Cryptographic Erase
You can use the cryptographic erase option to securely erase data present on secure SEDs. Secure data exists on drives even after
the virtual disk is deleted and is thus exposed to threat. Cryptographic erase can be used in the following conditions:
•
To erase data to retire/reuse secure drives.
•
To securely erase data if secure and locked foreign configuration need not be imported.
•
To recover locked drives if the passphrase is lost.
You can perform the cryptographic erase on one or more SED physical disks.
CAUTION: Performing the cryptographic erase task erases all data on the physical disk.
Performing Cryptographic Erase
If the physical disk is part of a virtual disk, remove it from the virtual disk before performing cryptographic erase.
To perform a cryptographic erase:
1.
In the left pane, go to Storage → Physical Disks → Setup.
The Configure Physical Disks page is displayed.
2.
Select the physical disk from which you want to erase the data.
3.
From the Physical Disk Actions drop-down, select Cryptographic Erase and click Apply.
A message is displayed prompting you to confirm the action.
4.
Click Yes to proceed
All data from the selected physical disk is removed.
Applying Virtual Adapter Access Policy To Virtual Disks
Make sure that physical disk drives are installed and the virtual disks are created.
To apply the virtual adapter access policy:
1.
In the left pane, click Chassis Overview → Storage → Virtual Disks → Assign.
2.
On the Assign Virtual Disks page, under the Access Policy for Virtual Adapters section, from the Virtual Adapter <number>
drop-down menu, select Full Access to each physical disk drive.
3.
Click Apply.
You can now assign virtual adapters to server slots. For more information, see the Assigning Virtual Adapters to Slots section in this
User's Guide.
Modifying Virtual Disk Properties Using CMC Web Interface
To modify the virtual disk properties:
1.
In the left pane, click Chassis Overview → Storage → Virtual Disks → Manage.
2.
On the Manage Virtual Disks page, from the Virtual Disk Actions drop-down menu, select one of the following actions, and
then click Apply.
•
Rename
•
Delete
NOTE: If you select Delete, the following message is shown indicating that deleting a virtual disk permanently
deletes data available in that virtual disk.
Deleting the virtual disk removes the virtual disk from the controller's
configuration. Initializing the virtual disk permanently erases data from the
virtual disk.
