Definitions

[ extentname ]

Specifies a one- to eight-character name associated with this extent description. The extentname field is optional and is only used by the IBM System Management API Server; for more information, see the appendix "Systems Management API Support" in the Administration Guide. Each extentname statement name must be unique and cannot be used by any other statement in any configuration file.

beginning

Specifies the first cylinder or block number in this extent.

ending

Specifies the last cylinder or block number in this extent.

subpool ...

Specifies the names of up to eight subpools, separated by blanks that can allocate space in this extent.

* comment

Identifies the fixed CP extent and provides documentation. The asterisk identifies this extent as a fixed CP extent, and the comment provides documentation about its use. These comments appear in volume maps produced by the MAP command. No subpool names can be assigned to a fixed CP extent; therefore, no space can be allocated from a fixed CP extent.

You do not need to identify disk space used by guest SCPs.
