Which operating systems are supported?

LTO tape drives can be connected to servers running under Solaris, Linux and other major operating systems. Refer to http://
www.oracle.com for the most recent information about the operating system versions that are supported.
StorageTek LTO Half-Height SAS Tape Drive 7
Page 8

How do I connect the drive to my server?

Installation requires a SAS host controller or host bus adapter (HBA) that supports tape.

Internal drives

The tape drive is installed into a spare drive bay in your server and is attached to the host server's internal SAS controller
or SAS host bus adapter. See also Installing an internal tape drive (page 9).
You need one industry-standard, 5¼-inch, half-height bay in which to install the LTO tape drive. Different models of server
require different mounting methods. Refer to your server documentation for detailed information.

External drives

A SAS cable is required to connect to an external SAS port. If your server does not have an active external SAS port, you
must purchase and install an additional HBA. (Some controllers have an external connector, but its default state is inactive
because the SAS channels are in use for internal disks.) See also Installing an external tape drive (page 15).

Power specifications

For a detailed product specification,please refer tohttp://www.oracle.com/us/products/servers-storage/storage/tape-storage/
index.html.
Table 2 Power specifications

Power requirements,external tape drives

Solaris drivers

Tape drivers are available on My Oracle Support (MOS) (https://support.oracle.com).
LTO-3HH and LTO-4HH SAS tape drives require Solaris 10 Update 5 (05/08) or later.
LTO-6HH and LTO–5HH SAS tape drives require Solaris 10 Update 8 (10/09) or later.

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 configuration, where the tape drive is attached to a standalone server, you can use backup software that
is designed for a single-server environment. Innetworkconfigurations you will needbackup softwarethat supports enterprise
environments.
Further details about suitable products can be found on http://www.oracle.com/us/products/servers-storage/storage/
tape-storage/029151.htm. It is important to check for software compatibility and install any recommended upgrades.

Attach mounting hardware (page 9)
Install drive (page 10)
Connect SAS and power cables (page 11)
Secure the drive (page 13)
Reboot the server (page 13)

Prepare mounting bay

You need one industry-standard, 5¼-inch, half-height bay in which to install the LTO tape drive.
WARNING! To avoid personal injury or damage to the server or tape drive, ensure that the server is disconnected from the
main power supply while you install the drive.
CAUTION: Static electricity can damage electronic components. Wear an antistatic wriststrap if possible. If not, to equalize
the electromagnetic charges, touch a bare metal part of the chassis, such as the backplate. Similarly, touch a bare metal part of
the drive before installing it.
1. Assemble the necessary tools and materials:
Phillips screwdriver
Flat-head screwdriver (if your server uses slotted screws)
Torx screwdriver (if your server uses torx screws)
Your server manuals (for reference during installation)
2. Perform a normal system shutdown and turn off the server and any connected peripherals.
3. Remove the cover and front panel from the server, as detailed in your server's documentation.
As you work inside the server, you may have to disconnect other signal cables or power cables from other devices to
maneuver the new drive into place. If you have to do this, make a note of their position and connections so you can put
them back correctly later.
NOTE: The server must provide forced cooling and be capable of drawing 6 cfm (0.17 m3/minute or 10.08 m3/hour) of
air through the tape drive at up to 40° C ambient operation. This reduces to 4 cfm at 35° C ambient operation. Ensure that
empty bays have the appropriate blank plates installed so that airflow is maintained.
4. Remove the filler panel from a spare 5¼-inch bay of your server, as described in your server's documentation. With some
servers, you must also remove the half-height device divider.
5. You are now ready to install your tape drive.

