Sorry, using polish by default.. see please below:

Got mksysb done using NIM; used nim -o define.. - and,
what is somehow expected, cannot use same command again,
to have fresh mksysb (resource already exists).
Question is how to do fresh mksysb using NIM, any advices?
So far I though may use some script to remove old resporce,
and create new one with mksysb every day, but looks little
bit artificial.. any other suggestions pelase?
Thanks you in advance and regards
