Support a new hardware type for Fujitsu PRIMEQUEST MMB

https://storyboard.openstack.org/#!/story/1726271

This spec proposes adding a new hardware type that supports deployment of servers managed by ManageMent Board(MMB) for Fujitsu PRIMEQUEST 3000 Series. MMB is a system control unit that performs management tasks, including control and monitoring in the cabinet, partition management, and system initialization.

Problem description

Since PRIMEQUEST definitely differs from iRMC interface, Ironic cannot handle Fujitsu PRIMEQUEST servers by using irmc hardware type at present. Therefore, this spec proposes a new hardware type for MMB in order to handle PRIMEQUEST by ironic. PRIMEQUEST has multiple partitions. Each partition works as a physical server. That is, a partition relates an ironic node. In addition, several partitions can be managed by one MMB. In order to control a specified partition, the ironic node has to know its partition number.

Proposed change

This spec proposes the fujitsu-mmb hardware type, implementing the Power, Management and Console. The hardware type uses ssh library in order to connect and execute commands into MMB.

Based on this premises, to be enrolled, the node MUST have the following parameters:

driver_info

  • (Required) mmb_address

    • IP address of the MMB to ssh into.

  • (Required) mmb_username

    • Username to authenticate as.

  • (Required) mmb_partition

    • Partition number to manage.

  • mmb_ssh_key_filename:

    • Filename of optional private key(s) for authentication. If mmb_ssh_password is also specified, it will be used for unlocking the private key. It recommends to store at shared volume like NFS or CIFS.

  • mmb_ssh_password

    • Password to use for authentication or for unlocking a private key. At least one of this or mmb_ssh_key_filename must be specified.

  • mmb_ssh_port

    • Port on the node to connect to. Default is 22.

We’ll define a new class:

  • fujitsu_mmb.MMBHardware

Following interfaces will be implemented:

  • MMBPower

  • MMBManagement

  • MMBConsole

MMBPower

Ironic sets/synchronizes this interfaces. After synchronization, this interface controls the power state of the nodes using MMB’s command.

MMBManagement

This interface allows the user to get and set the boot-order of a server hardware by executing the command on MMB.

MMBConsole

This interface provides serial console view by executing the command on MMB.

This hardware type will support PXEBoot for boot and ISCSIDeploy, AgentDeploy for deploy.

Security impact

This hardware type retrieves following information.

  • SSH private key filename

  • SSH password for MMB

However, ironic only stores a filename of SSH private key into driver_info as mmb_ssh_key_filename. SSH Key information doesn’t include in REST API body. Regarding SSH password, it will be hidden in REST API body like ‘*******’.
