6 Unpacking the Tape Drive
Required Tools 0The following tools are required to perform the tape drive upgrade
procedure:
• Flat blade screwdriver
Unpacking the Tape Drive 0
To unpack the tape drive:
1Open the shipping carton.
2Remove the tape drive from the carton.
The tape drive is protected by two pieces of foam and an antistatic bag.
3Remove the foam from the wrapped tape drive. Remove the tape drive
from the antistatic bag.
Installing the Tape Drives 0
To install tape drives in a Scalar 50 Series library:
1At the back of the library, use a flat blade screwdriver to loosen the
captive screws that secure the cover plate to the empty drive bay.
2Set the cover plate aside.
Caution: Use appropriate electrostatic discharge (ESD) precautions
when installing the tape drive.
Note: If this is an initial library installation, it is recommended to turn
the library off prior to installing tape drives. If this is an existing
library that is receiving a tape drive upgrade, the library can
remain powered on.
Note: Each tape drive ships from Quantum with a version of library
firmware as well as drive firmware on the tape drive interface
PWA. When you install the tape drive, the library will check the
version of library firmware on the tape drive and verify if the
firmware is newer than the version currently running. If the
library firmware on the tape drive is newer than the version
currently running on the library, the OCP will prompt you with
the option to upgrade the library firmware.

Completing the Native Fibre Channel Installation 0
After native Fibre Channel tape drives are installed, additional information
must be gathered to complete the installation and verify connectivity.
Competing the native Fibre Channel tape drive installation consists of the
following steps:
Note: The firmware revision on the new tape drive(s) must match the
firmware revision on the currently installed tape drives (of the
same tape drive type). If the new tape drive has a different
revision, you must download the appropriate tape drive firmware
from Quantum and update the drive. All tape drives in the library
must contain the same firmware revision. You can view the tape
drive firmware revision on the OCP under Drive Operations.

•Verifying Library Connectivity
Determining the
WWNs World Wide
Names 0
The media changer (robot) and tape drives within the library have WWNs
World Wide Names assigned to them by the system controller board (SCB).
The WWNs must be determined and recorded both for the customer and for
Quantum customer support. This information is important when replacing
the Fibre Channel SCB and tape drives. Using the following procedures,
complete table 3 and retain a copy of the table for your records. Have this
table available when contacting Quantum Customer Support for any library
or tape drive connectivity issues.

Wide Names
Using the Remote Management to Determine the WWNs 0
To determine the WWNs from the library remote management pages:
1On the host computer, open the internet browser software.
2In the Address field, type http://IPaddress/ where IP address is the IP
address for the Quantum Scalar 50 series library.
3Enter the username and password and click OK.

7Record the WWNs for the media changer and tape drives in table 3.
• Repeat step 6 for all tape drives in the library
or
•Add
04h to the last hex byte to derive the WWN for the next tape
drive.
Example: Drive 0 WWN is 50:05:08:40:16:6B:00, Drive 1 WWN will be
50:05:08:40:16:6B:04, Drive 2 WWN will be 50:05:08:40:16:6B:08.
8To determine the WWN for the media changer, subtract 01h from the next
to last hex byte of the WWN for Drive 0.
Example: Drive 0 WWN is 50:05:08:40:16:6B:00, Media Changer WWN will
be 50:05:08:40:16:6A:00.
Verifying Library
Connectivity 0
To verify the tape drive installation, you should verify that the library and
tape drives are recognized from the host or from the SAN switch.
If the SAN switch is available, it is possible to verify connectivity by
connecting to the switch. There are two ways to directly access the SAN
switch:
•Connect Via a Telnet Session
Note: These numbers are the world wide NODE names for the
library and tape drives. The World Wide Port Name is very
similar to the World Wide Node Name, however, the last hex
byte is 01h greater than the last hex byte of the node name.

To connect via a Telnet session to a SAN switch:
1Connect the service laptop to the SAN switch using an Ethernet cross-
over cable, or by connecting to the LAN (if available).
2On the service laptop, open a command prompt window.
3From the command prompt, enter the following command and press
<Enter>:
telnet <IP address of SAN switch>
The SAN switch login prompt displays.
4Enter the username and password and press <Enter>.

connectivity is verified.
Fibre Channel Connectivity Troubleshooting 0
Refer to the following sections Fibre Channel connectivity troubleshooting:
•Fibre Channel Connectivity Troubleshooting
•SCSI ID Assignment with Native Fibre Channel Tape Drives
Fibre Channel Connectivity
Troubleshooting 0The following section provides Fibre Channel connectivity problems and
resolutions when connecting via Fibre Channel to the SAN switch, or directly
to the library and drives.
1Medium changer and drives are not visible in the device manager
aCheck all cable connections.
bCheck the SAN switch port LEDs for connection status to the library
Fibre Channel HBA and tape drives.
cIf you are connected to the SAN switch, verify that you are connected
to the same zone as the library and tape drives. If you are unsure, try
one of the ports on the SAN switch that a tape drive is connected to.
dVerify that the SAN switch is powered on and operating normally.
Note: If you are not on a port in the same zone as the library and all
of the drives, you will not be able to verify connectivity.
