120 IBM Content Manager OnDemand Guide
If you plan to add a virtual optical level later to take advantage of improved save and restore 
times or to use the WORM option, you can initially specify 90 days, for example, for the disk 
pool level, with no other defined storage levels. When a virtual optical level is added later, the 
archives are moved from the disk pool level to the virtual optical level. With this technique, you 
must never add an expiration level after the disk pool level because if that level is 
encountered, the archives are expired.
In the status report that is created by ASM, you might see messages that indicate that the 
number of days in the ASP01 disk pool level was exceeded because no level is available after 
90 days in this example. Y ou can ignore these messages.
If you choose the default in the application group to migrate data from cache when data is 
loaded, a copy of the data is archived to the integrated file system (IFS) CACHE directory and 
to the ASMREQUEST directory. When you run Disk Storage Manager, the data is deleted 
from cache after the Cache Data for Days duration ends. When you run ASM for the first time 
after you load data, the data is moved to the first level of the migration policy, ASP01 in our 
example. If aggregation is used, the data is not migrated until the appropriate object size is 
aggregated, or until the number of days to aggregate was passed. The data remains in 
ASP01 until the number of days in the Life of Data and Indexes is reached or an expiration 
level in the migration policy is encountered, whichever comes first.
Most administrative functions for Content Manager OnDemand for i can be carried out with 
the Content Manager OnDemand Administrator Client. The objects that are necessary for 
Content Manager OnDemand archive storage management on IBM i are created by using the 
Content Manager OnDemand component of the web-based IBM Navigator for i (Figure 5-17).
To create a migration policy for use by the archive storage management process, storage 
devices must be defined for the types of archive media that are required by the Content 
Manager OnDemand system. For our scenario, we created a disk pool storage group and an 
optical storage group.

Disk pool storage group
A disk pool storage group is used to identify an IBM i auxiliary storage pool that ASM uses as 
disk storage media when it migrates archived data. Use IBM Navigator for i to add a disk pool 
storage group (Figure 5-18 on page 121).
