Independent disk pools are disk pools 33 through 255. Independent disk pools can be user-defined file system (UDFS) independent disk pools or library-capable independent disk pools.
UDFS independent disk pools are independent disk pools that only have a user-defined file system. UDFS independent disk pools cannot store journals and receivers. In contrast to UDFS disk pools, library-capable independent disk pools have libraries and are capable of storing journals and receivers. If you plan to journal objects on an independent disk pool, you must use a library-capable independent disk pool.
You cannot journal objects on a UDFS independent disk pool.
Independent disk pools can also be switchable or dedicated. Dedicated independent disk pools are used on only one system. Switchable independent disk pools can be switched between systems. If they are library-capable, you can journal objects on either switchable or dedicated independent disk pools.
You can group switchable independent disk pools into disk pool groups. Disk pool groups consist of one primary disk pool and one or more secondary disk pools. If you are going to journal an object in a disk pool group, the object and the journal must be in the same disk pool. The journal receiver can be in a different disk pool, but must be in the same disk pool group as the journal and journaled object.
Use the following rules when journaling objects on independent disk pools:
