That doesn't make sense. When you have the DNA, if the source person is dead and in the pure land he is resurrected, and you only need the DNA. The only reason the reincarnation could fail is that the soul of the DNA's possessor is not in the pure land: there is no room for "it isn't the right DNA", because if the DNA was wrong the technique would simply resurrect the wrong person. It was shown in the anime (Kabuto resurrected Chiyo thinking her blood was Sasori's) and if I'm not mistaken was also explained when Kabuto resurrected Torune (you smear the DNA on the IWR scroll and cast the technique, than the target is resurrected, it was never said that you also have to "specify" who you want to resurrect).

So if Kabuto used Jiraiya's DNA (hair, skin, whatever you want) but failed to resurrect anyone, he would have known that Jiraiya was not in the pure land and didn't bothered searching for his body
