Troubleshooting Cisco Data Center Infrastructure (DCIT) — Question 51

An engineer upgrades Cisco UCS firmware from release 3.1(2) to release 3.1(3) using AutoInstall. Both fabric interconnects go offline during the software upgrade installation and issue multiple FSM retries in the DeployPollActivate stage. Which set of actions resolves the issue?

Answer options

• A. Clear the startup version of the default infrastructure and server pack. Remove the service pack from the subordinate node. Upgrade with the Force attribute through AutoInstall.
• B. Enable the management interface monitoring policy on the fabric interconnects. Initiate a configuration backup on both fabric interconnects. Commit the pending fabric interconnect reboot activity.
• C. Fix the rights to 666 with the debug plugin on the primary fabric interconnect. Save the current configuration on the running fabric interconnect. Continue the upgrade on both fabric interconnects.
• D. Acknowledge the error and reboot the primary fabric interconnect. Clear the default firmware version and upload a new one. Restart the upgrade process manually.

Correct answer: A

Explanation

Option A is correct because it addresses the issues causing the fabric interconnects to go offline during the upgrade by clearing the startup version and using the Force attribute for the upgrade. The other options do not resolve the underlying issue of the failed upgrade process and may lead to further complications or do not provide a definitive solution to the problem at hand.
