iRMC driver¶

Overview¶

The iRMC driver enables control FUJITSU PRIMERGY via ServerView Common Command Interface (SCCI). Support for FUJITSU PRIMERGY servers consists of the irmc hardware type and a few hardware interfaces specific for that hardware type.

Prerequisites¶

Install python-scciclient and pysnmp packages:

$ pip install "python-scciclient>=0.7.2" pysnmp

Hardware Type¶

The irmc hardware type is available for FUJITSU PRIMERGY servers. For information on how to enable the irmc hardware type, see Enabling hardware types.

Hardware interfaces¶

The irmc hardware type overrides the selection of the following hardware interfaces:

bios
Supports irmc and no-bios. The default is irmc.
boot
Supports irmc-virtual-media, irmc-pxe, and pxe. The default is irmc-virtual-media. The irmc-virtual-media boot interface enables the virtual media based deploy with IPA (Ironic Python Agent).

Warning

We deprecated the pxe boot interface when used with irmc hardware type. Support for this interface will be removed in the future. Instead, use irmc-pxe.
console
Supports ipmitool-socat, ipmitool-shellinabox, and no-console. The default is ipmitool-socat.
inspect
Supports irmc, inspector, and no-inspect. The default is irmc.

Note

Ironic Inspector needs to be present and configured to use inspector as the inspect interface.
management
Supports only irmc.
power
Supports irmc, which enables power control via ServerView Common Command Interface (SCCI), by default. Also supports ipmitool.
raid
Supports irmc, no-raid and agent. The default is no-raid.

For other hardware interfaces, irmc hardware type supports the Bare Metal reference interfaces. For more details about the hardware interfaces and how to enable the desired ones, see Enabling hardware interfaces.

Here is a complete configuration example with most of the supported hardware interfaces enabled for irmc hardware type.

[DEFAULT]
enabled_hardware_types = irmc
enabled_bios_interfaces = irmc
enabled_boot_interfaces = irmc-virtual-media,irmc-pxe
enabled_console_interfaces = ipmitool-socat,ipmitool-shellinabox,no-console
enabled_deploy_interfaces = direct
enabled_inspect_interfaces = irmc,inspector,no-inspect
enabled_management_interfaces = irmc
enabled_network_interfaces = flat,neutron
enabled_power_interfaces = irmc
enabled_raid_interfaces = no-raid,irmc
enabled_storage_interfaces = noop,cinder
enabled_vendor_interfaces = no-vendor,ipmitool

Here is a command example to enroll a node with irmc hardware type.

baremetal node create \
   --bios-interface irmc \
   --boot-interface irmc-pxe \
   --deploy-interface direct \
   --inspect-interface irmc  \
   --raid-interface irmc

Node configuration¶

Configuration via `driver_info`¶

Each node is configured for irmc hardware type by setting the following ironic node object’s properties:
- driver_info/irmc_address property to be IP address or hostname of the iRMC.
- driver_info/irmc_username property to be username for the iRMC with administrator privileges.
- driver_info/irmc_password property to be password for irmc_username.
Note

Fujitsu server equipped with iRMC S6 2.00 or later version of firmware disables IPMI over LAN by default. However user may be able to enable IPMI via BMC settings. To handle this change, irmc hardware type first tries IPMI and, if IPMI operation fails, irmc hardware type uses Redfish API of Fujitsu server to provide Ironic functionalities. So if user deploys Fujitsu server with iRMC S6 2.00 or later, user needs to set Redfish related parameters in driver_info.
- driver_info/redifsh_address property to be IP address or hostname of the iRMC. You can prefix it with protocol (e.g. https://). If you don’t provide protocol, Ironic assumes HTTPS (i.e. add https:// prefix). iRMC with S6 2.00 or later only support HTTPS connection to Redfish API.
- driver_info/redfish_username to be user name of iRMC with administrative privileges
- driver_info/redfish_password to be password of redfish_username
- driver_info/redfish_verify_ca accepts values those accepted in driver_info/irmc_verify_ca
- driver_info/redfish_auth_type to be one of basic, session or auto
If port in [irmc] section of /etc/ironic/ironic.conf or driver_info/irmc_port is set to 443, driver_info/irmc_verify_ca will take effect:

driver_info/irmc_verify_ca property takes one of 4 value (default value is True):
- True: When set to True, which certification file iRMC driver uses is determined by requests Python module.
  
  Value of driver_info/irmc_verify_ca is passed to verify argument of functions defined in requests Python module. So which certification will be used is depend on behavior of requests module. (maybe certification provided by certifi Python module)
- False: When set to False, iRMC driver won’t verify server certification with certification file during HTTPS connection with iRMC. Just stop to verify server certification, but does HTTPS.
  
