Courts InfiniBand inventory was updated with new switches and HCAs. What should operators validate in UFM?
Select an answer to reveal the explanation.
Short Explanation
New gear that UFM can’t see might as well be invisible. After courts update InfiniBand inventory, confirm UFM covers every switch and HCA on the list.
Full Explanation
After Courts InfiniBand inventory is updated with new switches and HCAs, operators should validate that UFM monitoring coverage includes the full updated municipal inventory. Discovery and coverage checks confirm every new switch and host channel adapter is visible, managed, and eligible for link and health monitoring. Without that validation, new fabric elements can carry production RDMA traffic while remaining invisible to the InfiniBand management plane.
Assuming UFM subnet manager routing weights were optimized for the new switches and HCAs fails because optimizing routing weights is a traffic-engineering task, not a coverage-validation step; it does not confirm that every new Courts switch and HCA is visible and managed in UFM. Assuming UFM event notification policies were tuned for court workload alert thresholds fails because tuning alert thresholds addresses notification behavior, not inventory completeness; it does not verify that new switches and HCAs are discovered and covered by UFM monitoring. Quarantining unknown fabric devices in the inventory database pending manual root-cause analysis fails as the validation step here because it treats expected inventory growth as a security incident instead of confirming UFM discovery and monitoring coverage for switches and HCAs that were legitimately added to the Courts fabric.
Exam caveat: Coverage validation is about monitoring completeness, not automatically approving every discovered GUID. Reconcile UFM discovery against the authorized Courts inventory list; investigate mismatches instead of blindly accepting or quarantining them. Operational check: After inventory change, refresh or verify UFM discovery, compare discovered switches and HCAs to the updated Courts asset list, confirm monitoring policies apply to new devices, and generate a coverage report showing 100 percent of authorized InfiniBand inventory is managed before declaring the change complete.
