Send NVM Express FormatNVM Admin Command
|
|
|
|
The Format NVM command is used to low level format the NVM media. This command is used by
|
|
the host to change the LBA data size and/or metadata size.
|
|
|
|
A low level format may destroy all data and metadata associated with all namespaces or only
|
|
the specific namespace associated with the command (refer to the Format NVM Attributes field
|
|
in the Identify Controller data structure).
|
|
|
|
After the Format NVM command successfully completes, the controller shall not return any user
|
|
data that was previously contained in an affected namespace.
|
|
|
|
@param[in] This Indicates a pointer to the calling context (Block IO Protocol)
|
|
@param[in] NamespaceId The NVM Express namespace ID for which a device path node is to be
|
|
allocated and built. Caller must set the NamespaceId to zero if the
|
|
device path node will contain a valid UUID.
|
|
@param[in] Ses Secure Erase Setting (SES) value
|
|
- 000b: No secure erase operation requested
|
|
- 001b: User Data Erase
|
|
- 010b: Cryptographic Erase
|
|
- 011b to 111b: Reserved
|
|
@param[in] Flbas New LBA size (in terms of LBA Format size Index (bits 3:0) in NamespaceData).
|
|
If this param is 0 (NULL), then use existing LBA size.
|
|
|
|
@retval EFI_SUCCESS The device formatted correctly.
|
|
@retval EFI_WRITE_PROTECTED The device can not be formatted due to write protection.
|
|
@retval EFI_DEVICE_ERROR The device reported an error while performing the format.
|
|
@retval EFI_NO_MEDIA There is no media in the device.
|
|
@retval EFI_MEDIA_CHNAGED The MediaId does not matched the current device.
|
|
@retval EFI_INVALID_PARAMETER The format request contains parameters that are not valid.

Erase, Crypto Erase, and Overwrite.
