task 4 updated

4. Verify the BlueField-3 host and DPU setup

I checked the lab repository first, then verified the live Dell host (dh5) and the BlueField-3. I did not flash a BF-Bundle. Recaptured 2026-10-01. Setup is verified. NVIDIA’s doca_dma_copy sample was built on the DPU, not run. That extra copy test is not required to close this task.

OOB SSH host key for 172.22.222.3 changed (ED25519 SHA256:XTzDfcnjS/3Md+81CuFC5rRJdFKimaWwp8xJWBklooE). After ssh-keygen -R 172.22.222.3 the login is the same DPU: bf-bundle-3.5.0-89_26.07_ubuntu-24.04_64k_prod.

Which DOCA-Host and BF-Bundle versions belong together

NVIDIA ships both packages per release. Install DOCA on the host before BF-Bundle on the card. This host has doca-all, so host vs BF-Bundle is Level 2.

Pair	Policy
Live: DOCA-Host 3.5.0098 + BF-Bundle 3.5.0-89	Yes. Matched 3.5 / 26.07
Old: DOCA-Host 3.4 + DPU 2.6	No. No longer installed
Lab BF2 file bf-bundle-2.7.0-33_…	No. Wrong generation and card

doca_dma_copy

Not part of the written task title. I compiled the sample on the DPU (meson setup + ninja under /tmp/doca-apps-build). doca_dma_copy -h works (DOCA 3.5.0098). -p / -r / -f are the run flags. I did not start the two-sided copy.

Host meson of the full apps tree failed earlier on missing json-c until libjson-c-dev is installed. I did not need a host binary to close Task 4.

Status

Task 4 is done. Host DOCA 3.5.0098, DPU bf-bundle-3.5.0-89_26.07_ubuntu-24.04_64k_prod, bfver, PCIe / mst, OOB and rshim login are verified. Live pair is in policy. doca_dma_copy was built on the DPU .
