Tape Drive Installation, Replacement, or Removal Instructions Tape drives are installed in drive bays in the back of the Spectra T120 library. This guide provides the instructions for installing, replacing, or removing both half‐height (HH) and full‐height (FH) tape drives. The Spectra T120 library currently supports LTO tape drives. Each tape drive is mounted on a drive sled that provides the electrical and logical connections to the library. Serial Number The drive sled includes intelligence that assigns a serial number to the tape drive based on its location in the library. This location‐based serial number remains constant even if the physical tape drive is replaced. The new tape drive simply retains the designated serial number, so tape drive replacement is completely transparent to the backup software. SCSI ID When you replace a SCSI tape drive in the library with a new SCSI tape drive, the new tape drive assumes the SCSI ID of the old tape drive. WWNN When you replace a Fibre Channel (FC) tape drive in the library with a new FC tape drive, the new tape drive assumes the WWNN of the old tape drive. Partition Follow these partitioning guidelines: Guidelines You cannot mix SCSI, FC, or SAS tape drives in the same partition. You cannot mix LTO‐3, LTO‐4, and LTO‐5 tape drives in the same partition. You can mix HH and FH tape drives if they are the same interface (FC, for example). Fan and Handle In addition to the electrical Full-height SCSI tape drive connections for the tape drive, the drive sled includes a fan to ...

REPARE FOR AINTENANCE Ensuring ESD Protection The repair environment for the library must be free of conditions that could cause electrostatic discharge (ESD). To protect the library from ESD, follow these procedures: Place a static protection mat on the work surface used while removing and installing library components. Use a 1‐megaohm resistor to ground the static protection mat. Wear a static protection wrist band whenever you handle library components that have been removed from their antistatic bags. Connect this wrist band to the static protection mat or to other suitable ESD grounding. Keep all components in antistatic bags when not in use. Determining the Control Path Tape drives can either be direct‐controlled (see Connected to Host (directly connected to another machine) on page 14), or QIP‐controlled (see Connected to QIP on page 14). LTO SCSI or Fibre Channel tape drives can be either direct‐controlled or QIP‐controlled. LTO SAS tape drives must be direct‐controlled (direct attached). Following Backup Guidelines Use your backup software to take the tape drive that you are replacing offline. Restart any backup processes after you complete the installation or replacement. Following Host Power-off Recommendations Spectra Logic recommends that you shut down and power‐off the host before installing or replacing a SCSI tape drive.

Installing a Drive Shelf The library has five permanent shelves installed for the full‐height tape drives. If you are installing or replacing a full‐height tape drive, or installing or replacing a half‐height tape drive on an existing full‐height shelf, skip to Install a New Tape Drive on page 9 or Replace a Tape Drive on page If your installation requires an extra shelf for a new half‐height drive, follow the steps in this section. If you must remove a full‐height tape drive before installing the shelf, see Remove an Existing Tape Drive on page Follow these steps to install the half‐height drive shelf (the shelf). 1. Install the shelf in the location where you want to install the new half‐ height tape drive. Figure 2 Add the new shelf. Tape Drive Installation, Replacement, or Removal Instructions 90950012...

Prepare for Maintenance 2. Lay the shelf horizontally and push it into the library until the shelf will not slide in any further and the protruding tab is fully captured in the slot. Ensure that the tab is captured Figure 3 Align the drive shelf tab. 3. Use a #2 Phillips screwdriver to secure the shelf with the screw that came in the shelf kit. If possible, use a magnetized screwdriver. Tighten screw Figure 4 Secure the drive shelf screw. If you are replacing HH tape drives with FH tape drives, perform these steps in reverse order to remove shelves, as needed. May 2010 Spectra T120 Library...

Improperly adding or removing a device from a SCSI bus can cause the host Caution computer to crash. If you leave the host running during this procedure, Spectra Logic assumes no responsibility for damage to data or equipment. 1. Locate the drive to be installed. Hold the drive sled by the handle and remove it from its anti‐static bag. Set the drive on top of the anti‐static bag until you are ready to install it in the library.

Install the tape drive in the desired location. Connect the interface cables to match your selection in Step 2 (SCSI, FC, or SAS), and terminate the tape drive(s), as needed. See Connect the Cables on page 13 for cabling guidelines. Once the drive is both installed and cabled—see Connect the Cables on page 13—return to the user interface and select OK in the Feedback Required screen.

RIVE Follow the steps in this section to replace a tape drive in the library. If you are replacing a half‐height drive with a full height drive and need to remove a shelf, follow the steps in Installing a Drive Shelf on page 6 in reverse order before proceeding. Remove the cartridge from the tape drive—If you are replacing a malfunctioning tape drive, and it contains a cartridge, attempt to move the cartridge to an empty slot in a magazine. See the Spectra T120 User Guide (Cartridge Use) for instructions. Continue with the replacement even if you are unable to unload the cartridge. Power off the host—Spectra Logic recommends that you shut down and power‐off the host before installing a SCSI tape drive. You do not need to power off the host if you are installing FC or SAS tape drives.e. Improperly adding or removing a device from a SCSI bus can cause the host Caution computer to crash. If you leave the host running during this procedure, Spectra Logic assumes no responsibility for damage to data or equipment.
3. Once the drive is both installed and cabled, return to the user interface and select OK in the confirmation screen. Figure 12 The Replace Drive confirmation screen. Repeat the steps in this section as necessary for each tape drive. ONNECT THE ABLES SCSI Guidelines Restrictions Do not exceed SCSI bus length restrictions. The maximum allowable length of an LVD SCSI bus is 39 feet (12 meters). Performance Connecting multiple devices on a single SCSI bus can impact the performance of all devices on the bus. Daisy-chaining Spectra Logic does not recommend, and does not support, daisy‐chaining other SCSI devices in the same SCSI bus as the drives in the library. Each daisy‐chained tape drive increases the total length of the SCSI bus. A maximum of two LTO‐3 SCSI tape drives can be daisy‐chained together. Spectra Logic does not recommend, and does not support, daisy‐ chaining LTO‐4 or LTO‐5 drives. Do not daisy‐chain FC or SAS drives. Termination Make sure the SCSI bus is properly terminated. You must install a terminator on the device at both physical ends of the SCSI bus. May 2010 Spectra T120 Library...
Cabling Options Connect the tape drive cables using one of the following three options (see Figure 5 on page 8 and Figure 14 on page 15): Connected to Host (directly connected to another machine) You can directly attach all SCSI tape drives, all Fibre Channel tape drives, or all SAS tape drives to a host. Use either port on a Fibre Channel tape drive, or either connector on a SAS tape drive. Connected to QIP You can connect up to four drives directly to one QIP. Additionally, you can daisy‐chain up to two more drives into one (or two) of the QIP attached drives for a maximum of 6 drives. Both LTO‐4 and LTO‐5 tape drives are direct‐attach drives. You cannot daisy‐chain LTO‐4 SCSI tape drives or LTO‐5 tape drives. Connected to Host via Daisy-chaining Whether you have a QIP or direct‐ attached drives, or both, you can daisy‐chain additional LTO‐3 or tape drives (a maximum of two). You cannot daisy‐chain LTO‐4 or LTO‐5 tape drives. SAS configuration Fibre Channel configuration SCSI configuration QIP 2 Not available...

c. Return to the user interface and press OK to continue or Cancel to cancel the action. d. Install the tape drive cover plate using a #2 Phillips screwdriver and the screws that came in the kit. Important Each drive bay must be covered for safety and temperature control. Do not leave any tape drive bays uncovered. If you removed the terminator at the end of the SCSI bus during this process, make sure the SCSI bus is once again properly terminated.
