Creating a namespace for an NVMe device

Use stand-alone diagnostics to create a namespace for an NVMe device.

Before you begin

For system and stand-alone diagnostic requirements, see Secure data deletion for devices by using stand-alone diagnostics.

Procedure

  1. If you have already booted the system from stand-alone diagnostics and entered the terminal type, go to step 8.
  2. Power off the system. For instructions, see Stopping a system.
  3. Boot the system from stand-alone diagnostics. For information about running stand-alone diagnostics, see Running the stand-alone hardware diagnostics.
  4. From the Welcome to AIX screen, type 1 to select the terminal that you are using as the system console.
  5. From the Diagnostics Operating Instructions menu, press Enter to continue.
  6. From the Function Selection menu, type 3 to select Task Selection.
  7. From the Define Terminal menu, enter a terminal type.
    Note: If you are using a remote terminal connection such as PuTTY, use either the VT320 or VT340 terminal emulation.
  8. From the Task Selection List, select the NVMe Manager option.
  9. From the NVMe Manager screen, select the Namespace Management and Attachment option.
  10. From the Namespace Management and Attachment screen, select the Create a Namespace option.
  11. From the Namespace Create Supported Controllers window, select the device for which you want to create a namespace.
    Note: If the device for which you want to create a namespace is not displayed, the maximum number of namespaces might already be created and you cannot create any more namespaces.
  12. From the Create a Namespace screen, enter the desired namespace size. If you do not know what to enter for the LBA Format and Attach after Create fields, use the default values.
  13. From the COMMAND STATUS screen, press F3 (function key 3) to return to the Namespace Management and Attachment screen.
  14. To create more namespaces, repeat steps 10 through 13. To create the maximum number of namespaces, repeat steps 10 through 13 until you cannot create anymore namespaces in step 11.
