System Components

InfiniSDK allows inspecting the hardware components in the system, and obtaining various attributes about them.

Nodes

system.components.nodes is a collection of infinisdk.infinibox.components.Node objects:

>>> print('System has {0} nodes'.format(len(system.components.nodes)))
System has 3 nodes

Drives

InfiniSDK provides several ways of querying the system’s drive information, system.components.enclosures and system.components.drives. The first is intended for traversing the actual topology of the system through the Enclosure component, while the second is an aggregate of all drives in the system (Drive objects):

>>> for enclosure in system.components.enclosures:
...     for drive in enclosure.get_drives():
...         pass # <- do something with drive here

>>> for drive in system.components.drives:
...     pass # <- do something with drive here

You can also query drives by their attributes, for instance by state:

>>> from infinisdk import Q
>>> for drive in system.components.drives.find(Q.state != 'ACTIVE'):
...     print('Drive', drive, 'is not in ACTIVE!!!')

FC Ports

For each Node, you can use the Node.get_fc_ports() method to obtain the FC ports it contains. Each FC port is returned as a Python dictionary containing its attributes

>>> for node in system.components.nodes:
...     for fc_port in node.get_fc_ports():
...         if not fc_port.is_link_up():
...             print('Port', fc_port.get_field('wwpn'), 'of', node, 'is down!')

Services

Use Node.get_service() to get a service by its name:

>>> node.get_service('mgmt')
<Service id=system:0_rack:1_node:3_service:mgmt>

Or get a specific service type (core/mgmt):

>>> s = node.get_management_service()
>>> s = node.get_core_service()
