Before you start
HP StorageWorks DAT models
This guide describes how to install and operate the following HP StorageWorks DAT models:
•HPStorageWorksDAT72x6
•HPStorageWorksDAT40x6
Which operating systems are supported?
HP StorageWorks DAT autoloaders can be connected to servers running under Windows®,
NetWare, UNIX, Tru64 and Linux. Refer to the “HP StorageWorks Tape Software
Compatibility” topic on our World Wide Web site (
information about the operating system versions that are supported.
How do I connect the autoloader to my server?
The following guidelines apply:
• For optimum performance the autoloader should be the only device on the SCSI bus.
• Always terminate the SCSI bus.
• Do not attach the autoloader to the same SCSI bus as a your disk drive or to a RAID
controller.
www.hp.com/go/connect) for more
You will need a properly installed and configured SCSI host bus adapter (HBA) or a built-in
SCSI controller on your server. Your autoloader is supplied with a VHD-to-HD cable to attach
the drive to a spare, external VHD SCSI port on the server. It is also shipped with a multimode
terminator. The cable and terminator are appropriate for a wide, low voltage differential (LVD)
or single-ended (SE) SCSI bus.
If the SCSI cable supplied with your autoloader is not appropriate for your server’s external
SCSI connector, you will need to order an adapter or new cable. See also "Checking the
SCSI connection" on page 9.
Why is the SCSI bus type important?
The SCSI bus type determines the speed at which data can be transferred between devices on
the bus and the maximum length of cable that can be used. The autoloader supports a burst
transfer rate of 40 MB/sec. To benefit from this level of performance, it is important to ensure
that the devices are connected to a SCSI bus of a similar or higher specification. This means
that you need:
• An Ultra Wide, Ultra2 Wide, Ultra3 (160) or Ultra4 (320) SCSI bus. Ultra Wide SCSI
supports the maximum bus speed of 40 MB per second; Ultra2, Ultra3 and Ultra4 SCSI
exceed this.
• LVD-rated SCSI cabling and terminators. The LVD interface enables the data to be
transferred at the device's maximum rate.
If you attach the device to a lower specification SCSI bus, it may still work but data will not be
transferred as quickly.
The devices are not compatible with high voltage differential (HVD) SCSI devices.
3
How can I check the SCSI bus type and SCSI ID?
For many operating systems, you can install HP Library & Tape Tools from www.hp.com/
support/tapetools
configuration (see page 37). This will provide information about the SCSI bus and the SCSI
IDs in use. See also the SCSI topic in the electronic User’s Guide on the
HP StorageWorks Tape CD-ROM for other ways of checking the SCSI bus type.
and run the “Install Check” to check your server’s current SCSI
Do I need additional items for installation?
• If you have an HD rather than a VHD, wide, SCSI connector on your server, you will need
to purchase and install a VHD-to-HD adapter or use an HD-to-HD cable instead of the
supplied cable.
• If you do not have a spare, suitably-rated SCSI connector on your server, you must install a
new HBA (also known as a SCSI card). This should be of an Ultra Wide or higher SCSI
specification. We recommend that a 64-bit Ultra 3 (160) HBA is used. For specific details
relevant to your server model please refer to
to purchase and install the new HBA into an unused, 64-bit PCI expansion slot within your
server before installing your autoloader. (The kit can also be installed in a 32-bit PCI
expansion slot, but performance may be degraded.)

Backup software and drivers
Backup software
For optimum performance it is important to use a backup application that is appropriate for
your system’s configuration. In a direct attach environment, where the autoloader is attached
to a standalone server, you can use backup software that is designed for a single server
environment. In network configurations you will need backup software that supports enterprise
environments. HP, Veritas, Legato, Yosemite and Computer Associates all provide suitable
products. Further details about these and other products that may be appropriate can be
found on our connectivity web site.

