240 Implementing an Open IBM SAN
Building hard zones using port groups
Now we know that a hard zone must consist of port groups. In our example, we
have created two hard zones, as illustrated in Figure 3-55.
Figure 3-55 INRANGE hard zoning: basic example with 2 zones
This picture was taken by using the IN-VSN tool.
Hard Zone A consists of only one port group. Hard Zone B consists of the
remaining 15 port groups. Remember the “all-or-nothing” rule: When
implementing hard zoning, all ports must be zoned.
In the example above, the four ports of Zone A are allowed to talk to each other.
All 60 ports of Zone B are allowed to talk to each other. However, any
communication between Zone A and Zone B is blocked.
Remember that hard zoning strictly excludes ports other than those in the same
hard zone from communicating together.
