Using the Cleaning Cartridge

: To prevent contamination of the subsystem and damage to the heads (1) do not use the cleaning

Note

cartridge for more than the manufacturer's specified number of cleaning cycles; and (2) do not attempt to rewind the material in the cleaning cartridge and reuse it.

 Insert the cleaning cartridge into the drive. The drive automatically takes the cartridge, loads it and

cleans the heads. After about 30 seconds, the drive ejects the cartridge.

: If the cartridge ejects after only about 14 seconds, this means the cartridge has reached the end of its

Note

useful life, and no cleaning has occurred. The Cleaning Needed LED may still be illuminated. If this happens, discard the cartridge and with a new cleaning cartridge, repeat the cleaning operation.

 Take the cartridge out of the drive. Write the date on the label of the cleaning cartridge so that there

is a record of how many times it has been used. Do not use the cleaning cartridge more times than specified by the manufacturer.

Section 1: General Information

General Information

1.1 Introduction

Both the 5242 and 5242-ACL tape drives use helical scan tape technology and offer full read-and-write capability. They come in tabletop configurations that integrate a tape drive, status display, and highperformance SCSI electronics.

With a steel chassis and a sturdy ABS plastic shell, the 5242 and 5242-ACL provide optimal performance in many environments. Place units on top of each other like stereo components or line them up like books on a shelf. The modules interlock securely for stability. With individual power supplies, they are self-contained and independently field replaceable units (FRUs).

1.2 Applications

The 5242 and the 5242-ACL are typically used as backup devices to prevent data loss from human error and hardware failures. They also support other tape applications such as:

• Archive data

• NonStop s-series SIT / SUT distribution

• File inquiry and update

• Distribution and exchange of data and software

1.3 Software Prerequisites

• G06.23 or later versions of OSM are required for HP NonStop S-series servers

• H06.03 or later versions of OSM are required for HP Integrity NonStop servers

• 5242 and 5242-ACL tape drives are supported on G06.10 through G06.22 by installing the G06.23 or later version of OSM and the appropriate software product revisions (SPRs). See prerequisite SPRs for OSM In the OSM Migration Guide for G06.23 or later.

1.4 SCSI Cable

A copper SCSI cable is used to connect the tape drive FRU to a NonStop server. One end of the cable has a 68-pin connector with thumb screws that connect to the uncapped SCSI port at the rear of the tape drive. The other end of the cable also has a 68-pin connector with thumbscrews that connects to the NonStop Sseries differential SCSI port or to the HP M8201fibre channel to M8201 Fibre Channel to HVD SCSI router on Integrity NonStop servers. Connectivity is supported for Integrity NonStop servers via attachment to a NonStop S-series I/O enclosure. Copper SCSI cable lengths can range from 10 feet (3 meters) to 75 feet (23 meters).

: The 5242 and 5242-ACL tape drives do not include a SCSI Cable. HP offers a variety of

Note

SCSI cable lengths . For HP cable information, see section 6.1 on page 28.

Table 2 Tape drive part numbers

1.6 Cartridges

A cartridge is a storage device that contains either magnetic tape or a cleaning ribbon inside a protective case. The cartridge protects the tape or ribbon and makes handling easier. The two types of cartridges: (1) cleaning cartridges and (2) cartridge tapes.

1.6.1. Cleaning Tapes

Cleaning cartridges are used to clean the recording heads of the tape drive with a cleaning ribbon.

1.6.2 Cartridge Tapes

Cartridge tapes hold magnetic storage media for the tape drive. A cartridge tape is a self-contained plastic shell containing a spool of magnetic tape. These cartridges are used to record and read back system data.

1.6.3 Humidity

To avoid condensation problems, allow a tape to stabilize at least two hours after a change in humidity or temperature before using.

1.6.4 Life Expectancy of Tapes

DDS-certified media is electronically checked to withstand at least 2000 passes. Under optimum environmental conditions (50% relative humidity, 22ºC), this is equivalent to about 200 to 300 backup operations. This rating takes into account that an area of tape might have several passes during a backup. Sustained use at the low end of the humidity specification reduces the tape life.

