A video procedure on how to Remove / Replace a Tape Drive in SL500 Library

Solution

DISPATCH INSTRUCTIONS
    - WHAT SKILLS DOES THE ENGINEER NEED:
Knowledge with the SL500 library and LTO tape drives.

    - TIME ESTIMATE: 60 minutes
    - TASK COMPLEXITY: 2

FIELD ENGINEER INSTRUCTIONS:
    - PROBLEM OVERVIEW
Defective drive must be replaced in library.
    - WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
    RESOLUTION ACTIVITY?
Defective drive should be offline to the hardware system and software application.

    - WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
Refer to the SL500 Replaceable Parts Catalog for complete instructions on removal/replacement of a tape drive from the library. This manual provides all Pictures, Notes and Cautions to perform these actions.

NOTE: Refer to the attached Video for assistance on drive replacement.

NOTE: Prior to replacing LTO drive verify the same PN is used. This is to avoid problems with 2 and 4 GB drives being interchanged. HP drives have different code for 2 and 4 GB drives. IBM does not.

Drive Removal:
1. Read the safety and ESD instructions in the "Personal Safety" and "Production Precautions" sections.
2. Be sure the customer has ended all jobs assigned to the drive.
3. Disconnect the Fibre Channel or SCSI cable from the right side of the drive tray.
4. Loosen the spring-loaded screw on the right side of the drive tray until the screw is disengaged.
5. Slide the drive/tray assembly out of the drive bay and set it on a table or cart.
6. If you are removing an LTO2 drive, the drive fan or the PWR/TTI cable, go to step 12, otherwise continue with the next steps.
7. Note the position of the target on the mounted bezel.
8. Gently press the upper right side of the bezel and roll the top right corner of the bezel back slightly to disengage the top right tab from its mount slot.
9. Carefully apply pressure to the lower right side and disengage the bottom tab.
10. Pivot the bezel away from the front of the drive until the mounting tabs on the left side can be easily removed from their slots.
11. If you are only removing the bezel, go to step 13 of the replacement procedure, otherwise continue to the next steps.
12. Remove the 4 T15 Torx screws attaching the cover to the back of the drive tray.
13. Unplug the LC to LC duplex or SCSI cable from the rear of the drive.
14. Remove the cable and cover from the tray.
15. Disconnect the power and TTI cable connectors from the rear of the drive.
16. Inspect the foam and not how it is installed.
17. Turn the drive tray over with the bottom facing up.
18. Remove the 4 T10 Torx screws attaching the tray to the drive and slide the drive off the tray.

Note: For IBM LTO 3 and 4 only: Please verify that the position of dip switch #5 on 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.

Drive Replacement:
1. Flip the tray upright and slide the drive into the tray.
2. Turn the drive and tray over so the bottom is facing up.
3. Align the holes on the bottom of the tray with holes on the bottom of the drive.
4. Attach the tray to the drive with 4 T10 Torx screws.
5. Turn the tray upright and inspect the foam between the fan and RLD card for proper installation.
6. Reposition the foam, if necessary.
7. Connect the power and TTI cable connectors to the back of the drive.
8. Plug the LC to LC duplex or SCSI cable into the back of the drive.
9. Slide the leading edge of the cover behind the side slot in the tray.
10. Press the cover flush with the back of the tray and align the holes.
11. Attach the cover to the tray with 4 T15 Torx screws.
12. If you are replacing an LTO2 drive, the drive fan, or the PWR/TTI cable, go to the caution before step
   17, otherwise continue with the next steps.
13. Orient the taget so that it is positioned at the bottom of the bezel when mounted.
14. Insert the mounting tabs on the left side of the bezel into the 2 mounting slots along the left side of drive
     cartridge opening.
15. Align the bezel's bottom right tab with its mounting slot and gently press the lower right side of the bezel
   until the tab sips into the slot.
16. Carefully press the upper right side of the bezel until the top right tab inserts into the upper mounting slot
   and all the tabs are fully engaged.
17. Slide the drive/tray assembly into the drive bay until it is fully mated with the drive connector and the tab
on the right side is flush against the chassis.
18. Finger-tighten the spring-loaded screw on the right side of the drive tray.
19. Plug the Fire Channel or SCSI cable into the right side of the tray.

NOTE:
Under NO circumstances should tape drives be returned with Media still inside the drive. If a tape is stuck in a drive, review the Knowledge Base or contact Tape Hardware Support for instructions on how to remove the tape with an email to tapehw_ww@oracle.com include the SR/case number in the subject line of the email.

Important Note:

If this is a SDP attached tape drive, it is required to log into the SDP site server to add the newly installed drive serial number or DMOD serial number to complete the drive replacement installation.
Failure to complete this task will result in inaccurate drive health check information.
Refer to the SDP FE User's Guide under "working with Devices" for complete instructions on how to properly make this update.

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO
AN OPERATIONAL STATE:
Have the customer ensure the drive is online to the system hardware and software application and they are able to communicate with the drive.
