Hi, Can you confirm how many volumes are there and of what size?

Re: HP StoreVirtual 4000 - Creating Snapshot

if the LUN is FULL provisioned, then you need as much space as the LUN is, EG, if you have a 100GB LUN, you would need 100GB free for the snapshot!

 

if the LUN is THIN provisioned, then the minimum snapshot size is 1GB and then expands as the data in the LUN changes.

 

other than strange use cases, you should set all LUNs to be thin provisioned for this reason.
