I have this issue with our VM Error opening the disks for virtual machine eNSVM]. Verify that the correct transport mode is selected. See. I have tried all I could. Not until I had to use this option of intellisnap,
It works but the challenge here is I used the ESXI virtual machine as a snap engine it worked but the issue is once it finished doing backup of that virtual machine it doesn't delete the snap from the VM I have what setting I can implement to achieve this.
