Having the following notification after adding a new VMFS volume to your VMware vSphere/vCenter 6?
Deprecated VMFS volume(s) found on the host. Please consider upgrading volume(s) to the latest version.
If this message show up even though they are at the latest version, it mean you have hit a known issue of vCenter 6 (which is still pending to be fixed in future patch release).
To get rid of this message, just restart the Management Agents on your ESXi hosts. Follow this procedure to proceed :
1. Enable SSH on the affected host(s) :
Configuration > Security Profile > Services > Properties…
2. Login to your host using your favourite SSH client.
3. Issue the following commands :
/etc/init.d/hostd restart /etc/init.d/vpxa restart
The output will look like this :
[root@hv01:~] /etc/init.d/hostd restart watchdog-hostd: Terminating watchdog process with PID 34317 hostd stopped. Ramdisk 'hostd' with estimated size of 1053MB already exists hostd started. [root@hv01:~] /etc/init.d/vpxa restart watchdog-vpxa: Terminating watchdog process with PID 34934 vpxa stopped. [root@hv01:~]
The message should be gone now.
NOTE : It is normal for the host to vanish/disconnect from vCenter during this operation, this will also trigger an alarm. This won’t be service impacting for the guests VMs.
