Error "Network setting (IPV4/IPV6) Invalid" when upgrading InterScan Messaging Security Virtual Appliance (IMSVA)

• No MAC address is defined in ifcfg-eth0.
• HWADDR was removed after copying the VM to another location.
• IMSVA network does not start properly.

1. SSH to IMSVA with root account.
2. Confirm the MAC address of the port eth0 with command "#ifconfig". The result of this command should give you a line similar to the following:

   eth0 Link encap:Ethernet HWaddr [MAC Address]

3. Copy the value of HWaddr, which is the MAC address of eth0.
4. Backup /etc/sysconfig/network-scripts/ifcfg-eth0 and then open it with vi command:

   #cp /etc/sysconfig/network-scripts/ifcfg-eth0 ifcfg-eth0.bak
   #vi /etc/sysconfig/network-scripts/ifcfg-eth0

   Then add the following line. (Use MAC address from the previous step.)

5. Save the file.
6. Restart network service:

   #service network restart

7. Proceed to upgrade by following page 5-17 to 5-20 of the IMSVA 9.0 Installation Guide.
    

   Especially, pay attention to the following statement:

   Do not restart IMSVA services until all devices have been upgraded.
   Do not run /mnt/backup/dry_run.sh or /mnt/backup/confirm.sh on any of the parent or child device before you finish upgrading all the devices.

In case other errors occur, take screenshots and collect /var/app_data/installlog.
