There is no limit to increase / decrease volume / lun size </P><P>2. I did a research a while ago in regards of that issue for windows hosts, what i found is: there is no limit as long as you do not assign a drive letter. We currently use mount points on W2008 boxes and the average amount of luns 50+.</P></BODY></HTML> Thu, 07 Mar 2013 22:00:54 GMT https://community.netapp.com/t5/VMware-Solutions-Discussions/LUN-and-Volume-size/m-p/70867#M6736 vims 2013-03-07T22:00:54Z Re: LUN and Volume size https://community.netapp.com/t5/VMware-Solutions-Discussions/LUN-and-Volume-size/m-p/70872#M6737 <HTML><HEAD></HEAD><BODY><P>bear in mind though a NetApp LUN cannot be increased to more than 10x of its initial size.</P></BODY></HTML> Fri, 08 Mar 2013 09:53:02 GMT https://community.netapp.com/t5/VMware-Solutions-Discussions/LUN-and-Volume-size/m-p/70872#M6737 radek_kubka 2013-03-08T09:53:02Z Re: LUN and Volume size https://community.netapp.com/t5/VMware-Solutions-Discussions/LUN-and-Volume-size/m-p/70877#M6738 <HTML><HEAD></HEAD><BODY><P>There is (or at least, was) limit to how far you can increase LUN size.
