Yu,
The piblication that you are using is incorrect. I have cabled and
configured this drive "7 ways to Sunday" and the element numbers are
definately NOT 15 & 16.
The element numbers are 116 and 117.
Yes, you can daisy chain this device from a 7331 (another specialty :-).
However, depending on how you do this, you could be diminishing you
throughput --> even with a Fast/Wide adapter.
Below I have an included, an informal, but quite extensive document on this
device. It is approached from the AIX perspective, but there are ADSM
references where appropriate. Possibly it will be of use to you.
Best Regards,
Jennifer

EVERYTHING YOU WANTED TO KNOW ABOUT THE 7337 BUT WERE AFRAID TO ASK.........
EVERYTHING YOU WANTED TO KNOW ABOUT THE 7337 BUT WERE AFRAID TO ASK.........
WHAT IS A 3447 AND WHY IS IT IMPORTANT?
The 3447 is a single ended attached unit for attachment to Windows NT
hosts. The tape drive port(s) are clearly marked with a yellow tag
that indicates "SCSI <> SE".
The 7337 is a differentially attached unit for attachment to RISC/6000
hosts. The tape drive port (s) are clearly marked with a yellow tag
that indicates "SCSI <> DIFF".
The 7337 and the 3447 are essentially the same drive unit with different
attachment methods.
For this reason, if a customer receives a "new" drive straight out
of the box and the library display shows that it is set to 3447 AND
has single ended ports --> changing the drive type in the Setup Menu
will not be enough (like you can do with a 3570). The customer should
contact their Point of Sale and indicate that they received a model
for Windows NT attachment rather than RISC/6000 attachment.
However, if the unit has differential drives but the display shows
that it is a 3447, simply enter the Set Up menu and access the
"Inquiry" prompt and select 7337. For more information on how
to enter and use the Set Up menu, see : "HOW DO I GET INTO AND USE THE
SETUP MENU?"
WHAT'S THIS KEY FOR?
This tape unit as a key switch that affects the control of the library
door and the robot movement.
Key Set to 3 O'clock:
Front Door Locked
Robotic Enabled
Operator Panel Disabled
Key Set to 9 O'clock":
Front Door Unlocked
Robotics Disabled
Operator Panel Enabled
Key Set to 12 O'clock:
Front Door Locked
Robotics Enabled
Operator Panel Enabled
* Hint: If you can not get the key to turn, release the door slightly
and try again.
WHAT DRIVERS DOES IT USE?
For AIX (OS commands only):
Tape Drive(s) -->
Uses the SCSD driver contained in the devices.scsi.tape package
Robot -->
Uses the Atape Driver. Versions 4.1.0.0 and later
This driver should be shipped with the unit.
For ADSM:
Tape drive and Library are configured via the ADMS devices drivers
available as a part of the ADSM server code. For details on
configuring the drive for ADSM, see previous LIST SERV posting from
Craig Bell of ADSM Development.
HOW DO I CABLE THE SINGLE DRIVE MODEL?
Use the appropriate Adapter to 1st Device SCSI cable from the host
adapter card into one of the Library Controller's (robot) two ports.
The port(s) for the Library Controller are the rightmost pair of ports
when facing the rear of the drive.
Use the appropriate Device to Device SCSI cable from the second port
of the Library Controller into one of the two tape drive ports.
Place a terminator into the second tape drive port.
There is no "In" or "Out" ports. Therefore, you may reverse the above.
EX: host to tape drive port --> tape drive port to Library Controller
--> terminator in the second Library Controller Port.
HOW DO I CABLE THE DUAL DRIVE MODEL?
Use the appropriate Adapter to 1st Device SCSI cable from the host
adapter card into one of the Library Controller's (robot) two ports.
The port(s) for the Library Controller are the rightmost pair of ports
when facing the rear of the drive.
Use the appropriate Device to Device SCSI cable from the second port
of the Library Controller into one of the two tape drive ports of one
of the two tape drives.
Use the appropriate Device to Device SCSI cable from the second port
of the first tape drive to one of the two ports of the second tape
drive.
Place a terminator into the second port of the second tape drive.