Checking the SCSI connection
Use the following questions to help you check your SCSI connection. Many users can use HP
Library & Tape Tools to check the SCSI bus type, see page 37. If you answer ‘Yes’ to all these
questions, you are ready to install your autoloader. If you answer ‘No’, you will probably
need to purchase and install additional items. For compatibility and product details, go to
www.hp.com/go/connect.
1 Is there a spare SCSI port on your
server?
Yes
2 Is the SCSI bus type correct for the
SCSI specification of the device?
Yes
3 Will the autoloader be the only
device on the bus? This is the
recommended configuration. Do
not connect to a RAID controller or
the same SCSI bus as your disk
drive.

Purchase and install one of the recommended
HBAs into an unused 64-bit PCI expansion
slot. (The HBA can also be installed in a 32bit PCI expansion slot, but performance may
be degraded.)
See table below. If the SCSI bus differs from
the recommended specification for the drive,
performance of either the drive or the bus may
be impaired. Consider replacing your card
with one of the recommended HBAs.
If you have an Ultra HBA, performance may
be impaired. Consider installing (if you have
a spare PCI slot) or replacing your card with
an Ultra2, Ultra3 (160) or Ultra4 (320) HBA.

Figure 3: checking the autoloader’s SCSI ID
Step 1: Check the autoloader’s SCSI ID
Note Your HP StorageWorks DAT autoloader is shipped with a default SCSI ID of 5. Each device on
the SCSI bus must have a unique SCSI ID number. The autoloader can be assigned any
unused ID between 0 and 15. Do not use SCSI ID 7, which is reserved for the SCSI controller.
SCSI ID 0 is typically assigned to the boot disk and should also not be used unless the
autoloader is on a dedicated SCSI bus.
1 Determine whether you need to change the SCSI ID from the default of 5.
For many operating systems you can install HP Library & Tape Tools from the
HP StorageWorks Tape CD-ROM and run the “Install Check” to check your server’s current
SCSI configuration (see page 37). This will provide information about the SCSI bus and the
SCSI IDs in use.
The UNIX Configuration Guide on the HP StorageWorks Tape CD-ROM also contains
instructions on how to determine the SCSI IDs of existing devices on UNIX servers.
2 Change the autoloader’s SCSI ID, if necessary.
Use a small screwdriver or a ball-point pen to press the indented SCSI ID selector buttons on
the rear panel (see figure 3) until the required value is displayed. Do not use a pencil because
small bits of graphite could contaminate the drive.
Note The server and the autoloader SCSI IDs are only checked at power-on. To change the SCSI ID
after installation, power down both the server and the autoloader, change the autoloader’s
SCSI ID, power up the autoloader, and then power up the server.

Step 2: Check the option switch value (Sun systems only)
Only read this section if you are installing your autoloader into a Sun workstation system
running Solaris version 2.6 or below. Go to step 3 if you are using your autoloader on a
UNIX system, or straight to step 4 if you are using your autoloader on a Windows PC system.
The option switch setting is used to configure the autoloader for specific systems. The default
of 7 is correct for most systems and is only changed for Sun workstations or servers running
Solaris v. 2.6 or below.

Figure 6: attaching SCSI cable
Step 4: Attach SCSI cable
A wide VHD-to-HD SCSI cable is provided to connect your HP StorageWorks DAT autoloader
to a VHD SCSI port on an LVD SCSI bus. If your server has an HD SCSI port, you must either
purchase and install a VHD-to-HD adapter or use an HD-to-HD cable instead of the supplied
cable. Refer to our web site for recommended products:
Caution To avoid damaging the server or autoloader, ensure that both are powered off while you
attach the SCSI cable.
1 Make sure you are connecting to a recommended SCSI bus type. See “Checking the SCSI
connection” on page 9. Do not connect the autoloader to the same bus as a RAID controller.
For optimum performance, we recommend that your HP StorageWorks DAT autoloader is
installed on a dedicated SCSI bus. If it is not, do not connect it to the same bus as your disk
drive.
2 Perform a normal system shutdown and turn off the server and any connected peripherals.
3 Attach the VHD connection on the SCSI cable to the server’s external SCSI connector and
secure it by tightening the screws.
4 Attach the HD connection on the SCSI cable to one of the SCSI connectors on the rear panel
of the autoloader and secure it by tightening the screws.(See figure 6.)
5 Connect the multimode terminator to the autoloader’s other SCSI connector and tighten the
screws to secure it. The multimode terminator detects whether the host bus adapter is SE or LVD
and automatically provides the appropriate termination.
www.hp.com/go/connect.
Why does the autoloader need a terminator?
Terminators are essential, as they provide the correct voltages on the SCSI bus and prevent
unwanted signal reflections from interfering with data transfers. The rule is:
There must be termination at both physical ends of the bus and only at the ends.
Normally the HBA forms one end of the SCSI bus and provides termination. You, therefore,
need to ensure that the other end of the bus is terminated. If the autoloader is at the end of
the SCSI bus, the terminator must be attached to the autoloader.
If you want to attach additional devices to the SCSI bus after the autoloader, you will need
to remove the SCSI terminator and attach the next device to this SCSI connector. Make sure
that you attach the terminator to the last device in the chain.
17

