Ready-State (BIOS, RAID)

Note

Ready-state configuration currently works only with Dell DRAC machines.

Ready-state configuration can be used to prepare bare-metal resources for deployment. It includes BIOS and RAID configuration based on a predefined profile.

To define the target BIOS and RAID configuration for a deployment profile, you need to create a JSON-like <profile>.cmdb file in /etc/ahc-tools/edeploy. The configuration will be applied only to nodes that match the <profile>.specs rules.

Define the target BIOS configuration

To define a BIOS setting, list the name of the setting and its target value:

[
    {
        'bios_settings': {'ProcVirtualization': 'Enabled'}
    }
]

Define the target RAID configuration

The RAID configuration can be defined in 2 ways: either by listing the IDs of the physical disks, or letting Ironic assign physical disks to the RAID volume.

By providing a list of physical disk IDs the following attributes are required: controller, size_gb, raid_level and the list of physical_disks. controller should be the FQDD of the RAID controller assigned by the DRAC card. Similarly, the list of physical_disks should be the FQDDs of physical disks assigned by the DRAC card. An example:

[
    {
        'logical_disks': [
            {'controller': 'RAID.Integrated.1-1',
             'size_gb': 100,
             'physical_disks': [
                 'Disk.Bay.0:Enclosure.Internal.0-1:RAID.Integrated.1-1',
                 'Disk.Bay.1:Enclosure.Internal.0-1:RAID.Integrated.1-1',
                 'Disk.Bay.2:Enclosure.Internal.0-1:RAID.Integrated.1-1'],
             'raid_level': '5'},
        ]
    }
]

By letting Ironic assign physical disks to the RAID volume, the following attributes are required: controller, size_gb, raid_level and the number_of_physical_disks. controller should be the FQDD of the RAID controller assigned by the DRAC card. An example:

[
    {
        'logical_disks': [
            {'controller': 'RAID.Integrated.1-1',
             'size_gb': 50,
             'raid_level': '1',
             'number_of_physical_disks': 2},
        ]
    }
]

Complete example for a `control.cmdb`

[
    {
        'bios_settings': {'ProcVirtualization': 'Enabled'},
        'logical_disks': [
            {'controller': 'RAID.Integrated.1-1',
             'size_gb': 50,
             'raid_level': '1',
             'number_of_physical_disks': 2,
             'disk_type': 'hdd',
             'interface_type': 'sas',
             'volume_name': 'root_volume',
             'is_root_volume': True},
            {'controller': 'RAID.Integrated.1-1',
             'size_gb': 100,
             'physical_disks': [
                'Disk.Bay.0:Enclosure.Internal.0-1:RAID.Integrated.1-1',
                'Disk.Bay.1:Enclosure.Internal.0-1:RAID.Integrated.1-1',
                'Disk.Bay.2:Enclosure.Internal.0-1:RAID.Integrated.1-1'],
             'raid_level': '5',
             'volume_name': 'data_volume1'}
        ]
    }
]

Trigger the ready-state configuration

Continue with matching the nodes to profiles as described in profile_matching.

Then trigger the BIOS and RAID configuration based on the matched deployment profile:

instack-ironic-deployment --configure-nodes
