• Security
– Enable Security
Attention: By default, PMEM security is disabled. Before enabling security, make sure all the country
or local legal requirements regarding data encryption and trade compliance are met. Violation could
cause legal issues.
PMEMs can be secured with passphrases. Two types of passphrase protection scope are available for
PMEM:
– Platform: Choose this option to run security operation on all the installed PMEM units at once. A
platform passphrase is stored and automatically applied to unlock PMEMs before operating system
starts running, but the passphrase still has to be disabled manually for secure erase.
Alternatively, enable/disable platform level security with the following commands in OneCLI:
• Enable security:
1. Enable security.
OneCli.exe config set IntelOptanePMEM.SecurityOperation "Enable Security"
--bmc USERID:PASSW0RD@10.104.195.86
2. Set the security passphrase.
OneCli.exe config set IntelOptanePMEM.SecurityPassphrase "123456"
--bmc USERID:PASSW0RD@10.104.195.86
Where 123456 stands for the passphrase.
3. Reboot the system.
• Disable security:
1. Disable security.
OneCli.exe config set IntelOptanePMEM.SecurityOperation "Disable Security"
--bmc USERID:PASSW0RD@10.104.195.86
2. Enter passphrase.
OneCli.exe config set IntelOptanePMEM.SecurityPassphrase "123456"
--bmc USERID:PASSW0RD@10.104.195.86
3. Reboot the system.
– Single PMEM: Choose this option to run security operation on one or more selected PMEM units.
Notes:
• Single PMEM passphrases are not stored in the system, and security of the locked units needs to
be disabled before the units are available for access or secure erase.
• Always make sure to keep records of the slot number of locked PMEMs and corresponding
passphrases. In the case the passphrases are lost or forgotten, the stored data cannot be backed
up or restored, but you can contact Lenovo service for administrative secure erase.
• After three failed unlocking attempts, the corresponding PMEMs enter "exceeded" state with a
system warning message, and the PMEM unit can only be unlocked after the system is rebooted.
To enable passphrase, go to Security ➙ Press to Enable Security.