Figure 7: attaching the power cable
Step 5: Attach power cable
An external HP StorageWorks DAT autoloader will operate using any voltage in the range
100–240 volts (0.7 A, 50-60 Hz). No adjustment is needed. To connect your autoloader to
the power supply, proceed as follows:
1 Make sure that the autoloader is switched OFF. The power switch is on the rear panel.
2 Plug the power cable securely into the socket on the rear panel of the autoloader. (See figure 7.)
3 Plug the other end of the power cable into the power outlet.

Step 6: Verify installation
Once you have installed the drive hardware, you should verify that it is functioning properly
before you store your valuable data.
Check operation
Ensure that you have downloaded any drivers and upgrades necessary for your backup
application (see page 5).
1 Switch on the autoloader and server.
The power indicator will light up and the autoloader will run its hardware self-test, during
which the front panel lights will flash and the message
also displays the serial number; the display alternates between the
and the serial number. At the end of the self-test, all lights will go out and the front panel
message will say
electronic User’s Guide on the HP StorageWorks Tape CD-ROM.)
If the self-test fails, the Operator Attention Required light (bottom) changes to steady amber
and the other lights go off. If this occurs, try switching the autoloader off, then on again. If the
test still fails, call for service.

To load a magazine
1 Place the required number of cartridges in the magazine so that they point towards the center
of the magazine. You can use any number of cartridges from 1 to 6, and can place the
cartridges in any of the magazine slots. However, for ease and speed of use, start by using
slot 1. (HP OBDR requires a cartridge in slot 1, see page 36.)
2 Insert the magazine through the door in the front of the autoloader. Make sure that the large
arrow is uppermost and pointing towards the autoloader, as shown in figure 8.
3 Apply steady pressure until the mechanism takes the magazine and pulls it into the autoloader.
The autoloader will then check which magazine slots contain cartridges.
4 When the magazine check is complete, use either your backup software on the host server or
the autoloader's front panel buttons to select and load a cartridge from the magazine into the
drive.
5 The drive now performs a load sequence. This takes a maximum of 25 seconds from the time
the cartridge is inserted to the time the drive is ready to start acting upon the next command
from the host. See the electronic User’s Guide on the HP StorageWorks Tape CD-ROM for more
information about the load sequence and autoloader modes.

Figure 9: unloading the autoloader
To unload a magazine
1 Press the Eject button on the front panel. (See figure 9.)
2 The autoloader ejects the magazine. However, if one of the cartridges is still in the drive
mechanism when you press the Eject button or the autoloader is busy, it may be a long time
before the autoloader will respond to the request because it will finish the task it is performing
first. This ensures that the task is terminated in a controlled manner and no data is lost.
Note It is possible for the host server to disable the Eject button by sending a PREVENT MEDIA
REMOVAL command via SCSI. This will remain in force until either the host sends an ALLOW
MEDIA REMOVAL command or the autoloader is reset or power-cycled.
Autoloader modes
HP StorageWorks DAT autoloaders may be operated in either stacker or random mode.
Mode is initially determined by what happens after you insert a magazine:
• If the host sends a command to move a cartridge from the magazine to the drive, the
autoloader goes into random mode
• If you select a cartridge by pressing the Select button and then load it by pressing the Load
Cartridge button, the autoloader goes into stacker mode
See the electronic User’s Guide on the HP StorageWorks Tape CD-ROM for more information
about autoloader modes.

