Solution

DISPATCH INSTRUCTIONS
WHAT SKILLS DOES THE ENGINEER NEED:
Trained in Oracle/STK tape drive and knowledge of SL3000 library.

DELIVERY REQUIREMENT:
Schedule time with customer under Service Agreement
TIME ESTIMATE: 120 minutes
TASK COMPLEXITY: 2

FIELD ENGINEER INSTRUCTIONS:
PROBLEM OVERVIEW
Need to replace a defective tape drive from the SL3000 library.

CONFIRM THE FAULT BY CHECKING:
Verify drive failure by reviewing error information from SL Console in the SL3000 library. Run diagnostics to drive in question to verify errors being reported. Visually inspect drive for errors on Op Panel.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?
The drive in question should be offline to the system and software application.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
Refer to the SL3000 Service Manual for complete instructions on removal and replacement of the tape drive.
All Pictures, Notes, and Cautions are detailed in the manual.

Tape Drives and the removal and replacement procedures for LTO drives are provided in chapter 2 of SL3000 Service Manual

Since there are too many exception in replacing the various tape drive models it is essential to read chapter 2 of SL3000 Service Manual for a Field engineer that is not familiar with the tape drive model replacement procedure!!!!

For the replacement details on T1000 tape drive in SL3000 library please read chapter 4 in T1000 Service manual at
T1000 Tape Drive Service Manual
StorageTek T10000 Service Documentation Library

Select manual "Tape Drive Service Manual"

StorageTek SL3000 Drive Tray

Note:

Use VOP to capture the current drive configuration settings and force a diagnostic dump before you power down the drive tray.

Configuration Tasks - see KB 2179515.1

Stay connected to the drive with VOP and force a diagnostic dump on the drive. See the next steps in this process.

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.

'The Action Plan steps listed below apply to T10000, 9840, 9940, and LTO (IBM and HP) drives. Additional details may be called out for a specific drive type, if applicable.'

Drive Tray removal - All Tape Drives:
1. Verify that the drive is offline.
2. Open the rear doors of the module that contains the defective drive.
3. Disconnect the host interface cable.
4 Press the power switch. The green LED will flash while the unit is powering down. Wait until the LED is
   solid red, (approximately one minute), before pulling out the tray.
5. Press the tray latch release lever then rotate the lever upward (into the unlatched position).
6. Firmly holding the tray handle, pull the tray straight out and place the assembly on a suitable work
surface.

Drive Tray replacement - All Tape Drives:
1. Reverse the process described about to complete drive replacement procedure.

Drive Tray removal - LTO Tape Drives:

1. Using a T10 driver, remove the four screws that attach the drive to the sides of the tray.
2. Remove the two T10 screws that attach the top cover plate on the drive tray.
3. Lift up the front of the cover and slide it out of the rear slots on the tray.
4. Pull out the drive part way until-you can feel the cable tension-and remove the drive’s air flow shield.
5. Turn the drive sideways to reveal the cables.
6. Remove first the signal cable connector, then the remaining three connectors
7. Remove the defective drive.

Replacement of LTO4 drive also requires that you:
1. Remove the Bezel from the defective drive and re-install it on the replacement drive.
2. Pay close attention to how the drive is screwed into the drive tray.
3. If the LTO drive is manufactured by HP and contains the encryption feature, an additional circuit card is
    involved. Please refer to the SL3000 manual for the replacement of this card.
4. If the drive is an IBM drive, you must also check the positions of the micro-switches on the bottom of the
drive. These switches set up the drive for library operation. Switches 1 and 2 should be ON and all
    others should be OFF.

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.

To replace an LTO tape drive.
1. For IBM drive, turn over the new drive and verify that the micro-switches are correctly set (1 and 2
should be ON, all others OFF).
2. Insert first the power cable, then the remaining three cables.
3. Carefully slide the drive into the tray.
4. Insert the air flow shield over the drive, being sure that it is located underneath the fan assembly and that
all the cables are covered by the plate.
5. Using a T10 driver, replace the four T10 screws that attach the drive to the tray.
6. Insert the two drive tray cover and replace the two T10 screws.

Important Note:

If this is a SDP2 attached tape drive, it is required to log into the SDP2 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.

SDP2 - How To Add/Update a Drive Serial Number in SDP2 (Doc ID 2039318.1)

Note:
Maintain the drive tray serial number database 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:
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.

NOTE:
Should a tape drive need to be sent back for Failure Analysis as requested by a TSC engineer, please use CPAS process.

OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Bring drive online to the server/host. Verify drive is available for the software application to use.
