Predefined Port Groups
There are 3 predefined, automatically created port groups that are available for use, yet
cannot be defined in the policy file (if a group in the policy is configured with the name
of one of these predefined groups, the policy fails) -
ALL - a group that includes all nodes in the fabric
ALL_SWITCHES - a group that includes all switches in the fabric.
ALL_CAS - a group that includes all HCA's in the fabric.
subtract rule One can define a rule that subtracts one
port group from another. The given rule,
for example, will cause all the ports
which are a part of grp1, but not included
in grp2, to be chosen.
In subtraction (unlike union), the order
does matter, since the purpose is to sub
-
tract the second group from the first one.
There is no option to define more than
two groups for union/subtraction. How
-
ever, one can unite/subtract groups which
are a union or a subtraction themselves,
as shown in the port groups policy file
example.
subtract-rule: grp1,
grp2