Figure 12: DDS media
Use the correct media
In order to maximize drive and media reliability, normally use the autoloader to provide one
week's backup per magazine. Ideally, use five cartridges and one cleaning cartridge in each
magazine. This allows you to perform a full backup, up to 40 (DDS-4) GB or 72 (DAT 72) GB
each working day, and ensures that the tape heads are cleaned once a week.
For best performance we recommend HP branded media. Order online at:
www.hp.com/go/storagemedia
Guide on the HP StorageWorks Tape
and cleaning cartridges.
Data cartridges
For optimum performance and storage capacity, use tape cartridges that match your drive's
format, and use only one brand and type (tape length) of data cartridge in a magazine. For
example, do not use DDS-4 (150m) cartridges with DAT 72 (170m) cartridges. Ideally, use
HP’s DDS-4 cartridges with DAT 40x6 autoloaders and HP’s DAT 72 cartridges with DAT 72x6
autoloaders.
Although HP StorageWorks DAT autoloaders are fully backward compatible, old tape formats
are more abrasive than later generations and using older tape formats can reduce the life
expectancy of the autoloader. The compatibility between drive models and cartridges is
summarized in the following table. Shaded boxes show the recommended media for each
autoloader.

Write-protecting cartridges
If you want to protect the data on a cartridge from being altered or overwritten, you can writeprotect the cartridge. (See figure 13.)
Always remove the cartridge from the autoloader before you change the write protection.
• To write-protect a cartridge, slide the tab on the rear of the cartridge so that the recognition
hole is open.
• To write-enable a cartridge, slide the tab back so that the hole is closed.
Write-protection will not protect your cartridges against magnets (or bulk erasers).

To clean the tape heads
HP recommends weekly cleaning of the autoloader using an HP cleaning cartridge (part
number C5709A). Do not use swabs or other means of cleaning the heads. The cleaning
cartridge uses a special tape to clean the tape heads. A cleaning cartridge can only be used
50 times or as instructed on the cartridge packaging. Always place a check mark in a box
each time you use the cartridge to clean the drive. Replace the cleaning cartridge when all
the boxes are checked. New cleaning cartridges are available from HP.
In addition to regular cleaning, use a cleaning cartridge under the following circumstances:
• When a "Clean Me" message is displayed on the front panel and the Operator Attention
Required light flashes amber.
• When your backup application warns you that the drive needs cleaning (providing your
backup application supports the TapeAlert feature).
Cleaning the tape heads on an HP StorageWorks DAT autoloader can be performed
manually by the user or automatically by the backup application.
Manual method
1 Place a cleaning cartridge in any magazine slot and note the slot number.
2 Insert the magazine into the autoloader.
3 Press the Select button until the slot number where the cleaning cartridge is located is
displayed.
4 Press the Load Cartridge button to load the cleaning cartridge into the drive. The drive will then
automatically perform the cleaning cycle. The LCD display will display the message "Cleaning"
while the cartridge is in use.
5 Eject the magazine and mark the label on the cleaning cartridge to keep a record of how many
times it has been used.
Automatic cleaning
Certain backup applications that provide autoloader support have provision for automatic use
of the cleaning cartridge. In this case the cleaning cartridge is put in a magazine slot (usually
slot 6). The application can then be told that slot 6 contains the cleaning cartridge and also
when it is to be used. The magazine is then loaded in the usual way and the cleaning
cartridge is used at intervals programmed into the application.

