Not Protected. The Secondary VM is not running. Possible reasons are
listed in the table.
Table 27‑1. Reasons for Primary VM Not Protected Status
Reason for Not Protected Status Description
Starting Fault Tolerance is in the process of
starting the Secondary VM. This
message is only visible for a short
period of time.
Need Secondary VM The Primary VM is running without a
Secondary VM, so the Primary VM is
currently not protected. This occurs
when no compatible host in the cluster
is available for the Secondary VM.
Correct this by bringing a compatible
host online. If a compatible host is
online in the cluster, you might need
to investigate further. Under certain
circumstances, disabling Fault
Tolerance and then re-enabling it
corrects this problem.
Disabled Fault Tolerance is currently disabled
(no Secondary VM is running). This
happens when Fault Tolerance is
disabled by the user or when vCenter
Server disables Fault Tolerance after
being unable to power on the
Secondary VM.
VM not Running Fault Tolerance is enabled but the
virtual machine is powered off. Power
on the virtual machine to reach
Protected state.
Secondary location
Displays the ESXi host on which the Secondary VM is hosted.
Total Secondary CPU
The CPU usage of the Secondary VM, displayed in MHz.
Total Secondary
Memory
The memory usage of the Secondary VM, displayed in MB.
vLockstep Interval
The time interval (displayed in seconds) needed for the Secondary VM to
match the current execution state of the Primary VM. Typically, this interval
is less than one-half of one second. No state is lost during a failover,
regardless of the vLockstep Interval value.
Log Bandwidth
The amount of network capacity being used for sending vSphere Fault
Tolerance log information from the host running the Primary VM to the host
running the Secondary VM.
For each host configured to support Fault Tolerance, you can view information about its fault tolerant
virtual machines by accessing the host's Summary tab in the vSphere Client. The Fault Tolerance section of
this screen displays the total number of Primary and Secondary VMs residing on the host and the number of
those virtual machines that are powered on. If the host is ESX/ESXi 4.1 or greater, this section also displays
the Fault Tolerance version the host is running. Otherwise, it lists the host build number. For two hosts to be
compatible they must have matching FT version numbers or matching host build numbers.
