Bare Metal Provisioning (BMP) - Config | 23
9. Integrity of the files being downloaded by BMP will be verified using SHA256/MD5 hash. For
each files, the relevant filename.sha256 or filename.md5 should be present in the same location,
where the file is present.
a When FIPS mode is disabled,
• If both filename.sha256 and filename.md5 are not present, then the image
will be downloaded without any type of validation.
• If both filename.sha256 and filename.md5 are present, SHA256 validation
is given the highest priority compared to MD5 validation.
• If filename.sha256 or filename.md5 alone is present, then the corresponding
type of validation will be done.
b When FIPS mode is enabled,
• The MD5 based validation will never be used. BMP checks only for the
filename.sha256 and not the filename.md5.
• If the filename.sha256 is present, it will use the SHA256 based validation or
else the image will be downloaded without SHA256 validation.
