Patent ID: 7415535

Claim:
A method comprising: configuring in a configuration for a first storage router a plurality Internet Protocol (IP) addresses for each of a plurality of SCSI routing applications on the first storage router, wherein each SCSI routing application is provided a different IP address; replicating the configuration to a second storage router; creating a plurality of virtual MAC (Media Access and Control) addresses, each virtual MAC address associated with one of the different IP addresses; setting an OUI (Organization Unique Identifier) portion of each virtual MAC address to an OUI value; setting a non-OUI portion of each virtual MAC address to a subset of the different Internet Protocol (IP) address associated with the virtual MAC address; detecting a migration event on the first storage router; initializing on the second storage router the plurality of SCSI routing applications according to the replicated configuration, wherein each of the plurality of SCSI routing applications is assigned the different IP address according to the replicated configuration; and recreating on the second storage router the plurality of virtual MAC addresses, each virtual MAC address associated with one of the different IP addresses and each created on the second storage router by setting an OUI (Organization Unique Identifier) portion of each virtual MAC address to an OUI value and setting a non-OUI portion of each virtual MAC address to a subset of the different Internet Protocol (IP) address associated with the virtual MAC address.
