Issue/Introduction

Symptoms:
  • vCenter Server upgrade fails with the error:

    Error
    Internal error occurs during execution of upgrade process.

    Resolution
    Send upgrade log files to VMware technical support team for further assistance.
     
  • In the /var/log/vmware/upgrade/bootstrap.log file on the destination vCenter Server Appliance, there are entries similar to:

  • On the source vCenter Server Appliance running the command ifconfig does not return information for eth0.
  • On the source vCenter Server Appliance running the command less /etc/udev/rules.d/70-persistent-net.rules returns similar to:
# PCI device 0x15ad:0x07b0 (vmxnet3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:c2:d0:31", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x15ad:0x07b0 (vmxnet3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:ae:44:97", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
 
 


Environment

VMware vCenter Server Appliance 6.5.x

Cause

This issue occurs when the eth0 network adapter is not found on the source vCenter Server Appliance. There are multiple reasons why the eth0 adapter name could have changed:
  • If the adapter was removed and added to the source vCenter Appliance it will create eth1 instead of replacing eth0.
  • MAC address changes will cause the adapter to be renamed.
  • In some cases, if the vCenter Server appliance was restored from backup the adapter name will change.
  • The vCenter Server Appliance was cloned.

Resolution

To resolve the Internal error occurs during execution of upgrade process issue, use one of these options:

Option 1: Remove the invalid entries from the 70-persistent-net.rules file

  1. Connect the source vCenter Server Appliance with root credentials.
  2. Run this command to enable access the Bash shell:

    shell.set --enabled true
     
  3. Type shell and press Enter.
  4. Edit the /etc/udev/rules.d/70-persistent-net.rules with this command:

    vi /etc/udev/rules.d/70-persistent-net.rules
     
  5. Using the entries in the symptoms section edit the 70-persistent-net.rules file changing the MAC address for eth0 to the entry for eth1:

    For example, the current entry is:

    # PCI device 0x15ad:0x07b0 (vmxnet3)
    #SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:c2:d0:31", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

    Edit this to look similar to:

    # PCI device 0x15ad:0x07b0 (vmxnet3)
    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:ae:44:97", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
     
  6. Restart the vCenter Server Appliance.

Option 2: Rename 70-persistent-net.rules file

  1. Connect the source vCenter Server Appliance with root credentials.
  2. Run this command to enable access the Bash shell:

    shell.set --enabled true
     
  3. Type shell and press Enter.
  4. Rename the 70-persistent-net.rules to 70-persistent-net.rules.old with this command:

    mv /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/70-persistent-net.rules.old
     
  5. Restart the vCenter Server Appliance.
  6. Verify the /etc/udev/rules.d/70-persistent-net.rules file has been updated with the correct MAC address for eth0.

Option 3: Change the ifcfg-eth0 file to configure the current IP address

  1. Open the /etc/sysconfig/network/ifcfg-eth0 file using a text editor.
  2. Change the required fields such as IP address, subnet mask.
  3. Restart the network service by running this command.

    /etc/init.d/network restart
     
  4. Run ifconfig to confirm both the network adapter has the configured settings.
