Hi,
Please check the below note.
Please check if you are impacted with the below note. Apply the fix if necessary.
1823721 - RBDLSMAP problems during client copy: SUMMARY
as per note above:
As a workaround, in case the client copy was started in foreground, this problem can be overridden by starting the client copy in background mode. Starting on foreground the process stops when RBDLSMAP sends a warning concerning already existing logical system name. This warning must be confirmed for RBDLSMAP to run further, which does not occur in background mode.
So you can just perform all the normal post copy steps.
we20,we21,bd64, scc4 settings and bd87,SM59,SCOT,SUW3 and etc.
Note 1683841 - client copy kept failing at RBDLSMAP
1840881 - RBDLSMAP and CALL_FUNCTION_PARM_UNKNOWN during client copy
Logically its better to run the client copy again to fix all the issues and not miss any step.
Thanks
Rishi Abrol
