This example shows allocated namespace identifiers selected:

hbacmd nvme-list-ns 10:00:00:90:fa:5d:05:a9 50:06:01:60:90:20:5C:38 nqn.2014-

08.com.example:nvme.host.sys.xyz 1

Information similar to the following is displayed:

Allocated Namespaces:

Namespace ID : 0x00000003

Namepsece ID : 0x00000004

4.2.2.8 The nvme-id-ns Command

The nvme-id-ns command sends the NVMe identify command for a namespace and displays the results. In addition,

if namespace management is supported, the command can retrieve capabilities that are common across all namespaces.

Syntax

hbacmd nvme-id-ns <WWPN> <Target WWPN> <NQN> <NSID> <Type> [CtrlID=<ctrlid>] [raw]

Parameters

NOTE: If the raw parameter is not specified, the output displays only a few namespace attributes, in human-readable

format. If the raw parameter is specified, the entire data structure is displayed in hexadecimal format.

Support Requirements

 Mandatory for nvme-id-ns WWPN TWWPN NQN NSID 0 [CtrlID=<ctrlid>] (identify active namespace)

 Optional for nvme-id-ns WWPN TWWPN NQN NSID 1 [CtrlID=<ctrlid>] (identify allocated namespace)

Examples

This example identifies active namepaces:

hbacmd nvme-id-ns 10:00:00:90:fa:5d:05:a9 50:06:01:60:90:20:5C:38 nqn.2014-

08.com.example:nvme.host.sys.xyz 0x00000001 0

Information similar to the following is displayed:

Attributes for Namespace 0x00000001:

IEEE Extended Unique Identifier : 00-00-00-00-00-00-00-00

Size : 32768 (Logical Blocks)

Capacity : 32768 (Logical Blocks)

Usage : 32768 (Logical Blocks)

WWPN The WWPN of the FC initiator port.

Target WWPN The WWPN of an FC port on an NVMe-capable device.

NQN The qualified name of the NVMe subsystem.

NSID The namespace identifier, in hexadecimal; use it to list only controllers attached to the specified namespace. Set to

0xFFFFFFFF to retrieve capabilities that are common across all namespaces.

Type The namespace identifier type:

0 = Active

1 = Allocated

Must be set to 0 if NDSID=0xFFFFFFFF.

ctrlid The controller that processes the request, in hexadecimal.

raw Specifies that the output is to be provided in hexadecimal format (optional).
