Optional
To remove the server or network device corresponding to a real service
from a cluster, you can enable slow-offline for the real service. After
slow-offline is enabled, the LB device will not assign new services to the
real service and you can remove the server or network device from the
cluster after the original services of the real service are processed.
The slow-offline function can avoid the service interruption caused by
sudden removal of a server or network device.
