AMASS Overview
1-12 Online Archiving with AMASS 6-00026-01 Rev A
The following figure illustrates these volume groups:
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.
Cleaning cartridges are assigned to the cleaning
group (CL). When a drive needs cleaning, AMASS
selects the appropriate cleaning volume from this
group.
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.
Volumes can be assigned to a numeric volume
group. The group can be a number from 1 through
2047.

Media verification group. A volume assigned to the
