A WWN consists of an 8-byte hexadecimal number with each byte separated by a colon. For example, 10:00:00:60:69:00:00:8a is a valid WWN. Using WWN port name zoning allows you to move cables between switch ports within the fabric without having to update the zones. Table 3-1 provides a list of WWN identifiers that you can find in the Dell/EMC cluster environment. Table 3-1.

Single Initiator Zoning Each host HBA port in a SAN must be configured in a separate zone on the switch with the appropriate storage ports. This zoning configuration, known as single initiator zoning, prevents different hosts from communicating with each other, thereby ensuring that Fibre Channel communications between the HBAs and their target storage systems do not affect each other. When you create your single-initiator zones, follow these guidelines: 40 Preparing Your Systems for Clustering
