What does it mean?
Hi friend,
Let us know, what is your ESXi version and build number?
BR
ESXi Version 5.5.0
Build 3248547
Hi friend,
It seems, you have duplicate LUN presented to your server with this ID: naa.600507604e3e0d7f569fd76600000007
Try to un-present all LUNs from your ESXi servers and re-present them again.
If problem was not resolved, ask your storage vendor to check the issue.
