| 摘要 |
The present invention is a method for providing multi-pathing via Small Computer System Interface Input/Output (SCSI I/O) referral between an initiator and a storage cluster which are communicatively coupled via a network, the storage cluster including at least a first target device and a second target device. The method includes receiving an input/output (I/O) at the first target device from the initiator via the network. The I/O includes a data request. The method further includes transmitting a SCSI I/O referral list to the initiator when data included in the data request is not stored on the first target device, but is stored on the second target device. The referral list includes first and second port identifiers for identifying first and second ports of the second target device respectively. The first and second port identifiers are SCSI relative port identifiers. The first and second ports of the target device are identified as access ports for accessing the data requested in the data request. |
