Cannot ping Console Domain or access the Web Console
Use this procedure to determine if the state of the Console Domain virtual machine is the reason why you are unable to access the System Platform Web Console.
Troubleshooting steps
About this task
The Web Console runs on the Console Domain virtual machine, so if output of the xm list command described in this procedure shows that the Console Domain virtual machine is in either a normal or abnormal shutdown state, then the administrator is likely to lose access to the Web Console.
Important If you encounter these symptoms after completing the following procedure, contact Avaya Support at http://support.avaya.com. Take no further action to troubleshoot the issue locally.
Procedure
- Log in to the System Domain (Domain-0) as admin.
- Enter su - to log in as root.
- At the prompt, type xm list.
The xm list command shows information about the running virtual machines in a Linux screen.
You should see two virtual machines running at this time: System Domain (shown as Domain-0) and Console Domain (shown as udom in xm list).
A state of r indicates that the virtual machine is running. A state of b indicates that the virtual machine blocked.
Note The blocked state does not mean that there is a problem with the virtual machine. It only means that the virtual machine is currently not using any CPU time.
Other possible virtual machine states are:
p: paused
s: shutdown
c: crashed
For more information on the information displayed, see the Linux manual page for the xm command.
- On the Linux screen, type exit to log off as root. Type exit again to log off from System Domain (Domain-0).

If High Availability Failover is enabled, the output of the xm list command differs for the active server and the standby server. The output for the active server is similar to that shown above.

If High Availability Failover is enabled, the output for the standby is similar to the following:
