NAME

nvme-list-ns − Send NVMe Identify List Namespaces, return result and structure

SYNOPSIS

nvme list−ns <device> [−−namespace−id=<nsid> | −n <nsid>]
[−−csi=<command_set_identifier> | −y <command_set_identifier>]
[−−all | −a] [−−output−format=<fmt> | −o <fmt>]

DESCRIPTION

For the NVMe device given, sends an identify command for namespace list and provides the result and returned structure.

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1). If the starting namespace in the list always begins with 0 unless the '−−namespace−id' option is given to override.

On success, the namespace array is printed for each index and nsid for a valid nsid.

OPTIONS

−n <nsid>, −−namespace−id=<nsid>

Retrieve the identify list structure starting with the given nsid.

−y <command_set_identifier>, −−csi=<command_set_identifier>

If this value is given, retrieve the identify list structure associated with the specified I/O command set.

−a, −−all

Retrieve the identify list structure for all namespaces in the subsystem, whether attached or inactive.

−o <format>, −−output−format=<format>

Set the reporting format to normal, or json. Only one output format can be used at a time.

EXAMPLES

• Print the namespaces present for zoned command set in JSON format

# nvme list−ns /dev/nvme0 −y 2 −a −o json

• Print the namespaces present for NVM Command Set in normal format

# nvme list−ns /dev/nvme0
