ESXi host might fail with a purple diagnostic screen during VM migration from a Tintri NFSv4.1 datastore.

Products

• VMware vSphere ESXi

Issue/Introduction

When migrating virtual machines by using vSphere vMotion from a Tintri NFSv4.1 datastore, the ESXi host might unexpectedly fail with a Purple Screen of Diagnosis (PSOD).
This issue occurs due to the way Tintri NFSv4.1 servers handle NULL values in certain scenarios.

Environment

VMware vSphere ESXi 8.0
Tintri NFSv4.1 datastores

Cause

The issue is triggered by Tintri NFSv4.1 servers handling NULL values in specific conditions during VM migration.
This leads to an unexpected failure in the ESXi kernel, causing a purple diagnostic screen.

Resolution

This issue is resolved in vSphere ESXi 8.0 Update 3g.
Upgrade to this release or later to avoid ESXi host failures during VM migrations involving Tintri NFSv4.1 datastores.

Additional Information

 

• This issue is specific to Tintri NFSv4.1 datastores and does not affect other storage vendors.

• Refer to the VMware vSphere 8.0 Update 3g Release Notes for details.
