Hi there, to let you know, I just get the following response from the engineer team;
The following steps may be creating an error.
1. vmap rtest <library_path> : This step is creating the mapping with the name of rtest
2. vmap -del rtest : This step deletes the mapping done with the name of rtest. It means, Questa no more identify any library with the name of rtest
3. vdel -all -lib rtest: Here user is trying to delete the rtest library which no more exist. As logical link is deleted. User has to pass the full path of library now to delete it instead of rtest.
Alternative is to switch the sequence of step 2 and 3. Perform vdel first and then vmap -del
Let me know if you still face any problem.
