Creating namespaces using UEFI System Utilities

IMPORTANT:

Be sure to observe all pop-up messages displayed in UEFI System Utilities that pertain to persistent memory. Failure to follow the instructions in these messages might cause persistent memory data loss.

NOTE:

If you are using HPE Persistent Memory with VMware vSphere, creating namespaces is not required. VMware vSphere automatically creates namespaces upon rebooting.

Namespaces define persistent memory regions on the HPE Persistent Memory modules.
Procedure
  1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Memory Options > Persistent Memory Options.
  2. Select PMM Options > Advanced Options, and make the following selections:

    • Apply Default Namespaces—Enabled or Disabled.

      This selection creates namespace metadata on the next boot for interleave sets that do not already have one. For Linux systems, Hewlett Packard Enterprise recommends using OS tools such as ndctl for this purpose.

    • Delete Namespaces—Immediately deletes any active namespaces.

  3. To save your changes, press the F12 key.
  4. To commit the goal configuration and persistent memory options, reboot the server.
