Configuring a PDCM Allow/Prohibit Matrix
The Prohibit Dynamic Connectivity Mask (PDCM) is a FICON port attribute that can be used to
prohibit communication between specific ports. Prohibits are not recommended on E_Ports (inter
switch links).
The PDCM can be manipulated by host-based management programs using FICON CUP, or from a
Management program to create policies and determine paths for data and command flows. Up to 8
PDCM matrices can be modified at the same time. PDCM settings apply per switch rather than per
fabric, and only work when an active zone configuration is present in the fabric.
Multiple configurations may be defined, edited, copied, or removed. Only one configuration may be
active per switch.
1. Select Configure > Allow/Prohibit Matrix.
The Configure Allow/Prohibit Matrix dialog box is displayed.