Attach mounting hardware

If your server requires special rails or other hardware to install the tape drive, mount them on the tape drive now.
If your server does not require special mounting hardware, proceed to Install drive (page 10) now.
Check your server documentation to ascertain the correct method of mounting, and to check whether mounting hardware is
provided with the server or must be purchased separately.
CAUTION: If you remove an existing drive, do not assume the screws that you remove are the correct length for your new
LTO drive. Use washers or shims to tighten, if necessary.
StorageTek LTO Half-Height SAS Tape Drive 9
Page 10
Different models of server require different mounting methods. Always refer to your server documentation for details. The
following diagrams illustrate common mounting methods. If mounting hardware is supplied with your tape drive, it may
not be exactly the same as shown in the illustrations.
Figure 2 Attaching mounting rails

2. M3 offset mounting screws
Figure 3 Attaching locating screws

Install drive

NOTE:
If cable access for the tape drive bay is awkward, it may be easier to access power and other connections if the tape drive is
installed in the top bay. You may need to move other devices to lower bays to achieve this. Refer also to your server
documentation.
Slide the tape drive into the open bay, aligning the tray or rails with the slots in the bay, as shown in (page 11).
10 Installing an internal LTO SAS tape drive
Page 11
Figure 4 Installing tape drive
NOTE: The illustration shows a server that uses mounting rails. If your server does not use mounting hardware, check that
the holes in the chassis are aligned with the holes in the side of the tape drive.
Do not secure the drive at this point because you may have to move the drive to get the cables into place.

Connect SAS and power cables

IMPORTANT:
A SAS HBA and SAS cable are required. The connector on the SAS drive is a SAS plug connector as per SFF–8482.
1. If a SAS HBA is not already installed, follow the instructions supplied with the HBA to install it before you install the tape
drive.
2. Connect the purchasedSAS cable to thenew HBA. Theconnector on the SASdrive is a SASplug connector asper SFF–8482.

M3 screws1
Figure 8 Securing drive, no mounting hardware used
NOTE: If you cannot tighten the screws, use washers to secure them.
2. Ensure blank plates are in place over empty bays and replace the cover on the server.

Reboot the server

Reboot the server to power up the tape drive and server.
Watch the boot screen carefully after installation. If there are any errors or unexpected messages go back and check the SAS
cabling carefully.
Have you installed the correct SAS cable?
Have you reconnected all devices securely?
If this does not resolve the problem, refer to Troubleshooting (page 29) for further guidelines.

3 Installing an external LTO SAS tape drive

If you are installing an internal LTO tape drive, please refer to Installing an internal tape drive (page 9).
In this chapter:
HBAs and cables (page 15)
Connecting the tape drive to an external SAS port (page 15)
Reboot the server (page 16)

HBAs and cables

This chapter describes how to connect your tape drive to an external port on the host controller or new HBA. If the server has
an active external SAS port, a recommended SAS cable is required to connect to it. If the server does not have an active external
port, you must purchase and install an additional HBA that supports external connection to tape and a recommended cable.
NOTE: If you use a recommended cable (not supplied) to attach directly to the external SAS port and the tape drive does
not function, one possible cause is that the port is inactive or not supported for external tape devices. Refer to your server
documentation for further information on supported configurations.

Connecting the tape drive to an external SAS port

1. If installing a new HBA, follow the instructions supplied with the HBA to install it.
2. Connect the purchased SAS cable to the external SAS connector on the new HBA.
1. SAS connector on server (types may vary, mini-SAS SFF-8088 shown)

Reboot the server

Switch on the tape drive and power up the server. The power on/off switch is on the front panel.
Watch the boot screen carefully after installation. If there are any errors or unexpected messages go back and check the SAS
cabling carefully.
If this does not resolve the problem, refer to Troubleshooting (page 29) for further guidelines.

4 Verify installation

Once you have installed the drive hardware, check that drivers have been installed correctly and that you have the correct
version of backup software, and verify that the tape drive is functioning properly before you store your valuable data.
We recommend that you download the latest driver from the My Oracle Support (MOS) website (https://support.oracle.com).
See also Solaris drivers (page 8).
NOTE: Certain backup applications require you to use their own tape driver instead of the Solaris tape driver.
1. Switch on the drive and the server.
2. The tape drive will run its hardware self-test, which takes about 5 seconds. If the self-test passes, the green Ready LED
flashes and then shows steady green. If the test fails, the Drive Error and Tape Error LEDs flash, while the Ready and
Clean LEDs are off. This continues until the drive is reset. See Understanding the LEDs (page 19) for more information
about front panel lights.
3. Verify that the tape drive installation was successful.
4. For all operating systems ensure that you have downloaded any upgrades necessary for your backup application. Check
http://www.oracle.com for software compatibility and install any recommended upgrades.
5. Carry out a backup-and-restore test to check that the drive can write data to tape. Use a blank cartridge.
Native backup applications can be used to check basic tape drive operation, but they will not support all the advanced
features of your tape drive. We recommend that you upgrade your software application before running this test.

