Define Positive and Negative Prerequisite Resources

Any resource in a prerequisite list can be qualified as a positive or negative prerequisite by adding a plus (+) or minus (-) sign before its name. A positive prerequisite resource is considered to be satisfied when the specified resource is UP, and a negative prerequisite resource is considered to be satisfied when the specified resource is DOWN. Note

Note: Prerequisites that have been prefixed with a plus or minus are never evaluated as subrequisites.

A plus or minus prefix can be applied to a MINOF statement, to resources in a MINOF statement, and to individual resources.

Making two resources negative prerequisites of each other creates a mutually exclusive relationship. For example:

VTAMPROD PREREQ(-VTAMTEST)

VTAMTEST PREREQ(-VTAMPROD)
