Actual results:
After sanitize-dimm operation finished, the security state changed to "disabled", and the key still exists under /etc/ndctl/kerys.
After system reboot, seems the key setup again and the security state changed to "unlocked", I have to manually remove-passphrase to disable the security state.

Here is part of the manual from ndctl sanitize-dimm
"
Additionally, after completion of this command, the security and passphrase for the given NVDIMM will be disabled, and the passphrase and any key material will also be removed from the keyring and the ndctl keys directory at /etc/ndctl/keys
"

Expected results:
