--- Comment From hbath...@in.ibm.com 2017-03-21 13:08 EDT--- (In reply to comment #5) > /proc/vmcore is generated by kdump support in the kernel. This might not be > a bug, but a case of missing support for regenerating /proc/vmcore entries > after DLPAR memory removal. True. kdump needs to be reloaded after a DLPAR operation to regenerate /proc/vmcore entries. So, kdump-tools.service needs to be restarted after a DLPAR operation.
