Add a single partition to an existing aggregate on a C800
I have two spares drives in the machine, each are root-data-data, and I have one other single data partition on another drive. I have a single data aggregate which has two plexes, one containing 10 partitions & the other is 9 partitions. Is there some way of adding the single spare data partition to the the plex that only has 9 data partitions? Thanks in advance.
