description	Bring up NVIDIA HGX/DGX datacenter GPU hosts on Ubuntu 24.04 LTS — air-gapped or connected, Secure Boot enabled. Covers B300/B200/H100/A100/L40S/L4 driver+fabricmanager+NVLSM+DOCA-OFED install order and exact package set from NVIDIA CUDA repo + DOCA repo. Triggers on B300/B200/HGX/DGX install, "fabricmanager won't start", "system not yet initialized" / cudaErrorSystemNotReady, NVLSM missing, ib_umad not loading, DOCA-OFED before NVIDIA driver, nvidia-driver-pinning-XXX, nvlink5-XXX, nvidia-open vs cuda-drivers, "Blackwell requires open kernel modules", ConnectX-7/8 bridge device, FM exact-version-match, gpu-operator cuda-validator CrashLoopBackOff, B300 PCI ID 0x3182, air-gap CUDA + DOCA mirror, three-tier DOCA GPG key, MOK enrollment, DKMS sign, Dell PowerEdge XE9780/XE9785 baseboard firmware v1.4.30, iDRAC Redfish virtual AC cycle DellOemChassis.ExtendedReset, generic "install nvidia driver ubuntu 24.04 datacenter".
when_to_use	Use for bringing up an NVIDIA datacenter GPU host (HGX, DGX, or inference-card servers) on Ubuntu 24.04 LTS. Covers the full air-gapped path from clean OS install to the gpu-operator cuda-validator pod passing. Trigger when fabricmanager fails to start, nvidia-smi sees no GPUs on B200/B300, the cuda-validator loops with "system not yet initialized", a host needs coherent DOCA-OFED + NVLSM + NVIDIA driver install, MOK enrollment for Secure Boot is needed, or a Dell XE9780/XE9785 chassis needs baseboard firmware updated.

nvidia-datacenter-bringup

Opinionated greenfield recipe for NVIDIA datacenter GPUs on Ubuntu 24.04 LTS — get from a clean OS install to a healthy host where nvidia-smi reports all GPUs, nvidia-fabricmanager is active (running), and the gpu-operator cuda-validator pod passes. Air-gap is the primary case; connected sites use the same packages from the same upstream URLs.

Decision tree

Question	Answer	Read
Has Blackwell silicon (B300/B200/B100)?	Yes	Open kernel modules mandatory — proprietary is unsupported [[open-modules-transition]]
Grace Hopper (GH200)?	Yes	Open kernel modules mandatory (same as Blackwell). Otherwise 8-GPU SXM path [[hopper-recipe]]
HGX 8-GPU SXM with 3rd-gen NVSwitch (H100/H200/H800 in XE9680 or similar)?	Yes	Open recommended (not mandatory). Use cuda-drivers-fabricmanager-<branch> meta; skip nvlink5-<branch>, NVLSM, DOCA-OFED entirely. Min driver 525+ for H100, 535+ for H200 [[hopper-recipe]]
HGX 4-GPU SXM (H100 in XE8640, A100 4-GPU)?	Yes	No NVSwitch on this baseboard — direct NVLink mesh between 4 GPUs. Skip fabricmanager entirely + DOCA + NVLSM. Three-package install: driver + container-toolkit [[hopper-recipe]]
HGX A100 8-GPU (2nd-gen NVSwitch)?	Yes	Same as 8-GPU SXM H100 path. Min driver 450.xx. ALI not available — FM trains NVLinks at boot
L40S, L40, L4, H200 NVL, or other PCIe-only?	Yes	Driver + container-toolkit only. Skip DOCA-OFED, fabricmanager, NVLSM entirely. Validation reduces to nvidia-smi clean — no fabric registration to check
4th-gen NVSwitch (B200/B300/B100)?	Yes	Must install nvlink5-<branch> meta (or nvlsm + libnvsdm + libibumad3 + infiniband-diags separately). FM talks to switches via CX7 bridge — DOCA-OFED is non-optional [[fabric-manager-guide]] §"Additional Steps for B200/B300"
Dell XE9780 or XE9785 chassis?	Yes	Step 0 is firmware ≥ v1.4.30. Use Redfish DellOemChassis.ExtendedReset, NOT BIOS Full Power Cycle [[dell-firmware]]
Dell XE9680 / XE9640 / XE8640?	Yes	Enable iDRAC Direct USB Port in BIOS before GPU baseboard FW updates (KB 000308105). Same DellOemChassis.ExtendedReset activation pattern [[dell-firmware]]
Secure Boot enabled?	Yes	Enroll one DKMS MOK — signs both NVIDIA and DOCA-OFED modules [[secure-boot]]
Air-gapped?	Yes	Mirror three repos. Total budget ~3 GB. Three-tier GPG keys for DOCA [[airgap-mirror]]
gpu-operator on top?	Yes	Pre-installed driver mode: driver.enabled=false, toolkit.enabled=false. Know about B300 issue #2231 [[gpu-operator]]

The 10-step install order

Order matters: DOCA before driver, MOK before any DKMS build, firmware before everything.

