Solution

VUM is downgrading my VIB package

The VC does not have the correct VSM software bundle ID.

If the VSM and VC bundle IDs do not match, VUM installs the VIB corresponding to the older VSM version on the host.

Upgrade the VSM bundle ID on the VC.

1. "Verifying Bundle IDs" procedure

2. Upgrading the VSMs procedure in the following document:

Cisco Nexus 1000V Virtual Ethernet Module Software Installation Guide, Release 4.0(4)SV1(3).

Unable to add the host to VSM

The VEM is not installed on the host

Verify that VEM sofware is installed and running on the host. If not, install VEM software.

1. "Verifying that the correct VEM Software Version is Installed" procedure

2. "Verifying that the VEM is Running on the Host" procedure

3. If not installed, install VEM.

For more information, see the Cisco Nexus 1000V Virtual Ethernet Module Software Installation Guide, Release 4.0(4)SV1(3).

4. "Verifying that the correct VEM Software Version is Installed" procedure

Unable to add a host

The host is part of another DVS.

Verify whether the host is part of another DVS. If so, then remove it and add it to the correct DVS.

1. "Verifying the VMware NICs on a DVS" procedure

2. Remove the host from the DVS where it is currently installed.

3. Add the host to the correct DVS.

For more information, see the Cisco Nexus 1000V Virtual Ethernet Module Software Installation Guide, Release 4.0(4)SV1(3)

The upgrade fails

VMware patch level is 219382 or higher.

If so, you cannot install VEM using VUM.

Verify the patch level. If required, upgrade the VUM and install VEM software.

1. "Verifying that the correct VEM Software Version is Installed" procedure

2. Do one of the following:

Upgrade your VUM to the latest version.

Install the VEM software.

For more information, see the Cisco Nexus 1000V Virtual Ethernet Module Software Installation Guide, Release 4.0(4)SV1(3).

The upgrade commands were not used in the correct sequence, causing a mismatch between the bundle ID on the VSM and VC.

If the VSM and VC bundle IDs do not match, VUM installs the VIB corresponding to the older VSM version on the host.

The following is the correct sequence for entering upgrade commands:

1. vmware vem upgrade notify

2. vmware vem upgrade proceed

3. vmware vem upgrade complete

Identify the problem host and repeat the upgrade.

1. "Verifying Upgrade Status" procedure

2. Identify which host failed to upgrade.

3. Verify that the VUM repository has the VIB that must be installed on that host.

Your vCenter VUM build is older than Update 1, and your proxy is enabled.

Disable the proxy on the VUM and retry the upgrade.

Upgrade your VC to Update 1 and VUM to VMware vCenter Update Manager 4.0 Update 1 Patch 1.


Verifying Bundle IDs

Use the following command to verify that the software bundle IDs on the VSM and VC match.

show vmware vem upgrade status
Example:
switch # show vmware vem upgrade status
Upgrade VIBs: System VEM Image
Upgrade Status: 
Upgrade Notification Sent Time: 
Upgrade Status Time(vCenter): 
Upgrade Start Time: 
Upgrade End Time(vCenter): 
Upgrade Error: 
Upgrade Bundle ID:
VSM: VEM400-201003101-BG
DVS: VEM400-200912267-BG

Verifying that the correct VEM Software Version is Installed

Use the following command to verify that the correct VEM software version is installed.

vemcmd show version

Example:
# vemcmd show version
VEM Version: 4.2.1.1.0.1.0-1.9.7
VSM Version: 4.2(1)SV1(1) [build 4.2(1)SV1(0.1)]
System Version: VMware ESXi 4.0.0 Releasebuild-208167

Verifying that the VEM is Running on the Host

Use the following command to verify that the VEM is running on the host.

vem status

Example:
~ # vem status
VEM modules are loaded 
Switch Name Num Ports Used Ports Configured Ports MTU Uplinks 
vSwitch0 64 3 64 1500 vmnic0 
DVS Name Num Ports Used Ports Configured Ports Uplinks 
n1000v 256 9 256 vmnic1 VEM Agent is running

Verifying the VMware NICs on a DVS

Use the following command to verify the VMware NICs associated with a DVS.

esxcfg-vswitch -1

Example:
~ # esxcfg-vswitch -l
Switch Name      Num Ports   Used Ports  Configured Ports  MTU     Uplinks 
vSwitch0         128         3           128               1500    vmnic0

  VM Network            0        0           vmnic0 
  Management Network    0        1           vmnic0 
DVS Name         Num Ports   Used Ports  Configured Ports  MTU     Uplinks 
bldvs3           256         52          256               1500    vmnic2,vmnic1
  DVPort ID           In Use      Client 
  352                 1           vmnic1
