Bases: object

Implementation of the ‘Node’ model.

Node is the struct for a Node.

Attributes:

capacity_by_tier (list of CapacityByTier): CapacityByTier describes

the capacity of each storage tier.

chassis_info (ChassisInfo): ChassisInfo is the struct for the

Chassis.

cluster_partition_id (long|int): ClusterPartitionId is the Id of the

cluster partition to which the Node belongs.

cluster_partition_name (string): ClusterPartitionName is the name of

the cluster to which the Node belongs.

cohesity_node_serial (string): Cohesity Node Serial Number of the

Node.

disk_count (long|int): DiskCount is the number of disks in a node. disk_count_by_tier (list of CountByTier): DiskCountByTier describes

the disk number of each storage tier.

id (long|int): Id is the Id of the Node. ip (string): Ip is the IP address of the Node. is_app_node (bool): Whether node is app node. is_marked_for_removal (bool): IsMarkedForRemoval specifies whether the

node has been marked for removal.

max_physical_capacity_bytes (long|int): MaxPhysicalCapacityBytes

specifies the maximum physical capacity of the node in bytes.

node_hardware_info (NodeHardwareInfo): NodeHardwareInfo provides the

information regarding the hardware.

node_incarnation_id (long|int): NodeIncarnationId is the incarnation

id of this node. The incarnation id is changed every time the data is wiped from the node. Various services on a node is only run if incarnation id of the node matches the incarnation id of the cluster. Whenever a mismatch is detected, Nexus will stop all services and clean the data from the node. After clean operation is completed, Nexus will set the node incarnation id to cluster incarnation id and start the services.

node_software_version (string): NodeSoftwareVersion is the current

version of Cohesity software installed on a node.

node_type (string): Node type: StorageNode, AllFlashNode, RoboNode,

AppNode, etc.

offline_mount_paths_of_disks (list of string):

OfflineMountPathsOfDisks provides the corresponding mount paths for direct attached disks that are currently offline - access to these were detected to hang sometime in the past. After these disks have been fixed, their mount paths needs to be removed from the following list before these will be accessed again.

removal_reason (list of RemovalReasonNodeEnum): RemovalReason

specifies the removal reason of the node. ‘kAutoHealthCheck’ means the entity health is bad. ‘kUserGracefulRemoval’ means user initiated a graceful removal. ‘kUserAvoidAccess’ means user initiated a mark offline. ‘kUserGracefulNodeRemoval’ mean users initiated graceful node removal. ‘kUserRemoveDownNode’ mean user initiated graceful removal of down node.

removal_state (RemovalStateNodeEnum): RemovalState specifies the

removal state of the node. ‘kDontRemove’ means the state of object is functional and it is not being removed. ‘kMarkedForRemoval’ means the object is being removed. ‘kOkToRemove’ means the object has been removed on the Cohesity Cluster and if the object is physical, it can be removed from the Cohesity Cluster.

slot_number (int): Slot number occupied by this node within the

chassis.

stats (NodeStats): NodeStats provides various statistics for the

node.

system_disks (list of NodeSystemDiskInfo): SystemDisk describes the

node system disks.

classmethod from_dictionary(dictionary)

Creates an instance of this model from a dictionary

Args:

dictionary (dictionary): A dictionary representation of the object as obtained from the deserialization of the server’s response. The keys MUST match property names in the API description.

Returns:

object: An instance of this structure class.
