I have a VM that is on a 5TB datastore and had a 8TB RDM attached to it. I need to Storage vMotion the attached VMDK , config and RDMP pointer files to another datastore. The datastore I need to move to is 7TB and keep getting the error insufficient space for the RDM lun. Which is odd since this is just a pointer file from my understanding. I have tried storage vmotion each disk one by one and when I hit the RDM it always ends in the same result.
