I have RME4.1.1. I can't open Adhoc>Add Instance... The Windwos too small (s. Attachment).
That's what I thought. This is a bug I found when doing ZFS testing. Unfortunately, since LMS 3.0.1 isn't officially supported on ZFS, I cannot provide you a patch. I do, however, have a patch for LMS 3.1.
There is a workaround, though. Copy /opt/CSCOpx/MDC/tomcat/webapps/rme/WEB-INF/lib/pkgs to some other file system. Then delete /opt/CSCOpx/MDC/tomcat/webapps/rme/WEB-INF/lib/pkgs. Then, copy the directory back from the other file system. Restart dmgtd, and you should be able to use Netconfig.
For the record, the bug is CSCsr13209.