1.6.5 Using Labels

Cartridge and magazine labels must be firmly stuck to the recessed label area and nowhere else. To avoid a mechanism jam:

• Labels must be firmly stuck and not peeling off or curling at the corners.

• Labels must be stuck only within the label area.

• A label must not be stuck on top of another label.

• Only use the labels that are supplied with the cartridges or magazine.

Section 1: General Information

1.6.6 Write-Protecting a Cartridge

The tape cartridge has a write-protect switch that protects data cartridges from being overwritten. To protect the cartridge, slide the switch all the way to the left. The hole will be visible. Data can then be read from the tape but not written to it. Slide the switch to the right (covering the hole) to write-enable the cartridge. Data can be written to and read from the tape.

Figure 3 Write-protecting a cartridge

Caution

: The tape log, which contains a history of usage of the tape, is not updated when

the cartridge is write-protected. The tape log is invalid if a cartridge is used when write-protected.

1.7 Labeled and Unlabeled Tapes

The 5242 and 5242-ACL tape drives can use both labeled and unlabeled cartridge tapes. A tape

label is a record at the beginning of a tape that identifies the tape volume and the files it contains. An expiration date protects labeled-tape information from being accidentally overwritten. A scratch tape is a labeled tape with an expiration data that has passed. If a tape has no standard label, it is considered unlabeled. Nonstop servers support two standard tape-label formats:

 ANSI  IBM-MVS

: Because they can be cataloged and offer security features for protecting data, labeled tapes

Note

should be used with the 5242 and 5242-ACL tape drives.

Chapter Two

2.1 SCSI Compatibility

5242 and 5242-ACL tape drives comply with the American National Standard Institute (ANSI) standard X3.131-1986 (SCSI-1) and the ANSI standard X3T9.2 (SCSI-2). These standards define the specifications for the Small Computer System Interface (SCSI). As defined by the ANSI, SCSI is essentially an input/output bus for interconnecting computers and peripherals.

2.2 DAT72 Format and Compatibility

5242 and 5242ACL DAT72 format is an extension of the DDS-3 format. DDS formats have been developed to provide data storage for computers by using and extending DAT technology. DAT72 allows 36 GB of uncompressed data to be stored on a DAT72 (170m) cartridge. Data compression can increase the cartridges native capacity. A compression ratio of 2:1 raises the capacity of the cartridge to 72 GB.

• The DAT72 format allows compressed data to be stored in a way that maintains the full functionality of the DDS-3 format and ensures backward compatibility in reading and writing with existing 5142 and 5142ACL DDS-3 tape drives.

• The drive automatically decompresses data even if data compression is switched off.

• DDS-3 tapes written on a DAT72 drive are readable on a DDS-3 drive; however, a DAT72 tape (170 meters) is not readable on a DDS-3 drive. A DDS-3 drive (both single drive and ACL models) automatically ejects a DAT72 cartridge. An ACL unit ejects the cartridge into the magazine but does not unload the magazine. Additionally, the ACL displays: TAPE FAULT: TRY NEW TAPE.

• The DAT72 format uses the same error correction techniques as the DDS-3 format. It incorporates the error correction techniques used in DAT drives with additional techniques designed to provide superior data integrity.

Section 1: General Information

The 5242-ACL's power-up sequence includes:

1. The three LEDs blink until the self-test completes (approximately 30 seconds).

2. All segments of the 5242-ACL's autoloader LCD are energized.

3. The SCSI ID of the internal drive electronics displays on the autoloader LCD. This is not the same ID as seen by the NonStop server.

4. The value of the internal drive configuration switches is shown. It should be FF1.

5. A self-test message displays on the 5242-ACL autoloader LCD.

6. The Insert Mag message appears on 5242-ACL autoloader's LCD indicating that the tape drive is ready for operation.

If the magazine is inserted (but not loaded) during the power-up sequence, a message

prompts you to close the door. The drive is ready for operation when the Insert Mag message appears on the autoloader LCD. Load a cartridge by inserting it into the slot until the loader takes it in automatically. If an error message appears during the power-up sequence, see Troubleshooting the 5242 and 5242-ACL Tape Drives on page 17.

