The NVMe stand-alone dump can be used only on IBM z15 or newer
machine generations because it requires larger amount of HSA memory offered
by firmware only on IBM z15 machines. Whereas the SCSI stand-alone dump is able
to work with HSA memory of 32M, the NVMe stand-alone dump requires 512M HSA
memory.