Handling cartridges
• Do not touch the tape media.
• Do not attempt to clean the tape path or tape guides inside the cartridge.
• Do not leave cartridges in excessively dry or humid conditions. Do not leave cartridges in
direct sunlight or in places where magnetic fields are present (for example, under
telephones, next to monitors or near transformers).
• Do not drop cartridges or handle them roughly.
• Do not stick more than one label onto the cartridge label area; extra labels can cause the
cartridges to jam in the drive. Stick labels onto the label area only.
• Make sure that the magazine label is stuck firmly in the recessed label area on the side of
the magazine. If the label is stuck somewhere other than in the label area, the magazine
may jam in the mechanism.
• See the insert included with the tape cartridge for storage conditions.
Getting the most out of cartridges and drives
• Use mostly the latest media type (DDS-4 media for an HP StorageWorks DAT 40x6
autoloader, DAT 72 media for an HP StorageWorks DAT 72x6 autoloader).
• Use media for the recommended number of times (100 backups). Overuse of the tape will
cause it to degrade and possibly shed tape debris in the drive. Too many new tapes can
also cause wear of the drive as they are rougher than used ones.
• Do not verify (DDS does read-after-write checking automatically).
• Do not overload the server during backups. Maximize the transfer rate (run overnight with
no other processes) and use incremental backups if convenient.
• Do not overuse your autoloader—it is designed for approximately four hours of tape pulling
per day, not constant usage—and clean the drive regularly. See page 31.

Using HP OBDR
Compatibility
HP One-Button Disaster Recovery is a standard feature on all HP StorageWorks DAT
autoloaders. However, it can only be used with specific configurations and will only recover
the server to which the autoloader is directly connected.
To check whether your system (hardware, operating system and backup software) is OBDRcompatible, please refer to our World Wide Web site
For more specific information concerning the benefits of OBDR and the latest new features
please refer to our World Wide Web site
www.hp.com/go/obdr.
Note HP OBDR is not applicable to HP-UX and other non-Intel UNIX operating systems, and it is not
compatible with Intel-based Solaris systems. HP OBDR is supported on a server with a RAID
controller if the autoloader is connected directly to a host bus adapter (HBA).
If your system does not support HP One-Button Disaster Recovery, you can still use your
autoloader normally to back up and restore data. However, you must remember to create a
separate set of emergency recovery disks for your operating system whenever you change
your system configuration.
What does HP OBDR do?
Using just the autoloader and the most recent backup cartridge HP OBDR allows you to
recover from the following types of system disaster:
• Hard disk failures, as long as the replacement hard disk is the same size or larger than the
original and uses the same interface (for example, replace a SCSI hard disk with another
SCSI disk)
• Hardware failures where the server is replaced by an identical component
• File corruption because of an operating system error
• File corruption because of an application software error
• Viruses that prevent you from booting your system correctly
• User errors that stop you from booting your system correctly
When you run HP One-Button Disaster Recovery, your autoloader goes through the following
sequence:
1 It goes into a special disaster recovery mode that enables it to restore your operating
system and reboot. It acts like a bootable CD-ROM. (Your system’s ability to boot from
CD-ROM is normally enabled by default. If you have changed this setting, you will need
to enable it again. Refer to your system BIOS manual for further details.)
2 It returns to normal autoloader mode and restores the data.
www.hp.com/go/connect.
Remote disaster recovery (ProLiant servers only)
The HP Remote Insight Lights-Out Edition (RILOE) on ProLiant servers gives the IT Administrator
the ability to completely recover a failed server at a remote location without physically
traveling to where the server resides. The on-site non-technical person need only insert the
bootable cartridge into the autoloader when asked to do so by the administrator.
Refer to the HP OBDR web site at
this feature and compatibility.
www.hp.com/go/obdr for more information about using
35
Testing for compatibility
We recommend that you perform a full disaster recovery immediately after installation—if
possible, onto a blank hard disk. If you do not have a blank hard disk and do not want to
overwrite your system, you can safely cancel the disaster recovery process at step 4 in the
following procedure.
Refer to our connectivity web site (
suitable backup applications.
www.hp.com/go/connect) for more information about
Running HP OBDR
HP OBDR can only be used with backup applications that support one-button disaster
recovery and methods of operating OBDR will vary between different software companies.
Check our World Wide Web site (
software compatibility, firmware upgrades and troubleshooting before you use HP OBDR.
1 Insert the latest bootable cartridge in slot 1 of the magazine and put it in the autoloader (see
figure 14a). The cartridge must be written by a backup application that writes data to tape in
CD-ROM format.
Note Note: The cartridge in slot 1 of the magazine is always used to restore your operating system
to a state where it can run a normal data restore from the most recent backup cartridge in the
magazine.
2 Hold down the eject button. Keeping the eject button pressed down, power on your autoloader
(see figure 14b). This puts the device into HP One-Button Disaster Recovery mode when you
power on. Release the button as soon as the LCD displays the message "OBDR Mode".
www.hp.com/go/obdr) for the latest information about
Keyboard shortcut for HP ProLiant servers
There is no need to press the Eject button. Just power on your server and press the [F8]
function key during the Power On Self Test (POST). This invokes OBDR to restore your system.
For more information and specific instructions please refer to our World Wide Web site at
www.hp.com/go/obdr.
3 Switch on your server (see figure 14c).
4 Follow the on-screen instructions to set up the operating system (see figure 14d). (These will
vary depending upon the backup software.) Normally, you can accept the default response to
all the prompts, for example just press <Enter>.
The LCD displays the message "OBDR Mode" while the autoloader restores your operating
system to a state where it can run a normal data restore. Once the operating system has been
set up and rebooted, the LCD "OBDR Mode" message disappears and the Magazine Present
and Tape Activity LEDs display constant green.
5 The operating system has been restored to the point of the last full system backup created from
your OBDR cartridge. Follow the normal process for your restore application.
If restore fails
If the restore fails for any reason, refer to our World Wide Web site (www.hp.com/go/

