Not true.  You can do a 'q filespace' from the client or admin client.
Here's the meaning of the message (for version 2, anyway):

Explanation:  The node name you entered is not known by the server, or
you are attempting to access a file migrated to a different node.

System Action:  ADSM canceled the current operation.  You are not
allowed to connect to the server until your node name is registered with
the server.  If attempting to access a migrated file, your nodename must
be the same node which migrated the file.

User Response:  Ensure that you entered your ADSM node name correctly.
If yes, see your system administrator.  Verify that the server is using
closed registration and that your node name is registered with the
server.
