Even changing the dpReaperInterval=1minute and deleting all Datasets need to wait very long time until DFPM does delete existing snap-mirrors/vault. Only after min. 1 - 2 hours and even with set dpReaperInterval=1minute relations-ships are deleted. Why not after 1 min? Anybody Idea.
The reason is, there is one more option which actually deletes the relationship and has a default value set to 60mins. This was done so that we conservative in deleting a relationship, as sometime it could have be done mistakenly and customer want to prevent it.
The dpReaperInterval is basically to find relationship which are orphans or redundant and not actually to delete.
