Introduction

This documentation describes how to use the hardware of VENICE, the
Media Production Hub manufactured by Rohde & Schwarz DVS GmbH
(in short ’DVS’).

VENICE is a highly flexible server system for the capturing and playout
of audio and video content. Especially designed for highly optimized,
file-based broadcast workflows, it provides multiple independent chan­nels and supports natively the most common compressed formats.
With VENICE you can easily capture live content, e.g. from cameras di­rectly, and access data for playout operations – if required both at the
same time and in the format that suits your workflow best. During each
operation you can control an externally connected device via RS-422 to
act as a player or recorder, either in a manual or automatic (autoedit)
operation mode.

The VENICE hardware uses Linux as its operating system and will be
equipped with a storage capacity of several terabytes. It stores the cap­tured material in a selectable file format (compressed or uncompres­sed) directly on the connected storage.

With its flexible software the VENICE server can be controlled either lo­cally or from remote client stations in the network. With this you can
place the hardware of VENICE at any location you like and still have full
control over it.

The VENICE system can be delivered in two hardware variants, de­pending on the type of use or the performance that is required. The
VENICE 4U system will be delivered with two system/metadata hard
disks and 14 main storage hard disks. The VENICE HPE system will be
delivered with two system/metadata hard disks and 16 main storage
hard disks. Both systems come in a slim 4U chassis.

panel connectors and the power supply.

2.3.1 The Rear of the System

This section provides an overview of the rear of the system:

Overview

main connector panel The main connector panel provides most of

the standard in- and outputs of VENICE to give
you the full functionality of the system. It
holds, for example, the connectors for remote
control and video I/Os. It is in more detail de­scribed in section “Main Connector Panel” on
page 2-13.

ATX connector panel On this panel you can find the standard con-

nectors of the computer system. Further infor­mation about them can be found in section
“ATX Connector Panel” on page 2-16.

tem with power. It consists of several indepen­dent power supply units: Even if one fails the
others will still supply enough power to keep
the system operational. Further information
about the power supply can be found in sec­tion “Power Supply” on page 2-20.

2.3.2 Digital Video I/Os

This section contains some information about the digital video in- and
outputs of VENICE.

The full complement of four video channels is optionally avail­able. In its standard variant VENICE will be delivered with two
video channels.

VENICE HPE will be delivered with only two video channels as
standard.

DVS usually names the input/output connectors/ports of the digital vid­eo signals alphabetically: the main video stream is then available, for in­stance, on port A and the secondary video stream on port B. Individual
video channels on the other hand are labeled with numbers.

For YUV you normally require one link (connectors named ’A’, single
link). For YUVA you will need two links (’A’ for YUV and ’B’ for the key
signal). With RGB you will always need two links (’A’ and ’B’, dual link).

Because VENICE provides up to four independent video channels (dif­ferent video rasters and color modes), up to four SDI input ports and
four SDI output ports are available. With this YUV can be transmitted
by all channels independently by default. By changing the speed of the
ports to 3-Gbit/s SDI, independent dual-link connections can be real­ized. They provide all the features of a standard dual-link connection,
but require only one connector instead of two.

2-12

Video channel 1 and, if available, video channel 3 can also be switched
to a standard dual-link connection. Then, the second video channels of
the video channel pairs 1/2 and 3/4 (i.e. channels 2 and 4) will not be
available and their SDI ports have to be used for the secondary video
signal (link B).

The following tables show the signal distribution over the I/O ports for
the different video rasters (color modes) when either SDTV or a

1.5-Gbit/s connection are configured for the channels, or the channels
are set to 3 Gbit/s:

You can select the HDMI port(s) of VENICE by setting the output prior­ity in the software to ’DVI’ and then selecting the raster.

The first and, if available, the third HDMI port of VENICE (i.e. channels 1
and 3 named port(s) HDMI A of the slot panel connectors) are
HDMI 1.4 a, providing all outputs up to 2K. When using a 2K raster on
these ports, the second video channels of the video channel pairs 1/2
and 3/4 (i.e. channels 2 and 4 named port(s) HDMI C of the slot panel
connectors) will not be available. The ports HDMI B and HDMI D of the
slot panel connectors provide no function.

2.3.6 Power Supply

The redundant power supply provides the system with power. It con­sists of several independent power supply units: Even if one fails the
others will still offer enough power to keep the system working.

