We're having trouble storage migrating a VM that has a 36GB thin provisioned VMDK disk and (2) 1TB virtual mode independent-persistent RDMs (fiber LUNs).
Virtual disk format is same as source, we're not trying to change the format of any of the disks during the migration.
The destination datastore has ~700GB of free space but vSphere/Web client both tell us that there is insufficient space for the RDM disks to proceed when clicking 'finish'.
We swear we've done this before and the RDM total capacity was not taken into account and only the VMDK disk size mattered.
Is this incorrect or had something changed in vSphere 5.5?
Perhaps another issue we're not remembering?
