• Status changed from New to Rejected

That works as designed - multiple dependencies don't know about each other, and if one of them fails it renders the child unreachable. Your request sounds a lot like multi-parent dependencies combined with a logical "AND". This is discussed in #6871 - please continue over there and suggest your solution/ideas.

Coming from #10058, you did not add a small detail - where the host esx1 is supposed to be UP instead of unreachable. Talked with Tom about that in detail.

We will continue about that in #10058, sorry for not asking before. I was under the impression that you're talking about multi-parent dependencies and logical AND.

@lbetz: you should have mentioned that esx1 used to be up. Saupreiß ;)
