Step 2. Checking the Electrical Outlets
Make sure that the electrical outlets that you use are properly grounded.
Step 3. Running the Self Test
Run the self test to determine whether the 7207-122 Tape Drive is functioning
properly. To run the test:
1. If the 7207-122 Tape Drive is installed, remove it by performing steps 1-12
in Chapter 6, “Moving the 7207 Tape Drive” on page 37.
Note: Make sure that the SCSI cable and terminator are not attached to
the 7207-122 Tape Drive (or the self test may not function properly).
2. Set the SCSI address switch to 9 (see “Step 5. Setting the SCSI Address”
on page 6).
3. Attach the power cable to the 7207-122 Tape Drive, then plug it into an
electrical outlet. Make sure that the power to the tape drive is off.
4. Load the SLR5-4GBSL test cartridge into the 7207-122 Tape Drive (see
“Loading Tape Cartridges” on page 14).
Note: Use only the IBM test cartridge, part number 59H3661. Use of any
other test cartridge could cause erroneous test results or lengthen
the time needed to complete the test.
5. Press the 7207-122 Tape Drive power switch to turn on the power.
After approximately 5 minutes, the status light does one of the following:
Flashes green to indicate the completion of a successful self test. Unload the
test cartridge and press the 7207-122 Tape Drive power switch to turn off the
power. Store the test cartridge in a safe location (you may need it for future
diagnostics), then go to step “Step 4. Determining the SCSI Address” on
page 5.
Flashes red to indicate an error. Replace the 7207-122 Tape Drive.
4 7207 Tape Drive Setup, Operator, and Service Guide
Step 4. Determining the SCSI Address
The 7207-122 Tape Drive can only be set to SCSI addresses 0-7. (Addresses 8
and 9 are selectable options, but should not be used in normal operation or errors
will result; address 8 is invalid and address 9 starts the drive self test described in
the preceding step.)
Before you install the 7207-122 Tape Drive, you must find a SCSI address that is
not an address being used by another device. To find an unused SCSI address,
you must:
Identify the name and the port of the RS/6000 SCSI I/O controller that you want
to attach to
Identify the SCSI address of that SCSI I/O controller
Identify the SCSI addresses of other devices connected to that SCSI I/O
controller
Note: If you attach to a wide bus, SCSI addresses 0-15 are available but only 0-7
can be used as an address for this tape unit. Even though the 7207-122
Tape Drive uses only the range of addresses for a narrow bus, it is
designed to not impact the function of the other devices on the wide bus;
they still negotiate a wide attachment and run at appropriate data rates.
1. To identify the name and the port of an RS/6000 SCSI I/O controller that
you want to attach to, at the system prompt type lsdev -C | grep scsi and
press Enter. A list of controllers display in the following format. The names
appear in the first column (for example, scsið and scsi2). The ports appear
in the third column and in the fourth position (highlighted as follows):
Note: Column headings are for reference only; they do not appear on the
screen.
Column 1
Column 2 Column 3 Column 4
scsið Available ðð-ðð-ðS Standard SCSI I/O Controller
scsi2 Available ðð-ð2 SCSI I/O Controller
Note the name and port of the SCSI I/O controller that you want to attach to
(for example, the scsi2 controller on port 2).
2. To determine the SCSI address of the SCSI I/O controller that you noted in
the previous step, type lsattr -El scsix | grep id (where x equals the
last character in the name of the SCSI I/O controller) and press Enter. The
address of the SCSI I/O controller displays in the following format:
id 7 Adapter card SCSI I True
Note the address of the SCSI I/O controller (in this case, 7).
Chapter 2. Setting Up 5
3. To identify the SCSI addresses used by all other devices, type
lsdev -Cs scsi and press Enter. A list of devices appears in the following
format. In the fourth position of the third column, locate all instances of the
port that you chose in step 1 on page 5. (The list may contain multiple
instances of a port. In the following example, for port 2 (identified in step 1
on page 5) there are three instances.) The addresses of the other SCSI
devices appear in the seventh position (highlighted in the example that
follows):
Column 1
hdiskð Available ðð-ðð-ðS-ð,ð 2.ðGB SCSI Disk Drive
hdisk1 Available ðð-ð2-ð1-2,ð 4.5GB 16 Bit SCSI Disk Drive
hdisk2 Available ðð-ð2-ð1-3,ð SCSI Disk Drive
rmtð Available ðð-ð2-ð1-4,ð SCSI 8mm Tape Drive
For the port chosen in step 1 on page 5, note the addresses of the other
SCSI devices attached to the RS/6000 (in this case, for port 2, the
addresses are 2, 3, and 4).
4. Determine an unused SCSI address for the 7207-122 Tape Drive (in this
case, 0 1, 5, or 6, because 7 was used by the SCSI I/O controller and 2, 3,
and 4 are used by other devices).
Column 2 Column 3 Column 4
Step 5. Setting the SCSI Address
The SCSI address is a unique address that identifies the 7207-122 Tape Drive to
your system unit. Use the SCSI address switch to set the SCSI address of the
7207-122 Tape Drive. The switch (.1/ in Figure 3) is located on the rear of the
7207 Tape Drive. Figure 3 also shows the two 68-pin, wide SCSI bus cable
connectors .2/, the cooling fan .3/, and the power cable connector .4/.
Note: Set the device at the highest available address. Do not exceed address 7,
and do not select a SCSI address that is already in use (refer to “Step 4.
Determining the SCSI Address” on page 5).
Figure 3. Rear View of the 7207-122 Tape Drive
To set the SCSI address, press the + or − push button to access the address that
you have previously determined in “Step 4. Determining the SCSI Address” on
page 5.

