extmem.e08a4c DCSS <DCSS name> overlaps with used storage and cannot be loaded
Explanation
You cannot load the DCSS because it overlaps with an already loaded DCSS
or with the memory of the z/VM guest virtual machine (guest storage).
User response
Ensure that no DCSS is loaded that has overlapping memory resources
with the DCSS you want to load. If the DCSS overlaps with guest storage,
use the DEF STORE CONFIG z/VM CP command to create a sufficient storage gap
for the DCSS. For details, see the section about the DCSS device driver in
"Device Drivers, Features, and Commands".
