Problem
The VSM to VEM migration fails in
Layer 2 / Layer 3 mode installation.
• The installer application finishes
successfully with port migration in
Layer 3 mode.
The VEM is added to the vCenter
•
but does not display when the show
module command is entered on the
VSM.
After loading the previously saved
configuration file, the installation
application does not complete.
Recommended Action
Check if there is any VM running on the
•
vSwitch. You need to power off all VMs
running on the vSwitch before migration.
Check if the vCenter is Virtual Update Manager
•
(VUM) enabled. Before migration, the host is
added to the DVS by using VUM.
• Verify that the native VLAN in the upstream
switch configuration is correct.
• Ensure that the VUM repositories are
up-to-date and accurate.
• Verify that the Layer 3 control profile VLAN is
configured as a system VLAN.
• Verify that the uplink profile is allowing the
Layer 3 control VTEP VLAN and that it is a
system VLAN.
From the ESX host (VEM), enter a vmkping to
•
the mgmt0/control0 IP address. It should be
successful. If not, check the intermediate
switches for proper routes between the subnets.
The VTEP should be pingable from the VSM.
•
Check the vCenter MOB for opaque data
•
propagation.
Check the configuration file for appropriate
•
contents.
You might need to change a few of the fields
Note
before reusing the previously saved files.
Check if a VM with the same name already
•
exists in the DC.
This can be identified by reviewing the Virtual
Machine field in the configuration file.