The system can be operated with one power supply unit out
of order. However, if another one fails, a continued operation
of the system cannot be guaranteed. Therefore, it is recom­mended to change a failed power supply unit immediately
(see section “Power Supply Maintenance” on page 5-14).

The state of the power supply units can be easily checked ei­ther with their LEDs as explained below or with the general
alarm LED (see section “Operation Items” on page 2-4).

The following provides an overview of one of the power supply units:

2.4 Battery Backup Unit

To prevent data loss especially for the me­tadata, the system/metadata hard disks
(see section “Introduction to RAID” on
page 5-2) are protected by a battery back­up unit. If the system’s operation gets in­terrupted, for example, in case of a power
failure, it will provide power to the cache
of the connected RAID controller, so that
buffered data will not get lost. Once the
operation of the system is restored, the
cached data will be written to the hard
disks.

The battery backup unit is located inside the casing of the DVS system,
fastened to an air duct:

4.2 Shutting Down the System

There are several possibilities to shut down the DVS system. All depend
on whether the operating system is already loaded, frozen or not com­pletely loaded. Please act accordingly.

To shut down the system perform the following according to the state
of the system’s operating system:

After a shut-down wait at least ten seconds before starting the
system again. This time is needed to safely erase all memory
banks of the system.

With the operating system fully loaded

If the operating system is up and running, there are two ways to shut
down your system:

1. Turn the system off by shutting down the operating system the

usual way.
The operating system will then save your personal settings and once it
has ended, the system will turn off.

2. Alternatively, you can initiate a fast shut down by pressing the

power switch briefly.

The fast shut down may not save all your system data and
personal settings before the system turns off.

Some settings will be saved and afterwards the system turns off.

With the operating system frozen or not completely loaded

If the operating system is not responding anymore or not completely
loaded, perform the following:

This procedure can cause corrupted system data. However, the
system should be sufficiently protected against this by the
journaling file system and the battery backup unit (see section
“Battery Backup Unit” on page 2-21).

 Shut down the system by pressing the power switch until the sys-

tem turns off.

The system will then shut down immediately.

5.1 Hard Disk Maintenance

This section deals with the possible event of a hard disk failure. First,
some introductory information about RAID are provided. After that fol­low descriptions how to act when a hard disk fails.

5.1.1 Introduction to RAID

In a system where huge amounts of data are processed, large storage
capacities combined with high data throughputs are mandatory. To
provide both at the same time it is common practice in the area of video
and digital film to configure several hard disks together into a stripe set
or RAID. The IT world has defined several ’levels’ of RAID, most of them
providing some kind of data protection.

The RAID feature makes the DVS system tolerant of disk failures. Even
with a broken disk operations can still be continued and, once the failed
disk has been replaced, the missing data can be recovered easily. The
data protection is provided by a RAID controller installed inside the sys­tem which independently administers the data protection for the sets
of hard disks connected to it. The system/metadata hard disks of the
VENICE system for example, are protected by RAID 1, meaning by a
mirroring of the data between two disks. If one of the hard disks fails,
the missing data can be restored with the mirrored information stored
on the other disk.

The main storage consists of several hard disks that are protected by a
RAID level that ensures best performance and protection. With this, the
data can be e.g. striped across hard disks during write procedures. At
the same time the information necessary to rebuild a failed hard disk
(parity information) is generated and written across the disks as well.
RAID protection ensures that one or more disks of a disk set can fail
and your data will still be recoverable due to the information stored on
the other disks. Different RAID levels mean a different number of max­imum disk fails and differences in storage capacity. Especially server
systems make use of higher RAID levels because, particularly with larg­er disk capacities, the recovery of a single disk can take a long time and
the failure of a second disk in the meantime is not unlikely anymore.
The following table details the differences between the two variants
VENICE 4U and VENICE HPE:

With the available RAID feature the DVS system can withstand disk fail­ures without losing data or access to data.

The following figures show a representation of the hard disk arrays of
the DVS systems (see also section “Hard Disk Array” on page 2-8).
They indicate the locations of the disk sets (RAID packs) in the hard disk
arrays:

The system/metadata hard disks of the VENICE HPE are in­stalled inside the system in disk carriers.

5.1.2 Identifying a Broken Hard Disk

In case of an alarm or when suspecting a worn hard disk, you have to
identify the broken hard disk first in order to replace it.

An alarm can be caused by a number of reasons. Please refer
to section “Troubleshooting” on page A-2 first for further de­tails about what to do in case of an alarm.

