Switch-attached disks (disks that are attached to the storage system through a switch) use the following name format: Switch_name:switch_port.diskID.
Switch_name refers to the name given to the switch when it was configured.
Switch_port is the number of the switch port that the disk is attached to.
A disk with ID 24, connected via FC-AL to the storage system through port 5 of switch SW143, would have the following name: SW143:5.24
