nvme_subsystem_map

An NVMe subsystem map is an association of an NVMe namespace with an NVMe subsystem. When an NVMe namespace is mapped to an NVMe subsystem, the NVMe subsystem's hosts are granted access to the NVMe namespace. The relationship between an NVMe subsystem and an NVMe namespace is one subsystem to many namespaces.

Name Type Description

anagrpid

string

The Asymmetric Namespace Access Group ID (ANAGRPID) of the NVMe namespace.

The format for an ANAGRPID is 8 hexadecimal digits (zero-filled) followed by a lower case "h".

There is an added computational cost to retrieving this property's value. It is not populated for either a collection GET or an instance GET unless it is explicitly requested using the fields query parameter. See Requesting specific fields to learn more.

namespace
