Operating system deployment is the process of installing an operating system on one or more Dell PowerEdge, HPE iLO or Supermicro servers. See Validated hypervisors and operating systems for the hypervisors and operating systems that Bare Metal Orchestrator can deploy.
You can perform the following operations:
- View, create, edit or delete media objects.
- Update the media attributes while creating or editing a media object.
For more information about the CLI commands for media, see the Bare Metal Orchestrator Command Line Interface Reference Guide.
- Install the operating system.
- Verify the operating system installation.
Deployment requirements
The following table lists the minimum free space required on the Bare Metal Orchestrator Global Controller and Worker nodes to deploy the operating system on a single server. Ensure there is enough free space on the Global Controller and at each worker site before installing the operating system.
Operating system | Minimum free space |
ESXi | 10 GB |
openSUSE | 24 GB |
Red Hat Enterprise Linux | 50 GB |
Ubuntu 20.04 LTS | 50 GB |
Wind River® Cloud Platform | 500 GB on each server in the cloud cluster |
To check the available free space on a VM, see Confirm available free space on the node.
For Red Hat Enterprise Linux installations, if a server fails to onboard during the installation process because there is not enough available free space, contact Dell support before attempting to install the operating system again. See Contacting Dell Support for details.
- Navigate to iDRAC -> Configuration -> Virtual media -> Remote File Share 1 -> Directory/File Path and provide the internal NGINX path (idrac-virtualmedia-path.png).
- Manually mount the iso image.
- Disconnect and restart the installation from Bare Metal Orchestrator.
Deployment limitations
The following table describes limitations when installing hypervisors and operating systems on servers:
Item | Limitation |
Red Hat Enterprise Linux installation | Bulk deployment operations are not supported for Red Hat Enterprise Linux. This operating system can only be deployed on one server at a time. |
ESXi installation | The target server must have a visible drive for the installation. Select the volume in the server specification YAML file that you use to install the hypervisor. You can use either the volumeID or the volumeOrder attribute to select the volume for the installation. |
ESXi and Ubuntu installations on HPE iLO servers | The volumeTypeOrder supported is RAID. To add the name of a specific volume that you want to use, follow the same procedure that you use to add a volume name on other servers, such as the Dell PowerEdge server. For more information about RAID configuration attributes, see RAID attribute definitions. |
Operating system deployments on Supermicro servers | Supermicro servers only support RHEL 8.4 and ESXi 7 operating systems. You must install the operating systems onto a PXE device for Supermicro servers. For more information about operating system installation on to a PXE device, see Operating system installation using PXE boot. |
