NVDIMM relocation guidelines
Requirements for relocating NVDIMMs or a set of NVDIMMs when the data must be preserved
- The destination server hardware must match the original server hardware configuration.
- All System Utilities settings in the destination server must match the original System Utilities settings in the original server.
- If NVDIMM-Ns are used with NVDIMM Interleaving ON mode in the original
server, do the following:
Install the NVDIMMs in the same DIMM slots in the destination server.
Install the entire NVDIMM set (all the NVDIMM-Ns on the processor) on the destination server.
This guideline would apply when replacing a system board due to system failure.
If any of the requirements cannot be met during NVDIMM relocation, do the following:Manually back up the NVDIMM-N data before relocating NVDIMM-Ns to another server.
Relocate the NVDIMM-Ns to another server.
Sanitize all NVDIMM-Ns on the new server before using them.
Requirements for relocating NVDIMMs or a set of NVDIMMs when the data does not have to be preserved
If data on the NVDIMM-N or set of NVDIMM-Ns does not have to be preserved, then
- Move the NVDIMM-Ns to the new location and sanitize all NVDIMM-Ns after installing them to the new location. For more information, see NVDIMM sanitization.
Observe all DIMM and NVDIMM population guidelines. For more information, see DIMM and NVDIMM population information.
- Observe the process for removing an NVDIMM.
- Observe the process for installing an NVDIMM.
- Review and configure the system settings for NVDIMMs. For more information, see Configuring the server for NVDIMMs .
