Re: Many warnings
Can you check if the client entry created for that storage node is created with the exact same name (short name or FQDN)as the storage node itself?
In some cases the client is created like "sn_client", and the storage node is created as "sn_client.domain.com"
Is the storage node enabled? Go to Media, and click on storage nodes, on the right side of NMC you will see the status of the storage node, also ensure that nsrsnmd and nsrmmd's processes are started on that SN
