If both V-Switches are on the same SCSI bus, you need to eliminate the storage device internal terminator, if present.

    Create targets first and later assign LUNs to the pre-created targets. The V-Switch in Figure 7-1, contains three iSCSI targets: Target 1, Target 2 and Target 3. It has two portals: (IP1, 5003) and (IP2, 5003). Target 1 and Target 2 have only one volume attached to each.

  • Page 121: Identities

    Each initiator can access, read and write into the volume. Identities To allow selective iSCSI initiator access to iSCSI target volumes, the V-Switch uses identities to define pools of initiators. An identity is a user-defined list of iSCSI initiators. An identity can contain from one to multiple initiators, with each initiator having a unique WWUI.
