Connectivity - Hosts When there is an active I/O operation occurring between a host and ColdspellX Fibre Channel port on the appliance, and there is a considerable amount of logout and login activity initiated by the hosts, the port may report a BUSY status back to the host even when the port is not oversubscribed from a limits standpoint. Contact your service provider. Connectivity - Hosts Xcopy operations can impact host I/O None performance.
