10.5 Physical Device Level Operation on Self Encrypting Drives (SEDs)

To perform the physical device level operations on Self Encrypting Drives (SEDs):
  1. In the Enterprise view, select the Physical Device node.
  2. On the ribbon, in the Physical Device group, click Set Properties.

    The Set Properties window opens.

    Graphical user interface, application Description automatically generated
  3. Perform one of the following options:
    • Take SED Ownership: This option takes the ownership of the selected SEDs by selecting the Take SED Ownership check box. Take SED Ownership check box is disabled when the SED is not in Original Factory State (OFS).

      After getting the ownership, the selected SED’s Ownership status changes to “MCHP Owned” and OFS will be set as False. When the controller’s SED Encryption status is “Waiting on Controller Password”, the Take SED Ownership check box gets disabled until the controller password is provided.

    • Revert To Original Factory State (OFS): This option deletes all the user’s data stored in the drive and resets to its factory state. On physical device level, Revert to Original Factory State (OFS) operation can be performed on all SED with Physical Security ID (PSID). If the ownership status is MCHP Owned, then Physical Security ID (PSID) is not a mandatory field. Sometimes ownership status is “MCHP Owned, Foreign”, in this case, Revert to Original Factory State (OFS) operation is not allowed on the respective SED using PSID. When the controller’s SED Encryption status is “Waiting on Controller Password”, the Revert To Original Factory State (OFS) check box gets disabled until controller password is provided. When controller’s SED Encryption status is “Waiting on Mater Key”, the Revert To Original Factory State (OFS) checkcbox gets disabled until the system is rebooted.
    • Import Foreign Self Encrypting Drive (SED): An SED is said to be Foreign, when the SED is owned by MCHP and have a different master key compared to its connected controller. This happens under the following circumstances, when:
      • The SED has migrated from a different controller.
      • The SED has been previously owned by the connected controller but was removed for a period. At that time, the connected controller’s master key has changed.

      This operation converts the Foreign SED to MCHP Owned SED. Only Foreign SED whose Foreign Key matches with that SED will be properly imported. Import Foreign SED has one more text field as “Import Foreign Reset Key”. It gets displayed only when this key is required based on the “Foreign Reset Key Identifier” property. If this property value is other than “Not Applicable”, this option gets displayed.