Cartridges

Data cartridges

LTO tape drives use Ultrium tape cartridges. These are single-reel cartridges that match your drive's format and are optimized
for high capacity, throughput and reliability. Compatible media can be recognized by the LTO logo, which is the same as the
logo on the front of your drive. Do not use other format cartridges in your tape drive and do not use Ultrium cartridges in
other format tape drives.
For optimum performance always use a data cartridge that matches the specification of your tape drive. A lower specification
will have a lower transfer speed and may not support write activities; a higher specification will not support read or write.

Cleaning cartridges

The recommended cleaning cartridge is the Ultrium Universal Cleaning Cartridge. This cleaning cartridge is designed to
work with any LTO drive. It may be used for up to 50 cleans.
NOTE: Do not use the earlier LTO cartridge (Blue), or LTO cartridges from other manufacturers.

WORM data cartridges

LTO-6, LTO-5, LTO–4 and LTO–3 tape drives include support for both re-writable and Write-Once, Read-Many (WORM)
data cartridges. WORM cartridges provide for an enhanced level of data security against accidental or malicious alteration
of data on the tape cartridge. The WORM data cartridge can beappended to maximize the full capacity of the tape cartridge,
but the user will be unable to erase or overwrite data on the cartridge. Any attempt to modify a WORM cartridge to enable
writing over existing data will result in the media becoming permanently write protected. It should still be readable in a
WORM drive, depending upon the severity of the tampering, but no further appended backups will be possible.
WORM data cartridges are clearly identified by their distinctive, two-tone cartridge color. They can only be used with LTO
tape drives that support the WORM feature.

Write protecting cartridges

WARNING! Always remove the cartridge from the tape drive before you change the write protection.
If you want to protect the data on a cartridge from being altered or overwritten, you can write protect the cartridge.
To write protect a cartridge, push the switch to the right to prevent any data recording on the cartridge. Note the
padlock on the tab that indicates that the cartridge is protected.
To write enable a cartridge, push the switch to the left to allow data recording on the cartridge.
1. Write-protect tab
Figure 15 Write protecting a cartridge
Write protection will not protect your cartridges against magnets. Write protection will not prevent a cartridge being erased
by bulk-erasure or degaussing. Do not bulk erase LTO format cartridges. This will destroy pre-recorded information and
make the cartridge unusable.
26 Use the correct media
Page 27

Cleaning the tape drive

You must use the Ultrium Universal Cleaning Cartridge with LTO tape drives, as other cleaning cartridges will not load and
run.
To clean the tape drive:
LTO tape drives do not require regular cleaning. An Ultrium Universal Cleaning Cartridge should only be used when the
orange Clean LED is flashing.
1. Insert the Ultrium Universal Cleaning Cartridge.
2. The drive will carry out its cleaning cycle and eject the cartridge on completion (which can take up to 5 minutes). During
the cleaning cycle the orange Clean LED will be on solid and the green Ready LED will flash.
Each Ultrium Universal Cleaning Cartridge cleaning cartridge can be used up to 50 times with LTO tape drives. If the
cleaning cartridge is ejected immediately with the Tape LED on, it has expired.

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 inthe drive. The tape loses tension in the power-off state, whichcan lead toproblems, particularly
if the drive has been moved.
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.
Stick labels onto the label area only.
Do not bulk erase (or degauss) LTO format cartridges because this will render them unusable.

Operating and storage environment

To prevent condensation and for long life, the cartridge should only be operated or stored as follows:
Operation: 100° C to 45° C (50° F to 113° F)
Day-to-day storage (in plastic container): 16° C to 32° C (60° F to 90° F)
Non-condensing relative humidity: 10% to 80% (operating), 20% to 60% (non-operating)
Tapes intended for long-term storage should be stored in the plastic containers, at temperatures between 5° C and 25° C (41°
F and 75° F) and 20% to 60% relative humidity.

