Abstract:
In one implementation, a system includes multiple SCSI nodes configured to perform a SCSI target function. Each of the multiple SCSI nodes includes a host bus adaptor configured to connect the SCSI node with a Fiber Channel fabric. The host bus adaptor being assigned a world wide name and a network address. The system further includes a host configured to perform a SCSI initiator function. The world wide name assigned to a source host bus adaptor associated with one SCSI node is relocated to a target host bus adaptor associated with another SCSI node. After that, the network address associated with the source host bus adaptor is relocated to the target host bus adaptor. In one implementation, the system determines whether or not a network address assigned to a source host bus adaptor associated with one of the multiple SCSI nodes is shared with at least one other service. If so, the system determined whether the shared network address can be relocated to a target host bus adaptor associated with another one of the multiple of SCSI nodes. If the latter determination is in affirmative, the world wide name and network address are relocated.
