Mirroring fails sometimes due to various number of reasons and since mirror fails, current code does not generate idms & itms files. Even if user tries to mirror the operators  twice or thrice the operators does not get mirrored and no resources are created to utilize the operators that have already been mirrored. This bug is to create idms and itms even if mirroring fails
