Alert Definition Symptom Recommendations
The fault tolerance state of the virtual
machine has changed to "Needs
Secondary" state.
VM Fault Tolerance state changed to
needs secondary (Fault symptom).
Keep HA enabled when Fault
tolerance (FT) is required to protect
virtual machines.
vSphere HA cannot perform a failover
operation for the virtual machine
vSphere HA virtual machine failover
unsuccessful (Fault symptom)
1 If the error information reports
that a le is locked, the virtual
machine might be powered on a
host that the vSphere HAmaster
agent can no longer monitor by
using the management network or
heartbeat datastores.
2 The virtual machine might have
been powered on by a user on a
host outside of the cluster. If any
hosts are declared oine,
determine whether a networking
or storage problem caused the
situation.
3 If the error information reports
that the virtual machine is in an
invalid state, an in-progress
operation might be preventing
access to the virtual machine les.
Determine whether any operations
are in progress, such as a clone
operation that is taking a long time
to complete.
4 You can also try to power on the
virtual machine and investigate
any returned errors.
Virtual machine is experiencing
memory compression, ballooning or
swapping due to memory limit.

Recommended virtual machine
memory size
Increase the memory limit for the
virtual machine to match the
recommended memory size.
Alternatively, remove memory limit
for the virtual machine.