37
Optimizing performance
Various factors can affect autoloader performance, particularly in a network environment or if
the drive is not on a dedicated SCSI bus.
If your autoloader is not performing as well as expected, consider the following points before
contacting HP Support at
• Is the autoloader connected to a suitably-rated built-in SCSI bus or HBA, see “Why is the
SCSI bus type important?” on page 3. Suitably-rated means an Ultra Wide or higher SCSI
specification, such as an Ultra 160 SCSI Host Bus Adapter.
• Is the autoloader on a dedicated SCSI bus? For optimum performance, we recommend that
the autoloader is the only device on the SCSI bus. If it is not, ensure other devices are the
same SCSI specification as your autoloader model. If they are single-ended, the bus will
switch to single-ended mode with a lower transfer speed.
• Do not put autoloaders and hard disks on the same SCSI bus.
• Is the SCSI bus terminated correctly. The last device on the SCSI bus must be terminated.
• Have you installed the correct device drivers for your operating system and backup
application? See “Backup software and drivers” on page 5.
• Are you backing up across a network? The network load may be affecting the speed of
transfer or your backup application may only be appropriate for a single-server
environment.
• Is the backup application writing buffers at the correct speed? You may need to tune the
transfer, buffer and block size settings to optimize the speed that the application writes data
to the autoloader. HP StorageWorks DAT autoloaders have an internal buffer of 8 MB.
www.hp.com/support.
38
Troubleshooting
The first step in problem-solving is establishing whether the problem lies with the cartridge, the
drive, the host server and its connections, or with the way the system is being operated.
Most modern SCSI host bus adapters locate and display attached devices when the system is
booting up. On Windows systems, if you swap or connect a product when your system is
running, you will need to reboot the system. IA32 systems also usually need to be rebooted.
UNIX systems may have pluggable drivers, which allow drives to be attached to a running
system and detected without rebooting.
If the device is not detected on boot up, there is probably a problem with the physical
hardware: cables, termination, connections, power or the host bus adapter itself. If the device
is displayed during boot up but cannot be found in the operating system, this is more likely to
be a software problem.
• If you encounter a problem during installation and need further clarification, refer to
“Problems encountered during installation” below.
• If a problem arises during testing after you have installed the drive, refer to the symptombased section “Testing after installation” on page 41.
Many users can use HP Library & Tape Tools to help them diagnose problems.
Problems encountered during installation
Unpacking
Description Further information
Some parts appear to be missing or
damaged.
Contact your vendor if any parts need replacing.
The SCSI cable shipped with the drive is not correct
Description Further information
The SCSI cable shipped with the drive does
not plug into the SCSI host adapter of the
server.
The cable provided will connect to the majority of
systems. If a different cable is required, refer to the
www.hp.com/go/connect web site.
It is unclear which SCSI ID to use
Description Further information
It is uncertain which ID numbers are
available.
Use HP Library & Tape Tools (see page 37) to provide
information on your current SCSI settings.
The HP StorageWorks DAT autoloader has its SCSI ID
set to 5 by default. This should be left unchanged
unless this number is already in use. Full instructions
on how to change the SCSI ID are given on page 11.
39
How should the SCSI bus be configured?
Description Further information
Correct configuration of the SCSI bus with
multiple drives can be a complex area and
more help may be required.
Refer to the SCSI Configuration section in the
electronic User’s Guide on the
HP StorageWorks Tape CD-ROM.
How should the SCSI bus be terminated?
Description Further information
It is unclear if the bus is already terminated
or where an additional terminator should
be placed.
