Abstract
An upgrade process is provided to upgrade first and second switches in a converged network handling storage area network traffic and data network traffic, in which the first and second switches are coupled to a host, e.g., a Fibre Channel over Ethernet (FCoE) via distributed network links, e.g., Virtual PortChannel links or Distributed Resilient Interconnect (DRNI) links. The first switch is isolated from the host so that all distributed network links traffic associated with the host is transferred to the second switch. The firmware of the first switch is upgraded while all distributed network links traffic associated with the host is handled by the second switch. The firmware of the second switch is upgraded is a similar manner while all distributed network links traffic associated with the host is handled by the first switch.
