SSH host public key of the remote backup server is invalid

Symptom

Unable to verify remote backup configuration due to invalid manually entered SSH host public key.

Cause

Introduced a cut and paste error of the key in the SSH host key field.

Action
  1. Ensure that you did not insert any line breaks when you cut and pasted into the field.
  2. Retry the operation or use a different key.
  3. Use utilities to capture the host key from the remote backup server.
    1. openssh has a utility to capture the host key that is commonly found on most Linux distributions.
    2. ssh-keyscan <host> command provides the available ssh host keys.
    3. Select the appropriate supported algorithm and length as specified in the Ciphers for secure connection between HPE OneView and backup server.
    4. Verify the host key fingerprint with the administrator of the remote backup server.
