NetApp - Get a list of all volumes not being used

Wed, 30 May 2012 17:40:12 +0000

Well, I had another task for today … I have an amount of FlexVolumes (sixty currently per controller), and I didn’t know if we had any, that didn’t have any LUNs on them. Now I thought there was a command for that since my co-worker mentioned something like that. However, once again … there isn’t.
