Introduction to VTMs and the VTM
The following topics introduce the Virtual Technician Module (VTM) and VTM console:
• “Overview of the VTM and VTM Console”
• “VTM System Operation and Configuration”
• “What You Can Do Using the VTM Console”
• “Parts of the VTM Console Interface”
• “Description of the VTM Console Tabs”
• “Express5800/320Ma Documentation”
Overview of the VTM and VTM Console
The Virtual Technician Module (VTM) is an adapter with firmware, which is an add-on
part of an Express5800/320Ma system. The firmware on the VTM enables authorized
system administrators to manage and diagnose the system from the local system or,
more typically, from a remote system.
Console
1-
You can use the VTM regardless of the state of the host system because the VTM runs
on standby power and has its own network connection, CPU, memory, and operating
system.
The VTM console is the Web-based interface used to monitor the Express5800/320Ma
system and to manage and diagnose system problems. The VTM console runs on a
Web browser through an HTTP server on the VTM, and provides authenticated and
secure access to the Express5800/320Ma system from any location.
System administrators typically use ftServer Management Console (ftSMC), a snap-in
to Microsoft Management Console (MMC), to manage and monitor an
Express5800/320Ma system. However, if the host system is inaccessible from ftSMC
because of network or system problems, administrators can log on to the VTM console
to troubleshoot the problem and attempt to restore the system. For more information
about ftSMC, see the online Help for ftSMC.

• “Parts of the VTM Console Interface”
VTM System Operation and Configuration
The Express5800/320Ma system provides two VTMs for redundancy in case problems
occur with one of the VTMs or I/O subsystems. One VTM is the primary, or the active
VTM. The other VTM is secondary, and operates in standby mode, monitors the
primary VTM, and takes over operation if the primary VTM becomes unavailable.
The VTM console indicates the status and state of the VTMs at the bottom left of every
Web page. The VTM console displays the status as Primary or Secondary to indicate
whether the VTM you have logged in to is the active or standby VTM. The VTM console
also displays the state as Duplexed when both VTMs are working properly, or
Simplexed if only one of the VTMs is working. If the primary VTM fails, the secondary
VTM becomes active.
Before you use the VTMs to troubleshoot a system, verify that:
• The VTMs are connected to the network or that a modem is connected to the VTM
COM port on the system.
• IP addresses are assigned to the VTMs, if your network does not use DHCP to
assign IP addresses.
• You know the user ID and password for the VTM account.
For information about connecting phone and Ethernet lines to the VTMs and
configuring the user ID, see the Express5800/320Ma ActiveService Network
Configuration Guide. For information about the user ID and password, see “Logging On
to the VTM Console” on page 2-4.

What You Can Do Using the VTM Console
What You Can Do Using the VTM Console
Use the VTM console to manage and diagnose the system in which the VTMs are
installed. You can dial in to the VTM console through a modem or, if the VTMs are
connected to a network, you can connect to the VTM over your intranet.
If you have a service contract with NEC Solutions (America), Inc. or an authorized
service representative, set up an ActiveService Network (ASN) account to enable your
system to send alerts (call-home alarm messages) to the NEC Technical Support when
unusual events occur on the system. You can also enable NEC Technical Support or
your authorized service representative to access the system through a connection to
the ASN.
Use the VTM console to troubleshoot the system by performing the following tasks:
• View the system event log to obtain state information about the host system and
the VTMs
• From the client computer running the VTM console, mount a storage device or
image on the host
• Revive the system if it is not responding
• Power on the system
• Monitor the state of the VTMs by checking the status bar
• Control the server’s keyboard, video and mouse remotely using Advanced Video
Redirection (AVR)

Status Bar
A status bar (see Figure 1-2) at the bottom of each Web page displays the following
connection information about the VTM and Express5800/320Ma system:
• VTM you are logged in to (Primary or Secondary) and whether one or both
VTMs are operating (Simplexed or Duplexed, respectively)
• Whether the server is powered on or off
• Number of users connected and ID of the users who are logged in
Figure 1-2. VTM Console Status Bar
The Manage page also displays a To Pe e r bu tt on , so that you can switch to the primary
VTM.
To Peer Button
At the time you connect to a VTM, it could be the primary or secondary VTM. You can
identify whether the VTM you are about to log on to is primary or secondary by looking
at the status bar, which displays either Primary or Secondary. For access to all the
features of the VTM console, log on to the primary VTM. The To Peer button, shown in
Figure 1-3, enables you to switch between the primary and secondary VTMs.
To switch to the other VTM, click To Peer before logging in to the VTM console.
Typically, you switch to the primary VTM so that you can use Advanced Video

Problem: LAN Settings in the Browser Are Using a Proxy Server
Symptom. A pop-up window warns: Internet Explorer could not open the
Internet site http://IP_address_of_Virtual_Technician_Module or
A connection with the server could not be established; or a page
displays the warning The page cannot be displayed.
Although other problems can cause this symptom, typically the cause is that the LAN
settings in Internet Explorer are using a proxy server.
Resolution. Specify settings to prevent Internet Explorer from using a proxy server to
connect to the VTMs.
To prevent Internet Explorer from using a proxy server to connect to the VTMs
1. On the Internet Explorer Too l s menu, click Internet Options.
2. Click the Connections tab, and then click LAN Settings.
3. If Use a proxy server is selected, do one of the following:
• If the IP addresses of the VTMs are recognized as local addresses and the
security settings on the proxy server permit, click Bypass proxy server for
local addresses. Click OK twice to close the Local Area Network (LAN)
Settings dialog box and the Internet Options dialog box.
• If the IP addresses of the VTMs are not recognized as local addresses, click
Advanced. Under Exceptions, type the IP addresses of the VTMs next to Do
not use proxy server for addresses beginning with. Click OK three times to

