netapp_eseries.host.ipoib

Configures OpenSM subnet manager.

Example Playbook

  • hosts: eseries_host_group collections:
    • netapp_eseries.host tasks:
    • name: Ensure Expected InfiniBand subnet managers are configured. import_role: name: ib_opensm

Example Inventory File

ansible_host: 192.168.1.100 ansible_ssh_user: ssh_username ansible_become_password: ssh_password eseries_ib_opensm_subnet_manager_configure: true

General Notes

- All InfiniBand networks requires at least one subnet manager to be running, even if there are now switches and your E-Series storage system is directly connected to the host.
- In order to control multiple subnets on SLES and Ubuntu hosts, we've created a opensm.service and placed it in /etc/systemd/system/; this has the effect of overriding the default opensm.service service file.
- When eseries_ib_opensm_subnet_manager_configure == True then all known InfiniBand interface ports will be configured even if one is not specified in eseries_ib_opensm_interfaces list.
- A configuration file will be created for each subnet manager so the default opensm.conf file will never be used. Instead, opensm.conf.[0-9]* will be generated for each subnet manager in the default opensm path for your Linux operating system.

Variables

eseries_ib_opensm_subnet_manager_configure: # Default for whether to configure OpenSM (Default: false). eseries_ib_opensm_subnet_prefix_base: # Default OpenSM subnet manager's subnet prefix base. The last two digits will be determined by device port ordering (Default: "0xfe800000000000"). eseries_ib_opensm_subnet_priority: # Default OpenSM subnet manager's priority. eseries_ib_iser_opensm_subnet_priority can be used instead (Default: 0). Choices: 0-15 (15 is highest priority). eseries_ib_opensm_options: # Key-value pairs for all interfaces' opensm.conf files (example: {"virt_enabled": "2"}). eseries_ib_opensm_interfaces: # List of InfiniBand interfaces.

  • name: # (Required) Use the name of InfiniBand interface (i.e. ib0, ib1) when IPoIB has been configured, otherwise use _ (i.e. mlx5_0_1, mlx5_0_2) configure: # Whether to configure OpenSM for port (Default: True). subnet_prefix: # OpenSM subnet manager's subnet prefix. priority: # OpenSM subnet manager's priority. options: # Key-value pairs for the interface's opensm.conf file (example: {"virt_enabled": "2"}). eseries_ib_opensm_ubuntu_packages: # Default package list for ubuntu (Default: opensm). eseries_ib_opensm_suse_packages: # Default package list for ubuntu (Default: opensm). eseries_ib_opensm_rhel_packages: # Default package list for ubuntu (Default: opensm). eseries_ib_opensm_kernel_modules: # Default loaded kernel modules (Default: [rdma_cm, mlx5_core, ib_ipoib]). eseries_ib_opensm_log_path: /var/log/ # Default log path. Individual logs will be produced for each interface defined (opensm.conf.X.log); otherwise, # all logging will be issued to opensm.log. eseries_ib_opensm_uninstall: # Whether to uninstall the ib_opensm role. (Default: false)
