The installer now uses the settings from your existing Ceph Storage cluster in your new Red hat Enterprise Linux OpenStack Platform environment.

7.7. Configuring Fencing on High-Availabilit y Nodes

Configure fencing on hosts that have been assigned to the controller deployment role in deployments where you selected Hi g h Avai l abi l i ty C o ntro l l ers / C o mpute in the D epl o yment Setti ng s step when creating that deployment.

5. If the message Fenci ng i s d i sabl ed . T o enabl e, fi rst yo u need to ad d a BMC i nterface to the Ho st is displayed, you must manually configure the details of a baseboard management controller network interface attached to the host:

a. Click the Netwo rk tab. b. Click Ad d Interface. c. Select BMC from the T ype list.

d. Enter the MAC address for the network interface controller in the MAC ad d ress field. e. Click the Fenci ng tab.

6. Select Enabl e Fenci ng . 7. Select IP MI from the T ype list.

8. Enter the IP address of the fencing device in the IP Ad d ress field.

9. Enter the name of the IPMI user on the fencing device in the Username field.

10. Enter the password by which to authenticate the above user in the P asswo rd field. 11. Select Expo se Lanpl us to use the l anpl us interface.

12. If you selected the Expo se Lanpl us check box, enter any options in the Lanpl us O pti o ns field.

13. Click Submi t.

You have configured fencing for the host, and the settings you specified are applied to the host when you provision RHEL OpenStack Platform.

7.8. Provisioning Red Hat Ent erprise Linux OpenSt ack Plat form

When you are ready to provision the RHEL OpenStack Platform environment, click D epl o y to open the deployment confirmation screen.

Fig u re 7.13. T h e d ep lo ymen t co n f irmat io n screen

Note

Clicking D epl o y registers the nodes and consumes entitlements. If you perform multiple deployments, you may need to first remove the existing environment from Subscri pti o n Manag er, if applicable.

Confirm the OpenStack services to be provisioned and click D epl o y.

Hosts assigned to roles in the deployment are moved to the pro d ucti o n environment, which contains the Puppet classes required to provision RHEL OpenStack Platform. The hosts are provisioned in accordance with the role to which they are assigned in the deployment and the deployment screen shows the progress of provisioning.

7.9. Monit oring Progress of t he Deployment

There are several methods to monitor the progress of your deployment. This section gives a high level overview of each of these methods.

Progress Bar

The Progress Bar on the deployment screen provides an overall indicator of the deployment progress, including the percentage of completion for the different node types deployed.

T asks

The T asks page displays a list of details about current tasks being run by the installer. You can access the T asks page at any time from anywhere in the user interface by clicking Mo n it o r → T asks. You can also access the task for your deployment by clicking Sho w mo re d etai l s under the progress bar.

The T asks page is useful for indentifying specific progress on your deployment including any errors that have stopped your deployment.

Dynflow Console

The D ynfl o w C o nso l e shows the subtasks for a particular task and the progress on each. This can include subtasks such as building the host's operating system, or deployment and configuration of the OpenStack environment. Access the D ynfl o w C o nso l e from any T asks page.

Report s

The R epo rts page displays a list of reports of Puppet runs executed on the hosts that the installer manages. You can access this page at any time from anywhere in the user interface by clicking Mo n it o r → Rep o rt s. You can also view all reports for a specific host by navigating to Ho st s → All Ho st s → [ Ho st n ame] → Rep o rt s.

Fig u re 7.14 . T h e Rep o rt s p ag e

The reports table displays a list of the number of actions performed on individual hosts during a report interval. The time at which a report was collected is displayed in the Last repo rt column, and actions are divided into a number of categories as outlined below:

Appl i ed : The number of changes that were applied to resources on the host, such as files, directories, or user accounts.

R estarted : The number of resources, such as services, that were restarted.

Fai l ed : The number of actions that were executed but did not complete successfully.

R estart Fai l ures: The number of resources, such as services, that were scheduled to restart but did not restart successfully.

Ski pped : The number of actions that were scheduled, but were skipped due to a problem scheduling the Puppet run.

P end i ng : The number of actions that were scheduled to be applied, but had not yet been performed at the time the report was collected.

7.10. Complet ing Deployment for an Advanced Environment

After you have provisioned your RHEL OpenStack Platform environment, the installer provides a list of details for that environment such as service passwords and the location of the Horizon

dashboard.

1. Click O p en St ack In st aller → Dep lo ymen t s.

2. Click the name of a deployment you have provisioned. 3. Review the details of the deployment.

4. Optionally, click the Access al l d etai l s button to display the Al l d etai l s window, which displays a list of the passwords for all services in your environment.

A final step in the configuration of your advanced environment requires you to create your Ceph Storage Cluster. The deployed Ceph Storage Nodes (OSD) already have configuration files stored in /etc/ceph that help connect to your RHEL OpenStack Platform environment. Use these nodes to create your Ceph Storage Cluster. Consult your Ceph Storage Cluster documentation for details on how to install packages and finalize the configuration of the cluster.

Access the RHEL OpenStack Platform user interface with a web browser. Replace HOSTNAME with the host name or IP address of the server acting as the controller:

https://HOSTNAME/dashboard/ HTTP

http://HOSTNAME/dashboard/

When prompted, log in using the credentials of the ad mi n user. To begin using the OpenStack deployment, see the Administration User Guide and Cloud Administrator Guide.