3.2.3.7 Checking and Setting the SCSI ID

The SCSI ID identifies the tape drive to the NonStop server. To display the SCSI ID, use the mode button and main LCD on the tape drive front panel. Tape drives attached to a NonStop server use a SCSI ID of 5 (daisy-chained drives use IDs 5 and 4). Tape drives always shipped with a SCSI ID of 5. Check the SCSI ID during installation, or after tape drive replacement.

The SCSI ID of a tape drive is stored in nonvolatile RAM. You can check or set the SCSI ID using the mode button and main LCD on the tape drive front panel. Power must be cycled to the tape drive to check or set the SCSI ID. The procedure is the same for both the 5242 and 5242-ACL. Familiarize yourself with the 5242 and 5242-ACL front-panel controls before beginning this procedure and review Sections 2 and 3.

Table 9 Troubleshooting the 5242ACL Tape Drive

3.3 Configuring the 5242 and 5242-ACL for NonStop servers

This subsection describes how to configure the 5242 and 5242-ACL tape drive to a processor multifunction (PMF) or IOMF:

• The group, module and slot hierarchy

• Identifying FRUs

• Completing the PMF or IOMF Configuration Form

• Configuring the 5242 and 5242-ACL tape drive online using SCF

Integrity NonStop servers are also covered in this section. They are configured in a similar manner except for the addition of some extra syntax specific to the Integrity server.

3.3.1 The Group, Module and Slot Hierarchy

Components in a NonStop S-series server are organized according to a group, module, and slot

hierarchy:

3.3.1.1 Group

A group consists of all objects accessible to a pair of service processors (SPs) in a system enclosure. A NonStop S-series group contains one enclosure with a single module.

3.3.1.2 Module

A module is a set of components sharing a common hardware interconnection, such as a backplane. A module is a subset of a group, and it is usually contained in a system enclosure. A module contains one or more slots. In a NonStop S-series server, there is one module in a group.

HP StorageWorks DAT 72 (Models 5242 and 5242-ACL) User's Guide 17 HP Part Number 528296-03 July 2005

Page 25

Section 1: General Information

3.3.1.3 Slot

A slot is a labeled physical space in an enclosure into which a FRU is installed. FRUs are replaced by HP certified service providers.

3.3.2 Identifying FRUs

FRUs in NonStop S-series servers are identified by their physical location. To locate an FRU, you need to know:

3.3.2.1 Group Number

The group number identifies all objects connected through the service processors (SPs)

located on the processor multifunction (PMF). For NonStop S-series servers, this includes everything in a system enclosure.

3.3.2.2 Module Number

For Nonstop S-series servers, there is only one module in a group, so the module number is

always 1.

3.3.2.3 Slot Number

The slot number identifies a position within a module. The slot number is indicated by a label beneath the slot.

Group and slot labels help you locate I/O controllers that need service. Some software might show

the location using abbreviations for group, module, and slot. For example, the Subsystem Control Facility (SCF) storage subsystem might display the location of a PMF or IOMF as:

PMF.GRP-1.SLOT-50

For more information on system organization, group numbering, or labeling for a NonStop S-series

server, refer to the Nonstop S-Series Planning and Configuration Guide.

3.3.3 Completing the PMF Configuration Form

If you plan to connect a tape drive to a PMF or IOMF, document the configuration using a

Configuration Form. This form documents configurable entities associated with the connector. It also provides information about the tape drive to be connected.

: Ensure the IOMF or PMF is terminated on the NonStop S-series server.

Note

3.3.3.1 Enter the product number of the tape drive in the Product Number field. Allowable product numbers are 5242 and 5242ACL.

HP StorageWorks DAT 72 (Models 5242 and 5242-ACL) User's Guide 18 HP Part Number 528296-03 July 2005

Page 26

Section 1: General Information

3.3.3.2 Enter the Subsystem Control Facility (SCF) name of the tape drive in the SCF name field.

3.3.3.3 Enter the product number of the SCSI cable you plan to use with this tape drive in the SCSI cable field. You must use one of the SCSI cables listed on page 1.

