There is no user- or host-accessible FTP server in the HMC.  Years ago there 
was one, but no longer.   The HMC today (2.14) can act as an FTP *gateway* for 
the "Load from Removable Media or FTP Server" task on the SE out to some 
external FTP server in your network, but it cannot serve as a 
network-accessible FTP server.

I pointed out in a previous post that there IS a way for the host to access 
data on the removable media, and the VM FTP server does so, but it requires the 
co-operation of someone authorized on the HMC to go in and give the LPAR access 
(only one LPAR at a time).  If you perform a "Load from Removable Media or FTP 
Server" and point to removable media, *I believe* the media remains associated 
with the loading LPAR until the LPAR is reset, another LPAR loads from the 
media, or an HMC user specifically disassociates the media from the partition.

But don't confuse arbitrary access to the removable media with the Load task.  
The Load function stores data from the media at specified storage locations and 
then does a SYSTEM RESTART to load the restart PSW and start running.  
Arbitrary access is more like "read file xxxx".

I believe that z/OS has some capability in this space as well, but I don't know 
the details.
