Managing the AMASS File System
The following figure illustrates these volume groups.
Numeric Volume Group
Space Pool
Volumes can be assigned to a numeric volume group. The group can be a number from 1 through 2047.
Volumes can be assigned to the space pool (SP). These are formatted volumes with specific attributes. When a numeric volume group runs out of space, and it has been enabled to use the space pool, AMASS automatically takes a volume with the same attributes from the space pool and assigns it to the numeric group that ran out of space. Thus, AMASS can continue to write data to the numeric volume group.
Cleaning Group
Media Verification
Cleaning cartridges are assigned to the cleaning group (CL). When a drive needs cleaning, AMASS selects the appropriate cleaning volume from this group.
Media verification group. A volume assigned to the media verification (MV) volume group consists of media verified as “good” for the AMASS Infinite File 
Life (IFL) optional feature.
Both numeric volume groups and the cleaning group must contain a homogeneous type of media.
At a site using both WORM and erasable optical platters, for example, volume group 47 can contain WORM platters or it can contain erasable platters, but it cannot contain both media types.
