ALTERING ACCESS TO A FIBRE CHANNEL FABRIC

摘要

A mechanism is provided for altering access to a network. A virtual I/O server controller in a virtual I/O server operating system receives an indication that an identified communications adapter requires attention. The virtual I/O server controller issues a set of calls to a set of N_port identification virtualization (NPIV) server adapters coupled to the identified communications adapter. Each of the set of calls indicates to each of the set of NPIV server adapters a request to move a set of clients from their assigned port on the identified communications adapter to an available port on a failover communications adapter. The set of NPIV server adapters moves the set of clients from the identified communications adapter to the failover communications adapter.
