Upgrade Blocked by Precheck Error Without Suppression Warning Option

Products

• VMware Avi Load Balancer

Issue/Introduction

• The upgrade process from version 31.x to a higher release may get stuck due to a precheck error such as a missing backup requirement or another issue without displaying the “Suppress Warning” option in the UI.

 

• Ideally, the UI should display the “Suppress Warning” option immediately after the precheck error appears.

Environment

• Avi Load Balancer
• Affected Versions: 31.1.x,31.2.x

Cause

The “Suppress Warning” option is intentionally not available after a page refresh, as the UI provides only a limited time window to act in order to prevent later pre-check inconsistencies.

Resolution

• Once the upgrade is initiated from the UI, the page must not be refreshed during the pre-check process, as doing so will interrupt the operation.
• Opening the upgrade page in a duplicate tab also triggers a refresh, causing the upgrade progress status to disappear.
• To ensure the option appears, keep the original page open without performing any refresh until the pre-check process completes, only then “Suppress Warning” button be visible under the Recent Actions section.
• A note or warning message will be added in future releases advising users not to refresh the page while the precheck is in progress.
