You can obtain additional information about the Small Computer System Interface - (SCSI-2 and SCSI-3) by writing or calling: Global - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 27
SCSI Command Overview Library Control Through SCSI Library Control Through SCSI You can control the tape drive and library with the commands described in this document. This SCSI command set complies with ANSI X3.131-198X standards. The role of the following is defined in the SCSI specifications: • - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 28
the target command specifications. The SCSI commands used by the targets are described later in Chapter 2. SCSI Bus Phases The target supports all phases specified in the SCSI standard. This section describes the following phases: • Arbitration • Selection • Reselection • Information Transfer • Data - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 29
together as the information transfer phases because they are all used to transfer data or control information via the data bus. The library only supports asynchronous transfers with a maximum size of 32Kbytes. During all transfer phases that the device writes data to the SCSI bus, odd parity is - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 30
initiator to the target. The target invokes this phase in response to the attention condition created by the initiator. See Table 1-1 for a list of supported messages. Target-Supported Messages Code (Hex) 00H 01H 02H 03H 04H 05H 06H 07H 08H 09H 0CH 80H-FFH Direction In In/Out In In In Out - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 31
SCSI Command Overview Library Control Commands Command Complete 00H, The target sends a message to the initiator to indicate that a command operation is complete (or series of linked commands) and that valid status has been sent to the initiator. After successfully sending this message, the target - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 32

SCSI Command Overview Library Control Commands Save Data Pointer 02H, The target sends this message to the initiator to direct it to save a copy of the present active data pointer for the currently attached logical unit. The target issues this message when it disconnects the SCSI Bus during data - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 35
SCSI Command Overview Library Control Commands When received from an initiator, the tape drive may respond in one of two ways: • It may take the message as a request by the initiator to disconnect and comply by entering the Message In phase and sending the DISCONNECT message back to the initiator ( - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 36
SCSI Command Overview Library Control Commands Message Reject 07, The initiator or target sends this message to indicate that one or more bytes in the last message received was inappropriate or has not been implemented. To indicate that it intends to send this message, the initiator asserts the ATN - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 37
bit is set by the initiator if the target can disconnect/reconnect. • Bit 5: This bit must be set to zero ("Target Routines" not supported). • Bit 4: Reserved. • Bit 3-0: These bits specify a logical unit number. (Only one logical unit number is identified for a selection sequence). Status Phase The - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 38

NOTE SCSI Command Overview Library Control Commands Two queued Unit Attentions are not unusual. For example, if a library is powered up and a cartridge is loaded, Power Up and Not-Ready to Ready Transition Unit attentions are created. If an initiator does not clear Unit Attentions queued for it - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 42
the following: • Retry the operation • Go to the Status phase • Go to Bus Free and prepare Sense Data Other SCSI Functionality • Linked commands are not supported. • Untagged queuing is supported. 1- 18 Chapter 1 - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 43

For example, if the command descriptor bytes sent from the Initiator were 00 00 00 00 04 00, the drive recognizes this as a Test Unit - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 274
Programmer's Tips Performance Tuning Performance Tuning To enhance the overall tape drive performance, use the drive's buffer memory to optimize read and write operations. The buffer memory is for both the write and read-ahead cache. If one is enabled, the entire buffer memory is available for the - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 275
Programmer's Tips Performance Tuning The drive flushes the write buffer to tape under the following conditions: • The write hold-off time limit is exceeded (see MODE SELECT command) • Receipt of the following non-write commands: LOAD-UNLOAD REWIND ERASE LOCATE MOVE MEDIUM PREVENT/ALLOW MEDIUM - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 276
Programmer's Tips Performance Tuning Data Transfer Size The tape drive transfers read and write data to and from the initiator in bursts based on the Maximum Burst Size in the Disconnect-Reconnect Mode Page 02H. This parameter controls how often the drive disconnects, reselecting the initiator - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 277
the initiator's time between polls increases, the bandwidth consumed decreases, yet the average response time increases. The tape drive solves this problem by providing a load completion functionality. 2. Once the tape library returns a GOOD status for the move operation, the initiator should wait - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 278
The host should then re-issue the Read Command to Drive 2. Determining Media Type Loaded The HP digital linear tape drives support the following ISO standard media types. • HP DLTtape IV Data Cartridges • HP DLTtape III XT Data Cartridges The Media Type field in the Mode Select Data Header reports - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 279

If the Read Element Status Command disconnects, it will perform movements identical to that of the Initialize Element Status before sending the element status data. Therefore, the timeout should be set the same as the Initialize Element Status command. - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 287

Programmer's Tips Developing Library Manager Software Moving a Tape Cartridge from a Drive To remove tape cartridges from a drive, the following occurs: 1. Unload the drive and remove the cartridge. 2. When the autochanger is issued a move command where the source is a drive, it automatically - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 291
may require that tape cartridges be cataloged to organize information. The HP digital linear tape libraries have a bar-code reader, which would be able to detect that an element is defective and work around the problem. For instance, if one tape drive was not functioning, the swapping algorithm - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 292
Programmer's Tips Developing Library Manager Software Error Detection The first step in any error recovery is detection. The error codes returned from the SCSI commands allow the autochanger manager software to know if there is a hardware error, restored error, or recovered error. • Hardware errors - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 293
is compatible with the SMART diagnostic standard for disc drives. The host software should first check the tape drive/library to determine whether it supports the TapeAlert Log Sense page 0x2e. By default the host software access to the TapeAlert Log Sense page is via polling. The TapeAlert Log - HP Surestore 28/48-Slot with DLT7000 | Digital Linear Tape SCSI-2 Drive and SCSI - Page 294
tape drive/library is idle. However, the host software may use the TapeAlert Mode page to configure other access methods, depending on what options are supported by the tape drive/library.
