Defining switch data
Using HCD, you can define both ESCON switches (ESCON directors, such as 9032–5) and Fibre Channel (FC) switches. You can define an FC switch as a FICON® FC switch (type 2032) or as a generic FC switch (type FCS). The FICON FC switch supports an internal switch control unit and device whereas the generic FC switch does not.
To define switches in your configuration, you need to know the
switch type (for example, 2032 or FCS).
You need to decide on:
- Switch ID, such as 01
- Switch control unit number and switch device number. A switch control unit and device may be used by RMF for measuring FICON director activities. When you specify a control unit number and device number in the HCD Add Switch panel, a control unit and device are defined to be the same type as the switch. Note that the FCS switch does not support a switch control unit and device.
- Description: text that you use to describe the switch
You also use HCD to define the connections of the switch ports to channels or control units. You can use HCD to define a matrix of all possible connections between any two ports as well.
Defining switch data is optional.
