CLI Guide

• diag—To erase embedded diagnostics.
• drvpack—To erase embedded OS driver pack.
• idrac—To reset the iDRAC to default.
• lcdata—To erase Lifecycle Controller data.
• allaps—To reset all apps.
• secureerasepd—To erase the physical disk. This supports SED, NVMe drives, and PCIe cards
• overwritepd—To overwrite physical disk. This supports SAS and SATA drives.
• percnvcache—To erase NV cache.
• vflash—To erase vFlash.
• nvdimm—To erase all NonVolatileMemory.
NOTE: When BIOS is selected for System Erase, the server is turned off and the iDRAC is reset at
the end of the Automated Task Application. To complete the process of BIOS reset, the server
power must be restored. When the server is turned on, during POST, the BIOS completes the
process of resetting to the default properties. At the completion of the reset process, the server is
again turned off. Resetting the BIOS also includes the erasing of BIOS-related nonvolatile settings
that are used by the OS and embedded in the UEFI applications.
NOTE: When the racadm systemerase command is executed, the iDRAC will take the following
actions if the:
• Server is powered off—it is powered on.
• Server is powered on—a graceful system reboot will be executed.
• ACPI is enabled on the server— a graceful shutdown occurs within a minute or two.
• ACPI is not enabled—a forced shutdown occurs and it may require up to ten minutes to
complete.
Following the server reboot, the Lifecycle Controller will execute the System Erase job to carry out
the requested actions. All actions performed by the System Erase operations are recorded to the
Lifecycle Log, including details of all devices erased. When these actions are completed, the server
will be powered off and remain in this state, allowing service personnel to perform any needed
posterase actions such as drive removal or hardware reconfiguration. When the server is powered on
to return to service, the Lifecycle Controller will collect the system inventory and reflect any
hardware or firmware changes made after the System Erase.
