Users Guide

The RACADM SystemErase sub-command includes options for the following categories:
● The SecureErasePD option cryptographically erases all the secure erase drives.
● The OverwritePD option overwrites data on all drives.
Before performing SystemErase, use the following command to check the erase capability of all physical disks for a server:
# racadm storage get pdisks –o –p SystemEraseCapability
To erase ISE and SED drives, use this command:
# racadm systemerase –secureerasepd
To erase overwrite erase drives, use the following command:
# racadm systemerase -overwritepd
NOTE: RACADM SystemErase removes all the virtual disks from the physical disks that are erased by the above commands.
NOTE: RACADM SystemErase causes the server to restart in order to perform the erase operations.
NOTE: Individual PCIe SSD or SED devices can be erased using the iDRAC GUI or RACADM. For more information, see the
Erasing PCIe SSD device data and the Erasing SED device data section.
For information on the System Erase function within the Lifecycle Controller GUI, see the Lifecycle Controller User's Guide
available at www.dell.com/idracmanuals .
Erasing SED device data
NOTE:
This operation is not supported when SED device is a part of a Virtual Disk. The target SED device must be removed
from the virtual disk prior to performing device erase.
Cryptographic Erase permanently erases all data present on the disk. Performing a Cryptographic Erase on an SED overwrites all
blocks and results in permanent loss of all data on the SED. During Cryptographic Erase, the host is unable to access the SED.
SED device erase can be performed either in real time or be applied after a system reboot.
If the system reboots or experiences a power loss during cryptographic erase, the operation is canceled. You must reboot the
system and restart the process.
Before erasing SED device data, ensure that:
● Lifecycle Controller is enabled.
● You have Server Control and Login privileges.
● Selected SED drive is not part of a virtual disk.
NOTE:
● Erasing SEDs can be performed either as a real time or as a staged operation.
● After the SED drive is erased, it may still be displayed as active within the OS due to data caching. If this occurs, reboot
the OS and the erased SED drive will no longer be displayed or report any data.
● Cryptographic erase feature is supported for SEDs for 14th generation PowerEdge servers.
Erasing SED device data using web interface
To erase the data on the SED device:
1. In the iDRAC Web interface, go to Storage > Overview > Physical Disks.
The Physical Disk page is displayed.
2. From the Controller drop-down menu, select the controller to view the associated SEDs.
3. From the drop-down menus, select Cryptographic Erase for one or more SEDs.
If you have selected Cryptographic Erase and you want to view the other options in the drop-down menu, then select
Action and then click the drop-down menu to view the other options.
4. From the Apply Operation Mode drop-down menu, select one of the following options:
● Apply Now — Select this option to apply the actions immediately with no system reboot required.
