Issue/Introduction

Symptoms:
ESXi 6.0 hosts without any VMFS volumes or unmounted datastores report the warning:

Deprecated VMFS volume(s) found on the host. Please consider upgrading volume(s) to the latest version
 

Note: For additional symptoms and log entries, see the Additional Information section.


Cause

When a LUN is presented to the host for the first time, the host fails to detect the version of the file system and, therefore, is unable to compare it with the list of valid file system to return a match.

Resolution

This issue is resolved in ESXi 6.0 Patch Release ESXi600-201608401, available at Broadcom Support Portal. For more information on downloading patch, see VMware vSphere downloads, VMware Converter, OEM custom images, patches and addons in the Broadcom Support Portal

To work around this issue if you do not want to upgrade, restart the management agents on the impacted hosts. For more information, see Restarting the Management agents in ESXi
 
Note: Restarting management agents does not impact the virtual machine power state. Also, ESXi host does not required any reboot.
