Claim Text:
1. A computer-implemented method comprising: transmitting, by a disk of a disk array executing a storage network controller of a main storage network, a list of one or more backup storage networks to a translator module; receiving, by the disk array executing the storage network controller of the main storage network, a failover command from the translator module, the failover command instructing the disk array executing the storage network controller of the main storage network to disable writes of data from a failed server to a storage space of the disk array of the main storage network; responsive to the disk array executing the storage network controller of the main storage network receiving from the translator module the failover command identifying a storage space of a disk array of a backup storage network of the list of one or more backup storage networks; disabling, by the disk array executing the storage network controller of the main storage network, writes to a corresponding storage space of the disk array of the main storage network; and enabling, by the disk array executing the storage network controller of the main storage network, writes to the storage space of the disk array of the backup storage network.
