First Claim
Patent Images
1. A method for active link verification for failover operations in a storage network, comprising:
- issuing a command from a first port of a storage device to a local network device in the storage network;
receiving a response to the command at the first port of the storage device from the local network device in the storage network, wherein the storage device fails over to a second port of the storage device if no response is received at the first port of the storage device.

Abstract
Systems and methods for active link verification for failover operations in a storage network are disclosed. An exemplary method includes issuing a command from a first port of a storage device to a local network device in the storage network. The method also includes receiving a response to the command at the first port of the storage device from the local network device in the storage network. The storage device fails over to a second port of the storage device if no response is received at the first port of the storage device.

6. A storage device configurable for operation with a local network device in a storage network, the storage device comprising:
-
at least a first port and a second port; and program code executable at the storage device to cause (i) issuing a command from the first port, and (ii) failing over to the second port if no response is received to the command issued at the first port. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
