Introduction: Dell PowerVault 110T DLT VS160 Tape Drive User's Guide

Every time you turn on or reset the drive, it conducts a Power-On Self -Test (POST). This test ensures that the drive is working
properly and is ready to use. While POST is in progress, watch the front panel LEDs to see the progress and results of the test.
During POST, the following actions take place:

The LEDs illuminate one at a time, from left to right, starting with the Ready LED, next the Fault LED, and finally the Clean
LED, at approximately one second intervals
About four seconds later, the Media LED illuminates
Each LED signals a different part of the POST process
All LEDs then turn off momentarily
If a cartridge is not loaded, the Ready LED illuminates and POST is complete, the entire process taking approximately eight
seconds
If a cartridge is loaded, the Ready LED flashes while the drive mounts the cartridge, a process that can take several
minutes depending upon the position of the media in the tape path
As POST completes, the drive makes a slight buzzing noise for several seconds. This noise is normal and should be
ignored

The drive is now ready to use.

Indicator Activity During Normal Operation - Ready LED

When the PowerVault 110T DLT VS160 Tape drive is in use, the Ready LED indicates the three states detailed in Table 1. The
Ready LED operates independently of the other three LEDs.

Table 1. Ready LED activity and drive status

Ready LED
Activity Drive Status

Off No power to the drive
On Power is on; no cartridge loaded or a loaded cartridge is idle with

no tape motion

Blinking The drive is loading a cartridge or a loaded cartridge has tape

motion indicating read, write, seek, rewind, calibration, or other
cartridge activity

Indicator Activity During Normal Operation - Fault/Clean/Media LEDs

The Fault, Clean, and Media LEDs indicate the status of the drive. Note that the LEDs can indicate more than one of the indicated
operating conditions simultaneously. For example:

If cleaning is required while a DLT1 format cartridge is loaded, both the Clean and Media LEDs are on
If an internal write/read diagnostic fails as a result of a permanent write error, both the Fault and Clean LEDs blink slowly.

Table 2 describes what each front panel indicator means.

Write/Read Diagnostic Mode

NOTICE: This mode overwrites all data on the cartridge in the drive. Use extreme caution when using this
feature to avoid loss of important data.

When you release the button, the drive initiates an internal write/read diagnostic. The diagnostic requires that you first load a
cartridge that is blank or does not contain valuable data. When the diagnostic begins, the drive writes and then reads approximately
400MB of data and then unloads and ejects the cartridge. The process takes about two minutes. If the diagnostic test detects no
errors, the drive returns to normal operating mode. If an error occurs, the appropriate LEDs illuminate.

Dell-Installed Drives

Dell™ performs the installation and setup of tape drives that are shipped as part of a system. Dell also installs tape backup drivers
and most software applications.

Installing the PowerVault 110T DLT VS160 Tape Internal Drive

SCSI Requirements

The Dell PowerVault™ 110T DLT VS160 Tape Internal drive incorporates a wide -ultra 160 Low-Voltage Differential (LVD) SCSI
bus, but may also be attached to a Single - Ended (SE) SCSI bus.

Make sure your SCSI host adapter or controller supports these standards. If you connect the drive to an SE SCSI bus or if there
are SE devices attached to the same SCSI bus, the drive's performance is limited to the maximum data transfer speed and
maximum cable lengths of the SE bus. The PowerVault 110T DLT VS160 Tape is not compatible with a standard differential (Diff)
or High-Voltage Differential (HVD) SCSI bus. If you attach the drive to a narrow (50- pin) SCSI bus, you must use a customer­supplied 68 -pin to 50 -pin adapter that terminates the unused 18 pins. These adapters are sometimes labeled "high-byte
termination."

Make sure the total length of the SCSI bus does not exceed the ANSI SCSI standard of 19 feet (6 meters) for an SE bus, 40 feet
(12 meters) for an LVD SCSI bus with multiple devices, or 82 feet (25 meters) for an LVD SCSI bus with a single device.

