Storage set

A storage set is a named collection of storage nodes that support application groups with similar storage management characteristics. For example, a storage set can maintain data for several application groups that need to keep documents for the same length of time and store the data on the same type of media.

You typically define one or two storage sets for a Content Manager OnDemand system, based on the storage requirements of the reports that you plan to archive in Content Manager OnDemand. For example, you might define one storage set to maintain data for ninety days and another storage set to maintain data for seven years.

A storage set can contain one or more primary storage nodes. A primary storage node is where Content Manager OnDemand manages reports and resources stored in an application group. A storage node identifies the Content Manager OnDemand object server on which the application group data is stored. If you use TSM to manage application group data in archive storage, then each storage node that writes data to TSM-managed storage must be registered as a client node in a TSM domain. The properties of the domain determine the devices used to hold the data and how long that TSM maintains the data. Note about migration storage nodes: The administrative client can be used to view storage nodes that were created during migration from OD/390 V2, OD/390 IAFC, and OD/400 Spool File Archive.

Note: Content Manager OnDemand no longer supports adding secondary storage nodes when you create a storage set. When updating a storage set, secondary storage nodes can only be created if the storage set already contains one or more secondary storage nodes. If you need to maintain a backup copy of data in archive storage, then IBM recommends that you configure the archive storage manager to do so.

Note about IBM® i servers: Add, Update, and Delete operations for storage sets have been disabled on IBM i servers. A storage set is created, updated and deleted as the result of actions performed on the migration policy in IBM Navigator for i. The storage set name is the same as the migration policy name.