If a hard disk fails, the alarm will be sounded by a RAID con­troller. It cannot be switched mute with the mute button of the
operation items. It can be turned off either with the RAID soft­ware manager or by replacing the broken hard disk.

In some cases you will see further, e.g. visible signs in the
event of a hard disk failure which are described below.

Data accesses to the hard disk array are still possible because
any missing data will be recalculated from the parity informa­tion stored on the other hard disk(s). This can limit the overall
performance and real-time operations may no longer be possi­ble.

Contrary to the VENICE 4U system, on the VENICE HPE no
other e.g. visible signs will be shown in case of the failure of a
system/metadata hard disk. It is recommended to configure an
E-Mail notification to get informed when a system/metadata
hard disk fails.

In case of a storage hard disk failure in the VENICE HPE you
will see other, e.g. visible signs as described in this subsection.

5-4

The information about how to replace a hard disk in section
“Replacing a Hard Disk” on page 5-5 are valid only for the hard
disks of the main storage of the VENICE HPE variant. For the
VENICE 4U the information still apply to all hard disks.

Maintenance

Replace the failed disk as soon as possible. If you do not re­place a broken disk in time and another disk fails in the mean­time, your data may be unrecoverable.

Before replacing a hard disk you have to gather the log files of
the RAID controller. If you know how to do this, you may pro­ceed on your own. If not, please contact the DVS service de­partment first.

In most cases you can find the broken disk by simply observing the
LEDs of the disk array (see section “Hard Disk Array” on page 2-8).
While performing continuous accesses to the data, it will be the one:

– no longer blinking (either continuously on or off),
– irregularly blinking compared to the other hard disks of the

same disk set, or

– showing a hard disk or disk carrier related error (see section

“Hard Disk Array” on page 2-8).

Once the broken disk has been identified, you can replace it as de­scribed in section “Replacing a Hard Disk” on page 5-5.

1

Replacing the wrong hard disk, i.e. a good one instead of the
broken one, may result in a total loss of data.

If you are unsure about having detected the correct hard disk,
please contact the DVS service department.

5.1.3 Replacing a Hard Disk

As soon as the broken hard disk has been identified (see section “Iden­tifying a Broken Hard Disk” on page 5-4), it can be replaced easily. The
replacement of a broken hard disk can be divided into three steps:

1. Removing the hard disk from the system.

2. Replacing the hard disk.

3. Reassembling it into the system.

All steps are explained in the following.

Before replacing a hard disk you have to gather the log files of
the RAID controller. If you know how to do this, you may pro­ceed on your own. If not, please contact the DVS service de­partment first.

Step 1: Removing the Hard Disk

The hard disks that are accessible at the front of the system are con­nected to the system with the help of disk carriers. They can be re­moved easily, even when the system is running (hot-swappable).

For an overview of a disk carrier as well as further information
about it see section “Hard Disk Array” on page 2-8.

The system/metadata hard disks of the VENICE HPE are in­stalled inside the system in disk carriers. In case of a failure
please contact the DVS service department.

To remove a hard disk from the system perform the following:

 If appropriate, stop all accesses to the hard disk array of your sys-

tem, for example, by exiting the video system software and sever­ing the network connections.

 Lift the faceplate of the system (see section “Faceplate” on

page 2-7).

 Then, unlatch the disk carrier of the defective hard disk by pressing

the opener of the disk carrier (1).

This will cause the lever to come out of the disk carrier so that it pro­trudes from the rest of the disk carriers.

 Take the lever and turn it in its hinge (2) until it cannot be moved

further:

Figure 5-3: Pulling out the lever

This takes the hard disk installed in the disk carrier out of the system’s
interfaces inside.

 Once the interface connections inside the system are severed, you

can pull the disk carrier out of the system.

Now the hard disk is removed from the system and it has to be replaced
in the next step.

Maintenance

Step 2: Replacing the Hard Disk

To replace the hard disk do the following:

Significant environmental changes, for example, altitude,
voltage, temperature, shock, vibration, etc., can damage a
hard disk. Therefore, handle hard disks with great care.

 Unscrew the screws that fix the hard disk to the disk carrier.

 Exchange the broken disk with a new one and assemble it in the

disk carrier with the screws.

It is best to use the same brand and type of hard disk again.
Otherwise a loss of performance might occur.

After that the hard disk is replaced and the disk carrier with the new
disk has to be reassembled in the system.

Step 3: Reassembling the Hard Disk

After replacing the hard disk, the disk carrier with the new disk has to
be reassembled in the system. For this perform the following:

 Slide the disk carrier back into its shaft at the disk array.