Unpacking the Internal Drive

NOTE: If the room in which you are working differs from the temperature in which the tape drive was shipped or stored
by 30 degrees F (15 degrees C) or more, let the drive acclimate to the surrounding environment for at least 12 hours
before operating.

Unpack and inspect the PowerVault 110T DLT VS160 Tape Internal drive for shipping damage. If you notice any damage, report it
to both Dell and the shipping company immediately.

Getting Started and Setup: Dell PowerVault 110T DLT VS160 Tape Drive User's Guide

NOTE: Save the packing materials in case you need to move or ship your drive in the future. You must ship the
PowerVault 110T DLT VS160 Tape Internal drive in the original or equivalent packing materials or your warranty may be
invalidated.

Setting the SCSI ID

Regardless of the number of SCSI devices attached to the server that is to be the host for the PowerVault 110T DLT VS160 Tape
Internal drive, each must have a unique SCSI ID. Check the SCSI IDs on all other SCSI devices on the selected server, including
the SCSI host adapter, and select an unused SCSI ID for the PowerVault 110T DLT VS160 Tape Internal drive. The factory default
SCSI ID is 6. If another device is not already using the factory default SCSI ID, you do not need to change the drive's SCSI ID.

NOTE: If you attach the drive to a narrow (50- pin) bus, you can only use SCSI IDs 0 through 7.

Locate the SCSI ID jumpers on the rear panel of the drive as shown in Figure 1.

Figure 1. SCSI ID jumpers on rear panel of drive

To set the SCSI ID on the PowerVault 110T DLT VS160 Tape Internal drive, use the supplied jumpers to select the desired SCSI
ID as shown in

Table 1 . After you change the SCSI ID, restart the host server to activate the new SCSI ID and to allow the server

to recognize the drive at the new ID.

Getting Started and Setup: Dell PowerVault 110T DLT VS160 Tape Drive User's Guide

When to Use Termination

If the PowerVault 110T DLT VS160 Tape Internal drive is the only SCSI device on the selected server other than the SCSI host
adapter, or it is the last physical device on the SCSI bus (at the end of the SCSI cable), it must be terminated. If another SCSI
device is the last device on the SCSI bus, confirm that it is properly terminated and do not terminate the PowerVault 110T DLT
VS160 Tape drive. Regardless of which device is used to terminate the SCSI bus, it must have power applied and be turned on for
proper termination to occur.

To terminate the PowerVault 110T DLT VS160 Tape Internal drive, install an active Low-Voltage Differential/Single-Ended
(LVD/SE) cable -end or inline terminator on the SCSI cable you intend to use with the PowerVault 110T DLT VS160 Tape Internal
drive. See the terminator's instructions for more information.

Terminator Power

At least one device on the SCSI bus must supply terminator power (TERMPWR). The factory default for the PowerVault 110T DLT
VS160 Tape Internal drive is TERMPWR enabled, which is the recommended setting. It is acceptable for more than one device on
the SCSI bus to provide TERMPWR. If you need to disable TERMPWR, remove the terminator power jumper shown in

Figure 1 .

Installing the PowerVault 110T DLT VS160 Tape Internal Drive

1. Shut down the operating system and turn off the selected server. Turn off all attached accessory devices, such as printers
and other SCSI devices. Remove the power cables from the host server and all attached accessories. Failure to follow these
instructions may result in damage to the PowerVault 110T DLT VS160 Tape Internal drive or other devices.

CAUTION: Do not move on to step 2 until you have shut down the operating system and turned off the server
that is to be the host for the PowerVault 110T DLT VS160 Tape Internal drive. Turn off all attached accessory
devices, such as printers and other SCSI devices. Remove the power cables from the host server and all

Requirements

Microsoft® Windows® 2000
PowerVault 110T DLT1, PowerVault 110T DLT VS80, or PowerVault 110T DLT VS160 Tape drive

Before Installing the Diagnostic Package

1. Make sure the tape drive is powered on and that the SCSI bus is in an idle state (stop and/or hold all backup applications).

