import server fails ANR0568W

Hi,

I've got the following setup:

TSM server 4.2.1.11 running on AIX 4.3.3. There are two TSM instances running 
on the server (production and test instance)

I take an export of the production TSM server (which goes fine). Afterwards I 
want to import this export on the test instance (to validate the export). The 
output of 'import server devclass=dds vol=exp preview=yes' is as follows:

03/19/02 14:40:21     ANR2017I Administrator ADMIN issued command: IMPORT SERVER

Why does the preview fails? An import with preview=no gives the same error. If 
I run a test backup, the client-server commnunication goes fine. There are no 
entries in the dsmerror.log file. Has anybody experienced the same problems?

The client-server communication is with shared memory. Both instances use 
different TCP ports.

Thanks a lot,
Kurt