1

2

 Push the disk carrier completely back into the shaft by applying

pressure to the disk carrier directly (i.e. do not use the lever to push
the carrier). Move it until you feel the resistance of the hard disk
interface inside the system and until the lever retracts by itself from
the pushing.

It is important that you do not use the lever to insert the
disk carrier. Apply an even pressure only to the carrier di­rectly until the lever moves back by itself.

 Then simply close the lever until it snaps back in place which as a

result will slide the carrier completely back in.

The disk carrier of the replaced disk should be level with the
others of the array.

Once the faceplate of the DVS system is back in place, the replacement
of the hard di sk is finish ed . After several minutes the replaced hard disk
will be automatically recognized by the system. Then the rebuild of the
data will be initiated on its own. When the system has finished the re­build, the DVS system will be fully operational again.

During a rebuild real-time processes may not be possible. It is
recommended to restrict accesses to the hard disk array until
the rebuild is finished.

A rebuild takes several hours. It is strongly recommended to
avoid accesses to the disk array during this time, otherwise it
may take considerably longer.

5.2 Opening and Closing the Casing

Some tasks described in this manual require an opening of the sys­tem’s casing and the closing of it afterwards once the intended work is
finished. Both tasks will be explained in this section.

5.2.1 Opening the Casing

To open the casing of the DVS system perform the following:

The system you are working on operates with voltages
that can be hazardous to your health. Never work on the
system or access its interior with the power cable(s) being
plugged in. Make sure the power supply is disconnected
from the components you intend to work on.

The system must be operated only with the chassis’ cover in­stalled to ensure proper cooling.

 Shut down the system as described in section “Shutting Down the

System” on page 4-2.

 Disconnect all power cords from the system.

 Press the two buttons at the top of the system (1) and move the

cover towards the rear of the system (2).

Once the cover is slid backward, it can be taken off the system.

5.2.2 Closing the Casing

After finishing your task at hand you have to close the casing of the
DVS system again. For this perform the following:

 Simply put the cover back on and slide it into place until it locks.

 Afterwards reconnect the power cords.

5-8

With this the task of closing the casing is finished and you can turn the
system back on at any time.

5.3 Fan Maintenance

To cool the many hard disks installed in the system as well as the other
electronic parts (e.g. the motherboard), the system is equipped with
several fans that can be exchanged in case of a failure easily. This sec­tion describes what to do if a fan failure takes place.

When a fan failure occurs, you will be notified by a lit alarm LED and
the sounding of an alarm buzzer of the system. The alarm can be
switched mute with the mute button at the front of the system (see sec­tion “Operation Items” on page 2-4). Then you have to do the following
to exchange the failed fan:

Maintenance

An alarm can be caused by a number of reasons. Please refer
to section “Troubleshooting” on page A-2 first for further de­tails about what to do in case of an alarm.

The system you are working on operates with voltages
that can be hazardous to your health. Never work on the
system or access its interior with the power cable(s) being
plugged in. Make sure the power supply is disconnected
from the components you intend to work on.

Maintenance inside the system should only be performed
by personnel qualified for handling and testing electrical
equipment.

Computer hardware contains components that are sensitive
to electrostatic discharge. If you touch them without precau­tionary measures, they can be destroyed. Use a wrist strap
connected to ground when accessing electronic parts and
take care of grounding the system. Avoid touching the inter­nal components of the computer system.

 Open the casing of the system as described in section “Opening the

Casing” on page 5-8.

 Unscrew the finger protection grille from the broken fan and after-

wards screw off the fan from the fan bracket.

 Replace the broken fan with a new one and reassemble the fan

module: Screw the fan to the fan bracket and afterwards the finger
protection grille to the fan.

Only use original manufacturer spare parts. Other spare
parts might damage your system.

 Re-insert the repaired fan module into the system.

See to it that the fan module plugs properly into the sys­tem’s fan interface and that, when completely inserted, the
locking mechanism snaps back into its locked position.

Maintenance

 Next close the casing of the system as described in section “Clos-

ing the Casing” on page 5-8.

5.4 Controller Maintenance

During the service life of the DVS system you may have to exchange a
RAID controller (see section “Introduction to RAID” on page 5-2). It
may be indicated, for example, if a disk set (RAID pack) cannot be ac­cessed anymore. This section describes how to exchange a RAID con­troller.

