Abstract:
1. An information system for Input/Output (I/O) migration comprising: a managed computer executing an Operating System (OS); an I/O switch having plurality of I/O devices coupled with the managed computer via a network; and a migration management module, wherein the migration management module: detects a first I/O function associated with a first I/O device to which the OS is connected, selects a second I/O function associated with a second I/O device which is the same type of the first I/O device, and instructs to hot-add the second I/O function to the OS, wherein the OS: sets a teaming for a first virtual Media Access Control (MAC) address of a first virtual Network Interface Card (NIC) corresponding to the first I/O function and a second virtual MAC address of a second virtual NIC corresponding to the second I/O function after the hot-add of the second I/O function is completed, and disconnects the first virtual MAC address of the first virtual NIC corresponding to the first I/O function after the set of teaming for the first virtual MAC address and the second virtual MAC address is completed, in order to communicate via the second I/O device associated with the second I/O function instead of the first I/O device associated with the first I/O function.
