Expanding or growing a VMFS datastore
It is likely that you would run out of free space on a VMFS volume over time as you end up deploying more and more VMs on it, especially in a growing environment. Fortunately, accommodating additional free space on a VMFS volume is possible. However, this requires that the LUN either has free space left on it or it has been expanded/resized in the storage array.
The procedure to resize/expand the LUN in the storage array differs from vendor to vendor, and as this is beyond the scope of this book, we assume that the LUN either has free space on it or has already been expanded.
