Re: [ADSM-L] Question about TSM 7.1 Node Replication

Hi,

That is right, run a REMOVE REPLNODE node_name on the target server, re-direct 
the nodes to the target server (setting tcpserveraddress and tcpport) AND do 
remember to check that node and the target server agree on the node password.

If/when the source server becomes available again, set up replication from the 
target server to the source server 

On source server: 
REMOVE REPLNODE node_name for all previously replicated nodes

On target server:
SET REPLSERVER source_server
UPDATE NODE node_name REPLSTATE=enabled REPLMODE=syncsend

When the target and the source are in sync, remove replication again and 
re-enable it from the source server with REPLMODE=syncsend - and redirect the 
client nodes back to the source server.

Hi Mike,

was looking for the same thing some days ago.
Found this in the V7.1 Info Center:

Converting client nodes for store operations on a target replication server:
If a source replication server is unavailable, you can convert client nodes to 
be non-replicating nodes. Non-replicating client nodes can back up, archive, or 
migrate data to a target replication server.

Best regards,
