User response
Ensure that the storage pool is enabled for client-side data deduplication: run "q stg <pool name> f=d" and verify that the value of "Deduplicate Data?" is "yes". Ensure that client-side data deduplication is enabled on the server. To enable client-side data deduplication, use the DEDUPLICATION parameter on the REGISTER NODE or UPDATE NODE server command. Set the value of the parameter to CLIENTORSERVER. The value of the DEDUPLICATION option on the client must be set to YES. You can set the DEDUPLICATION option in the client options file, in the preference editor of the Tivoli Storage Manager client GUI, or in the client option set on the Tivoli Storage Manager server. Use the DEFINE CLIENTOPT command to set the DEDUPLICATION option in a client option set. To prevent the client from overriding the value in the client option set, specify FORCE=YES. Ensure that the deduplication parameter for the node is "ClientOrServer": The value of the DEDUPLICATION option on the client must be set to YES.
