114 VERITAS Storage Foundation ISP Administrator’s Guide
Capabilities
A capability, as expressed in the ISP language, is a description of what a volume is capable of
doing. Each template is associated with one or more capabilities so that ISP can choose those
templates that are suitable for use in allocating storage to volumes. A capability is interpreted by
ISP as a tag.
The format of a typical capability definition is shown here:
capability cap_name {
extends capname1,capname2, ...
description text
descriptionid id
display_name name
display_name_id catalogid, index
var varname1:type {
defaultvalue value
description description
descriptionid catalogid, index
}
var varname2:type {
defaultvalue value
description text
descriptionid catalogid, index
}
...
};
This definition has the following important components:
cap_name Indicates the nature of the capability, for example, Reliable,
Performant, Snapshot and EMCSnapshot.
extends Indicates that the capability is derived from other named capabilities. See
“Inheritance of Capabilities” on page 115 for more information.
