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.

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.

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.

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.

This subsection describes the steps necessary to install the 5242 or 5242-ACL tape drives.
3.2.3.1 Connecting and Routing the AC Power Cord
An AC power cord connects the power supply in the 5242 and 5242-ACL tape drive to the
external power source. To connect an AC power cord to the 5242 and 5242-ACL tape
drives (assumes a non-computer-room installation):
1. Check that the AC power switch on the tape drive is set to the OFF (0) position. This
prevents power from being accidentally supplied to the tape drive.
2. Plug the AC power cord connector into the AC power receptacle at the rear of the tape
drive. See Figures 5 and 6.
3. Plug the other end of the AC power cord into the external power source. For
information about power requirements, see AC Power Requirements on page 8.
4. Move the 5242 or 5242-ACL tape drive into place. Note the service clearance
information under Service Clearance and Dimensions on page 6.
5. Install the 5242 or 5242-ACL tape drive and connect it to the NonStop server.

3.2.3.2 Connecting a SCSI Cable to the Tape Drive FRU
Copper SCSI cables come in lengths ranging from 3 to 25 meters (10 – 82 feet) and do not
require special installation. At the rear of each tape drive FRU, there are two 68-pin SCSI
ports. SCSI cable links. Connect one of these ports to the NonStop S-series server, M8201
Fibre Channel to HVD SCSI router, or S-Series I/O enclosure for use on Integrity NonStop
servers.. A SCSI terminator plugs into the other port. See Figure 9. Connect the SCSI cable
to the SCSI port on the tape drive:
1. Locate the SCSI cable.
2. Align the 68-pin SCSI cable connector, which has thumb screw connectors, with the
uncapped SCSI port on the top as you face the rear of tape drive.
3. Attach the 68-pin SCSI cable connector to the SCSI port and secure the thumb screw
connectors. (See Figure 7.)

3.2.3.5 5242 Tape Drive Power-Up Sequence
When power is applied to the 5242 tape drive, the tape drive performs a series of self-tests to
verify operation. The two LEDs (green and amber) below the drive access slot both turn on
for one second. The amber light then turns off and the green LED flashes for 6 seconds. Both
LEDs turn off when self-test completes. The LCD displays power-on self test for 2 seconds
and then switches to the revision screen.. The tape drive is ready for operation when the
revision screen appears on the front panel LCD. You can load a cartridge at this point by
inserting the cartridge into the tape drive's access slot. If an error message appears during the
power-up sequence, see Troubleshooting the 5242 and 5242-ACL Tape Drives on page 17.

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.

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.