0. Dell baseboard firmware ≥ v1.4.30 + Redfish virtual AC cycle      [[dell-firmware]]
1. OS prep: kernel headers, blacklist nouveau                         [[recipe]]
2. Secure Boot: generate + import MOK (once, signs both stacks)       [[secure-boot]]
3. Add repos: NVIDIA CUDA + DOCA (+ Ubuntu archive subset)            [[airgap-mirror]]
4. Install DOCA — modules-load.d generated, ib_umad autoloads         [[recipe]]
5. Pin NVIDIA driver branch: apt install nvidia-driver-pinning-580    [[packages]]
6. Install driver: apt install nvidia-open-580 (open is mandatory)    [[packages]]
7. Install fabric stack: apt install nvlink5-580                      [[packages]]
8. Install nvidia-container-toolkit (lives in same CUDA repo)         [[packages]]
9. Validate: nvidia-smi clean, FM active, ib_umad loaded, Fabric Completed/Success

nvlink5-580 is the compute-only fabric meta — pulls nvidia-fabricmanager + nvlsm + libnvsdm + libnvidia-nscq + nvidia-imex + collectx-bringup + mft{,-oem,-autocomplete} + nvidia-dkms-580-open + libnvidia-compute-580 (and transitively libibumad3 + infiniband-diags). It does NOT pull nvidia-utils-580 / nvidia-smi — that's why step 6 installs nvidia-open-580 (full userland) AS WELL. Dependency tree verified live from the NVIDIA CUDA repo for Ubuntu 24.04 amd64 — see [[packages]].

Pitfalls catalogue

The mistakes that cost hours, ordered by frequency in the wild:

1. Proprietary modules on Blackwell. nvidia-driver-580-server (no -open) installs cleanly but the kernel module silently doesn't bind to B300 silicon. nvidia-smi reports no GPUs. NVIDIA's open-modules transition blog: proprietary is unsupported on Blackwell and Grace Hopper. Cure: use nvidia-open-<branch> from the CUDA repo. See [[open-modules-transition]].

2. DOCA installed AFTER the driver. ib_umad does not autoload at boot; nvidia-fabricmanager.service fails. NVIDIA forum 353369. Cure: install DOCA first. If already broken, reinstall DOCA OR echo ib_umad | sudo tee /etc/modules-load.d/ib_umad.conf && sudo modprobe ib_umad && sudo systemctl restart nvidia-fabricmanager. See [[troubleshooting]].

3. Dell BIOS Full Power Cycle. The iDRAC web-UI "Full Power Cycle" and the standard Redfish Chassis.Reset FullPowerCycle do not reliably activate the GPU baseboard subcomponents (HMC, NVSwitch, CX bridge firmware). Symptom: firmware update "succeeded" but old version still reports. Cure: Dell-specific DellOemChassis.ExtendedReset. See [[dell-firmware]].

4. Mixing Ubuntu archive nvidia-driver-XXX-server with CUDA-repo nvlsm. Ubuntu archive's FM version lags NVIDIA's by patches; NVLSM is only in CUDA repo. Rip out Ubuntu archive NVIDIA packages and go single-source CUDA repo. See [[packages]].

5. MOK enrolled for NVIDIA but not for DOCA-OFED (or vice versa). Both stacks are DKMS-built. One /var/lib/dkms/mok.pub signs both — enroll once, covers everything. There is no Canonical-signed precompiled HWE module for ConnectX, so MOK is unavoidable on B300 + Secure Boot. See [[secure-boot]].

6. cudaErrorSystemNotReady blamed on driver. This is the textbook FM-not-running signature on any NVSwitch system. The fix is always: confirm nvidia-fabricmanager.service is active (running) and its version matches the loaded driver. See [[troubleshooting]] and [[gpu-operator]].

7. gpu-operator B300 PCI ID warning loop (#2231). Cosmetic, not fatal. nvidia-operator-validator logs unable to get device name: failed to find device with id '3182'. Open in upstream since 2026-03-18; NVIDIA acknowledged "B300 should be supported" but waiting on must-gather. Symptom is benign — pods still work. See [[gpu-operator]].

8. Driver 570.158.01 + operator-managed driver mode. FM start script broken (gpu-operator #1595). Cure: pin ≥570.172.08 OR move to 580+. Or just use pre-installed-driver mode and let the host's systemd unit own FM. See [[gpu-operator]].

Validation

After step 9 these should all be true. Expected output on a healthy 8-GPU B300:

$ nvidia-smi --query-gpu=name,driver_version --format=csv,noheader
NVIDIA B300 SXM6 270GB, 580.126.20
NVIDIA B300 SXM6 270GB, 580.126.20
# ... 8 identical lines

$ systemctl is-active nvidia-persistenced nvidia-fabricmanager nvidia-nvlsm
active
active
active

$ lsmod | grep -E '^nvidia|^nvidia_uvm|^nvidia_peermem|^ib_umad' | awk '{print $1}'
nvidia_peermem
nvidia_uvm
nvidia
ib_umad

$ nvidia-smi -q -i 0 | grep -A 2 Fabric
        Fabric
            State                  : Completed
            Status                 : Success

$ nvidia-smi nvlink --status -i 0 | head -3
GPU 0: NVIDIA B300 SXM6 270GB (UUID: ...)
         Link 0: 200 GB/s
         Link 1: 200 GB/s

If any value is missing or wrong (e.g. State: Not Initialized, lsmod missing ib_umad, systemctl is-active reports inactive), see [[troubleshooting]] keyed by the symptom.

On a fresh 8-GPU B300, FM takes ~30–90 s to finish fabric registration on first boot. The gpu-operator validator pod may CrashLoopBackoff transiently during this window — only sustained crashes >3 min are real failures.

Hard out-of-scope

• Windows, workstation/Optimus, non-Ubuntu (RHEL/SLES handled by NVIDIA's own guides)
• vGPU / MIG runtime config (separate concern from bring-up)
• DGX OS (NVIDIA's preinstalled bundle — different workflow, see DGX OS docs)
• gpu-operator helm-values for full cluster config (host-side stops at validator passing)
• Multi-node NVLink Switch (NVL72-style); single-chassis NVL8 only
• Data-plane CX-8 NIC config (bridge role only — those are the management PFs)
• Vendor firmware for non-Dell chassis (Supermicro/HPE/Lenovo — defer to vendor docs)
