Setting The Nvdimm-N Sanitize/Erase On Next Reboot Policy; Nvdimm-N Data Integrity Checking - HPE ProLiant Gen9 User Manual

Setting the NVDIMM-N Sanitize/Erase on Next Reboot Policy

Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > System Options > Memory Operations > NVDIMM Memory Options > NVDIMM-N Sanitize/
Erase on Next Reboot Policy and press Enter.
The following alert is displayed.
IMPORTANT: Sanitizing/Erasing an NVDIMM-N will result in the loss of ALL user
data saved in the NVDIMM-N. It is strongly recommended that manual backup of
all user data in the NVDIMM-N(s) be performed before sanitizing/erasing the
NVDIMM-N(s).
2. Press any key to proceed.
3. Select one of the following menu items. For more information about each selection, see the HPE 8GB
NVDIMM User Guide for HPE ProLiant Gen9 Servers..
a. Sanitize/Erase and Boot to Operating System
b. Sanitize/Erase and Power System Off
c. Sanitize/Erase and Boot to System Utilities
4. Select one of the following menu items based on the NVDIMM-Ns to be sanitized/erased:
a. Sanitize/Erase all NVDIMM-N in the System—Use this option for major system reconfigurations.
b. Sanitize/Erase all NVDIMM-N on Processor 1 —Use this option when all the NVDIMM-Ns on a
processor must be sanitized together, such as when enabling NVDIMM-N Memory Interleaving.
c. Sanitize/Erase Processor 1 DIMM X —(Available only when NVDIMM-N Memory Interleaving is
disabled) Use this option for adding individual NVDIMM-Ns, or for using an NVDIMM-N again after
errors occur.
d. Sanitize/Erase all NVDIMM-N on Processor 2 —Use this option when all the NVDIMM-Ns on a
processor must be sanitized together, such as when enabling NVDIMM-N Memory Interleaving.
e. Sanitize/Erase Processor 2 DIMM X —(Available only when NVDIMM-N Memory Interleaving is
disabled) Use this option for adding individual NVDIMM-Ns, or for using an NVDIMM-N again after
errors occur.
When enabled, all user data in the selected NVDIMM-N is erased on the next reboot. The Sanitize
NVDIMM-N scope selections are available only after a sanitize policy is selected.
5. Press F10.
6. Reboot the server.
The server will reboot multiple times as part of the sanitize process. POST messages will also display to
indicate the NVDIMM-Ns that are being sanitized.

NVDIMM-N Data Integrity Checking

When this option is enabled (the default setting), the system checks each NVDIMM-N during system boot to
determine the integrity of the data stored on the NVDIMM-N. If any data cannot be read properly, the system
maps out the NVDIMM-N so that it cannot be used by the operating system. When this option is disabled, and