  Warning
  
  When set to False, user must notice that it can result in vulnerable situation. Stopping verification of server certification during HTTPS connection means it cannot prevent Man-in-the-middle attack. When set to False, Ironic user must take enough care around infrastructure environment in terms of security. (e.g. make sure network between Ironic conductor and iRMC is secure)
- string representing filesystem path to directory which contains certification file: In this case, iRMC driver uses certification file stored at specified directory. Ironic conductor must be able to access that directory. For iRMC to recognize certification file, Ironic user must run openssl rehash <path_to_dir>.
- string representing filesystem path to certification file: In this case, iRMC driver uses certification file specified. Ironic conductor must have access to that file.
The following properties are also required if irmc-virtual-media boot interface is used:
- driver_info/deploy_iso property to be either deploy iso file name, Glance UUID, or Image Service URL.
- instance info/boot_iso property to be either boot iso file name, Glance UUID, or Image Service URL. This is used with the ramdisk deploy interface.
Note

The deploy_iso and boot_iso properties used to be called irmc_deploy_iso and irmc_boot_iso accordingly before the Xena release.
The following properties are also required if irmc inspect interface is enabled and SNMPv3 inspection is desired.
- driver_info/irmc_snmp_user property to be the SNMPv3 username. SNMPv3 functionality should be enabled for this user on iRMC server side.
- driver_info/irmc_snmp_auth_password property to be the auth protocol pass phrase. The length of pass phrase should be at least 8 characters.
- driver_info/irmc_snmp_priv_password property to be the privacy protocol pass phrase. The length of pass phrase should be at least 8 characters.

Configuration via `properties`¶

Each node is configured for irmc hardware type by setting the following ironic node object’s properties:
- properties/capabilities property to be boot_mode:uefi if UEFI boot is required, or boot_mode:bios if Legacy BIOS is required. If this is not set, default_boot_mode at [default] section in ironic.conf will be used.
- properties/capabilities property to be secure_boot:true if UEFI Secure Boot is required. Please refer to UEFI Secure Boot Support for more information.

Configuration via `ironic.conf`¶

All of the nodes are configured by setting the following configuration options in the [irmc] section of /etc/ironic/ironic.conf:
- port: Port to be used for iRMC operations; either 80 or 443. The default value is 443. Optional.
  
  Note
  
  Since iRMC S6 2.00, iRMC firmware doesn’t support HTTP connection to REST API. If you deploy server with iRMS S6 2.00 and later, please set port to 443.
  
  irmc hardware type provides verify_step named verify_http_https_connection_and_fw_version to check HTTP(S) connection to iRMC REST API. If HTTP(S) connection is successfully established, then it fetches and caches iRMC firmware version. If HTTP(S) connection to iRMC REST API failed, Ironic node’s state moves to enroll with suggestion put in log message. Default priority of this verify step is 10.
  
  If operator updates iRMC firmware version of node, operator should run cache_irmc_firmware_version node vendor passthru method to update iRMC firmware version stored in driver_internal_info/irmc_fw_version.
- auth_method: Authentication method for iRMC operations; either basic or digest. The default value is basic. Optional.
- client_timeout: Timeout (in seconds) for iRMC operations. The default value is 60. Optional.
- sensor_method: Sensor data retrieval method; either ipmitool or scci. The default value is ipmitool. Optional.
The following options are required if irmc-virtual-media boot interface is enabled:
- remote_image_share_root: Ironic conductor node’s NFS or CIFS root path. The default value is /remote_image_share_root.
- remote_image_server: IP of remote image server.
- remote_image_share_type: Share type of virtual media, either NFS or CIFS. The default is CIFS.
- remote_image_share_name: share name of remote_image_server. The default value is share.
- remote_image_user_name: User name of remote_image_server.
- remote_image_user_password: Password of remote_image_user_name.
- remote_image_user_domain: Domain name of remote_image_user_name.
The following options are required if irmc inspect interface is enabled:
- snmp_version: SNMP protocol version; either v1, v2c or v3. The default value is v2c. Optional.
- snmp_port: SNMP port. The default value is 161. Optional.
- snmp_community: SNMP community required for versions v1 and v2c. The default value is public. Optional.
- snmp_security: SNMP security name required for version v3. Optional.
- snmp_auth_proto: The SNMPv3 auth protocol. If using iRMC S4 or S5, the valid value of this option is only sha. If using iRMC S6, the valid values are sha256, sha384 and sha512. The default value is sha. Optional.
- snmp_priv_proto: The SNMPv3 privacy protocol. The valid value and the default value are both aes. We will add more supported valid values in the future. Optional.
  
  Warning
  
  We deprecated the snmp_security option when use SNMPv3 inspection. Support for this option will be removed in the future. Instead, set driver_info/irmc_snmp_user parameter for each node if SNMPv3 inspection is needed.