Before exchanging a RAID controller contact the DVS service
department.

The system you are working on operates with voltages
that can be hazardous to your health. Never work on the
system or access its interior with the power cable(s) being
plugged in. Make sure the power supply is disconnected
from the components you intend to work on.

Maintenance inside the system should only be performed
by personnel qualified for handling and testing electrical
equipment.

Computer hardware contains components that are sensitive
to electrostatic discharge. If you touch them without precau­tionary measures, they can be destroyed. Use a wrist strap
connected to ground when accessing electronic parts and
take care of grounding the system. Avoid touching the inter­nal components of the computer system.

 Identify the controller or disk set that causes the problem, for exam-

ple, by consulting the RAID software manager.

 Then, open the casing of the system as described in section “Open-

ing the Casing” on page 5-8.

To reach the RAID controllers you may have to remove an air
duct which is fastened to the system with several screws.

 On the defective controller memorize the order of the cables that

are connected to it. To make this easy the cables are numbered.

 Disconnect the cables connected to the controller.

 Remove the defective controller from the system and in its place

install a new one.

Only use original manufacturer spare parts. Other spare
parts might damage your system.

5-12

The controller must have the same firmware installed as
the other controllers.

 Connect the cables to the controller again in the same manner as

they were on the old controller.

 Next close the casing of the system as described in section “Clos-

ing the Casing” on page 5-8.

Maintenance

With the last step finished you have successfully replaced the defective
RAID controller. Now, you have to integrate the new controller in the ex­isting configuration:

 Turn on the system as described in section “Starting the System”

on page 4-1.

After the initial booting you will see something like the following on the
screen:

Following foreign Arrays are found:
Array#<x>-RAID-<y>

Press <Enter> to accept the current configuration
Press <CTRL-A> to enter RAID Configuration Utility
Press <CTRL-H> to Pause Configuration Messages
(Default is not to accept if no valid key pressed in 30
seconds)

 Press [Enter] on the keyboard to accept the configuration detected

by the system:

1

<Enter> pressed: The current configuration is accepted

After this the newly installed RAID controller automatically initiates a
verify of the connected hard disks which may take some time. When
finished, the system will continue its booting procedure until the oper­ating system is fully loaded. You may then continue your work with the
system.

5.5 Power Supply Maintenance

The redundant power supply provides the system with power. It is a re­liable and enduring part of the system because it consists of several in­dependent power supply units: Even if one fails the others will still offer
enough power to keep the system working.

The system can be operated with one power supply unit out
of order. However, if another one fails, a continued operation
of the system cannot be guaranteed. Therefore, it is recom­mended to change a failed power supply unit immediately.

When a power supply unit failure occurs, you will be notified by a lit
alarm LED and the sounding of an alarm buzzer of the system. The
alarm can be switched mute with the mute button at the front of the
system (see section “Operation Items” on page 2-4).

An alarm can be caused by a number of reasons. Please refer
to section “Troubleshooting” on page A-2 first for further de­tails about what to do in case of an alarm.

Compared to other alarms sounded by the system the alarm
buzzer of the power supply is relatively faint. In a loud environ­ment it may be drowned by other noises. When operating the
DVS system in a loud environment, it is recommended to
check the state of the alarm LED (see section “Operation
Items” on page 2-4) at regular intervals.

Each power supply unit in the DVS system is hot-swappable, so you
can safely replace it with the system running. Follow these steps to re­place a power supply unit:

For an overview of a power supply unit see section “Power
Supply” on page 2-20.

 Take a look at the power supply at the rear of the system and exam-

ine the LEDs of the units. The LED of the malfunctioning power
supply unit should be extinguished.

 Next unplug the power cord from this power supply unit.

 Unscrew the security screw of the latch.

 Take the handle of the respective unit and press the unit’s latch to

the left to unlock it.

 Then pull the unit at its handle out of the power supply.

5-14

Do not reach inside the system when removing a power
supply unit or when the unit is out of the system.

 Change the power supply unit against a new and operable one.

Maintenance

 Slide the new unit into the power supply until it clicks into place.

Only use original manufacturer spare parts. Other spare
parts might damage your system.

When completely inserted please observe that the latch is
truly in place and locking the unit.

 Tighten the security screw of the latch again.

 Connect the power source (power cord) to the newly installed

power supply unit.

 After that check the LED indicating the status of the power supply

unit: If it is lit up in green, the unit is working properly.

With this the power supply unit has been replaced successfully.

