Yes it is normal. Once you scan your ESXI server and it will check not install patch and update .
Sorry, but the update01 shoud not be already in the iso?
Yes, this is just a quirk with VUM, and not isolated to any vendors' builds. There's no harm in selecting the U1 bundle that already exists and letting it install. It essentially skips it and doesn't mess with settings. Once you allow it to do that, it'll remove that update from the manifest in a baseline.
Thank a lot daphnissov, I will try.