Figure 6. Example of Attaching Multiple SCSI Devices to the System Unit
Notes:
1. The terminator and the SCSI bus cable can be connected to either the top or
bottom SCSI connector on the 7207-122 Tape Drive.
2. Only one external terminator is required to terminate the SCSI bus. You do not
need to use the terminator shipped with the 7207-122 Tape Drive if you already
have an IBM-approved terminator installed at the end of your SCSI bus.
3. If the 7207-122 Tape Drive is installed at the end of a narrow bus, do not use
the existing narrow terminator. Instead, use the 68-pin terminator that is
supplied with the device-to-device cable.

Copyright IBM Corp. 1998 13
Status Light
The status light .4/ on the 7207-122 Tape Drive can turn two colors:
Green The light is solid when the drive is operating the tape cartridge; it flashes
during the cleaning cycle.
Amber The light is solid when the tape drive experiences a hardware fault
condition that may or may not be recoverable. The drive will not respond
to other commands until the fault is cleared. To clear the fault, turn the
7207-122 Tape Drive off, then on again:
If the amber light is not on, the fault was cleared and the tape drive
can be used again.
Note: Always clean the tape drive after clearing a fault and before
proceeding with further use.
If the amber light is still on and is solid, refer to Chapter 5,
“Performing Service on the 7207 Tape Drive” on page 27.
The light flashes when the cleaning cartridge has expired, or when the
tape runs off the end of the cartridge or breaks. Replace the cleaning
cartridge or the data cartridge. If the light continues to flash with a data
cartridge loaded, there may be a problem with the tape drive. Refer to
Chapter 5, “Performing Service on the 7207 Tape Drive” on page 27.
Loading Tape Cartridges
To load a tape cartridge, do the following. For information about the type of media
to use, refer to Chapter 4, “Using the Media” on page 19.
1. Make sure that the power is on to the 7207-122 Tape Drive (the power-on light
should be on).
2. Press the unload button. The tape drive door opens.
3. Pull the door down so there is sufficient clearance to load the tape cartridge.
4. Grasp the cartridge (.1/ in Figure 9 on page 15) so that the clear, plastic
cover faces up and the cartridge door .2/ is on the right.
Note: See “Setting the Write-Protect Switch” on page 24 to make sure that
the write-protect switch is properly set.
5. Slide the cartridge into the tape load compartment and close the door.
14 7207 Tape Drive Setup, Operator, and Service Guide
Figure 9. Loading a Tape Cartridge into the 7207-122 Tape Drive
After you have loaded the tape cartridge and closed the door, the tape
automatically winds to the beginning.
Attention: Do not attempt to remove a tape cartridge while the tape is in motion.
You could cause an error and potentially damage the tape or the drive.
Retensioning the Tape
A tape cartridge in the 7207-122 Tape Drive works best when its tape is operated
as a streaming tape. If the tape has been used in streaming operations,
retensioning is not necessary. If the tape has been used in many start-and-stop
operations (non-streaming), retension it after approximately every 30 minutes of this
type of operation.
If the power is on to the 7207-122 Tape Drive when you insert a tape cartridge, the
drive immediately retensions the tape. This is the default setting. AIX system
commands may be used to change the default setting. For more information, refer
to your system documentation.
The tape drive becomes ready before the retension pass and will accept
commands from the host. If you send a command to the drive that requires tape
motion during the retension cycle, the command is executed after the retension
cycle is completed.
Chapter 3. Using 15
Unloading Tape Cartridges
To unload a tape cartridge, press the unload button. The 7207-122 Tape Drive door
opens. Pull the door down so there is sufficient clearance to remove the tape
cartridge.
Cleaning the Tape Drive
Clean the 7207-122 Tape Drive:
After every eight hours of tape motion
If using new data cartridges, after every two hours of operation
Note: A new data cartridge is one that has not been fully written one time, or
has not been exercised for the number of passes it takes to write one
time.
Whenever read or write errors occur
If you encounter media errors while operating the tape drive in a humid or
contaminated environment, increase the cleaning frequency. You may clean the
tape drive as often as after every tape load without adverse effects to the drive.
Attention: When cleaning the tape drive, use only the IBM-approved cleaning
cartridge, part number 46G2674. Any other cleaning cartridge may damage the
drive.
If contamination is allowed to accumulate, the drive will have to perform more
rewrites and rereads, which results in slower performance of the system. Also,
contamination can cause data loss, and may be prevented by regularly scheduled
cleaning of the drive.
To clean the 7207-122 Tape Drive:
1. Make sure that the power is on to the 7207-122 Tape Drive (the power-on light
should be on).
2. Press the unload button (.3/ in Figure 8 on page 13). The tape drive door
opens.
3. Pull the door down so there is sufficient clearance to load the cleaning
cartridge.
Attention: Check to see if the white cleaning filament is visible behind the
cartridge door (.2/ in Figure 9 on page 15). If it is not, the cleaning cartridge
has reached the end of its useful life and must be replaced.
4. Grasp the cartridge so that the label faces up and the cartridge door is on the
right.
5. Slide the cartridge into the tape load compartment and close the door.
After you have inserted the cleaning cartridge into the 7207-122 Tape Drive, the
remainder of the cleaning process is automatic and takes approximately 10-12
seconds. During the cleaning operation, the status light flashes green. When the
cleaning is finished, the status light turns off.

