Move the programs running on dedicated processors assigned to the partitions, and the programs running on processors assigned to the shared processor pool, from the target node to other nodes on the system.
Lock all the I/O slots that are attached to the target node to prevent the slots from being used during the repair or upgrade.
