Are you licensed for vMotion?

Is vMotion enabled on the vSwitches on both ESXi servers?

When ransomware hits your clients, what do you do?

MSPs: Endpoint security isn’t enough to prevent ransomware.
As the impact and severity of crypto ransomware attacks has grown, Webroot fought back, not just by building a next-gen endpoint solution capable of preventing ransomware attacks but also by being a thought leader.

This issue occurs if jumbo frames (MTU : 9000) is enabled for the vMotion vmkernel port group, but is not enabled on the physical switch.

What was the MTU set to, and does your physical switches support Jumbo Frames, because its recommended.

awesome !

1. use webclient
2. test ping from one ESXi host to VMK on another ESXI
3. change the port group MTU on the VMKernal interface to 1500
