The VSWITCH depends on the controller virtual machines. It and some related CP
control blocks may be swapped out.
In a hyperswap, you can't do I/O to bring them back in.
Bill is correct regarding the requirements for the GDPS proxy servers.

Are you sure you are interpreting the requirement correctly?
'Everythinggets quiesced during hyperswap' ... how does this relate to z/VM
andVSWITCH?Scott RohlingOn Tue, Mar 7, 2017 at 12:23 PM, Bill Head
