I'm new to NetApp so I'm asking this question. I have a storage cluster runnin 8.3P1. I need to run space reclaim on the entire cluster to attempt to reclaim space.
I can barely find any information on the process, much less the ACTUALLY commands to run the reclaim. Can is be done only by volume? Can it be ran by an aggregate level? Can you run it on all volumes at once?
No matter the answer, what is the actual command to run the reclaim??
Thanks in advance!

I'm not using Snap drive. The clients are ESXI servers and I would assume NetApp requires VAAI be installed to perform and uNMAP from ESXI?
Other vendors require that, as the storagr won't know what the client is requesting or wanting to happening.
You are correct, with ESXi there is no snapdrive. If you have ESXi 6.5 or newer you can enable space alloction on on the LUN. Follow the link below and it will show you have to enable it. One thing the documentation calls out is taking the LUN offline before enabling space allocation. I've change multiple LUNS in the past whithout taking them offline, do so at your own risk.
Space Reclamation only applies to FC/iSCSI LUNs. If you are using NFS, then it is always done anyway automatically.
