Erasing system and user data

NOTE:Erasing system and user data is not supported from iDRAC GUI.
You can erase system components and user data for the following components:
  • BIOS reset to default
  • Embedded Diagnostics
  • Embedded operating system Driver Pack
  • Lifecycle Controller Data
  • iDRAC reset to default
  • Overwrite hard drives that do not support Instant Secure Erase (ISE)
  • Reset controller cache
  • Reset vFLASH
  • Erase Hard Drives, SSDs, and NVMes that support ISE.
  • Clear all operating system applications.

Before performing system erase, ensure that:

  • You have iDRAC Server Control privilege.
  • Lifecycle Controller is enabled.

The Lifecycle Controller Data option erases any content such as the LC Log, configuration database, rollback firmware, factory as-shipped logs, and the configuration information from the FP SPI (or management riser).

NOTE:The Lifecycle Controller log contains the information about the system erase request and any information that is generated when iDRAC restarts. All previous information is removed.
You can delete individual or multiple system components using the SystemErase command: 
racadm systemErase <BIOS | DIAG | DRVPACK | LCDATA | IDRAC >
Where,
  • bios—BIOS reset to default
  • diag—Embedded Diagnostics
  • drvpack—Embedded OS Driver Pack
  • lcdata—Clear the Lifecycle Controller Data
  • idrac—iDRAC reset to default
  • overwritepd—Overwrite hard drives that do not support Instant Secure Erase (ISE)
  • percnvcache—Reset controller cache
  • vflash—Reset vFLASH
  • secureerasepd—Erase Hard Drives, SSDs, and NVMes that support ISE
  • allapps—Clears all operating system applications
NOTE:Secure erase does not erase iDRAC rollback firmware from the partition when the command racadm systemerase lcdata is used.
NOTE: While erasing vFlash, ensure that all partitions on the vFlash card are detached before performing the operation.
NOTE: If SEKM is enabled on the server, then disable SEKM using the racadm sekm disable command before using this command. This can avoid any storage devices being locked out which are secured by iDRAC, if SEKM settings are erased from iDRAC by performing this command.

For more information, see the Integrated Dell Remote Access Controller RACADM CLI Guide .

NOTE:The Dell tech center link appears on the iDRAC UI on Dell branded systems. If you erase system data by using the WSMan command and want the link to appear again, reboot the host manually and wait for CSIOR to run.
NOTE:After you run System Erase, the VDs may still appear. Run CSIOR after System Erase is completed and iDRAC is rebooted.
NOTE:In the latest iDRAC releases, the LCWipe command is deprecated. To perform the system erase operation, run the systemerase command.
