Hi,  I got a vnxe3100 with the lastest VNXe Operating Environment MR3 SP1.1 - 2.3.1.20364.  I woud like to delete a storage pool but i cannot :  the “recycle disks” is grayed.  There is some used storage (80%) in the pool.  But there is no lun,no share storage , no checkpoint, no nfs, no cifs on the vnxe3100.  I used to do some test - create nfs server, shared storage withe the pool above- but i delete all.  I have got a  error message when i created a share storage on the storage pool above  - full storage ...-.  Since this message, this issue  above apparead.  How can i see what storage is used and how to delete the used storage if i wanna to recycle disk from my storage pool.  thx.
