/SM590000Volume is full: Set when the optical volume reaches its capacity.
/SM590000Opposite side volume name: For the other side of the optical platter (only required for 
REWT, WORM, and UDF2).
After the storage groups are established, use IBM Navigator for i to define the migration policy 
that is needed to use the storage groups (Figure 5-21).
Figure 5-21   Content Manager OnDemand for i migration policy definition
The migration policy definition includes the following items:
/SM590000Policy name and description: This field is for the policy name and its description.
/SM590000Enable aggregation: If this item is selected, ASM combines individual archived objects into 
larger objects to provide a more efficient process. Archived objects are appended to the 
same file until the aggregate is closed.
/SM590000Maximum size: The value of this field determines the maximum size of the aggregate file. 
ASM closes the existing aggregate and opens a new aggregate when the maximum value 
is reached.
/SM590000Close aggregate only when maximum size is reached: If this item is selected, the 
aggregate stays open until the maximum size is reached.
/SM590000Close aggregate based on number of days: The value in this field specifies the number of 
days before an aggregate closes. ASM closes the aggregate after the specified number of 
days or when the specified maximum size is reached, whichever occurs first.
Tip: The preferred practice is to put information, such as the length of time and the 
location of the data, in the description rather than in the policy name field. Y ou can 
change, add, and delete levels, but you cannot change the name. If your requirements 
change, you do not want a name that is no longer accurate.