3.3.4 Configuring the 5242 and 5242-ACL Tape Drive Online Using SCF

Use the Subsystem Control Facility (SCF) to configure tape drives for NonStop servers. SCF allows

you to add, change the attributes of, and delete a tape drive. You can run SCF from any terminal on the system after you are logged on. Using SCF, you can:

• Obtain configuration information about a tape drive

• Restore access to a tape drive

• Stop access to a tape drive if there is no activity

• List tape drive status

• Switch the primary processor for a tape drive

: Use the product code 5242 when configuring the 5242 tape drive or 5242-ACL when

Note

configuring a 5242-ACL tape drive.

For information about how to use SCF to configure, control, and inquire about all supported tape

drives for Nonstop S-series servers, see the SCF Reference Manual for G-Series RVUs.

Example 1: Defining and Adding a Tape Drive

Use the SCF ADD TAPE command to define and add a 5242 or 5242-ACL tape drive to the

NonStop server configuration.

Before using the ADD TAPE command, check that the tape drive is installed properly. For

installation instructions, refer to page 5. Verify the group enclosure, module, and slot to which the tape drive it is connected.

The first example below adds a 5242 tape drive, $TAPE0. to a NonStop S-series system. The second

example adds a 5242 tape drive, $TAPE0, to an Integrity NonStop server system configuration:

->&PRIMARYCPU 0, BACKUPCPU 1, PRODUCT 5242

>ADD TAPE $TAPE0, SENDTO STORAGE, LOCATION (2, 1, 55),&

->ADD TAPE $TAPE1, SENDTO STORAGE, LOCATION (110, 3, 2),LUN0, SAC2, PORTNAME WWN OF DEVICE TO BE

->&PRIMARYCPU 2, BACKUPCPU 3, PRODUCT 5242

CONNECTED

In this example:

• The LOCATION attribute specifies the location (group, module, slot) of the PMF or IOMF

adapter to which the tape drive is attached.

• The PRIMARYCPU attribute specifies the processor in which the primary tape process should

execute.

• The BACKUPCPU attribute specifies the processor in which the tape process starts its backup

process.

• The PRODUCT attribute specifies the product number that identifies the model of the tape

drive.

HP StorageWorks DAT 72 (Models 5242 and 5242-ACL) User's Guide 19 HP Part Number 528296-03 July 2005

Page 27

Section 1: General Information

For the Integrity NonStop server:

 The LUN attribute specifies the logical unit address of the target. LUNs 0 to 15 are valid.  The SAC attribute specifies the deck on the adapter.  The PORTNAME attribute specifies the worldwide name address of the tape target (WWN OF

THE DEVICE TO BE CONNECTED).

For NonStop servers, issue the SCF INFO TAPE command after the ADD TAPE command is

finished to verify that the tape drive has been properly configured. For example:

->INFO TAPE $TAPE0, DETAIL

STORAGE – Detailed Info TAPE configuration $TAPE0

For NonStop servers, the ADD TAPE command adds a 5242 tape drive connected to the PMF CRU in group 02, module 1 and slot 50 to the system configuration using the name $TAPE1:

->&PRIMARYCPU 2, BACKUPCPU 3, PRODUCT 5242

>ADD TAPE $TAPE1, SENDTO STORAGE, LOCATION (2, 1, 50)),&

The syntax is slightly different for Integrity NonStop servers:

->&PRIMARYCPU 2, BACKUPCPU 3, PRODUCT 5242

>ADD TAPE $TAPE1, SENDTO STORAGE, LOCATION (110, 3, 2),LUN0, SAC2, PORTNAME wwn of device to be connected

For more information on the ADD and INFO commands, see the SCF Reference Manual for the

Storage Subsystem.

Example 2: Changing the Values of Tape Drive Attributes

Use the SCF ALTER TAPE command to change the attribute values for a tape drive attached to

your system. The ALTER command changes only the attributes that are specified in the command. Other attributes remain as they were before you issued the command.

