Hi all, I've read that it is recommended to move LS mirror source volumes to an aggregate on a node to be upgraded last. Would it be sufficient instead to quiesce LS mirrors, NDU and then resume relationships afterwards? Are there dangers involved in doing it this way?
I am not worried about any temporary performance degridation by quiescing the mirrors, although existing connections must not be inturrupted as they are NFSv3 datastores for ESXi. In fact the only reason I have LS mirrors at all on >2 node clusters is to ahear to best practices.
I'll be NDU'ing a 4-node cluster from OnTap 8.2.2 -> 8.3.2P9 -> 9.1P1.
