Scalar i40 and Scalar i80:
Tape Drive Replacement
Qauntum recommends that you remove and install tape drives with the library
power on. It is faster and keeps all non-affected drives and partitions active. To
do this, carefully follow the instructions below, to prevent data loss or damage
to the Scalar®i40 or Scalar i80 library.
The tape drive always resides in a drive sled, and together they are effectively
one unit. If you order a new or replacement tape drive, it will already be
installed in a sled.
Caution: Do not remove the tape drive from the drive sled.
Note: For multiple tape drive installs in which you are changing control paths,
install and verify the tape drives one at a time, rather than all at once.
To replace a tape drive in the library, refer to the following sections:
•Taking ESD Precautions on page 2
•Preparing Partitions and Control Paths on page 2
•Removing a Tape Drive from the Library on page 4
•Installing a Tape Driveon page 5
•Replacing a Tape Drive with a Filler Plate on page 7

2Taking ESD Precautions
Taking ESD Precautions
To avoid damaging static-sensitive parts while performing this procedure,
observe the following precautions:
• Use an antistatic wrist strap. If you do not have one, touch the outside of
the library on the sheet metal before touching any components, to
discharge static from your body.
• Keep static-sensitive parts in their original shipping containers until ready
for installation. Look for the ESD sticker to identify static-sensitive parts.
• Avoid touching connectors and other components.
Note: Dry climates and cold-weather heating environments have lower
relative humidity and are more likely to produce static electricity.
Preparing Partitions and Control Paths
Depending on the types of tape drives you are removing and installing, you may
need to reconfigure library partitions or change the control path before you
remove and replace the tape drive.
There are four different types of installation, described in the table below.
Follow the instructions in the table before proceeding to the remove/install
procedures.

Preparing Partitions and Control Paths 3
Replacing a tape drive that is
assigned to a partition with a
tape drive that has the same:
• Interface type (Fibre Channel
or SAS),
and
• Form factor (half-height or
full-height),
and
•Vendor
Install the replacement tape drive
in the same slot as the removed
tape drive.
There are no special instructions
unless the tape drive you are
replacing is the control path in a
partition with multiple tape
drives, and you want the
partition to remain online during
the replacement procedure.
In this case, select another tape
drive as the control path. From
the Web client, use the Setup >
Control Path menu path.
Replacing a tape drive that is
assigned to a partition with a
tape drive that has a different:
• interface type (Fibre Channel
or SAS),
or
• form factor (half-height or full-
height),
or
•vendor
• If the partition contains only
one tape drive, delete the
partition before removing the
tape drive, and then re-create
the partition after you install
the replacement tape drive.
• If the partition contains
multiple tape drives, and the
tape drive you want to replace
is not the control path, delete
the tape drive from the
partition.*
• If the partition contains
multiple tape drives, and the
tape drive you want to replace
is the control path, select
another tape drive as the
control path.** Then delete
the tape drive you want to
replace from the partition.*
*To delete tape drives from
partitions, select Setup >
Partitions from the Web client.
**To modify the control path,
select Setup > Control Path
from the Web client.

4Removing a Tape Drive from the Library
Removing a Tape Drive from the Library
Caution: Do not remove a tape drive that is currently performing an
operation.
1Save the library configuration.
aFrom the Web client, select Tools > Save/Restore Configuration.
bSelect Save System Configuration and Apply.
2Make sure the tape drive you want to remove is empty of media. From the
Operator panel, select Actions > Tape Drive and select Unload.
3Take the tape drive you want to remove offline.
aFrom the Operator panel, select Actions > Tape Drive, and select
Change Mode.
bSelect the tape drive and press Modify.
cPress the Down button to select Offline, then press Apply.
4Disconnect the cable from the back of the tape drive.
5Unscrew the captive thumbscrews securing the drive sled to the back of the
library. Half-height tape drives have two thumbscrews (see Figure 1). Full-
height tape drives have four thumbscrews.

Thumbscrews
6Using the handle, pull the drive sled out of the library. It should slide out
smoothly and easily.
Wait at least 10 seconds before installing a replacement tape drive to allow
the library to recognize that the tape drive has been removed.
7Install a replacement tape drive following the instructions (see Installing a
Tape Driveon page 5). If any empty slots remain, install a filler plate in the

empty slot (see Replacing a Tape Drive with a Filler Plate on page 7).
8If you are returning the tape drive to Quantum, wrap it in the antistatic bag
in which the replacement tape drive is wrapped, then finish packing it in the
same packaging materials from the replacement tape drive. Ship the tape
drive to Quantum using the RMA materials included in the packaging.
Installing a Tape Drive
1Insert the tape drive into the empty drive slot.
The “shelf” on the bottom of the drive sled fits into the notch in the library
chassis and slides on the plastic guide rails (see Figure 2). The tape drive
must be level to slide in smoothly. When the tape drive is correctly inserted,
you will feel a slight “click” as the tape drive sled connector connects into its
mating connector in the library chassis.
Figure 2 Installing a Tape Drive
2Tighten the tape drive’s captive thumbscrews finger tight to secure the tape
drive to the library chassis.
The tape drive LED illuminates red for up to 30 seconds. Then the tape drive
fan starts and the LED turns amber, indicating that the tape drive is offline.
3Connect the tape drive cable from the tape drive to the host.
If the firmware on the newly installed tape drive is different from the
standard configured on the library, the library will automatically autolevel
the new tape drive’s firmware upon installation. (See the
Scalar i40 and
Scalar i80 User’s Guide
for details about tape drive firmware autoleveling).
Autoleveling takes about 7 minutes. A message appears on the Operator
panel, indicating that autoleveling is taking place.

6Installing a Tape Drive
If autoleveling is not required, the tape drive takes about 2 minutes to reach
a ready state.
4If needed, add the new tape drive to an existing partition or create a new
partition for it.
aFrom the Web client, select Setup > Partitions.
bComplete the necessary screens.
5Bring the tape drive online, if it is not online already.
aFrom the Operator panel, select Actions > Tape Drive and select
Change Mode.
bSelect the tape drive you want to bring online and press Modify.
cUse the Up button to change the mode to Online, then press Apply.
The tape drive LED turns green.
6Verify the installation by reviewing the Library Configuration report:
aFrom the Web client Reports > Library Configuration.
bMake sure that the new drive is online, in the correct partition, and has
the control path status that you want. You may need to refresh your
Internet browser.
7Verify that the host computer and backup applications can see the new tape
drive configuration correctly.
8If any empty slots remain, install a filler plate in the empty slot (see
Replacing a Tape Drive with a Filler Plate on page 7).
Caution: Filler plates are required to maintain proper library cooling. Do
not run the library with uncovered slots.
9Run the tape drive diagnostic test on the newly installed tape drive to be
sure it is functioning correctly:
aInstall a scratch tape in the top I/E station slot.
bIf manual cartridge assignment is enabled, assign the scratch tape to
the System partition.
cFrom the Operator panel, select Tools > Diagnostics.
dContinue through the next few screens to run the tape drive test on the
replaced tape drive.
If a problem is found during testing, you receive a diagnostic ticket. See the
Scalar i40 and Scalar i80 User’s Guide for more information about the tape
drive test.

Replacing a Tape Drive with a Filler Plate 7
Replacing a Tape Drive with a Filler Plate
The filler plate is half-height in size. If you remove a full-height tape drive, you
must install two filler plates to cover the opening.
1The tape drive filler plate has no “top” or “bottom” orientation – it can go in
either way (see Figure 3 on page 7).
2Slide the filler plate into the slot, and tighten the thumbscrews.
