Primary, Secondary, UDFS disk pools

 

An independent disk pool that contains user-defined file systems, directories and libraries, or associated directory and library information.

 

User-defined file system (UDFS)

An independent disk pool that contains only user-defined file systems. It cannot be a member of a disk pool group unless it is converted to a primary or secondary disk pool.

 

Primary

An independent disk pool that defines a collection of directories and libraries and may have other secondary disk pools associated with it. A primary disk pool also defines a database for itself and other disk pools that may be added in its disk pool group. Primary disk pools can only be implemented on OS/400^® V5R2 or i5/OS^® V5R3 and later.

 

Secondary

An independent disk pool that defines a collection of directories and libraries and must be associated with a primary disk pool. A possible use for a secondary disk pool might be to store journal receivers for the objects being journaled in the primary disk pool. Secondary disk pools can only be implemented on OS/400 V5R2 or i5/OS V5R3 and later.
