Unable to see Lun in ESX

[RAMACHANDRA_CL]

I have created a cloned volume named clone1 which has two LUNs lun1 and lun2 in two seperate qtrees presented to ESX host through FC. After mapping from filer, I can able to access first lun in ESX without any issue, but second lun lun2 is asking for format.

How to overcome this issue without creating another cloned volume? Need help from experts..

maybe it has something to do with the VMFS signature. as it is a clone, it has the same VMFS signature as the original volume. so ESX does not automatically mount it due to security reasons. under mounting options you should select "Assign a New Signature".