This example of the ALTER command changes the value of the compression attribute for the 5242

or 5242-ACL tape drive $TAPE0 to OFF and then issues the SCF INFO command to check the change has taken place:

>ALTER TAPE $TAPE0, COMPRESSION OFF >INFO TAPE $TAPE0

5242ACL Tape Drive Subsystem

Chapter One

1.1 Introduction

The 5242-ACL is a 4mm tape backup device. The 5242-ACL offers high-capacity, on-line tape storage, outstanding performance, and trouble-free operations. It combines a changer mechanism, a DAT 72 tape drive, data compression, and a SCSI interface. The LCD on the front panel of the 5242-ACL provides a clear and comprehensive status report of the tape drives activities.

The 5242-ACL houses up to six DAT 72 cartridges In a removable magazine and enables backup of up to 432GB of data, assuming a 2:1 compression ratio. The 5242-ACL supports sequential access mode with minimum interruption time between cartridges.

1.1.1 The 5242-ACL tape drive includes:

• Tape drive with 6-cartridge magazine

• Self test diagnostics

Chapter Two

2.1 Mode of Operation

When a cartridge ejects from the 5242-ACL drive following a host UNLOAD command, the autoloader automatically loads the next available cartridge in the magazine into the drive.

2.2 Terminology

Unloaded A cartridge unloads when it moves from the drive and is placed in the magazine. In this

state, the drive is off-line, and the host cannot perform any operation that would cause tape motion (write, read, space commands). The NonStop server can issue the LOAD command to put the tape drive on-line. Additionally, the NonStop server can execute any diagnostic command that does not access the tape.

Semi-Loaded A cartridge semi-loads when the cartridge is in the tape drive mechanism, but the tape is

not threaded around the head. The tape drive is off-line in this state.

Loaded The tape loads at the end of the load sequence. Then the tape drive is on-line and can

execute all commands, including those that set configurations or run diagnostic tests.

Figure 31 Inserting a magazine

2.4.2.2 Apply steady pressure until the mechanism takes the magazine and pulls it into the autoloader. The autoloader then checks which magazine slots contain cartridges.

2.4.2.3 When the magazine check is complete, the tape drive loads the first available cartridge.

2.4.2.4 The tape drive now performs a load sequence:

HP StorageWorks DAT 72 (Models 5242 and 5242-ACL) User's Guide 35 HP Part Number 528296-03 July 2005

Page 43

Section 3: HP 5242-ACL Tape Drive

1. The tape drive mechanism threads the tape and checks the tape's format (DAT72,

DDS-3, blank, cleaning). If the tape is blank, the tape drive leaves the tape at BOM and waits for the next command.

2. Write and read tests are performed. If the error rate is high, the Operator Attention

LED lights and an error message appears on the LCD. The tape drive then reads the tape log.

3. The drive rewinds and goes on-line, awaiting a command from the NonStop server.

The load procedure takes a maximum of 25 seconds from the time the cartridge loads to the time the tape drive is ready to start acting on the next command from the NonStop server.

2.4.3 Once online, the tape drive sends a CHECK CONDITION on receipt of the next SCSI command from the NonStop server.

2.5 Ejecting the Magazine and Cartridges

2.5.1 A cartridge ejects from the 5242-ACL's autoloader when you press the Eject Button.

2.51.1 The tape rewinds to BOP.

Note: If the tape is write-enabled, the copy of the tape log held in RAM writes back to tape.

2.5.1.2 The tape rewinds to BOM and unthreads.

2.5.1.3 The changer places the cartridge in the magazine.

2.5.1.4 The magazine ejects.

2.5.2 If the NonStop server sends a SCSI LOAD or UNLOAD command with the LOAD bit set as 0, the same procedure is followed but the magazine is not ejected at the end.

Note: If the NonStop server has previously sent a PREVENT MEDIA REMOVAL command,

the unloading action is different in two ways:

1 The Eject Button is disabled and has no effect. It does not initiate an unload

sequence.

2 An UNLOAD command puts the tape drive into a semi loaded state. The drive is

offline and unthreads the tape, but does not eject it.

The effects of PREVENT MEDIA REMOVAL continue until an ALLOW MEDIA REMOVAL command is received or the drive is reset.

