This HPE Horizon plug-in is provided to help administrators better manage their OpenStack
Cinder environment and HPE 3PAR StoreServ backend storage arrays.
The main functions of this plug-in are:
Validate OpenStack Cinder configuration files to ensure they are properly specified.
Provide detailed views of all HPE Storage Arrays configured for Cinder backend
storage.
Provide a direct link between OpenStack volumes and their associated detail views
in the HPE storage management console.
Query Nova nodes for active Volume Paths. This information can be used to validate storage
volume attachments to instance nodes.
The HPE Horzion plug-in consists of multiple tabs, each described in detail below:
Configuration
Use this panel to configure all of the features of the HPE Storage Horizon plug-in
tool. This includes:
Cinder node registration
Register Cinder nodes by supplying their node addresses, SSH
credentials to access the node, and the path to the "cinder.conf"
configuration file. This information is required to
perform diagnostic tests and for discovering backend HPE storage arrays.
Nova node registration (Optional)
Register Nova nodes by supplying their node addresses and the SSH
credentials to access them. This information is required to perform diagnostic tests.
Links between Cinder backends and HPE SSMC instances
Configure links between Cinder backends and HPE 3PAR StoreServ Management Console (SSMC)
instances. Once created, any volume or snapshot hosted on the Cinder backend will have
additional actions available in the Horizon Admin "Volumes" panel tables, including the
ability to link directly to its associated volume/snapshot details panel in HPE SSMC.
This feature is especially critical because volume and snapshot names assigned in Horizon
are not the names used when creating the object on the back-end storage array. This feature
provides the only means to link the two names together.
Diagnostic Tests
Use this panel to perform diagnostic tests on registered Cinder and Nova nodes.
For Cinder nodes, the
test consists of validating HPE related "cinder.conf" file settings, and verifying that the
HPE 3PAR driver and other required software utilies are installed.
For Nova nodes, the
test checks for the installation of required software utilities.
Storage Arrays
Use this panel to view details on all discovered HPE storage arrays. Details include:
Array model type, serial number, OS and REST API (WSAPI) versions
Array license information and how each relates to OpenStack features
Storage pool capabilities
Volume Paths
Use this panel to perform volume path queries on all registered Nova nodes.
For each registered Nova node, the query will return all active volume paths along with any
associated volume names and ids. Results of the queries will be saved and can be compared
against previous queries using the panels "Diff" feature. This can be very useful, for example,
in determining if volume migration was completed successfully.
Where to begin...
To verify your OpenStack Cinder and Nova environment and discover HPE 3PAR backend
storage arrays:
Go to the "Configuration" tab and register all your Cinder and Nova nodes.
Click the "Validate SSH Credentials" button to validate the registration
information you entered is correct.
Go to the "Diagnostic Tests" tab and run diagnostic tests on all of your
registered Cinder and Nova nodes. An added feature of running diagnostic tests on
Cinder nodes is the discovery of backend storage arrays.
Go to the "Storage Arrays" tab to see what HPE 3PAR StoreServ arrays were discovered
by the running of the Cinder diagnostic tests.
To add direct links from OpenStack volumes to associated HPE 3PAR SSMC detailed
views:
Go to the "Configuration" tab and add links between Cinder backends and
instances of HPE 3PAR SSMC.
Go to the Admin -> Volumes panel to view additional actions associated
with all volumes that were assigned to the Cinder backend specified in the
previous step.
Select one of the new actions to launch directly to the volumes
associated views in HPE 3PAR SSMC.