Chapter 4. Using the Media
This chapter describes the types of tape cartridges to use with the 7207 Model 122
4GB External SLR5 Quarter-Inch Cartridge Tape Drive. It gives guidelines for their
usage, defines recommended storage and shipping environments, lists data
cartridge compatibility, and describes variables that affect tape cartridge efficiency.
It also tells how to set the write-protect switch.
Types of Tape Cartridges
The 7207-122 Tape Drive is shipped with a media kit that contains the following
cartridges.
Data Cartridge
Use the SLR5-4GB quarter-inch data cartridge to save or restore programs or data.
For a list of compatible data cartridges, see “Data Cartridge Compatibility” on
page 20.

instructions about how to clean the 7207-122 Tape Drive see “Cleaning the Tape
Drive” on page 16.
To order additional cartridges, refer to “Ordering Tape Cartridges” on page 24.
Data Cartridge Usage and Erasure
Do not touch the tape material in the data cartridge. Any substance transferred to
the tape by touching could cause loss of data.
Do not use worn or noisy cartridges. If a cartridge generates frequent read or write
errors, replace the cartridge.
The 7207-122 Tape Drive erases previously used tapes as it overwrites them. The
tape drive overwrites from the beginning of the tape or it can append to the end of
existing data.
Data cartridges that contain the QIC-4GB-DC (and below) format may be bulk
erased. To properly erase a QIC-4GB-DC data cartridge with a bulk eraser device,
the erasure coercivity rating must be 3000 oersted minimum.

Operating and Non-operating Environments
Before using a tape cartridge, let it acclimate to the operating environment for as
long as it has been away from the environment or for 24 hours, whichever is less.
(To determine the appropriate operating environment, see “Specifications” on
page 2.)
Acclimation is necessary for any data cartridge exposed to a different humidity
environment or to temperature changes of 11°C (20°F) or more.
The recommended non-operating environment for SLR5-4GB quarter-inch data
cartridges is shown in Figure 10.

Technical Notes about Using SMIT
Handling Compression
You cannot turn compression on and off in SMIT. The default setting is off, with no
option to turn it on. However, you can make compression available for the
QIC-4GB-DC and QIC-2GB-DC formats by selecting the proper density options.
Density 166 is the default density, and is the QIC-4GB-DC format operating with
data compression on. With 2:1 compression, the cartridge capacity is 8GB and the
data rate is 760000 bits per second. If you select density 38, the QIC-4GB-DC
format writes in uncompressed mode.
Compression is handled in a similar fashion for the QIC-2GB-DC format. If you
select density 162, the format writes with compression on. If you select density 34,
the format writes with compression off.
Restrictions on Block Size
SMIT allows you to select block size. Only certain block size selections are valid for
the 7207-122 Tape Drive. Valid block sizes depend on the format written, which
you control by the density setting. Figure 13 defines the block size restrictions.

Notes:
1. To select the variable block mode, set the block size to 0 (the maximum allowable
variable block size is 32768 bytes).
2. Use of block sizes other than those described above will not cause an error while
using SMIT, but will result in an error when you attempt to write with the 7207-122
Tape Drive.
3. If you attempt a read operation with a block size other than the one written on the
tape cartridge, an illegal length error may result.

Tape Cartridge Efficiency
Tape cartridge efficiency refers to the amount of data that can be stored on a tape
cartridge and the rate at which the data can be read from the tape. The following
variables affect the amount of data that can be stored on a SLR5-4GB quarter-inch
tape cartridge:
Mode of operation (streaming or nonstreaming)
Size of the data file
Number of file marks (empty physical blocks on a tape) per file
Variable postambles and preambles (separators between physical blocks on a
tape)
Type of format (QIC-4GB-DC, QIC-2GB-DC, QIC-1000-DC, QIC-525-DC,
QIC-150-DC, or QIC-120-DC)
