Guides administrators through diagnosing and resolving common issues that occur during system upgrade and downgrade procedures, including cluster convergence verification and log analysis.
Best practice: general failure considerations for ACI switch upgrades
Outlines key troubleshooting steps and operational considerations to ensure system stability when addressing ACI switch upgrade failures.
Common reasons for download failure
Lists common reasons that can cause download failures and provides guidance for resolution.
Cluster convergence verification
Lists the steps and indicators for verifying APIC controller cluster convergence through the GUI interface.
Controller upgrade pause verification
Provides methods to verify that the controller upgrade or downgrade has paused using either the GUI or the REST API.
Verify whether a controller upgrade or downgrade scheduler paused using the GUI
Verify the status of a controller firmware upgrade or downgrade scheduler to determine if it has paused due to issues.
REST API verification for controller upgrade or downgrade scheduler pause status
Provides the API endpoint and response format to verify whether a controller upgrade or downgrade scheduler is paused.
Switch upgrade or downgrade pause verification
Provides methods to verify that the switches upgrade or downgrade paused using either the GUI or the REST API.
Verify whether a switch upgrade scheduler paused using the GUI
Verify whether a switch upgrade scheduler has paused and resume the upgrade process if needed.
REST API switch upgrade scheduler pause verification
Provides the API method to verify whether a switch upgrade scheduler is paused in a maintenance policy.
Resuming paused schedulers for controller maintenance policies
Describes how to resume paused schedulers for controller maintenance policies using either GUI or REST API.
Resume paused controller upgrade scheduler using the GUI
Configure the controller upgrade scheduler to resume operations when it has been paused.
Use the REST API to resume paused controller upgrade scheduler
Configure the REST API to resume a paused scheduler for a controller maintenance policy.
Resume paused switch upgrade scheduler using the GUI
Configure the switch upgrade scheduler to resume after it has been paused in a maintenance group.
Resume paused switch upgrade scheduler using the REST API
Configure the REST API to resume a paused switch upgrade scheduler for a maintenance policy.
APIC installer log files
Lists the APIC upgrade logs location and file structure for monitoring upgrade progress.
ACI switch installer log files
Lists the location and viewing methods for ACI switch installer log files.
Best practice for collecting tech-support files
Consider using the On-Demand TechSupport feature as the preferred method for collecting tech-support files, with local collection as an alternative when cluster health is degraded.