2. Print these instructions. In the event the server needs to be restarted, you can resume where you left off.

Installing the Diagnostic Package

1. Decide where on the server you plan to install the PowerVault Tools application and related files. You can place the
application on your desktop, in an existing folder, or you can create a new folder for this purpose. Note that when the
application runs, it creates a log file, which also resides in the designated folder. As a result, you should not run the
application directly from the CD as this prevents the application from creating the log file. The log file is useful for Technical
Support in the event that troubleshooting the drive becomes necessary.

2. Insert the Dell PowerVault 110T DLT VS160 Tape Drive User's Manual and Drivers CD into the CD drive.

3. Open the folder d:\Diags on the Dell PowerVault 110T DLT VS160 Tape Drive User's Manual and Drivers CD, where d: is
the drive letter of the CD drive.

4. Drag or copy the PowerVault Tools application to the location chosen in step 1.

5. Browse to the folder chosen in step 1 and double -click the PowerVault Tools icon to run the diagnostic application. You
can run the diagnostic application at any time by double-clicking the PowerVault Tools icon.

6. From the folder d:\Diags on the Dell PowerVault 110T DLT VS160 Tape Drive User's Manual and Drivers CD, where d: is
the drive letter of the CD drive, view the README file for usage instructions, explanation of options, and troubleshooting
guidelines for the PowerVault Tools application. You may want to copy this README file to the location chosen in step 1 for
future use.

NOTE: The front panel controls and indicators are in the same locations on both the internal and external drives. The
internal drive does not have a Power LED.

Indicator Activity During Power-On Self-Test (POST)

Every time you turn on or reset the drive, it conducts a Power-On Self -Test (POST). This test ensures that the drive is working
properly and is ready to use. While POST is in progress, watch the front panel LEDs to see the progress and results of the test.
During POST, the following actions take place:

The LEDs illuminate one at a time, from left to right, starting with the Ready LED, next the Fault LED, and finally the Clean
LED, at approximately one second intervals
About four seconds later, the Media LED illuminates
Each LED signals a different part of the POST process
All LEDs then turn off momentarily
If a cartridge is not loaded, the Ready LED illuminates and POST is complete, the entire process taking approximately eight
seconds
If a cartridge is loaded, the Ready LED flashes while the drive mounts the cartridge, a process that can take several
minutes depending upon the position of the media in the tape path
As POST completes, the drive makes a slight buzzing noise for several seconds. This noise is normal and should be
ignored

The drive is now ready to use.

Unload/Eject Button Feature Description

Normal Unload/Eject

When you release the button, the drive unloads and ejects the cartridge.

Write/Read Diagnostic Mode

NOTICE: This mode overwrites all data on the cartridge in the drive. Use extreme caution when using this
feature to avoid loss of important data.

When you release the button, the drive initiates an internal write/read diagnostic. The diagnostic requires that you first load a
cartridge that is blank or does not contain valuable data. When the diagnostic begins, the drive writes and then reads approximately
400MB of data and then unloads and ejects the cartridge. The process takes about two minutes. If the diagnostic test detects no
errors, the drive returns to normal operating mode. If an error occurs, the appropriate LEDs illuminate.

Emergency Reset

When you release the button, the drive performs a hard reset, behaving as if it had been turned off and then on. A standard POST
then takes place.

Revert to Normal Operating Mode

When you release the button, the drive returns to normal operation.

Loading a Tape Cartridge

The PowerVault 110T DLT VS160 Tape drive reads and writes DLTtape VS1 cartridges. The PowerVault 110T DLT VS160 Tape
drive can read - but not write - DLTtape™ IV cartridges written using the DLT1/VS80 format.

NOTE: The PowerVault 110T DLT VS160 Tape drive automatically ejects any other cartridge types and any cartridges
whose format it cannot read. Make sure all cartridges that you want to use for writing are DLTtape VS1 cartridges.

