features:
- Change the port for devices in the ring by adjusting
the port value for services, hosts, or devices. This
will not involve a rebalance of the ring.
- Changing the port for a device, or group of devices,
carries a brief period of downtime to the swift
storage services for those devices. The devices will
be unavailable during period between when the
storage service restarts after the port update, and
the ring updates to match the new port.
