Library Overview The OCP consists of the following features (see Table 2): Table 2: OCP features Feature ■ OCP Description The OCP displays library status information and allows you to access the library menus. These menus allow you to view or change the library settings, run demonstration programs, or run diagnostic tests. The OCP is discussed in “Using the OCP” on page 60. ■ OCP buttons Use these buttons in combination with the OCP to scroll through screens and select options or commands.
Library Overview Library robotics The library robotics consists of the main components identified in Figure 4. 1 2 1 Picker assembly 2 Vertical motor Figure 4: Library robotics The vertical and horizontal motors move the library robotics into position to pick and place tape cartridges, and rotates the optical scanner 180° to allow the library robotics to pass cartridges between the side storage bins and the back storage bins or tape drives.
Library Overview Although the library does not require tape cartridges to have bar code labels, properly labeled tape cartridges and full storage bins speed up the inventory process and greatly improved media management. Tape drives The ESL E-Series tape library can hold up to 24 Ultrium 460, Ultrium 460-FC, or SDLT 320 tape drives. When fewer than 24 drives are installed in the library, the tape drives must occupy consecutive drive clusters, beginning with drive cluster 0 (see Figure 2 on page 18).
Library Overview Ultrium 460 and 460-FC tape drives The Ultrium tape drive is a high-performance streaming tape drive that uses Linear Tape-Open (LTO) technology. An Ultrium 460 or 460-FC tape drive is capable of storing up to 200 GB (native) of data per cartridge, and has a sustained data transfer rate of 30 MBps (108 GBph) (native). Access the HP StorageWorks Ultrium Tape Drive User’s Guide from http://www.hp.com/support for more information about its features and capabilities.
Library Overview Approved media has the Ultrium format trademark, which indicates the media has passed Ultrium format compliance testing (see Figure 5). Figure 5: HP Ultrium format trademark For best results, always use HP branded media and bar code labels.
Library Overview Caution: Always discard damaged tape cartridges. If a defective tape cartridge is loaded into a tape drive, it may damage the drive, potentially requiring drive replacement. Note: For information on ordering tape cartridges and bar code labels, refer to the ordering sheet that shipped with your library. You can also access this information at http://www.hp.
Library Overview Make it a practice to visually inspect your tape cartridges when loading or removing them from your tape library. Taking a few minutes to check the condition of your cartridges will lower the risk of repeated failures and help ensure uninterrupted backup. Caution: Always discard damaged tape cartridges. If a defective tape cartridge is loaded into a tape drive it may damage the drive, potentially requiring drive replacement.

Library Operations Note: In environments with high potential for static electricity, take additional precautions, such as the use of an antistatic smock or a grounded antistatic mat.
Library Operations Preparing tape cartridges Caution: Handle tape cartridges with care. Do not drop or mishandle them, or place them near sources of electromagnetic interference. Rough handling can damage the cartridge, making it unusable and potentially hazardous to the tape drives. Labeling tape cartridges Caution: The misuse and misunderstanding of bar code technology can result in backup and restore failures.
Library Operations Ultrium bar code labels Ultrium cartridges have a recessed area located on the face of the cartridge next to the write-protect switch. Use this area for attaching the adhesive-backed bar code label (see Figure 17). Do not apply labels onto the cartridge except in this designated area. Caution: The bar code label should be applied as shown in Figure 20, page 53, with the alphanumeric portion facing the hub side of the cartridge.
Library Operations For successful operation of your tape library, place the bar code label entirely within the recessed area, ensuring that no part of the label is outside of it (see Figure 18). Figure 18: Proper Ultrium bar code label placement SDLT bar code labels SDLT cartridges have a front slide slot located on the face of the cartridge next to the write-protect switch (see Figure 19). Inserting the bar code label by sliding it into the slot.
Library Operations Figure 19: Inserting an SDLT bar code label Media label identifiers Be sure to use the proper bar code labels for your drive technology. Table 5 lists the identifier that is found at the end of 7- or 8-character SDLT and Ultrium bar code labels. Caution: To ensure that your bar codes meet HP’s quality standards, always purchase them from an approved supplier and never print bar code labels yourself.
Library Operations Setting the write-protect switch Each tape cartridge has a sliding write-protect switch. This switch determines whether new data can be written to the tape cartridge (write-enabled) or whether data on the tape cartridge is protected from being erased or overwritten (write-protected). Write-protecting Ultrium tape cartridges By moving the switch to the left (Figure 20), the tape cartridge is write-enabled. By moving the switch to the right, the tape cartridge is write-protected.
Library Operations Write-protecting SDLT tape cartridges By moving the switch to the left (Figure 21), the tape cartridge is write-protected (orange indicator is visible). By moving the switch to the right, the tape cartridge is write-enabled (orange indicator is not visible).

