Storage pools can be defined with RECLAMATIONTYPE=THRESHOLD or RECLAMATIONTYPE=SNAPLOCK. A device class can only be used with either RECLAMATIONTYPE=THRESHOLD or RECLAMATIONTYPE=SNAPLOCK storage pools. An attempt was made to define a storage pool with one type of reclamation type with a device class that is already associated with another storage pool of the other reclamation type.
The command fails.
Reissue the command and specify another device class that is referenced by storage pools with the same reclamation type as your new storage pool. You may need to define another device class.
