5.1.6 DR Operation During High Load

Even if kernel memory does not exist in the memory on the system board to be separated, separation may fail in a state of high load. This is because a timeout may occur in release (saving the memory of the system board to be separated on the disk by paging) processing of the memory if too many pages are locked in a state of high load. Perform DR operation in a state of low load.

In addition, a specification for not using any memory on a system board to be detached is available. (See the Kernel memory allocation option in "Dynamic Reconfiguration User's Guide".) This specification ensures the detachment of a system board.