2.6 Forcing a Tape to Eject

Caution

If you press the Eject Button when the drive is busy, it may be a long time before the

: You can lose data if you force eject a tape. Also, the tape may end up invalidly formatted,

because EOD may not have been written. Force an eject only as a last resort to recover a cartridge. Never use it as a quick way of ejecting the cartridge

drive responds to the request, because it will first finish the task it is performing. This ensures that the task terminates in a controlled manner, and no data is lost.

Page 44

Section 3: HP 5242-ACL Tape Drive

Note: If the you urgently need to unload a cartridge, even at the risk of losing data, you

must force an eject.

2.6.1 Hold the Eject Button down for at least 5 seconds. The autoloader's LCD displays Force Eject.

2.6.2 The autoloader waits 35 seconds to give the normal eject procedure a chance to occur.

2.6.3 Once this time elapses and a tape is loaded in the tape drive, the tape immediately unthreads and the cartridge ejects, regardless of what operation the tape drive was performing. The cartridge is then placed in its slot in the magazine, and the tape drive resets as though the power had been cycled.

Because the force eject might interrupt operation, the tape drive might not write EOD before the

cartridge ejects. This situation causes loss of data, and results in a cartridge with an invalid format.

2.6.4 If no cartridge is loaded in the tape drive, the autoloader waits 35 seconds, then begins the process of ejecting the magazine. The autoloader resets as though power had been cycled.

4.1 Upgrading the Tape Drive Firmware

The autoloader allows you to upgrade its firmware by inserting a firmware upgrade tape. The process takes at least 3 minutes to complete. To upgrade the firmware by a tape load:

Caution

: Do not disconnect power to the autoloader at any time during the upgrade to avoid

corrupting the firmware in the autoloader.

1. Check that the tape drive is not engaged in any SCSI activity. The Tape Activity LED is off. It is recommended that you first take the unit off-line and unplug the SCSI cable from the tape drive.

2. Place the firmware upgrade tape into magazine slot 1. Insert the magazine into the autoloader.

3. About halfway through the upgrade process, the tape drive automatically ejects the cartridge and the changer mechanism replaces it in the magazine. The magazine ejects.

4. When the LCD shows the message New FW!!!!, the firmware has been successfully upgraded. Remove the firmware upgrade tape and replace it in its box.

The capacity bar graph display updates dynamically during read and write operations. Beginning with the native capacity of the cartridge (125m = 12.0 GB, 170m = 36.0 GB), as reported by the tape drive after a cartridge is loaded. The SCSI bridge electronics applies the current average compression ratio (if any), computes the then current maximum capacity, and displays the bar graph by incrementing or decrementing the appropriate number of vertical bars between the empty icon and the full icon. There are thirty vertical bars, each equating to approximately 3.33% of total capacity.

2.1 Introduction

The SCSI bridge electronics are at the heart of the display system that provides performance information about the tape operation. In addition to bridging communications between the host and tape drive, the electronics autonomously send commands to the tape drive to extract the data necessary for the display. A high-performance processor and dual SCSI buses allow the unit to appear to the host as a tape device on the host bus, and to interface with the tape drive as a new host on the tape bus. This private tape bus can operate independently of a host to provide such capabilities as code-tape generation, code-tape loading and off-line

drive testing. Other features of the SCSI bridge electronics include software configuration retained in nonvolatile memory, flash memory for firmware upgrade, and low semiconductor parts count for reliability.

2.2 Initial LCD

After applying power to the tape drive, the SCSI bridge electronics attempt to access the drive at the selected tape ID. Typically, tape drives require a few seconds to perform their self-test before they respond. The tape drive is not selectable to the NonStop server during this period. If the tape ID has not been correctly selected the tape drive will not complete its power-up sequence and remains inaccessible to the NonStop server. The tape ID is set at the factory and is NOT user-selectable. If the tape drive fails to complete its power-up sequence, contact the HP GCSC.

When the drive is accessed, the LCD presents the tape drive model identification and firmware level on the top two lines, and the SCSI bridge electronics' product name, firmware level and host SCSI ID on the bottom two lines. The tape drive is now selectable by the NonStop server at the host SCSI ID.

