HPE OneView Redfish Toolkit

This toolkit provides a REST service to answer DMTF's Redfish compliant requests by querying HPE OneView.

HPE OneView is a fresh approach to converged infrastructure management, inspired by the way you expect to work, with a single integrated view of your IT infrastructure.

DMTF's Redfish is an open industry standard specification and schema that specifies a RESTful interface and utilizes JSON and OData to help customers integrate solutions within their existing tool chains.

Installation

Requirements

HPE OneView Redfish Toolkit service relies on Python 3.5 or newer (as long as python3 executable is available) to run and pip3 for dependencies management. A full list of dependencies is available at requirements.txt file. For pyOpenSSL module please make sure to have OpenSSL lib installed in your system.

There should be not problem in using Python 3.4 if your system does not have Python 3.5 available, but we do not guarantee complete compatibility as the test environment is set up on version 3.5.

In order to run tests and documentation generation tox is also needed. General instructions on how to install are available here.

From source

We recommend to run inside a virtual environment. You can create one running:

$ virtualenv env_name_you_choose -p python3.5 # to create a Python3.5 environment, for example
$ source env_name_you_choose/bin/activate # load the environment

Once the environment is loaded, download and uncompress the latest version from releases page, or clone current development version running:

$ git clone https://github.com/HewlettPackard/oneview-redfish-toolkit.git

Then, proceed with:

$ cd oneview-redfish-toolkit # enter the service folder
# edit redfish.conf
$ pip install -r requirements.txt # to install all requirements into the virtual environment
$ ./run.sh    # to launch the service

SDK Documentation

The latest version of the SDK documentation can be found in the SDK Documentation section.

Note: This documentation has been manually updated following the steps found here.

Logging

Logging configuration can be found in logging.conf file. The provided configuration enables INFO level at both console and file output (which will generate a redfish.log file).

Configuration

In order to start up oneview-redfish-toolkit service, there is some mandatory configuration at redfish.conf file to provide as explained below:

• redfish section

  • schema_dir: path to where DTMF's Redfish JSON schemas are stored

  • indent_json: whether JSON objects on answers are indented or not

  • xml_prettify: whether XML objects on answers are indented or not

  • redfish_host: the IP address where redfish service will listen to. Using host = 0.0.0.0 means it will listen to all IP addresses.

  • redfish_port: the TCP port where redfish service will listen to

  • authentication_mode: can be one of: conf or session. In conf mode authentication credentials from the conf file will be used for all requests. In session mode the user must authenticate himself using his own username and password doing a post request to /redfish/v1/SessionService/Sessions, passing the parameters UserName and Password in the body. The user will get an x-auth-token from this operation and all subsequent operations should send this token as a x-auth-token header. The /redfish and /redfish/v1 endpoints can be accessed without authentication. If mode is set to session any other request to endpoints apart from those mentioned above are going to be rejected if they don't send a valid x-auth-token header.

• oneview section

  • ip: HPE OneView's IP or FQDN address

  • api_version: HPE OneView's version. Defaults to 300.

• credentials section

  • username: HPE OneView's username  
  • password: HPE OneView's password

• event_service section

  • DeliveryRetryAttempts: The value of this property shall be the number of retrys attempted for any given event to the subscription destination before the subscription is terminated.  
  • DeliveryRetryIntervalSeconds: The value of this property shall be the interval in seconds between the retry attempts for any given event to the subscription destination.

• ssl section

  • SSLType: How to configure SSL. One of: disabled (no SSL), adhoc (SSL is enabled with self-signed keys generated by the server every time you start the server), self-signed (SSL is enabled with a self-signed cert generated in the certs directory if no files named self-signed.crt and self-signed.key exists in that directory. This will create the certificates on the first run and every time you delete the files and restart the server. The directory certs must exist in the system root directory) certs (SSL is enabled with keys provided by user in the fields below). The default value used is adhoc.  

  • SSLCertFile: The user SSL cert file.

  • SSLKeyFile: The user SSL key file. Should not have a password.

• ssl-cert-defaults section: Defines the values used in the self-signed generated certificate

  • countryName: The name of the country. Required!  

  • stateOrProvinceName: The name of the state or province. Required!

  • localityName: Name of the locality (city for example). Required!

  • organizationName: Name of the organization (company name for example). Required!  

  • organizationalUnitName: Name of the organizational unit (department for example). Required!

  • commonName: FQDN of the server or it's IP address. If not provided will detect de default route IP and use it. Optional.  

  • emailAddress: Email address to contact the responsible for this server/certificate. This is an optional information. Will not be added to certificate if not informed. Optional.

• schemas section

  • ServiceRoot: DTMF's Redfish JSON schema for the Service Root resource  
  • ChassisCollection: DTMF's Redfish JSON schema for Chassis collections  
  • Chassis: DTMF's Redfish JSON schema for Chassis resources  
  • ComputerSystemCollection: DTMF's Redfish JSON schema for Computer Systems collections  
  • ComputerSystem: DTMF's Redfish JSON schema for Computer Systems resources  
  • ManagerCollection: DTMF's Redfish JSON schema for Managers collections  
  • Manager: DTMF's Redfish JSON schema for Manager resources  
  • EventService: DTMF's Redfish JSON schema for the Event Service resource  
  • EventDestination: DTMF's Redfish JSON schema for Event Destination resources  
  • Event: DTMF's Redfish JSON schema for Event objects

Note: HPE OneView' credentials are stored in clear-text. Make sure only authorized users can access this file.

Event Service notes:

Currently, Event Service works only when authentication_mode is set to conf. As it connects directly to HPE OneView SCMB, the toolkit will request OneView to generate SCMB certs and/or download the certs to the correct location. The certs file are: oneview_ca: OneView's CA cert file located at: certs/oneview_ca.pem. scmb_cert: OneView's SCMB Client cert file located at: certs/oneview_scmb.pem. scmb_key: OneView's SCMB Client key file located at: certs/oneview_scmb.key