Loading a cartridge into the PowerVault 110T DLT VS160 Tape drive is fast and easy. After the drive completes POST, insert the

file:///C|/Users/rishi_sood/Desktop/Temp/MissingDocsPosted/110t_dlt/UG/usage.htm[3/8/2013 11:46:13 AM]

DLTtape VS1 cartridge into the cartridge slot, oriented as shown in Figure 2, and push the cartridge gently into the drive until it

stops.

Figure 2. Loading a tape cartridge

The Ready LED blinks while the drive loads the cartridge. When the cartridge is ready to use, the Ready LED is steadily
illuminated. If the cartridge is a DLTtape™IV written using the DLT1/VS80 format, the Media LED is also steadily illuminated.

Unloading a Tape Cartridge

NOTICE: Do not remove a tape cartridge while the Ready LED is blinking.

NOTICE: Remove the cartridge from the PowerVault 110T DLT VS160 Tape drive before turning off the external
drive or the host server for an internal drive. Leaving a cartridge in the drive when power is off can result in
cartridge and drive damage. When you remove the cartridge from the drive, return the cartridge to its storage
case to prolong cartridge life.

To eject a cartridge from the PowerVault 110T DLT VS160 Tape drive, follow these steps:

1. Press the Unload button or use your backup software to eject the cartridge. The Ready LED blinks while the drive rewinds
the tape.

4. Return the cartridge to its storage case to prolong cartridge life.

Setting the Write-Protect Switch on Tape Cartridges

All Tape cartridges have a write- protect switch to prevent accidental erasure of data. Before loading a tape cartridge into the
PowerVault 110T DLT VS160 Tape drive, make sure the write -protect switch on the front of the cartridge is positioned as desired.

Figure 4. DLTtape VS1 cartridge write-protect switch

file:///C|/Users/rishi_sood/Desktop/Temp/MissingDocsPosted/110t_dlt/UG/usage.htm[3/8/2013 11:46:13 AM]

Using the Tape Drive: Dell PowerVault 110T DLT VS160 Tape Drive User's Guide

Slide the switch to the right to write- protect the cartridge. The "locked" icon appears on the switch indicating that the cartridge is
write- protected. Slide the switch to the left to allow the PowerVault 110T DLT VS160 Tape drive to write data to the cartridge. The
"unlocked" icon appears on the switch. The indicator on the top of the cartridge also points to the appropriate icon, indicating the
write- protect status of the cartridge.

Caring for Tape Cartridges

To ensure the longest possible life for all of your tape cartridges, follow these guidelines:

Do not drop or strike a cartridge. Excessive shock can displace the tape leader, making the cartridge unusable and possibly
damaging the PowerVault 110T DLT VS160 Tape drive.
Store tape cartridges in their storage cases.
Do not expose tape cartridges to direct sunlight or sources of heat, including portable heaters and heating ducts.
The operating temperature range for tape cartridges is 50° F to 104° F (10° C to 40° C). The storage temperature range is
60° F to 90° F (16° C to 32° C).
If a tape cartridge has been exposed to temperatures outside the ranges specified above, stabilize the cartridge at room
temperature for the same amount of time it was exposed to extreme temperatures, up to 24 hours.
Store tape cartridges in a dust- free environment in which relative humidity is always between 20% and 80%
(noncondensing). The ideal storage relative humidity is 40%, ± 20%.
Do not place tape cartridges near sources of electromagnetic energy or strong magnetic fields, such as computer monitors,
electric motors, speakers, or X - ray equipment. Exposure to electromagnetic energy or magnetic fields can destroy data on
cartridges.
Place identification labels only in the slide-in slot on the front of the cartridge.
Never use any type of adhesive labels on tape cartridges.

Cleaning the Tape Mechanism

When the Clean LED is on, the PowerVault 110T DLT VS160 Tape drive's read/write head needs to be cleaned. See

Troubleshooting the Drive in Troubleshooting for other conditions that may indicate drive cleaning is necessary.

blinks.

