“Deprecated VMFS volume(s) found on the host” error in ESXi hosts (2109735)

  • 110 Ratings
Language Editions


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.


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.


This issue is resolved in ESXi 6.0 Patch Release ESXi600-201608401, available at VMware Patch Downloads. For more information on downloading patch, see How to download patches in MyVMware (1021623)

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 (1003490)
Note: Restarting management agents does not impact the virtual machine power state. Also, ESXi host does not required any reboot.