Override `ironic.conf` configuration via `driver_info`¶

Each node can be further configured by setting the following ironic node object’s properties which override the parameter values in [irmc] section of /etc/ironic/ironic.conf:
- driver_info/irmc_port property overrides port.
- driver_info/irmc_auth_method property overrides auth_method.
- driver_info/irmc_client_timeout property overrides client_timeout.
- driver_info/irmc_sensor_method property overrides sensor_method.
- driver_info/irmc_snmp_version property overrides snmp_version.
- driver_info/irmc_snmp_port property overrides snmp_port.
- driver_info/irmc_snmp_community property overrides snmp_community.
- driver_info/irmc_snmp_security property overrides snmp_security.
- driver_info/irmc_snmp_auth_proto property overrides snmp_auth_proto.
- driver_info/irmc_snmp_priv_proto property overrides snmp_priv_proto.

Optional functionalities for the `irmc` hardware type¶

UEFI Secure Boot Support¶

The hardware type irmc supports secure boot deploy, see UEFI secure boot mode for details.

Warning

Secure boot feature is not supported with pxe boot interface.

Node Cleaning Support¶

The irmc hardware type supports node cleaning. For more information on node cleaning, see Node cleaning.

Supported Automated Cleaning Operations¶

The automated cleaning operations supported are:

restore_irmc_bios_config: Restores BIOS settings on a baremetal node from backup data. If this clean step is enabled, the BIOS settings of a baremetal node will be backed up automatically before the deployment. By default, this clean step is disabled with priority 0. Set its priority to a positive integer to enable it. The recommended value is 10.

Warning

pxe boot interface, when used with irmc hardware type, does not support this clean step. If uses irmc hardware type, it is required to select irmc-pxe or irmc-virtual-media as the boot interface in order to make this clean step work.

Configuration options for the automated cleaning steps are listed under [irmc] section in ironic.conf

clean_priority_restore_irmc_bios_config = 0

For more information on node automated cleaning, see Automated cleaning

Boot from Remote Volume¶

The irmc hardware type supports the generic PXE-based remote volume booting when using the following boot interfaces:

irmc-pxe
pxe

In addition, the irmc hardware type supports remote volume booting without PXE. This is available when using the irmc-virtual-media boot interface. This feature configures a node to boot from a remote volume by using the API of iRMC. It supports iSCSI and FibreChannel.

Configuration¶

In addition to the configuration for generic drivers to remote volume boot, the iRMC driver requires the following configuration:

It is necessary to set physical port IDs to network ports and volume connectors. All cards including those not used for volume boot should be registered.

The format of a physical port ID is: <Card Type><Slot No>-<Port No> where:
- <Card Type>: could be LAN, FC or CNA
- <Slot No>: 0 indicates onboard slot. Use 1 to 9 for add-on slots.
- <Port No>: A port number starting from 1.
These IDs are specified in a node’s driver_info[irmc_pci_physical_ids]. This value is a dictionary. The key is the UUID of a resource (Port or Volume Connector) and its value is the physical port ID. For example:
```
{
  "1ecd14ee-c191-4007-8413-16bb5d5a73a2":"LAN0-1",
  "87f6c778-e60e-4df2-bdad-2605d53e6fc0":"CNA1-1"
}
```
It can be set with the following command:
```
baremetal node set $NODE_UUID \
--driver-info irmc_pci_physical_ids={} \
--driver-info irmc_pci_physical_ids/$PORT_UUID=LAN0-1 \
--driver-info irmc_pci_physical_ids/$VOLUME_CONNECTOR_UUID=CNA1-1
```
For iSCSI boot, volume connectors with both types iqn and ip are required. The configuration with DHCP is not supported yet.
For iSCSI, the size of the storage network is needed. This value should be specified in a node’s driver_info[irmc_storage_network_size]. It must be a positive integer < 32. For example, if the storage network is 10.2.0.0/22, use the following command:
```
baremetal node set $NODE_UUID --driver-info irmc_storage_network_size=22
```

Supported hardware¶

The driver supports the PCI controllers, Fibrechannel Cards, Converged Network Adapters supported by Fujitsu ServerView Virtual-IO Manager.

Hardware Inspection Support¶

The irmc hardware type provides the iRMC-specific hardware inspection with irmc inspect interface.

Note

SNMP requires being enabled in ServerView® iRMC S4 Web Server(Network SettingsSNMP section).

