zh tag GPU 分区 diverges from the en slug gpu-partitioning. keep tag slugs identical across locales so tag pages and any tag matching stay aligned.
Labs 14-16 are taken by the queued SGLang, KitOps, and KAI labs, so this lab takes 17 and leaves the numbering race. Signed-off-by: Saiyam Pathak <saiyam911@gmail.com>

and secondary GPU index variables, then generate both filterdevices.index
exclusion lists from those variables. Update the mixed-profile configuration and
the Step 8 sed command to use the same variables rather than fixed index 4 or a

Parameterize the selected GPU indices.
Line 76 tells readers to adapt the exclusion lists. Line 414 still selects GPU index 4. Line 579 only matches the original exclusion list.
If a reader selects different compatible GPUs, the mixed-profile test pins an unregistered GPU. The Step 8 sed command then leaves the values unchanged, so the fifth Pod cannot spill to the second GPU.
Define primary and secondary GPU index variables. Generate both exclusion lists from those variables. Do not use fixed index values or a literal list replacement.

Scope device-plugin operations to $NODE.
The chart schedules hami-device-plugin on every node labeled gpu: on. NODE only constrains the workload and node checks. .items[0] can select another device-plugin Pod, while kubectl rollout restart daemonset/hami-device-plugin restarts the plugin on every matching GPU node. Require a single-node cluster or provide target-node-only device-plugin operations for these steps.

What type of PR is this?
/kind documentation
What this PR does / why we need it:
Adds an advanced hands-on Dynamic MIG lab based on the verified RTX PRO 6000 run from August 11, 2026.
The lab builds HAMi commit
634bf2b32e68after #2378 and covers:operatingmodeversusmigStrategy;1g.24gballocation and four-placement saturation;1g.24gband2g.48gbplacement;It includes reusable values, manifests, a mixed-profile helper, sidebar wiring, and a Chinese translation-pending page. All commands and outputs come from the original hardware run.
This uses Lab 14 because open PR #782 currently proposes Lab 13. The number can be adjusted before merge if needed.
Testing:
The full build passes for English and Chinese.
npm teststill has the existing markdown-negotiation module-format failure, unrelated to this lab.AI assistance disclosure:
AI assistance was used to adapt the verified article into the repository lab format. I reviewed the commands, outputs, safety warnings, manifests, and final rendered build.
Related documentation update: #794
The same RTX lifecycle was revalidated on August 19 through Project-HAMi/HAMi#2725; all scenarios passed and the node was restored successfully.
