i am trying to configure new slp from source to target and my storage server is data domain on both the side.
ddboost association also done on both the data domain but in primary side on SLP import slp not able to find.
Are you using AIR or duplication?
If AIR, are the STUs (DataDomain) And Diskpools, STUs the exact same on both target and source? It's been awhile since I last used a DataDomain, but everything has to be exactly the same for AIR. Haven't used duplication since 2014.
If you are doing replication between data domain belonging to the same master server, you don't do import.
It is a simple Managed File Replication (MFR). The OST DDBOOST plugin will tell data domain 1 to replicate to data domain 2 and the master server will know the backup image now exist in a secondary copy.
