Display active NVMe discovery controllers

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

Description

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

[-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.

[-discovery-nqn <text>] - Discovery Subsystem NQN

Use this parameter to display the NVMe controllers that match the discovery subsystem NQN that you specify.

[-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|nvme-tcp}] - 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.

[-trsvcid <text>] - Transport Service Identifier

Use this parameter to display the NVMe controllers that match the transport service identifier that you specify.

[-host-id <Hex String>] - Host Identifier

Use this parameter to display the NVMe controllers that match the host identifier that you specify. The host identifier is a 128-bit identifier assigned to a specific host.

[-admin-queue-depth <integer>] - Admin Queue Depth

Use this parameter to display the NVMe controllers that match the administrative queue depth that you specify.

[-header-digest-enabled {true|false}] - Header Digest Enabled

Use this parameter to display the NVMe controllers that have header digest enabled.

[-data-digest-enabled {true|false}] - Data Digest Enabled

Use this parameter to display the NVMe controllers that have data digest enabled.

[-kato <integer>] - Keep-Alive Timeout (msec)

Use this parameter to display the NVMe controllers that match the keep-alive timeout value (in msec) that you specify.