Both ends of a SCSI bus must be terminated.
Assuming that the host bus adapter is already
correctly terminated, there are typically three
possibilities:
• The autoloader is the only external device on the
SCSI bus. It should be terminated with the terminator
provided.
• The autoloader is being added to the end of a chain
of one or more existing external d evices. Remove the
terminator from the last device on the existing chain,
connect the autoloader to the chain, and terminate
the autoloader with the terminator provided.
• The autoloader is being added to the middle of a
chain of existing external devices. Insert the
autoloader into the chain and do not use the
terminator provided.
The terminator plugs directly onto either SCSI
connection on the rear of the autoloader.
Refer also to the SCSI Configuration section in the
electronic User’s Guide on the
HP StorageWorks Tape CD-ROM.
40
Is the correct SCSI host bus adapter installed?
Description Further information
The server already has a SCSI host bus
adapter but it is difficult to determine what
type it is.
The server may not have a SCSI host bus
adapter installed.
If your server is in its original configuration (no SCSI
adapters have been added or removed) then use
www.hp.com/go/connect to check the
compatibility of your system. You can also check the
SCSI configuration from the boot-up screen or from
the Windows Control Panel, or by using HP Library &
Tape Tools (see page 37).
Use HP Library & Tape Tools (see page 37) to check
whether you have a SCSI host adapter on your
system. If not, you will need to purchase one. Refer to
www.hp.com/go/connect web site.
the
Do drivers need to be installed and, if so, which ones
Description Further information
It is unclear whether there is a need to
install drivers onto the system, and more
help is required.
Detailed information specific to your system can be
found on the www.hp.com/go/connect web site.
Windows drivers can be obtained from the
HP StorageWorks Tape CD-ROM or from
www.hp.com/support. For support on UNIX
systems, see the UNIX Configuration Guide on the
HP StorageWorks Tape CD-ROM.
(Backup software that states support for
HP StorageWorks DAT autoloaders also provides
the required drivers.)
The required drivers do not appear to be
available.
Future drivers will be provided via the support web
site when they become available.
Testing after installation
Remember that the system recognizes devices during boot-up. If you swap or connect a
product when your system is running, you will need to reboot the system. Rebooting the system
will reset devices and will often resolve problems. It is good practice to reboot every time you
add a driver or install firmware.
Caution Never power off the drive during a firmware upgrade.
The server does not reboot after installation
Possible reason Recommended action
You have installed an additional SCSI host
bus adapter and its resources are clashing
with an existing adapter.
You have disconnected the power or SCSI
cable from the server’s boot disk during the
drive installation process.
Remove the new host bus adapter and check the
server documentation.
Check that the cables to all devices are firmly
connected.
41
The server boots but does not recognize the autoloader
Possible reason Recommended action
The power or SCSI cable is not connected
properly.
Check that the cables to the autoloader are firmly
connected. Ensure that the SCSI cable does not have
any bent pins. Replace, if necessary. (Refer to the
www.hp.com/go/connect web site.)
The SCSI bus is not terminated correctly. Check that the SCSI bus is actively terminated. (Refer
also to the documentation for your SCSI controller
and any other SCSI devices you may have.)
The autoloader’s SCSI ID address is not
unique.
The autoloader was switched on after the
server booted up. The server only checks for
SCSI devices at power-on.
Make sure that each device on the SCSI bus has a
unique ID.
We recommend that the HP StorageWorks DAT
autoloader is connected to a dedicated host bus
adapter. Do not connect the drive to a disk RAID
controller as this is not supported.
Switch on the autoloader and then reboot the server.
The application does not recognize the autoloader
Possible reason Recommended action
The application does not support the
autoloader.