5.6 Backup or Recovery of the System Disk

The DVS system provides internally a USB flash drive that can be used
to back up or restore the operating system on the system hard disk.
With it you can, for example, set the system disk back to its manufac­turing state. Once selected as a boot device, it will launch a Live Linux
which in turn will either back up or restore the system hard disk. The
following sections describe how to create a backup image or perform
a recovery of the system disk.

5.6.1 Creating a Backup Image of the System Disk

The following describes the steps to make a backup image of the sys­tem hard disk and save it to the internal USB flash drive:

Do not execute any commands if you are not sure about the
correct source and target device. For example, selecting the
wrong source device could lead to a full storage space and a
termination of the process.

To complete the loading of the DVS Rescue environment
some user entries are required. For this follow the instructions
given on the screen.

The loading of the environment and the recovery process itself
will both try to initialize hardware that may not be present on
your system. Any error messages displayed during loading/ini­tialization, e.g. Failed or Warning, can be disregarded. The
recovery process should work nonetheless.

The storage space on the USB is limited. The number of back­up images that can be stored on the drive, besides the DVS re­covery image ex factory available, depends on the size of the
image files. If the process fails, the storage drive may be full.
However, an already created image can be overwritten when
assigning the same name to it.

 If appropriate, disconnect all Fibre Channel cables and all externally

connected storage devices from the system.

 Turn on or restart the DVS system and at the indicated moment dur-

ing start-up press [F11] on your keyboard to enter the boot menu.

 Once the boot menu is displayed on the screen, select the internally

installed USB flash drive as the boot device and then press [Enter]
on your keyboard.

5-16

With this the target device has been selected. The system will now boot
from the internal USB and you will see a window on the screen where
you can select the DVS Rescue environment for loading:

 Select DVS Rescue and press [Enter] on your keyboard.

If you do not perform any action, DVS Rescue will be loaded
automatically after 30 seconds.

Once the loading has finished, you will see the DVS Rescue script with
its options on the screen. Your display should look similar to the follow­ing:

--- DVS Rescue ---

1 - Backup on internal USB device
2 - Restore from internal USB device
3 - Reboot the system
4 - Poweroff the system

0 - Exit

Enter selection:

 To make a backup image of your system disk and save it to the

internal USB, press [1] and then [Enter] on your keyboard.

Afterwards a list of possible source devices will be detailed on the
screen. In a VENICE, the system device normally will be ’sda’, but on
special systems it may also be ’sdb’, ’sdc’, etc. Pay attention to the dis­play on the screen. The correct system disk should be the one named

VENICE_system. For example, if your display shows:

[0:0:0:0] disk Adaptec VENICE_system V1.0/dev/sda,

1

or a similar line, the respective system disk should be ’sda’.

Ex factory the DVS system will be delivered with ’sda’ as the
default system disk. If other configurations have been made
later or on customer request, this may be different.

Continue with the following steps only, when you are able to
identify the correct source device.

 Enter the name of the system disk in the designated line. Just type

in sda (in other cases sdb or sdc) and press [Enter] on your key­board.

The system will now ask you to enter the image name for the backup
image to be saved to the USB. By entering the name of an already ex­isting backup image you can overwrite it.

 Type in the name of the image you want to save to the USB for a

later recovery. To confirm your entry press [Enter] on your keyboard.

The system will ask you to confirm your selection and whether you
want to continue:

If during the process the screen turns black, press [Space] to
get it back again.

When the system has finished the backup process, you will be notified
about this. Then after pressing [Enter] on your keyboard, you will be re­directed to the DVS Rescue script once more where you can choose,
for example, ’reboot’ or ’poweroff’ to restart or turn off the system.

To abort the process at this point enter n for ’no’ and press
[Enter] on your keyboard. You will be redirected to the DVS
Rescue script.

After starting the process its termination is not possible any­more.

5.6.2 Restoring the System Disk

The following describes the steps to make a recovery of the system
hard disk:

Do not execute any commands if you are not sure about the
correct source and target device. For example, selecting the
wrong target device can lead to a total loss of data.

To complete the loading of the DVS Rescue environment
some user entries are required. For this follow the instructions
given on the screen.

The loading of the environment and the recovery process itself
will both try to initialize hardware that may not be present on
your system. Any error messages displayed during loading/ini­tialization, e.g. Failed or Warning, can be disregarded. The
recovery process should work nonetheless.

Please contact the DVS service department if you are not sure
whether you are able to identify the correct target device.
