Hi,
Are you using jumbo frames by chance? if you are, can you ensure its enabled throughout (vSwitch, iscsi VMkernels, physical switch, SAN, etc). If you are not using Jumbo frames, please ensure everything is set to 1500 MTU.
This error can also happen if what you are trying to present to ESXi isn't wiped already.Try creating a brand new LUN and presenting that to ESXi.
