DGX Station MIG

Treat inspection and planning as read-only. Treat every apply as disruptive.

Workflow

1. Run scripts/dgx-assist system inspect --json.
2. Search the playbooks for the user's MIG concern and cite relevant results.
3. Read compatibility.capabilities.mig_inspection. If it is false, stop and explain that the detected release has no MIG inspection profile.
4. Run mig inspect and mig profiles. Use only profiles reported by the installed driver. This read-only step is available on the recognized Software 1.0 and Software 2.0 profiles.
5. Before planning, require compatibility.capabilities.mig_mutation to be true. If it is false, report the observed state but do not suggest a layout or work around the restriction.
6. Require the desired exact layout. Do not choose a layout from model names or nominal memory sums.
7. Run mig plan --layout "<layout>".
8. Present current and proposed state, exact commands, active clients, privilege, workload impact, reset/reboot possibility, and restoration commands.
9. If any client is active, stop. Tell the user dgx-assist will not terminate it.
10. Obtain explicit confirmation immediately before mutation.
11. Run mig apply --plan-id "<id>" --yes.
12. Report every verified MIG UUID. On partial failure, stop and present only the recorded restoration plan.

Safety requirements

• Never use a hardcoded GPU index, profile table, or assumed placement.
• Never destroy instances, reset a GPU, reboot, or change MIG mode outside an approved plan.
• Never kill a GPU process or take over a service.
• Invalidate the plan when clients, mode, profiles, release, driver, or instances change.
• Do not improvise further mutations after partial failure.
• Do not treat Fabric Manager as a normal Station prerequisite.
• Treat --yes only as approval already obtained.

Read references/workflow.md before planning or applying a layout.
