NAME

ocf_heartbeat_nvmet-port - NVMe-oF target export agent

SYNOPSIS

DESCRIPTION

Manages NVMe-oF ports. An NVMe-oF port is part of an NVMe-oF target. A port must be created after the subsystem. It exposes one or multiple subsystem(s) including the enclosed namespace(s) to the network.

SUPPORTED PARAMETERS

port_id

The NVMe port number is a 16 bit number.

(unique, optional, integer, default 0)

type

The NVMe transport type. Should be one of 'tcp', 'rdma', 'fc' or 'loop'.

(optional, string, default "tcp")

addr_fam

The address family of the address. Should be 'ipv4', 'ipv6' or 'fc'.

(optional, string, default "ipv4")

svcid

The transport service identifier. The TCP/IP port number this target binds to, or its RDMA protocol equivalent.

(optional, integer, default 4420)

addr

The transport address. The TCP/IP address this targets binds to, or its RDMA protocol equivalent.

(required, string, no default)

nqns

A space-separated list of NQNs that should be exported through this NVMe-oF-Target port. This list needs to have at least one entry.

(required, string, no default)

SUPPORTED ACTIONS

This resource agent supports the following actions (operations):

start

Starts the resource. Suggested minimum timeout: 10s.

stop

Stops the resource. Suggested minimum timeout: 10s.

status

Performs a status check. Suggested minimum timeout: 10s. Suggested interval: 10s.

monitor

Performs a detailed status check. Suggested minimum timeout: 10s. Suggested interval: 10s.

meta-data

Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.

validate-all

Performs a validation of the resource configuration. Suggested minimum timeout: 10s.
