DRIVE B DRIVE A SCSI Connectors Figure 6 3.2 Fan DC Fan Power Input Connectors SCSI Connectors 5242-2SE front and rear panels Understanding the Tape Drive LEDs Each 5242-2SE tape drive has a pair of LEDs that indicate drive status. See Figure.
Chapter Three - Controls and Indicators 3.2.2 3.2.3 • Steady green means a tape is loaded. • Fast flashing green means read or write operations are occurring. The Media Caution LED (number 2 in Figure 7) is amber, indicating a fault condition: • Slow flashing amber indicates that the tape drive heads need to be cleaned or the tape cartridge is wearing out. • Steady amber indicates a hard fault. The unit should be replaced. Call the HP Global Customer Support Center.
Chapter Four - Tape Cartridges 4.1 Tape Cartridge A tape 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 are cleaning cartridges and data cartridges. Cleaning cartridges or tapes are used to clean the recording heads of the tape drive with a cleaning ribbon. Data cartridges or data tapes hold magnetic storage media for the tape subsystem.
Chapter Four - Tape Cartridges 4.3 Write-Protecting a Data Cartridge Each data cartridge has a write-protect switch that protects the data cartridge from being overwritten. See Figure 9 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 writeenable the cartridge. Data can then be written to and read from the tape.
Chapter Four - Tape Cartridges Figure 10 4.5.3 Loading a tape cartridge During the load sequence: Tape LED (number 1 in Figure 11) slowly flashes green while the tape is being loaded. The Tape LED becomes a steady green to indicate the tape is loaded. If an excessive number of errors is detected, the Media Caution LED (number 2 in Figure 11) flashes amber. Tape Media Caution 1 2 1 2 Detail A Figure 11 4.
Chapter Four - Tape Cartridges The Eject button is disabled and has no effect when pushed. It does not initiate an unload sequence. A LOAD/UNLOAD command with the LOAD bit set to zero takes the drive off-line and unthreads the tape but does not eject the cartridge. The effects of PREVENT MEDIA REMOVAL continue until an ALLOW MEDIA REMOVAL command is received or the drive is reset. 4.7 Forcing the Ejection of a Cartridge Caution: You might lose data if you force an eject.
Chapter Five - SCSI Bridge Electronics 5.1 Introduction to the 5242-2SE Display At the heart of the display system is the Infourmm SCSI bridge, which provides performance information about the tape operation. In addition to bridging communications between the host and tape drive, Infourmm autonomously sends commands to the tape drive to extract the data necessary for the display.
Chapter Five - SCSI Bridge Electronics 5.4 Display Unit LEDs The display unit has two LEDs, one green and one amber. The green LED indicates that data compression is active. The amber LED is a user-programmable, error-alert indicator that lights when the error-rate percentage reaches a predetermined value. This value can be set or altered using the mode switch in conjunction with the setup menus. 5.
Chapter Five - SCSI Bridge Electronics Figure 15 5.7 Identification of LCD items Performance LCD Format Upon receiving a TEST UNIT READY or INQUIRY SCSI command from the host, the LCD switches to the Performance format which 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. Figure 16 5.7.
Chapter Five - SCSI Bridge Electronics Total data bytes read from or written to the unit appear with a KB (1024), MB (1024 x 1024) or GB (1024 x 1024 x 1024) multiplier. On the first read or write command following a rewind, the count is set to zero. Write E F TOTL XFR 74MB Figure 18 5.7.
Chapter Five - SCSI Bridge Electronics The average compression/decompression ratio appears as the ratio of the compressed and uncompressed data lengths reported by the tape drive. The ratio always appears in the format X.X:X. 5.7.5 Remaining Capacity This value is an estimate of remaining tape capacity. It is computed by multiplying the average compression ratio by the remaining block count. KB, MB, and GB represent multipliers of 1024, 1024 x 1024, and 1024 x 1024 x 1024, respectively.
Chapter Five - SCSI Bridge Electronics When the desired tape density appears, push the mode switch to select it. The selected setting is used until the unit is power cycled or reset. These choices are offered: C0 = Compressed format 40 = Uncompressed format FF = Density controlled by the host software Note: 5.9 The setting from the last change of tape density is used as the default start-up value.
Chapter Five - SCSI Bridge Electronics 5.10.2 Changing a Setting Depending on the menu item, alter settings by using these methods. When the instruction reads PRESS to Alter, you have the option to exit the editing mode to review the settings. Numeric-Entry Method With this method you change settings by entering a decimal or hexadecimal number, digit-by-digit. The LCD shows the instruction PRESS to Incremnt the alterable digit. The highlighted digit is incremented by pressing the mode switch.

Tape Term:On *NOT sel ectable* Figure 31 5.11.4 Tape termination Manually Selecting the Tape Density Tape density format can be controlled by the display unit or by the NonStop server. When the appropriate drivers exist, the latter method is generally preferred, and a setting of FF should be used. Other density values shown allow the SCSI bridge electronics to control the tape density.
Chapter Five - SCSI Bridge Electronics Note: Because the beginning of tape is written to every time a tape is unloaded, this area of the tape tends to wear sooner than the rest of the tape media's length. As a result, it is not unusual to experience rewrites or ECCs at the beginning of tape. If these situations 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.
Chapter Five - SCSI Bridge Electronics 5.12.2 Configuring the options setting If your configuration or host environment requires unique settings or special configurations, HP can provide assistance and firmware configurations for specific platforms, software, or drives through the use of this menu item. This setting is configured at 00001400 and should not be changed by the user.
Chapter Five - SCSI Bridge Electronics 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.
