HPE ProLiant DL388 Gen10 - NVDIMM Relocation Guidelines; Recovering Restored Data from an NVDIMM-N DRAM

NIST SP800-88 Guidelines for Media Sanitization (Rev 1, Dec 2014) is available for download from the NIST
website (http://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-88r1.pdf).
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 on page 89.
• Observe all DIMM and NVDIMM population guidelines. For more information, see DIMM and NVDIMM
population information on page 89.
• 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 on page 91.
Recovering restored data from an NVDIMM-N DRAM
CAUTION: Do not remove an NVDIMM when any LEDs on any NVDIMM in the system are illuminated.
Removing an NVDIMM when an LED is illuminated might cause a loss of data.
CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly
grounded before beginning this procedure.
