Products

• VMware NSX

Issue/Introduction

• When upgrading to NSX 4.2.x from a version prior to 4.2.0 (e.g., 3.2.x, 4.1.x), the following error is observed:

         Found data inconsistencies: Found stale Entity Barrier entries

• If using SDDC Manager to perform the NSX upgrade, a similar error will be seen there:

         Check for data inconsistencies in DB: [Found data inconsistencies: Found stale Entity Barrier entries 5809]

Environment

VMware NSX 4.2.x

Cause

• NSX version 4.2.0 added a new data consistency checker framework to detect consistency-related issues in the database during an upgrade.
• These issues might cause an upgrade to fail.
• However, there is a "RESOLVE" option which remediates the issue and allows the upgrade to complete successfully.
• Note: The "RESOLVE" button automatically removes the stale entries from the database.

Resolution

• Log in to the NSX Manager UI.
• Navigate to the System > Upgrade tab.
• Locate the alarm for stale Entity Barrier entries.
• Click the RESOLVE button.
• Re-run the pre-checks to confirm the issue is cleared.
