Predefined qualifiers for prerequisite properties
IBM Prerequisite Scanner provides a set of basic qualifiers for some prerequisite
properties in a predefined category. Qualifiers represent attributes of the
prerequisite property that Prerequisite Scanner uses to qualify the prerequisite
property or type of check to perform on that prerequisite property.
For example, you can have a prerequisite property for a file system. You can
qualify which check to perform for that prerequisite property based on its file
system name and access permissions attributes. You can also qualify which type of
units to use when checking the available disk space based on the file system path
and unit attributes.
Qualifiers support customization to meet the needs of your environment and
prevent the Scanner having to make implicit assumptions about the attributes of
multidimensional prerequisites such as the default path and access permissions.
You can change the values for the predefined qualifiers, but you cannot add new
qualifiers to the existing set of predefined qualifiers for a predefined prerequisite
property.
Qualifiers must adhere to the following format:
[qualifier_name:qualifier_value, qualifier_name:qualifier_value]
