8. Click Next.
   A message stating the removal or addition of the NVDIMM node or battery, with the node and slot numbers, is displayed on the Resource Groups page. The status of the resource group and the individual node is "In Progress". The log details are also displayed in the Recent Activity section on the right side of the page.

   After the node is replaced, the host and SVM are turned off. After the physical replacement of the node and the battery, the status of the host and node on the Resource Groups page display service mode.
