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

This example identifies allocated namespaces:
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 1
Information similar to the following is displayed:
Attributes for Namespace 0x00000001:
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).
