ABSTRACT:
A system and method for clustered failover over transport media that does not support moving of transport addressed between network interface controllers is provided. This reviving file server of a cluster, upon detection of the failure of its partner, assumes ownership of the disks owned by the failed file server. The surviving file server activates a secondary discriminator or port for access by clients who normally utilized the failed file server. Clients generate the name of the surviving or failover file server by appending at set item to the name of the failed file server.
