Assigning Members
VMs, ports and LAGs may be added to the distributed VM group only after the
VM profile is assigned. Group members are added, pre ‐ provisioned or removed
from distributed VM groups in the same manner as with local VM groups ( “Local
VM Groups” on page 280 ), with the following exceptions:
 VMs: VMs and other VEs are not required to be local. Any VE known by the
virtualization management server can be part of a distributed VM group.
 The VM group
vlan
option (see page 280 ) cannot be used with distributed VM
groups. For distributed VM groups, the VLAN is assigned in the VM profile.
Synchronizing the Configuration
When the configuration for a distributed VM group is modified, the switch
updates the assigned virtualization management server. The management server
then distributes changes to the appropriate hypervisors.
For VM membership changes, hypervisors modify their internal virtual switch
port groups, adding or removing internal port memberships to enforce the
boundaries defined by the distributed VM groups. Virtual switch port groups
created in this fashion can be identified in the virtual management server by the
name of the VM profile, formatted as follows:
Lenovo_
<VM profile name>
(or)
Lenovo_
<VM profile name>
_
<index number> (for vDS profiles)
Using the VM Group command path
(
CN 4093(config)# virt vmgroup
<x>
vm
) to add a server host interface to
a distributed VM group does not create a new port group on the virtual switch or
move the host. Instead, because the host interface already has its own virtual
switch port group on the hypervisor, the VM profile settings are applied to its
existing port group.
Note:
When applying the distributed VM group configuration, the virtualization
management server and associated hypervisors must take appropriate actions. If a
hypervisor is unable to make requested changes, an error message will be
displayed on the switch. Be sure to evaluate all error message and take the
appropriate actions to be sure the expected changes are properly applied.
Removing Member VEs
Removing a VE from a distributed VM group on the switch will have the following
effects on the hypervisor:
 The VE will be moved to the
Lenovo_Default
(to the
Lenovo_Default_
<index number> in case of vDS
)
port group in VLAN 0
(zero).
 Traffic shaping will be disabled for the VE.
 All other properties will be reset to default values inherited from the virtual
switch.
