How to Remove and Replace a Tape Drive in SL8500

Solution

DISPATCH INSTRUCTIONS
WHAT SKILLS DOES THE ENGINEER NEED:
Knowledge of the SL8500 library, STK and OEM Tape drives.

TIME ESTIMATE: 60 minutes

TASK COMPLEXITY: 2

FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW
Need to replace a defective tape drive from the SL8500 library.
- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
RESOLUTION ACTIVITY?
The drive needs to be offline to the hardware system and software application.

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
Look for detailed instructions on how to service the drive tray assembly.

For LTO IBM & HP, SDLT and DLT-S4, refer to SL8500 Service Manual - Section 2 : Removal and Replacement Procedures Tape Drive Components in the SL8500 Documentation Library.

For T10000 Tape Drive, refer to the T10000 Tape Drive Service Manual - Section 3 : StorageTek SL8500 Drive Tray, Tape Drive Removal & Replacement in the StorageTek T10000 Tape Drive Documentation - Internal .

For T9X40 Tape Drive, refer to StorageTek T9X40 Tape Drive Service Reference Manual - Section 6 Removal and Replacement in the StorageTek 9x40 Manuals & Guides - Internal.

Note 1: Maintain the drive tray serial number information in SL8500 or SL3000
SL8500 and SL3000 drive tray serial number gets lost during drive replacement in legacy drive trays(without LOD) Doc ID 2179541.1

Note 2 : Save the configuration settings using the VOP Configure-->Save Drive Config. See Doc ID 2179515.1 for complete instructions.
Note 3 : This only Applies to T10000 and 9840D
Note 4 : Prior to replacing a LTO drive verify the same PN is used. This is to avoid problems with 2 and 4 GB drives being interchanged. HP have different firmware versions for 2 and 4 GB drives
Note 5: For IBM LTO 3 and 4 only: please verify that the position of dip switch #5 at the bottom back of the replacement drive is consistent with the drive being replaced. This specific switch controls the communication method (ADI vs. LDI) for the drive. Improper switch position can cause communication issues in the library.
Note 6 : Under NO circumstances should tape drives be returned with Media still inside the drive. If a tape is stuck in a drive refer to the cartridge recovery procedures in the corresponding Tape Drive Service Manual
      -T10000 : Section 2 Error Recovery of the T10000 Tape Drive Service Manual.
      -T9840 : Section 7 Error and Recovery, T9840 Jammed Cartridge of the T9X40 Tape Drive Service Reference Manual
      -T9940 : Section 7 Error and Recovery, T9940 Tape Malfunctions of the T9X40 Tape Drive Service Reference Manual.

The Action Plan steps listed below apply to T10000, 9840, 9940, LTO (IBM & HP) and SDLT drive tray. Additional details may be called out in the referenced Service Manual documentation for a specific drive type, when applicable.

Drive Tray Removal:
1. Be sure there is no active input/output I/O at the subject drive to/from host and the drive is out of service.
Put drive OFFLINE to SL8500 from SL Console.
2. Open the library rear doors.
3. Disconnect the host interface cable from the tray's rear panel.
4. Depress the power switch. The green LED will flash while the unit is power down. Wait until the LED is solid red before pulling out the drive tray.
5. Press the tray latch lever release tab then rotate the lever upward into the detent position (Unlatched).
6. Pull the tray by the handle straight out of the library drive bay and place it on a suitable work surface.
7. Remove two T10 screws securing the tray top cover and switch guard to the rear panel.
8. Slide the top cover forward and lift it up from the drive tray.
9. Disconnect all cables from tray to drive: Host, TTI, E-net, power, status. Remove 4 T15/T10 screws
securing drive to tray.

Drive tray Reassembly/Re-installation:
1. Position the tray cover and slide toward the rear panel to engage latches.
2. Connect all cables between tray to drive: Host, TTI, E-net, power, status. Insert 4 T15/T10 screws
securing drive to tray.
3. Position switch guard, then insert and tighten two T10 screws into the rear panel to secure the cover.
4. Make sure the tray latch lever is in the upward (detent) position.
5. Slide the drive tray fully into the library drive bay to seat the tray connector.
6. Rotate the tray latch lever downward until it locks.
(Once drive/tray is installed into the library, the drive will automatically power up)
Wait until drive is completely initialized until you plug host interface cable (to allow new dynamic WWN
to be set in drive).
7. Connect host interface cable to the tray interface port.
8. Use SL Console to verify the properties for the drive trays in the replaced drive array.
9. Use SL Console to load a diagnostic cartridge into the replaced drive.
10. Inform the library operator that the replaced drive tray is available.
11. Close the library rear doors.