2.3 Performance LCD Format

Upon receiving a TEST UNIT READY or INQUIRY SCSI command from the host, the LCD switches to the performance format. This is the main operational format of the LCD. The top two lines of the LCD always display the current SCSI command and the tape-capacity bar graph. The bottom two lines of the display alternate between five performance/status items.

heads. When this buffer is empty, 1 MB of data or more can appear to be instantly written to the tape drive and a correspondingly high transfer rate is displayed on the LCD. When the buffer is sufficiently full, the recording heads are set in motion.

A substantial delay accompanies the first write operation to tape. This results in a drop in

the transfer rate. With continued writing to the tape drive, the tape constantly moves and the average transfer rate approaches the quoted streaming rate.

This value is an estimate of remaining tape capacity that is computed by multiplying the average

compression ratio by the remaining block count, which was obtained from the tape drive. KB, MB and GB represent multipliers of 1024, 1024 x 1024, and 1024 x 1024 x 1024, respectively.

2.3.6 ECC/Rewrite Percentage

The number of ECC (when reading) or rewrite (when writing) occurrences, as a percentage of the

total number of read or write commands since the last rewind, appear in the format XX.X. In general, error rates are the highest at the beginning of a tape because this part of the tape is written to every time the tape unloads. When this area becomes worn, tapes become unreliable. Errors above

10.0 suggest worn tapes or the need to clean the recording heads.

2.6.5 Setting the Error-Alert (ECC/Rewrite Percentages) Thresholds

The SCSI bridge electronics allow you to set numeric percentage for error-alert thresholds that, when exceeded, cause the amber LED (the lower LED on the tape drive front panel) to flash. Enter thresholds by the Numeric Entry method. The rewrite threshold value is set first, followed by the ECC threshold value. Entries take the form XX.X so you can enter values in the range of 00.0 percent to 99.9 percent. (It is recommended setting this threshold to a value of 10.0 percent.) Lower values cause the amber LED to light to flash at a lower percentage of error occurrences.

: Because the beginning of tape is written to every time a tape is unloaded, this area of the

Note

tape tends to wear sooner than the rest of the tape. As a result, it is not unusual to experience rewrites or ECC's at the beginning of tape. If these occur, the predetermined thresholds can be exceeded early, but the percentage then drops below the threshold as reading or writing moves further down the tape. To signal this, the error-alert LED flashes when the error rates exceed the set values but returns to a steady illumination if, once exceeded, the error rate falls below the set value.

Four different baud rates are available for connecting to a serial terminal or terminal emulator: No parity, 8 data bits, 1 stop bit, and xon/xoff flow control. The 3-pin serial connector on the tape drive can connect to a PC serial port by using a communication package such as PRO-COMM (with xon/xoff enabled) to upgrade the flash firmware. Use the Pick Entry Method to select a baud rate.

Pressing the mode switch at this menu item invokes the drive self-test and offers a series of options from which you can select. This standalone exerciser can be used to diagnose problems within the tape drive. Modes of operation include fixed/variable block transfers, spacing, differing densities/compression modes, and a means to control the running time. Records are written with interspersed filemarks, rewound and read/verified. This cycle repeats for other densities supported by the tape drive. During the testing process, you can observe the error rate. If after you use a new tape and clean the heads, a high error rate persists, you might have a tape drive problem. Other errors might display the KEY/ASC/ASCQ bytes of a Request Sense command that are described in your tape drive product manual.

Figure 70 Loading a code tape

The SCSI bridge electronics firmware can be upgraded by using a Code Load Tape. You are

prompted to insert the tape. Do not disturb the unit's power until the end of the procedure. The SCSI bridge electronics relocate some internal firmware, switch to the Performance Display format, read 64Kb, and verifies the tape, rewinds the tape, rereads the 64Kb, programs the firmware and, unloads the tape when complete. You are not be returned to the menu system because this utility alters the RAM/ROM in a non recoverable manner. A cold reset executes.

: For this procedure, it is recommended that you take the tape drive off-line and disconnect

Note

the SCSI cable from the rear connector of the tape drive.
