Familiar with C4 Tape Library

- TIME ESTIMATE: 60 minutes

- TASK COMPLEXITY: 0

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
- PROBLEM OVERVIEW:
Tape drive inside C4 Library is defective and requires replacement.

- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
RESOLUTION ACTIVITY?:
Stop all work to C4 library and tape drives. Offline the library and drives from Operating System and Software Application. Power off the library and drives.

- WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:
Refer to the C4/Quantum PX500 Service Manual for complete instruction on replacing the Tape Drive. Module.

Replacing the tape drive consists of the following steps:
• Turning Off Drive Power
• Removing the Faulty Tape Drive
• Installing the New Tape Drive
• Replacing the SCSI Sub-Plate

There are two ways to turn of the tape drive power, using the operator control panel (OCP) or using the remote management GUI. Refer to the following sections:
• Turning Off Drive Power Using the OCP
• Turning Off Drive Power Using the GUI

Turning Off Drive Power Using the OCP
To turn off tape drive power using the OCP:
1. Press Ops from the OCP Home screen.
    The Operations screen displays (see figure 107).
2. From the Ops screen, use the up and down arrows to highlight Drive Operations and press Enter.
    The Drive Operations screen displays (see figure 108):
3. Use the up and down arrows to select the tape drive to be replaced and press Enter.
4. User the up and down arrows to select power off and press Enter.
    The tape drive powers down.

Turning Off Drive Power Using the GUI
To turn off drive power using the remote management GUI:
1. On the host computer, open the internet browser software.
2. In the Address field, type http://IPaddress/ where IP address is the IP address for the Quantum PX500
    Series library.
3. Enter the username and password and click OK.

Note: The default username and password is admin.

4. Click the Operations tab from the top of the Overview page.
    The Operations page displays.
5. To access the Drives page, from the Operations page, click on the Drives tab at the top of the page.
    The Drives page displays (see figure 110).
6. Enter the drive number of the failed tape drive in the Drive edit box and select shutdown from the
    Action drop down list.
7. Click Apply.

Caution:
If auto-unload is disabled, move any cartridges in a tape drive to another element before power the drive off.

To remove the faulty tape drive:
1. Use a flat blade screwdriver to loosen the two thumbscrews on the SCSI sub-plate (see figure 111).
2. Pull the SCSI sub-plate thumbscrews to disconnect the SCSI sub-plate from the drive (see figure 111).

Note:
This disconnects the SCSI bus from the tape drive, but allows the SCSI connectors on the sub-plate to remain connected. Do not disconnect these cables.

3. Use a flat blade screwdriver to loosen the tape drive thumbscrew (see figure 111).

Caution:
Make sure the thumbscrew is loosened fully before trying to remove the sub-plate.

4. Pull the tape drive out of the library, using the tape drive handle on the left side of the tape drive.

To install the new tape drive:
1. Remove the SCSI sub-plate from the new tape drive:
   a. Use a flat-blade screwdriver to loosen the two thumbscrews on the SCSI sub-plate (see figure 111).

Caution: Make sure the thumbscrews are loosened fully before trying to remove the sub-plate.

   b. Pull the SCSI sub-plate handle to disconnect the SCSI sub-plate from the drive.
   c. Save the SCSI sub-plate.
2. Slowly insert the new tape drive into the library until the connectors are seated.
3. Tighten the tape drive thumbscrew using a flat-blade screwdriver.
4. Install the old SCSI sub-plate (still connected to the SCSI bus) on the new tape drive.
5. Tighten the two sub-plate thumbscrews using a flat-blade screwdriver.
6. Return power to the drive by setting the Drive Power option to ON (refer to Turning Off Drive Power on
   page 172).
7. If the host does not detect the presence of the tape drive, check the drive SCSI ID. If the drive SCSI ID
is:
    • Valid, the tape drive may be defective. Contact Customer Support.
    • Invalid, the SCSI sub-plate has failed and needs to be replaced (see Replacing the SCSI Sub-Plate).
8. Use a host SCSI program to check the data transfer performance of the drive.

To replace the SCSI sub-plate:
Caution:
This procedure is necessary only if you performed the procedure in Installing the New Tape Drive, the tape
drive SCSI ID is invalid, and the host does not detect the presence of the tape drive.

1. Suspend all host activity on the SCSI bus.
2. Power off the drive by setting the Drive Power option to OFF (refer to Turning Off Drive Power on page
172).
3. Disconnect the cables from the old SCSI sub-plate.
4. Remove the old SCSI sub-plate from the drive:
   a. Use a flat-blade screwdriver to loosen the two thumbscrews on the SCSI sub-plate (see figure 111).

Caution: Make sure the thumbscrews are loosened fully before trying to remove the sub-plate.

    b. Pull the SCSI sub-plate handle to disconnect the SCSI sub-plate from the drive.
5. Install the new SCSI sub-plate on the tape drive.
6. Tighten the two sub-plate thumbscrews using a flat-blade screwdriver.
7. Replace the SCSI cables you removed in step 3.
8. Return power to the drive by setting the Drive Power option to ON (refer to Turning Off Drive Power on
page 172).
9. Ensure that the drive LED on the back of the drive canister turns on.

If the host does not detect the presence of the tape drive, contact Oracle Technical Support Center.

Use the packing material from the replacement drive to return the defective drive to Oracle.

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
