Optical storage groups

Optical storage groups are used by IBM® Content Manager OnDemand to group sets of optical volumes together to store related data. A storage group lets you group together reports that have similar storage requirements such as days on disk or expiration days. By referring to a specific storage group in your migration policy, you can control which reports are stored on a particular set of optical volumes. If optical volumes are defined as rewritable, the space can be reused on the volume by defining a free space threshold percent and volume full reset. If the volume full reset is not defined, once the volume is marked full it remains full unless manually changed. The optical storage group can also be defined as the primary or backup storage group.
