After DR detach, the total available memory is shrunk by the size of detached memory and the size of detached swap space on the detached disks. The detached swap space on the multipathing device doesn't affect the total available memory size.
Therefore, the total available memory before DR detach must be bigger than the total detached size. And you need to add the same amount of swap space as the total detached size before DR detach so that the system keeps the same amount of available memory after DR detach.
'swap -s' shows the current total available memory size. Please refer to the swap(1M) manual page for more details.
