Spectra 20K and 64K Library AIT-4 Drive Upgrade
SPRT-1061-A-092004
The Sony AIT-4 drives double the Spectra 20K and 64K library capacity and transfer rate.
Review this document for information about AIT-4 and about upgrading your library to
take advantage of AIT-4 drive technology.

Preparation
1. Identify the drives to be upgraded in your Spectra 20K/64K library.
2. Make sure you have an AIT-4 drive for every drive you are replacing, and a
library firmware upgrade diskette.
3. If you are going to return the drives to Spectra Logic (for example, for trade-ins
or pre-purchase), make sure to reserve the drive packaging for later use.
4. Download from the Sony Web site and install on the library’s host system a
driver for the host’s operating system.
5. Make sure all backup procedures are halted, and that you have fifteen minutes
available per drive to be upgraded, so that you can configure, install, and test.

Updating Firmware
If you do not have firmware diskettes, access the library upgrade remotely from the
Spectra Logic site, as outlined in the library user guide or www.SpectraLogic.com.
1. Insert Disk 1 in the LCM disk drive (Figure 1).
2. Reset the LCM by cycling the power or pressing the reset button on back of
LCM.
3. Follow on-screen directions, inserting disks one at a time until operation is
complete.
4. Remove all disks and reset the LCM. The operating system and Library
Controller will now be upgraded.
5. The Library Controller alerts the user Configuration of QIP (X) Bus (X) Does
Not Match Front Panel for each logical library. Select OK. This message does
not appear after all QIPs have been upgraded.
6. Once you have the firmware files added to the local directory, go to Updating
Firmware Using the LC, next.

Updating Firmware Using the LC
1. On the Library Controller, select Toolbars, then select Maintenance. The
Maintenance toolbar displays.
2. Select Update F/W. The Firmware Update screen displays (Figure 1).
3. In File Locations, select Local Directory -> Select Location, then select the
most recent firmware package.
4. Select Update Firmware. The library firmware update process begins. A window
displays a message, asking you to wait.
Caution: Do not interrupt the library while firmware is downloading. The
firmware download takes less than 10 minutes.

Replacing Drives
Moving Original Drives Off-line
1. On the Library Controller, select Toolbars -> General. The General toolbar
displays.
2. Select Drive Config. The Drive Configuration screen appears Figure 2.
3. Select the drive you want to replace, the select Replace. A dialog box series
displays, first asking whether it is Okay to Replace Drive? then “Are you sure
you want to open the door?
4. Select Okay for each. This powers down the drive and disengages the solenoid
latches on the front door. A dialog box displays the message Open Door and
Replace Drive. Close and Latch Door. Tap Okay when complete.
Note: Do not select OK until you have completed the procedure.

Removing Original Drives
1. Use the library door key to open the library door.
2. Pull the old drive out of the drive slot (Figure 3).
3. Slide the new drive firmly into the same slot while pressing it to the right against
the library wall. A red LED on the drive lights up.
4. Close the library door.
5. Secure the lock with the key.
6. Return to the Library Controller, then select OK. The library processes this
change, and may require a few minutes to complete. When the drive has been
configured, another statement displays: The library geometry has changed-
Reloading geometry, your drive information may be invalid. Tap OK.
7. Select OK.
8. Review the Drive Configuration screen. If the drive displays as offline, select
Config, then select OK. The drive now displays as online.
The library automatically configures the new drive with the old drive’s
configuration settings.
9. Repeat this procedure for every drive to be upgraded.

Returning Old Drives
To return old drives to Spectra Logic (for example, if you are trading in the drives, or if
you pre-purchased the new drives), use the AIT-4 drive packaging and return the drives
to Spectra Logic (North America) or contact Support for assistance in determining how
to return the drives.
Completing the Drive Upgrade Process
1. Test your drives. For example, back up a set of data that includes one executable
program; restore the data to a temporary directory; then read the restored data
and run a restored program. Refer to your backup software documentation for a
more specific procedure. After you have performed a drive test successfully,
continue.
2. Restart backup processes
