As we all are aware of that only one VM with unique name can be register only once on an esxi.
Here I have an esxi where I have vm sv1000 which is in powred off status. Now I have mirrored a LUN from my other Vcenter and adeed it ont my corrent ESXi where sv1000 vm exists, The LUN which I have migrated there is a vm files exist of sv1000 which was running on my old vcenter. Now by mistake I have register sv1000vm into my existing esxi and that got added without any issue.
Now Im having old VM called sv1000 which was there on ESXi and the other VM which I registered from new provision LUN. Im not sure how that happen...
