Method and system for managing a storage network to reduce power consumption

A routing storage network device for managing a storage network system comprising a plurality of zones, each of the plurality of zones comprising at least one storage network device, the routing storage network device comprising:

• a computer-readable medium;
• and
• a processor in operable communication with the computer-readable medium, the processor:
• detects a link-down event associated with one of the storage network devices, wherein the link-down event is at least one of a device failure, a cable failure, and a planned device power interruption,
• determines whether alternative storage network devices in an identified one of the plurality of zones where the link-down event occurred are in a link-down state, wherein at least a zone table and a routing table is used for the determining;
• and
• in response to all of the storage network devices being in the link-down state, places the identified one of the plurality of zones where the link-down event occurred in a down state.

A computer program product for managing a storage network system comprising a plurality of zones, each of the plurality of zones comprising at least one storage network device, the computer program product embodied on a non-transitory computer-readable storage medium having computer-readable program code portions stored thereon, the computer-readable program code portions comprising:

• computer program code for detecting a link-down event associated with one of the storage network devices, wherein the link-down event is at least one of a device failure, a cable failure, and a planned device power interruption;
• computer program code for determining whether alternative storage network devices in an identified one of the plurality of zones where the link-down event occurred are in a link-down state, wherein at least a zone table and a routing table is used for the determining;
• and
• computer program code for, in response to all of the storage network devices being in the link-down state, placing the identified one of the plurality of zones where the link-down event occurred in a down state.
