Mapping an NVMe namespace to a subsystem

You must map a namespace to a subsystem when using NVMe.

Before you begin

  • You must have configured an SVM for NVMe.
  • You must have created an NVMe namespace and subsystem.

About this task

A namespace can only be mapped to a single subsystem.

  1. Obtain the NQN from the host.
  2. Add the host NQN to the subsystem: vserver nvme subsystem host add -vserver SVM_name -subsystem Subsystem_name -host-nqn Host_NQN:subsystem.Subsystem_name
  3. Map the namespace to the subsystem: vserver nvme subsystem map add -vserver SVM_name -subsystem subsystem_name -path path
  4. Verify that the namespace is mapped to the subsystem: vserver nvme namespace show -vserver SVM_name -instance
    The subsystem should be listed as the Attached subsystem.