Maintenance and Troubleshooting FC interface controller problems Most problems occur during the initial installation of the interface controller. Before proceeding with advanced troubleshooting techniques, verify all connections and review the configuration. LED indicators The LED indicators on the e2400-160 FC and e2400-FC 2G interface controllers are useful for diagnosing various problems: ■ SCSI bus LEDs (e2400-160 FC interface controller only) — indicate SCSI activity.
Maintenance and Troubleshooting See Figure 34 for LED locations and functions on the e2400-FC 2G interface controller. 8 1 2 3 4 7 6 5 FC drive port TD3 LED FC drive port TD2 LED FC drive port TD1 LED FC drive port TD0 LED 4 5 6 7 8 3 2 1 External port FC1 LED External port FC0 LED Ethernet port LED Interface controller LED Figure 34: e2400-FC 2G interface controller illustration Basic troubleshooting Simplify the installation by reducing it to the most basic configuration.
Maintenance and Troubleshooting Verifying SCSI bus configuration Items to check include: ■ Termination — Problems with termination can cause intermittent or hard failures. A SCSI bus must be terminated on both ends. Termination problems are common when both narrow and wide devices are on the same bus. ■ Bus Type — On an LVD SCSI bus, SE and LVD devices can be connected to the same bus. However, if one SE device is detected during power on, communication to all devices converts to SE mode.
Maintenance and Troubleshooting Note: By default, the FC port speed is set to 2 Gb/s. Changes to the FC port speed must be manually set, such as for 1 Gb/s. If set incorrectly and the FC interface controller is plugged into a Loop or Fabric, the unit may receive framing errors, which can be found in the trace logs, and the fiber link light will be off because of the incorrect FC link speed.
Maintenance and Troubleshooting Verifying the host configuration In some cases, the FC HBA or host device driver may not be working properly. Check the configuration of these elements. It may be useful to check the release notes for the device driver to see if there are any specific issues or a required configuration.

Maintenance and Troubleshooting Maintaining tape cartridges Note: In addition to the information provided in this manual, access the HP StorageWorks SDLT Tape Drive Reference Guide, and the HP StorageWorks Ultrium Tape Drive User’s Guide from http://www.hp.com/support for more information. For longer life of recorded or unrecorded tape cartridges: ■ Do not carry cartridges loosely in a container that exposes them to unnecessary physical shock.
Maintenance and Troubleshooting ■ If it doesn't rattle, check the tape leader inside the cartridge. To do this, open the door on the rear of the tape cartridge by releasing the door lock. The tape leader should be visible at the top-left of the tape cartridge. Caution: Do not touch the tape leader or the tape medium. Dust or skin oils can contaminate the tape, impact performance, and cause damage.
Maintenance and Troubleshooting Cleaning tape drives Use the guidelines in the following sections to clean your tape drives. Cleaning SDLT tape drives Be aware of the following: ■ Under normal conditions, the cleaning cartridge is effective for about 20 cleanings. ■ SDLT tape drives typically do not need regular cleaning, as their design allows for minimal head contamination. ■ Use the cleaning tape only if the library indicates that the drive needs cleaning.
Maintenance and Troubleshooting Caution: Only use HP Ultrium Universal Cleaning Cartridges in Ultrium 460 or 460-FC tape drives. ■ If the cleaning cartridge is ejected immediately, then it has expired or is not an Ultrium cleaning cartridge. Discard it and use a new one. To clean the tape heads: 1. Move a cleaning cartridge into the drive using your application software. The tape drive automatically loads the cartridge and cleans the heads. The cleaning cycle can take up to five minutes. 2.

Glossary Glossary This glossary defines terms used in this guide or related to this product and is not a comprehensive glossary of computer terms. Glossary Antistatic mat A mat made of antistatic material which includes a cabled connection to ground at a wall receptacle. ASC The Additional Sense Code is part of the SCSI-2 specification. The additional sense code (ASC) field indicates further information related to the error or exception condition reported in the sense key field.
Glossary Check Condition status Blocks of data are stored on the tape medium along with additional information that the library controller uses to manage storage and retrieval. The format of the additional information is unique and is hidden from the initiator during normal read or write operations. This additional information is often used to identify the physical location of the blocks of data and the address of the logical block, and to provide protection against the loss of the user data.
Glossary Elements SCSI designation for any device or bin in the library that can hold a cartridge. SCSI elements include storage bins, tape drives, load port bins, and the picker. EMI Electro-Magnetic Interference refers to unwanted electrical noise present on a power line. This noise may leak from the power lines and affect equipment that isn't even connected to the power line. Such leakage is called a magnetic field. Magnetic fields are formed when unwanted noise voltages give rise to noise currents.
Glossary NVRAM Non-Volatile Random Access Memory is a type of memory that retains its contents when power is turned off. One type of NVRAM is SRAM that is made non-volatile by connecting it to a constant power source such as a battery. Another type of NVRAM uses EEPROM chips to save its contents when power is turned off. In this case, NVRAM is composed of a combination of SRAM and EEPROM chips. PCI The PCI bus typically runs at speeds of 33 MHz or 66 MHz and is usually 32 bits wide.
Glossary SDLT Super Digital Linear Tape is a Quantum tape drive and tape cartridge specification offered in three ranges of capacity and transfer rates for workgroup, mid-range, and enterprise needs. SNMP Short for Simple Network Management Protocol, a set of protocols for managing complex networks. Take-up leader The ring at the beginning of a tape in a cartridge. Tape drive controllers A device that controls the transfer of data from a host to a tape drive and vice versa.