There is no "In" or "Out" ports. Therefore, you may alter the above
in any desired fashion to alleviate cable stress provided that the is
a terminator at either the Library Controller or the leftmost tape
drive.
*Note: IBM now offers a SCSI-2 Differential cable with smaller connectors
specifically for this drive.
HOW DO I SET THE SCSI ADDRESSES AND WHAT ARE THE DEFAULTS?
When the 7337 unit is shipped, the default SCSI addresses are as
follows:
Library Controller --> 6
Tape Drive 1 (or drive in single drive unit) --> 4
Tape Drive 2 --> 5
To change the SCSI address defaults,
The Tape Drives may be changed by using the "Push Button" at the rear
of the drive or through the Set Up menu.
The Library Controller may only be changed through the Set Up menu.
For information on how to manipulate the Set Up menu, see
"HOW DO I GET INTO AND USE THE SETUP MENU?".
WHAT ARE THE LIBRARY MODES OF OPERATION?
Automatic (Sequential) --> Used to span autoload tapes.
Use this mode with Sysback/6000
Use this mode to load the next tape
after issuing tctl -f /dev/rmt# offline
*There is NOT an "autoload" option from
the device driver. Therefore, tar, dd
cpio, etc will not span tapes.*
Automatic Loop --> Use this mode with care. This mode will act
in the same manner as Automatic except that
when the last tape in the magazine is ejected,
it will automatically reload the 1st tape in
in the magazine and potentially overwrite data.
Random --> Use this mode with tapeutil of to access the smc device.
The Set Up menu options for this is "AUTOLOAD = OFF"
HOW DO I GET THE smc DEVICE?
The drive must be in Random Mode when the device is configured
in order to get the /dev/smc device.
WHAT IS THE BEST BLOCK SIZE/BUFFER SIZE?
The optimum block size is 262114 (aka 256kbytes). Variable length
of 0 is also useful when coupled with the appropriate buffer
flags.
In order to achieve the best performance, you MUST use the below
buffer flags added to you favorite backup command:
mksysb -b512
savevg -b512
backup -b512
tar -N512
cpio -C512
dd bs=512b OR ibs=512b and obs=512b
bs=256k OR ibs=256k and obs=256k
Sysback/6000 -b256
*For ADSM, to achieve this blocking, add the following to your dsmserv.opt
file:
USELARGETAPEBLOCKS YES
Use this option with care for once you have written tapes using this
option, they MUST be read using this option.
WHAT ARE THE APPLICABLE DENSITY SETTINGS AND WHAT IS DENSITY OVERRIDE?
Where compression is allowed, it is a 2:1 ratio.
Denisty Setting Density Tape Supported Capacity
23 2.6 GB DLT III 2.6GB No Compression
24 6.0 GB DLT III 6.0GB No Compression
25 10.0 GB DLT III 10.0 / 20.0
25 15.0 GB DLT IIxt 15.0 / 30.0
26 20.0 GB DLT IV 20.0 / 40.0
26 35.0 GB DLT IV 35.0 / 75.0
Density Override Off --> Density selected by via Denisty Settings
Density Override On --> Density selected manally
* For ADSM, simply determine your tape capacity and define it appropriately
in the FORMAT paramter of the DEFINE DEVCLASS command.
WHAT IS THE COMPRESSION RATIO?
The compression ratio is 2:1.
(When using hardware compression)

*Note: Do not let the "ABNORMAL" state mislead you. This changes as
tapes are moved. You will see "Abnormal" state when media is loaded
into a slot or drive and "Normal" when it is empty. This will only
occur when the unit does not have the optional bar code reader installed.
For example:
Library has tapes in slots 0 and 1 only.
Slot 0 and 1 will say "Abnormal".
I move the tape from 1 to 5. Now slot 1 will say "Normal" and slot 5
will say "Abnormal".
I then move the tape from 5 back to 1. Now slot 5 will say "Normal"
and slot 1 will say "Abnormal".
The same will occur when media is placed in the drive (116).
However, if you have the optional bar code reader installed, you the
VOLSER number will be displayed rather than "Normal" or "Abnormal".
