ARS_STORAGE_MANAGER parameter

Determines whether the server program is linked to a cache-only storage manager or an archive storage manager. You must specify this parameter on library and object servers.

You can specify one of the following values:

CACHE_ONLY: Link the server program to a cache-only storage manager.
TSM: Link the server program to an archive storage manager. This is the default value in the ARS.CFG file that is provided by IBM®. Before Content Manager OnDemand can work with an archive storage manager to maintain data, you must install and configure the archive storage manager software.
ADSM: Deprecated. This option has been replaced by TSM. ADSM is still supported for existing customers.
