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.

CAUTION:
Failure to properly handle DIMMs can damage the DIMM components and the system board connector. For more information, see the DIMM handling guidelines in the troubleshooting guide for your product on the Hewlett Packard Enterprise website:

When the NVDIMM-N DRAM contains the only copy of restored data, perform the following procedure to recover the information:

Procedure
  1. Copy the data from the NVDIMM to some other storage device (such as SSD, HDD, or another NVDIMM) as soon as possible (before cold reset or power loss).
  2. Power down the server.
  3. Extend or remove the server.
  4. Remove the access panel.
  5. Remove all components necessary to access the server DIMM slots and the HPE Smart Storage Battery.

    For more information, see the server maintenance and service guide on the Hewlett Packard Enterprise website (http://www.hpe.com/info/enterprise-docs).

  6. Observe the NVDIMM LEDs. Do not remove an NVDIMM when any NVDIMM LED in the system is illuminated.
  7. Remove the NVDIMM-N.
  8. Install a replacement NVDIMM-N.
  9. Install any components removed to access the DIMM slots and the HPE Smart Storage Battery.
  10. Install the access panel.
  11. Install the server in the rack.
  12. Power up the server.
  13. Sanitize the replacement NVDIMM.
  14. Copy the data from the storage device to the NVDIMM-N.