8 Troubleshooting

In this chapter:
General Procedure (page 29)
Optimizing performance (page 30)
Problems with cartridges (page 31)

General procedure

If a problem occurs, the first step is to try to establish whether the problem lies with the cartridge, the drive, the host computer
and connections, or the way the system is being operated.
Has the system just been installed?
There could be an installation problem:
1. Check through the information in the relevant installation chapter of this guide.
2. Has the system booted? If not, check that all hard disks arecorrectly seated in the hard disk bayand then check the cabling
between the disks and the SAS controller.
3. Has the system booted but the operating system has not seen the tape drive? Check that the drive has power, the READY
light should be illuminated. If it is not, check that the power cable is connected correctly to the tape drive. If READY is
illuminated, check the cabling between the tape drive and the SAS controller.
4. Are appropriate drivers and application software installed on the host?
5. Check the environmental conditions against the specified limits.
Table 6 Environmental specifications for LTO tape drives
Non-condensing humidity rangeTemperature range
Operating
of 6 CFM airflow
Are you using new cartridges or a different brand of cartridge? Have you been using the particular cartridge for a very long
time?
The problem could lie with the cartridge:
1. Check through the media chapter, Use the correct media (page 25).
2. Check that you are using an Ultrium cartridge. Compatible media can be recognized by the LTO logo, which is the same
as the logo on the front of your drive.
3. Use the correct media type, for example:
Ultrium 6.25 TB RW and Ultrium 6.25 TB WORM tape cartridges for use with LTO–6 tape drives.
Ultrium 3 TB RW and Ultrium 3 TB WORM tape cartridges for use with LTO–5 tape drives.
Ultrium 1.6 TB RW and Ultrium 1.6 TB WORM tape cartridges for use with LTO–4 tape drives.
Ultrium 800 GB RW and Ultrium 800 GB WORM tape cartridges for use with LTO–3 tape drives.
4. Has the cartridge been write protected? See Write protecting cartridges (page 26).
5. Clean the tape heads with the cleaning cartridge, see Cleaning cartridges (page 26). Make sure you are using the Ultrium
Universal Cleaning Cartridge.
6. Try the operation again.
7. If the problem still occurs, try using a different cartridge.
8. If the problem is still there, the problem probably lies with the drive or the host computer.
Has the drive been moved recently? Have any cables been disconnected and reconnected? Has the environment
changed—unusually hot, cold, damp or dry? Has there been dust or dirt near the drive. Have reasonable precautions against
static been taken?
20 to 80% RH (non-condensing)50° to 95° F (10° to 40° C) at a minimum
10 to 95% RH (non-condensing)–40° to 151° F (–40° to 66° C)Storage
StorageTek LTO Half-Height SAS Tape Drive 29
Page 30
The problem could lie with the drive:
1. Check the cables and connectors.
2. Clean the tape heads with the cleaning cartridge.
3. If the problem persists, check the environmental conditions against the specified limits, see (page 29). Perhaps move
the drive to a more suitable site.
Has a new operating system been installed in the host computer? Has new backup software been installed?
The problem could lie with the host or the software. Consult the computer's operating manuals, the software manual, or
seek help from a service engineer.

Optimizing performance

Variousfactorscan affect tapedriveperformance, particularly in anetworkenvironment. In nearlyall cases when performance
is not as expected, it is the data rates of the disk subsystem that cause the bottleneck.
If your tape drive is not performing as well as expected—for example, if backup windows are longer than expected—please
consider the following points before contacting Customer Support.

Can your system deliver the required performance?