NOTICE: Use only Dell approved cleaning cartridges in the PowerVault 110T DLT VS160 Tape drive. See

Recommended Tapes in Specifications for a list of approved cleaning cartridges. Use of any other type of

cleaning cartridge could damage the read/write head in your drive. If you attempt to load any other type of
cleaning cartridge, the PowerVault 110T DLT VS160 Tape drive prevents damage by ejecting the cartridge after
approximately 25 seconds without allowing the cleaning tape to come into contact with the read/write head.

The host server
does not
recognize the
drive.

The drive's SCSI ID might not be
unique.

Regardless of the number of SCSI devices attached to the server that
is to be the host for the PowerVault 110T DLT VS160 Tape Internal
drive, each must have a unique SCSI ID. Check the SCSI IDs on all
other SCSI devices on the selected server, including the SCSI host
adapter, and select an unused SCSI ID for the PowerVault 110T DLT
VS160 Tape Internal drive.

NOTE: If you attach the drive to a narrow (50- pin) bus, you can

only use SCSI IDs 0 through 7.

The SCSI host adapter might be
incorrectly configured.

Check the SCSI host adapter configuration. Refer to the SCSI host
adapter manuals for instructions.

Troubleshooting: Dell PowerVault 110T DLT VS160 Tape Drive User's Guide

2. Make sure an active LVD/SE terminator is in place on the SCSI

ribbon cable for the internal drive.

The SCSI bus might be improperly
terminated.

The SCSI terminator might not be
at the end of the SCSI bus or more
than two terminators might be
present on the SCSI bus.

The SCSI host adapter might be in
a defective expansion slot.

1. If the PowerVault 110T DLT VS160 Tape drive is the last or
only device on the SCSI bus, make sure the drive is properly
terminated.

2. If the PowerVault 110T DLT VS160 Tape drive is not the last or
only device on the SCSI bus, check all SCSI cable connections
and make sure the last device on the SCSI bus is terminated.

3. Make sure termination is set properly on the SCSI host adapter.

4. If you attach the drive to a narrow (50 -pin) SCSI bus, you must
use a customer-supplied 68 -pin to 50-pin adapter that
terminates the unused 18 pins. These adapters are sometimes
labeled "high - byte termination."

5. Regardless of which device is used to terminate the SCSI bus,
it must have power applied and be turned on for proper
termination to occur.

Make sure the terminators are placed only at each end of the SCSI
bus — normally one at the host adapter and one on the last device on
the bus. However, if both internal and external devices are attached to
the same SCSI host adapter, the adapter may be positioned in the
middle of the SCSI bus and should not be terminated. In that case,
the SCSI devices on each end of the bus must be terminated.

Move the SCSI host adapter to a different expansion slot.

There are fatal or
nonfatal errors for
which you cannot
find the cause.

The SCSI bus might be too long. Make sure the total length of the SCSI bus does not exceed the ANSI

SCSI standard of 19 feet (6 meters) for a Single - Ended (SE) bus, 40
feet (12 meters) for a Low-Voltage Differential (LVD) SCSI bus with
multiple devices, or 82 feet (25 meters) for an LVD SCSI bus with a
single device. If you attach the drive to an SE bus or if there are any
SE devices attached to the bus, the bus is limited to the maximum
cable lengths of an SE bus.

The SCSI bus might be improperly
terminated.

1. If the PowerVault 110T DLT VS160 Tape drive is the last or
only device on the SCSI bus, make sure the drive is properly
terminated. Make sure only the last device is terminated.

2. If the PowerVault 110T DLT VS160 Tape drive is not the last or
only device on the SCSI bus, check all SCSI cable connections
and make sure the last device on the SCSI bus is terminated.

3. Make sure termination is set properly on the SCSI host adapter.

4. If you attach the drive to a narrow (50 -pin) SCSI bus, you must
use a customer-supplied 68 -pin to 50-pin adapter that
terminates the unused 18 pins. These adapters are sometimes
labeled "high - byte termination."

5. Regardless of which device is used to terminate the SCSI bus,
it must have power applied and be turned on for proper
termination to occur.

