I am currently experiencing what looks to be full VV's on the 3PAR StoreServ side. The "Used User Size (% Full)" is displaying as 95-100% for multiple VV's but this does not seem to be causing an issue with my vmWare environment. I am not sure what to do in order to resolve this issue. I will say that this environment is Thin/Thin provisioned I am not sure if this will factor in to our current situation. We have begun a discussion regarding possible changes to this but no action taken yet. Any guidance or assistance is greatly appreciated.

If you have VMFS6, thin on thin is good.

If you have VMFS5, your disks are full because Vmware is a lazy bastard that never cleans up. Run unmap on the drives and wait. And a big suggestion is to use Eager Zero Thick in Vmware to help 3PAR reclaim unused spaced by making Vmware write some zeros.

Thank you for the info. I will run through this process on my current datastores and also look into updating all VMFS 5 to VMFS 6.