Configuration¶

The Hardware Inspection Support in the iRMC driver requires the following configuration:

It is necessary to set ironic configuration with gpu_ids and fpga_ids options in [irmc] section.

gpu_ids and fpga_ids are lists of <vendorID>/<deviceID> where:
- <vendorID>: 4 hexadecimal digits starts with ‘0x’.
- <deviceID>: 4 hexadecimal digits starts with ‘0x’.
Here are sample values for gpu_ids and fpga_ids:
```
gpu_ids = 0x1000/0x0079,0x2100/0x0080
fpga_ids = 0x1000/0x005b,0x1100/0x0180
```
The python-scciclient package requires pyghmi version >= 1.0.22 and pysnmp version >= 4.2.3. They are used by the conductor service on the conductor. The latest version of pyghmi can be downloaded from here and pysnmp can be downloaded from here.

Supported properties¶

The inspection process will discover the following properties:

memory_mb: memory size
cpu_arch: cpu architecture
local_gb: disk size

Inspection can also discover the following extra capabilities for iRMC driver:

irmc_firmware_version: iRMC firmware version
rom_firmware_version: ROM firmware version
server_model: server model
pci_gpu_devices: number of gpu devices connected to the bare metal.

Inspection can also set/unset node’s traits with the following cpu type for iRMC driver:

CUSTOM_CPU_FPGA: The bare metal contains fpga cpu type.

Note

The disk size is returned only when eLCM License for FUJITSU PRIMERGY servers is activated. If the license is not activated, then Hardware Inspection will fail to get this value.
Before inspecting, if the server is power-off, it will be turned on automatically. System will wait for a few second before start inspecting. After inspection, power status will be restored to the previous state.

The operator can specify these capabilities in compute service flavor, for example:

openstack flavor set baremetal-flavor-name --property capabilities:irmc_firmware_version="iRMC S4-8.64F"

openstack flavor set baremetal-flavor-name --property capabilities:server_model="TX2540M1F5"

openstack flavor set baremetal-flavor-name --property capabilities:pci_gpu_devices="1"

See Capabilities discovery for more details and examples.

The operator can add a trait in compute service flavor, for example:

baremetal node add trait $NODE_UUID CUSTOM_CPU_FPGA

A valid trait must be no longer than 255 characters. Standard traits are defined in the os_traits library. A custom trait must start with the prefix CUSTOM_ and use the following characters: A-Z, 0-9 and _.

RAID configuration Support¶

The irmc hardware type provides the iRMC RAID configuration with irmc raid interface.

Note

RAID implementation for irmc hardware type is based on eLCM license and SDCard. Otherwise, SP(Service Platform) in lifecycle management must be available.
RAID implementation only supported for RAIDAdapter 0 in Fujitsu Servers.

Configuration¶

The RAID configuration Support in the iRMC drivers requires the following configuration:

It is necessary to set ironic configuration into Node with JSON file option:

$ baremetal node set <node-uuid-or-name> \
  --target-raid-config <JSON file containing target RAID configuration>

Here is some sample values for JSON file:

{
    "logical_disks": [
        {
            "size_gb": 1000,
            "raid_level": "1"
    ]
}

or:

{
    "logical_disks": [
        {
            "size_gb": 1000,
            "raid_level": "1",
            "controller": "FTS RAID Ctrl SAS 6G 1GB (D3116C) (0)",
            "physical_disks": [
                "0",
                "1"
            ]
        }
    ]
}

Note

RAID 1+0 and 5+0 in iRMC driver does not support property physical_disks in target_raid_config during create raid configuration yet. See following example:

{
  "logical_disks":
    [
      {
        "size_gb": "MAX",
        "raid_level": "1+0"
      }
    ]
}

See RAID Configuration for more details and examples.

Supported properties¶

The RAID configuration using iRMC driver supports following parameters in JSON file:

size_gb: is mandatory properties in Ironic.
raid_level: is mandatory properties in Ironic. Currently, iRMC Server supports following RAID levels: 0, 1, 5, 6, 1+0 and 5+0.
controller: is name of the controller as read by the RAID interface.
physical_disks: are specific values for each raid array in LogicalDrive which operator want to set them along with raid_level.

The RAID configuration is supported as a manual cleaning step.

Note

iRMC server will power-on after create/delete raid configuration is applied, FGI (Foreground Initialize) will process raid configuration in iRMC server, thus the operation will completed upon power-on and power-off when created RAID on iRMC server.

See RAID Configuration for more details and examples.

BIOS configuration Support¶

The irmc hardware type provides the iRMC BIOS configuration with irmc bios interface.

Warning

irmc bios interface does not support factory_reset.

Starting from version 0.10.0 of python-scciclient, the BIOS setting obtained may not be the latest. If you want to get the latest BIOS setting, you need to delete the existing BIOS profile in iRMC. For example:

curl -u user:pass -H "Content-type: application/json" -X DELETE -i http://192.168.0.1/rest/v1/Oem/eLCM/ProfileManagement/BiosConfig
