vserver nvme subsystem controller show

Display active NVMe controllers

Availability: This command is available to cluster and Vserver administrators at the admin privilege level.

Description

The vserver nvme subsystem controller show command displays information for established NVMe controllers. An NVMe controller is established upon each host connection to a subsystem.

Parameters

{ [-fields <fieldname>, ...]
If you specify the -fields <fieldname>, ... parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.
| [-instance ]}
If you specify the -instance parameter, the command displays detailed information about all fields.
[-vserver <Vserver Name>] - Vserver Name
Use this parameter to display the NVMe controllers that match the Vserver that you specify.
[-subsystem <text>] - Subsystem
Use this parameter to display the NVMe controllers that match the subsystem that you specify.
[-controller-id <Hex 16bit Integer>] - Controller ID
Use this parameter to display the NVMe controllers that match the controller ID that you specify. The controller ID is the identifier assigned by the NVMe subsystem upon host login and controller creation.
[-lif <text>] - Logical Interface
Use this parameter to display the NVMe controllers that match the LIF that you specify.
[-node <nodename>] - Node
Use this parameter to display the NVMe controllers that match the cluster node that you specify.
[-host-nqn <text>] - Host NQN
Use this parameter to display the NVMe controllers that match the host NQN that you specify. The host NQN is the NVMe identifier assigned to a specific host.
[-transport-protocol {fc-nvme|rdma-nvme}] - Transport Protocol
Use this parameter to display the NVMe controllers that match the transport protocol that you specify.
[-initiator-transport-address <text>] - Initiator Transport Address
Use this parameter to display the NVMe controllers that match the initiator transport address that you specify. The initiator transport address format depends on the transport protocol in use.
[-io-queue-count <integer>] - Number of I/O Queues
Use this parameter to display the NVMe controllers that match the I/O queue count that you specify.
[-io-queue-depth <integer>, ...] - I/O Queue Depths
Use this parameter to display the NVMe controllers that match the I/O queue depth that you specify.
[-admin-queue-depth <integer>] - Admin Queue Depth
Use this parameter to display the NVMe controllers that match the administrative queue depth that you specify.