Some applications require drivers to be
loaded.
Use HP Library & Tape Tools to check that the drive is
installed properly. Refer to our World Wide Web site
www.hp.com/go/connect) for details of
(
backup applications that support the
HP StorageWorks DAT autoloader. Load any service
packs as necessary.
Check that the correct SCSI and autoloader drivers are
installed. Consult the backup application’s installation
notes for details.
42
The autoloader does not work
Possible reason Recommended action
If the drive does not power up, the power
cable may not be connected to the
autoloader properly.
If the self-test fails, (Operator Attention
Light is steady amber), there may be a
hardware or firmware failure.
Make sure that the power switch and LED are on and
that the power cables are firmly connected. If they are,
the device has probably failed. Call for service.
Power down the autoloader and power it up again. If
the self-test still fails, see “Understanding the OAR
LED” on page 43.
Understanding the OAR LED
The amber Operator Attention Required LED indicates warning conditions, as described in the
following table:
LED display Meaning
On A serious hardware error has occurred.
Fast flashing (four times per
second)
Medium flashing (twice per
second)
Slow flashing
• If you have just installed the autoloader, check the installation
for loose connections and repeat the self-test. One of the two
power cables may not be connected. (An autoloader requires
two power connections: one for the autoloader and one for
the robotics.) If this is the problem, the front panel message is
Coms Error.
• Run HP Library & Tape Tools to determine what the problem is.
• If the fault condition persists, write down the message
displayed on the front panel and call for service.
A firmware upgrade is taking place.
• The tape cartridge is wearing out and should be replaced.
The "Worn Media" message will be displayed in this case.
Copy any data you wish to keep onto a new cartridge and
discard the old cartridge.
• The tape heads need cleaning. The "Clean Me" message will
be displayed in this case.
• The front panel door is open when it should not be. The "Close
Door" message will be displayed in this case.
• There is a cartridge in the autoloader, but no magazine is
present. The "Stray Tape" message will be displayed in this
case. Load an empty magazine to retrieve the cartridge.
• A hard fault condition has occurred. The message displayed
will give information about the type of error. Look up the
message in the electronic User’s Guide on the
HP StorageWorks Tape CD-ROM to determine what to do.
43
Forcing ejection
If you press the Eject button when the autoloader is busy, it may be a long time before the
autoloader will respond to the request because it will finish the task it is performing first.
However, if you need to unload a cartridge urgently, even at the risk of losing data, you must
force ejection.
Caution You can lose data if you force ejection. The tape may also end up invalidly formatted because
an EOD (End of Data) mark might not be written. Force ejection only as a last resort to recover
a cartridge.
1 Hold the Eject button down for at least five seconds (usually between 5 and 10 seconds).
2 The autoloader responds as follows:
• The front panel display will show "Force Eject."
• The autoloader waits 35 seconds to give the normal eject procedure a chance to occur.
• Once this time has elapsed, if there is a cartridge loaded in the drive it is immediately
unloaded, regardless of what operation the drive was performing. The cartridge is then
returned to its slot in the magazine, and the drive is reset as though the power had been
cycled.
Because the forced ejection may interrupt any operation, it is possible that the drive will not
write an EOD (End of Data) mark before the cartridge is ejected. This will cause loss of data
and leave the cartridge with an invalid format.
• If no cartridge is loaded in the drive, the autoloader assumes that you want to eject the
magazine. Following the 35-second pause, it does this. The autoloader is then reset as
though power had been cycled.
Note A forced ejection will abort any SCSI operations that may be in progress on the autoloader
and overrides any SCSI PREVENT MEDIA REMOVAL in effect.