The AC power source may not be
properly grounded (PowerVault

Cartridge or drive problem. 1. Make sure that the cartridge is write-enabled. Move the write-

protect switch to the write- enabled position. See

Setting the
Write-Protect Switch on Tape Cartridges in Using the Tape
Drive for detailed instructions.

2. If you are attempting to write data, make sure you are using a
DLTtape VS1 cartridge.

3. Make sure that the cartridge has not been exposed to harsh
environmental or electrical conditions and is not physically
damaged in any way.

4. Many backup applications do not read or write to cartridges that
were created using a different backup application. In this case,
you may have to perform an erase, format, or label operation
on the cartridge using your backup application.

5. Make sure you understand any data protection or overwrite
protection schemes that your backup application may be using,
any of which could prevent you from writing to a given cartridge.

6. Retry the operation with a different, known-good cartridge.

7. Clean the tape drive. See

Cleaning the Tape Mechanism in

Network, cartridge, SCSI bus,
backup data set, or backup
application problem.

1. Check the network bandwidth from the host server. If you are
backing up data over a network, compare to a local-only
backup for relative backup speed indication.

2. Make sure that the drive is on its own SCSI bus and not daisy­chained to another tape drive or to the hard drive being backed
up.

3. Clean the tape drive. See

Cleaning the Tape Mechanism in

Using the Tape Drive for detailed instructions.

4. Try a new cartridge. A marginal cartridge can cause
performance problems due to bad spots on the tape requiring
retries.

5. Make sure that the data is being compressed. See your backup
application user documentation for details.

6. Check the size of the files in the backup set. Small file size can
impact performance.

7. Confirm that the backup application is using block sizes of at
least 32KB, and preferably 64KB. See your backup application
user documentation for details.

The drive does
not eject a
cartridge.

Timing or drive problem. 1. Allow sufficient time for the drive to complete any operations,

such as POST, reset, load, unload, rewind, etc. Worst case is
when powering up or resetting the drive with the tape
positioned at the physical end of the media. Recovery from this
state could take several minutes.

2. Allow sufficient time for the backup application to release any
hold it may have on the drive. Worst case could be several
minutes. Confirm that the backup application is not set to
prevent media removal.

3. Try a software eject, using your backup application, allowing
sufficient time for the command to execute.

4. If the drive still does not eject the cartridge, power down the
drive and remove all connectors except power from the rear of
the tape drive. Apply power to the drive and allow it to complete
POST. Press the Unload/Eject button, allowing sufficient time
for the command to execute. See

The drive
repeatedly rejects
a cartridge.

Cartridge or drive problem. The PowerVault 110T DLT VS160 Tape Drive rejects any unsupported

cartridge, such as a DLTtape™ III, an SDLT cartridge, an incompatible
cleaning cartridge, damaged media, a DLTtape™ IV cartridge that is
either blank or was written using an unsupported format such as
DLT4000, DLT7000 or DLT8000, as well as any cartridge that causes
an unsuccessful buckle operation. Inspect the cartridge and confirm
format, type, and integrity. If repeatable with a known - good cartridge,
try cleaning the drive. If cleaning does not help, replace the drive or
call Technical Support.

If the Drive Becomes Unresponsive

On rare occasions, the drive may become unresponsive. If this should happen, use this procedure to reset the drive and unload
the cartridge:

1. Press and hold the Unload/Eject button for approximately 27 seconds until all four LEDs are steadily illuminated (not
blinking).

2. Release the Unload/Eject button while all four LEDs are steadily illuminated. The drive initiates a device reset, then
performs a POST. See
LED activity.

3. Upon completion of POST, press and release the Unload/Eject button as soon as the Ready LED begins to blink and/or you
hear tape motion. The drive attempts to eject the cartridge as soon as the device reset is complete and the drive completes
a mid-tape load. This may take several minutes, depending on the where the media is positioned in the tape path.

4. If you do not press the Unload/Eject button again as indicated in Step 3, the cartridge in the drive is ready to use after the
drive resets and loads the cartridge.
