Task 12: Assign Port Names and Nicknames
During the planning process, consider assigning names to director and switch
ports based upon devices connected to the ports. Though not required, port
naming provides convenience and ease of use. Port naming also documents
devices that connect through individual ports and identifies what is attached to
each port. When it is necessary to change port connectivity, port names make it
easier to identify the ports and attached end devices.
Also consider assigning nicknames to device and fabric World Wide Names
(WWNs). Though not required, nicknaming provides a useful substitute for the
cryptic eight-byte WWN. Once a nickname is assigned, it is referenced
throughout the HAFM application.
Transfer port names and nicknames to the product planning worksheet provided
as part of “Task 13: Complete the Planning Worksheet” on page 191.
Rules for Port Names
Port names can be up to 24 alphanumeric characters long. Spaces, hyphens ( - ),
and underscores ( _ ) are allowed within the name. Each port name must be unique
for a director; however, the same port name can be used on separate directors and
switches. HP recommends that unique port names be used, particularly within a
complex multi-switch fabric. Example port names include:
Lab server
Test system-2
Printer_001
Rules for Nicknames
Nicknames can be up to 32 alphanumeric characters long. Spaces, hyphens ( - ),
and underscores ( _ ) are allowed within the name. Each nickname must be unique
(corresponding to a unique WWN). Example nicknames include:
Fabric-1
Host system
DASD_001