Reviving a System That Is Not
The “When the System Fails to Start” on page 3-1 topic describes what you can do
when a fault-resilient boot has not successfully started the operating system.
The following topics explain how to use the VTM console to revive a system when the
operating system is no longer responding:
• “When the System Is No Longer Responding”
• “Powering On the System”
• “Viewing the System Configuration”
• “Viewing the System Event Log”
• “Understanding a State-Sensitive Recovery”
• “Understanding a Fault-Resilient Boot”
When the System Fails to Start
If your system fails to start, you can perform one or both of the following procedures:
Responding
3-
• Restart a system with faulty hardware
Perform this procedure to start the system, if possible, despite a CPU enclosure or
I/O enclosure that is only partially functional.
• Restore the default BIOS setup options
Restores the system BIOS Setup options to their default (factory) settings.

When the System Is No Longer Responding
Restoring the Default BIOS Setup Options
Restore the BIOS Setup options on a system to their default (factory) settings when the
system does not start with the current settings. The default settings are optimal settings
for the system.
To restore the default BIOS Setup options
1. On the Troubleshoot Server tab, make sure that power to the system is off. Click
Power off server to turn off power to the system.
2. Click Restore default BIOS settings to select it.
3. Optionally, select Normal, the default value, or Boot with faulty hardware. See
“Restarting a System with Faulty Hardware” for more information about the Boot
with faulty hardware option.
4. Click Power on Server.
5. In the Confirmation dialog box, click Ye s.
Restarting a System with Faulty Hardware
If your system fails to start because no fully functional pair of CPU and I/O elements is
present, you can force the system to start, if possible, using a CPU element or I/O
element that is only partially functional.
To restart a system with a partially functional CPU or I/O element
1. On the Troubleshoot Server tab, make sure that power to the system is off. Click
Power off server to turn off power to the system.
2. Click Boot with faulty hardware.
3. Click Power on Server.
4. In the Confirmation dialog box, click Ye s.

When the System Is No Longer Responding
When the operating system on an Express5800/320Ma system has been operational
but ceases to respond to user actions, the system controller automatically performs a
state-sensitive recovery (SSR) to try to restore the operating system. An SSR moves
through a set of progressively more severe steps to try to restore the system. See
“Understanding a State-Sensitive Recovery” on page 3-9 for more information about
SSR.
3-2 Express5800/320Ma: Virtual Technician Module User’s Guide
If the system is still not responding after an SSR, or if the operating system has been
restored but another part of the system (for example, keyboard or mouse) is not
responding to the operating system, try the following procedures, which are listed in
order by ascending severity level:
• Perform a non-maskable interrupt from the Troubleshoot tab.
• Perform a hard reset from the Troubleshoot tab.
• Power off the system from the Manage tab.
• Force the system to power off from the Troubleshoot tab.

Performing a Non-Maskable Interrupt
If the Express5800/320Ma system is not responding, but the operating system is
running, perform a non-maskable interrupt (NMI) from the VTM console. An NMI saves
the contents of memory to a dump file, and then restarts the operating system.
Interrupts try to keep all CPUs synchronized while the system controller attempts to
resolve the problem.
When the System Is No Longer Responding
NOTE
If the operating system is not running, the NMI button is
unavailable and cannot be clicked. In this case, try
performing a hard reset.
If the NMI is successful, a message is displayed indicating that the operating system
has failed. The operating system is then restarted. If the NMI does not restore the
operating system, the system controller starts a state-sensitive system recovery, and
then starts a full fault-resilient boot if the SSR fails.
CAUTION
!
Before performing an NMI, make sure that no other
administrators are using the system.
If performing an NMI does not resolve the problem, see “When the System Is No
Longer Responding” for a list of other steps to try.
Reviving a System That Is Not Responding 3-3
When the System Is No Longer Responding
To perform a non-maskable interrupt
1. On the VTM console, click the Troubleshoot Server tab, and then click NMI.
2. On the Confirmation dialog box, click OK.

Resetting the Operating System
If the Express5800/320Ma system is not responding, and you have already performed
a non-maskable interrupt (NMI), try a hard reset from the VTM console. In this process,
the system controller does one of the following:
• If the operating system is running, the system controller performs a state-sensitive
recovery, except that it skips the NMI.
• If the operating system is not running, but standby power is available, the system
controller starts a full fault-resilient boot.
CAUTION
!
Before resetting the host system, make sure that no other
administrators are using the system.
If resetting the operating system does not resolve the problem, try powering off the
system.
To reset the operating system
1. On the VTM console, click the Troubleshoot Server tab, and then click Hard
Reset.
2. On the Confirmation dialog box, click OK.
