Constants

 
NVME_IDENTIFY_CNS_SPECIFIC_NAMESPACE
Information for a specific namespace will be returned.

The Identify Namespace NVME_IDENTIFY_NAMESPACE_DATA structure is returned to the host for the namespace specified in the Namespace Identifier (NSID) member of the NVME_COMMAND structure, if the namespace is attached to this controller.

If the specified namespace is an inactive namespace ID, then the controller returns a zero filled data structure.

If the controller supports Namespace Management and NSID is set to FFFFFFFFh, the controller returns an NVME_IDENTIFY_NAMESPACE_DATA that specifies capabilities that are common across namespaces.
NVME_IDENTIFY_CNS_CONTROLLER
Information for a controller will be returned to the host in an Identify Controller NVME_IDENTIFY_CONTROLLER_DATA data structure.
NVME_IDENTIFY_CNS_ACTIVE_NAMESPACES
A list of active namespaces will be returned.

A list of up to 1024 active namespace IDs is returned to the host containing active namespaces with a namespace identifier greater than the value specified in the NSID member of the NVME_COMMAND structure.
NVME_IDENTIFY_CNS_DESCRIPTOR_NAMESPACE
Information for a descriptor namespace will be returned.
NVME_IDENTIFY_CNS_NVM_SET
An NVM_SET_LIST will be returned.
