Hello,
I just read this now.   We do the same thing and yes, we have to check if replication is running and cancel it with a sleep. We then send an email to TSM admins to request that it be restarted at their discretion (based on time of day, etc..). The reason for not just re-starting is that we found often node deletions (decommissioning) would happen in batches, so it created a race condition with the replication processes starting and getting cancelled.

Hope that helps.

Hi guys,

Removing an obsolete SP node is an automated process in our company. We 
recently started to use node replication and I now found that our automation 
scripts fail every now and then. Apparently you cannot remove a node when 
replication is running. The required remove replnode results in the following 
error:

ANR2720E REMOVE REPLNODE: Node NODENAME is currently being replicated.
ANR1632E REMOVE REPLNODE: Command failed. Replication state information for the 
specified nodes could not be removed.
ANS8001I Return code 12.

This is not very handy, is it. We now have to make our scripts a lot more 
complex, we have to check if a node replication is running and if so, build in 
a sleep routine...
How do you guys handle this? Thanks for any tips!

Kind regards,