The LTO–6 tape drive can write uncompressed data at up to at up to 160 MB/sec (576 GB/hour).
The LTO–5 tape drive can write uncompressed data at up to 140 MB/s (504 GB/hour).
The LTO–4 tape drive can write uncompressed data at up to 80 MB/s (288 GB/hour).
The LTO–3 tape drive can write uncompressed data at up to 60 MB/s (216 GB/hour).
To obtain this performance it is essential that your whole system can deliver this performance. In most cases, the backup
application will provide details of the average time taken at the end of the backup.
Typical areas where bottlenecks can occur are:
Disk subsystem
A single-spindle disk will not be able to deliver good data throughput at poor compression ratios. Best practice to
ensure good throughput is to utilize multiple disk spindles or data sources.
System architecture
Be aware of the architecture of your data protection environment.
The aggregation of multiple client sources over a network provides a good way of delivering good performance, but
anything less than Gigabit Ethernet will limit performance for LTO tape drives.
Some enterprise class backup applications can be made to interleave data from multiple sources, such as clients or
disks, to keep the tape drive working at optimum performance.
Tape media type
The data cartridge should match the specification of the tape drive. A lower specification will have a lower transfer
speed (see Data cartridges (page 25)). Use:
Ultrium 6.25 TB R/W or Ultrium 6.25 TB WORM cartridges with LTO–6 tape drives
Ultrium 3 TB R/W or Ultrium 3 TB WORM cartridges with LTO–5 tape drives
Ultrium 1.6 TB R/W or Ultrium 1.6 TB WORM cartridges with LTO–4 tape drives
Ultrium 800 GB R/W or Ultrium 800 GB WORM cartridges with LTO–3 tape drives
Data and file types
The type of data being backed up or restored can affect performance. Typically, small files incur greater overhead in
processing and access than large files. Equally, data that is not compressible will always limit the speed at which the
drive can write/read data. You will achieve no more than native rates with uncompressible data.
30 Troubleshooting
Page 31
Examples of files that compress well are plain text files, spreadsheets; those that compress poorly are either compressed
as part of their format (such as, JPEG photographic files) or stored as compressed (such as, .ZIP files or .gz/.Z files on
Unix platforms).

Problems with cartridges

If you experience any problems using LTO branded cartridges, check:
The cartridge case is intact and that it contains no splits, cracks or damage.
The cartridge has been storedat the correcttemperature and humidity. This prevents condensation. Seethe insert included
with the tape cartridge for storage conditions.
The write-protect switch is fully operational. It should move from side to side with a positive click.

The cartridge is jammed

If the cartridge is jammed or the backup application is unable to eject it, you can force eject the cartridge. If the failure occurs
regularly, contact Customer Support.
1. Either press and hold the Eject button on the front of the tape drive for at least 10 seconds.
2. Wait for the cartridge to be ejected. This process may take up to 10 minutes (the maximum rewind time). It is important
that you allow sufficient time for the drive to complete this process. If you interrupt it, you may damage the media or the
tape drive. The drive is then reset as though you had turned the power off and then on again.
You may lose data if you force eject a cartridge. The tape may also become unreadable because an EOD (End of Data)
mark may not be properly written.
3. If the cartridge is still jammed, the tape drive has failed, contact Customer Support.

The drive will not accept the cartridge (or ejects it immediately)

The cartridge may have been damaged, for example dropped, or the drive may have a fault. If it is a cleaning cartridge, it has
probably expired and should be discarded immediately. For data cartridges:
1. Check that the drive has power (the power cable is properly connected and the Ready LED is on).
2. Check that you are using the correct media. Use only Ultrium media, (see Use the correct media (page 25)).
Ultrium 6.25 TB RW and Ultrium 6.25 TB WORM tape cartridges for use with LTO–6 tape drives.
Ultrium 3 TB RW and Ultrium 3 TB WORM tape cartridges for use with LTO–5 tape drives.
Ultrium 1.6 TB RW and Ultrium 1.6 TB WORM tape cartridges for use with LTO–4 tape drives.
Ultrium 800 GB RW and Ultrium 800 GB WORM tape cartridges for use with LTO–3 tape drives.
3. Make sure that you have loaded the cartridge with the correct orientation (see Loading a cartridge (page 23)).
4. Check for damage to your media and discard it if it is damaged.
5. Use a new or known-good piece of media and see if it loads. If it does, the original cartridge is faulty and should be
discarded.
6. Check if another LTO drive of the same model will accept the cartridge. If it does, the original drive may be faulty. Before
calling customer service, please check that the tape drive is responding.

Encryption troubleshooting

Ensure that you are using an LTO-6, LTO-5 or LTO-4 tape drive and Ultrium 6.25 TB, 3 TB or 1.6 TB media, respectively.
Ensure that your software supports hardware encryption. It may be necessary to update the software. Consult your
software vendor for more information.
Ensure that the correct key or pass phrase has been entered.
Ensure that your HBA supports the encryption commands. It may be necessary to update the firmware.
