AMASS Overview
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) feature.
After a volume has been assigned to a numerical volume group, all writes to the volume group directory and its subdirectories go to the specified volumes. No other data is placed on these volumes. Therefore, when all the volumes are filled up, subsequent writes fail because the volume group is full. However, when a volume group is full, you can do one of the following:
•Add volumes to the volume group.
