Tape Drive Description
Tape Drive Description
Size: The T10000 tape drive is a small, modular, high-performance tape drive
designed for high-capacity storage of data. The drive is:
• Height = 8.89 cm (3.5 in.)
• Width = 14.6 cm (5.75 in.)
• Depth = 42.5 cm (16.75 in.)
Capacity: The T10000 uses a technology called partial response, maximum likelihood
(PRML) to provide the high-density data format that allows the tape drive to
record and store up to:
• T10000A = 500 gigabytes (GB) of uncompressed data.
• T10000B = 1 terabyte (TB) of uncompressed data.
• T10000C = 5 terabytes (TB) of uncompressed data.
• T10000D = 8 terabytes (TB) of uncompressed data.
Media: The new tape cartridge for this drive uses a single-reel hub for high capacity;
the supply reel is inside the cartridge and the take-up reel is inside the tape
drive.
Interface: The host connections to the T10000 are fiber-optic to provide a high rate of data
transfer, such as Fibre Channel and FICON.
Configurations: The T10000 supports two configurations: library and stand-alone,
for a variety of operating system platforms:
• Enterprise mainframes (z/OS and OS/390)
• Open system platforms (Windows, UNIX, and Linux)

This chapter describes how StorageTek tape drives operate using a Fibre Channel
(FC) interface.
Connections
The T10000 tape drives support various connections:
• 2FC = Direct N_Port, Arbitrated Loop, and a Fabric
• 4FC = Direct N_Port, Arbitrated Loop, and a Fabric
• 8FC = Direct N_Port, Arbitrated Loop, and a Fabric
2
Operations
Note – This document is defined by the requirements in FC-Tape
Revision 1.17. As updates occur to the FC-Tape document, this
document will be updated accordingly.
• 16FC = Direct N_Port, and a Fabric
Arbitrated Loop
An arbitrated loop provides multiple connections for devices that share a single loop,
but only provides point-to-point connections between an initiator and target during
communications.
Note – Both public loops and private loops are supported.
As with SCSI protocol, when devices want to communicate on the bus, they must
arbitrate and win the connection before communications can begin. The same goes
with the arbitrated loop. Once a device is powered-on and initialized on the loop, it
must arbitrate and win to be able to communicate with other devices on the loop.
Fabric Attachment
Fabric, or F_Ports, provide “direct” attachments to the tape drives. The Fabric
receives frames from a source N_Port and routes them to a destination N_Port whose
address identifier is specified within the frame.
August 2016 Operations 29
Page 30
Direct N_Port Attachment
Direct N_Port Attachment
The T10000 tape drives support direct attachment to a host through a host bus
adapter (HBA) that creates an N-Port. The HBA sends and receives to and from the
tape drive.
Addressing
StorageTek tape drives use: Port name, Node name, and Port ID for login validation.
The StorageTek registration ID is 24 bits consisting of:
• 00104F (hex)
TABLE 2-1 indicates the Institute of Electrical and Electronics Engineers (IEEE)
registered format for Name Address Authority (NAA), company ID, and vendor
specific identifier for a total of 64 bits.
TABLE 2-1 Addressing Scheme
Most Significant Bit Least Significant Bit
63 60 59 36 35 00
NAA IEEE Company ID Vendor Specific Identifier
“0101” (b) 00 10 4F (hex) (to be assigned)
All ports validate the logins by comparing Port Name, Node Name, and Port ID. All
three identifiers must match or this indicates the configuration has changed and
requires a Logout (LOGO).
Note – A LOGO terminates all open Exchanges between SCSI
initiator and target.

SCSI Features
The following sections describe the SCSI features supported by the tape drives.
Auto Contingent Allegiance
StorageTek tape drives do not support Auto Contingent Allegiance (ACA).
Asynchronous Event Notification
StorageTek tape drives do not support asynchronous event notification (AEN).
Command Linking
StorageTek tape drives do not support Command Linking. The Link and Flag bits of
the Command Descriptor Block must be set to zero.
Status Byte
SCSI Features
The target returns a status byte to the initiator at the completion of each command
during the Status phase unless the command is cleared or interrupted. The tape
drives support five status byte codes:
• Busy
• Check Condition
• Good
• Reservation Conflict
• Task Set Full
August 2016 Operations 31
Page 32
Status Byte
Busy
Busy (08) status occurs when the target:
• Is busy performing another operation
• Cannot accept a command
The normal initiator recovery from a Busy status is to reissue the command.
Check Condition
Check Condition (02) status occurs when any error, unit exception, or abnormal
condition that generates sense data occurs.
Check Condition status occurs when one of the following conditions exist:
• Issuing an invalid command or parameter
• Issuing a motion command to a device that is not ready
• Issuing a write-type command to a file-protected cartridge
• Issuing a forward motion command to a device at the physical end-of-tape
• Issuing a backspace operation to a device at the beginning-of-tape
• Detecting a deferred check condition
• Exceeding the retry operations for an interface error
• Detecting any error condition that prevents successful completion of an operation
Good
Good (00) status indicates that the device successfully completed the command.
Reservation Conflict
Reservation Conflict (18) status is returned whenever a SCSI initiator attempts an
operation that violates another initiator’s Logical Unit Reservation.
Task Set Full
Task Set Full (28) status is returned when the logical unit receives a command and
does not have enough resources to process it.

Overview

Commands
This chapter defines the SCSI-3 commands for the StorageTek T10000 Tape Drive with
a Fibre Channel interface.
StorageTek uses the SCSI-3 command set to transfer commands and data over Fibre
Channel. The following describes how StorageTek implements these SCSI commands:
• A single command may transfer one or more logical blocks of data.
• The target may disconnect from the arbitrated loop to allow activity by other SCSI
devices while a device prepares to transfer data.
• On completion of normal commands (successful or unsuccessful), the target
returns a Status Byte to the initiator. Because most error and exception conditions
cannot be adequately described with a single status byte, a Check Condition status
code indicates that additional information is available in the FCP Response
Information Unit (IU).
• An initiator should never attempt to send a second command to a device until the
command in progress ends. The second command terminates with a Check
Condition status (Command Overrun).

Implementation Requirements
The initiator sends commands to the target using Command Descriptor Blocks
(CDBs). The CDBs contain a format that includes:
• Operation code
• Command parameters
• Control byte
For some commands, a list of parameters accompanies the request during subsequent
FCP_DATA Information Units.
For all commands, if there is an invalid parameter in the Command Descriptor Block,
then the device terminates the command without altering the medium or executing
the command.
Notes:
• The CDB Field in Byte 1, Bits 7-5, which was the LUN Field is now
reserved. The drive will ignore this field.
• RSVD indicates that “bit” is reserved.

• At drive power on.
• When the TapeAlert Log page is read.
• When specified corrective action has been taken (such as using a cleaning
cartridge).
• On a reset.
Note – The entire TapeAlert page should be read to obtain all the

Mode Select Command
The Mode Select command specifies options and parameters for a device. StorageTek
recommends the host system perform a Mode Sense command before each Mode
Select command to determine the current settings and to avoid any unwanted
alterations to other Mode Select fields.
The Mode Sense command determines which fields can be changed by the Mode
Select command and what the default values are for these fields.
The tape drives support both 6- and 10-byte commands.
