To avoid configuration failure of VMs deployed by using a VM template converted or cloned from a VM, restart the VM after upgrading its CAStools.
On the top navigation bar, click VMs. If multiple clusters exist in the system, you must also select a cluster from the left navigation pane.
Select a VM, click More on the VM tile, and then select Mount CAStools, or select a VM from the navigation pane to enter the VM overview page, click More Actions, and then select Mount CAStools.
In the dialog box that opens, click OK.
