Purpose of This Release
This release adds new features and enhancements, and it resolves issues found in previous releases of the
Scalar 10K library. This document lists the new features, enhancements, known issues, resolved issues,
and drive and auxiliary firmware compatible with the library. Visit www.adic.com for additional information
about the Scalar 10K library.
New Features and Enhancements
This release of the Scalar 10K library includes the following new features and enhancements:
• IBM 3592-J1A tape drive support
Single-aisle and dual-aisle libraries now support the native Fibre Channel version of the IBM
3592-J1A tape drive. The 3592-J1A tape drive is enclosed in a drive sled designed specifically for
the 3592-J1A, referred to as the 3592-J1A drive sled. Both re-writable cartridges (media IDs “JA”
and “JJ”) and Write Once Read Many (WORM) cartridges (media IDs “JR” and “JW”) are supported.
Libraries that contain 3592-J1A drives support mixed media configurations consisting of 3590 and
LTO types only.
The library has a new Drive Module (DM) specifically designed for 3592-J1A tape drives only. Other
drives types are not supported in this DM, and other types of modules in the library do not support
3592-J1A tape drives. The 3592-J1A DM supports from 1 to 16 hot-swappable 3592-J1A tape
drives.

6-00016-22 Rev A
The 3592-J1A tape drive supports logical serial number addressing. The library assigns a logical
serial number to a 3592-J1A tape drive in a specific location. This is not the same serial number as
the one that the manufacturer assigns to the physical tape drive itself. If a 3592-J1A tape drive is
replaced by another 3592-J1A tape drive in the same library location, the logical serial number
remains the same. From the host’s perspective, the replacement drive is the same as the original
one.
• LTO-3 tape drive support
The library now supports the native FC version of the LTO-3 tape drive. The LTO-3 uses the
standard Universal Drive Sled (UDS). The media ID for LTO-3 cartridges is “L3”.
• Gripper firmware improvements
Library software improves gripper teach and handling operations and supports brushless and
brushed grippers.
• Gripper serial number stored in EEPROM data format
LGR (gripper) cards now include the gripper serial number in Electrically-Erasable Programmable
Read-Only Memory (EEPROM). In addition, library logs now include the gripper serial number.
• Teach Tape feature for LTO linear storage
The new Teach Tape feature refines teach positions and improves Get and Put operations for LTO
linear storage only. This feature should be used by ADIC service personnel only.
• Auto-Reteach feature for storage, drives, and I/E station magazines
The new Auto-Reteach feature, when enabled, causes the library to periodically reteach itself when
Get or Put operations against storage, tape drives, or I/E station magazines retry a certain number
of times. This feature can be enabled or disabled only by ADIC service personnel.
• Menu commands removed
Add was removed from the Teach menu, and the Learn, Manual Get, and Manual Put commands
were removed from the Advanced menu because they were no longer needed.
• TapeAlert information for LTO and 3592-J1A tape drives and media
The library now posts TapeAlert information in the Command and Error logs. TapeAlerts indicate
specific faults with LTO or 3592-J1A tape drives or media. When a TapeAlert occurs to indicate that
a 3592-J1A tape drive needs to be replaced, the library issues a SAC 9C. When a TapeAlert occurs
to indicate that an LTO tape drive needs to be replaced, the library issues a SAC 96. All other
TapeAlerts cause the library to issue SAC ED messages, which appear in the Command and Error
logs. Some SAC EDs also generate operator intervention messages, which are displayed on the
Operator Panel. Both SAC 9C and SAC ED are new for this release.
• Weekly retry statistics added to Command and Error logs
A new section in the Command and Error logs provides weekly statistics about retry activity in the
library.
• Verification Tests
The library now provides a series of verification tests to confirm correct library installation. ADIC
service personnel can run the verification tests from the Operator Panel. The Verification Test Log
provides the results of individual verification tests.
• Automatic calibration
The library will automatically calibrate (home) the accessor assembly with gripper and the Tower
Modules (TMs).
• Powering on a tape drive while varied off
A tape drive that is varied off can now be activated (power turned on) for servicing purposes.

• Last SAC message stored before power cycle
The library now stores the last-occurring SAC and error code in non-volatile RAM (NVRAM). Upon
request by the Remote Management Unit (RMU), the library sends the stored SAC and error code
to the RMU.

The library assigns 12-character logical serial numbers to 3592-J1A tape
drives. If you use IBM Tivoli
TSM device driver that is later than maintenance release 5.2.4.4 (for TSM 5.2)
or later than 5.3.1.1 (for TSM 5.3) to ensure that TSM can properly identify
3592-J1A tape drives according to their 12-character logical serial numbers.

FUP tape to update a list of drives,
the library correctly posts a “BAD
FIRMWARE MEDIA” operator
intervention message, but continues
to the next drive in the list. The
operation should fail and not
continue.
Manually adjust the vertical
placement of the 3590 tape drive or
the front bezel until the library can
successfully teach the drive.
Physically inspect the drive bay that
the failure indicated or possibly the
bay that is located immediately
before. The bay that is identified by
the failure might not exist.
No applicable workaround is
available.

from drives, the View dialog (Main

than clearing the status.
Make sure that cleaning cartridges
are inserted into the library by using
the Insert Clean Tape command
(Main Menu Commands

This operation physically inserts the

Description Workaround
42204 After Scalar DLC starts up and
configures the library, it issues a
“License has been expired!” notice.
This notice should appear when the
user logs in rather than after the
physical and logical libraries are
configured. In addition, Scalar DLC
should accept license registration
information the first time rather than
requiring the user to enter it twice.

Description
When a SCSI command timeout occurred on the host, the library responded
with a return status of Check Condition, but had no sense information.
Commands that were subsequently issued, such as the TUR command,
indicated that the library was Ready even when the aborted command
continued to run. When the aborted command completed, a return status of
Check Condition was set with a sense key of 0Bh and ASC/ASCQ of 0000h.
In many circumstances, this could cause the library to hang. Also, the aborted
SCSI command did not properly release the SCSI component. Resources
were blocked too long or indefinitely when I/E station actions occurred and
when the RMU was used to vary drives online or offline.

information again.

Serial communications were lost between the Drive Control (LDC) card and
LTO drives, which caused the library to issue SAC 96 error messages to the
Operator Panel and required a re-sync recovery. Now, lost serial
communications cause automatic drive reconfigurations with SAC 96 errors
being issued when reconfigurations fail.

Management Unit (RMU), the library should send the stored SAC and error
code to the RMU.
Communications failure between the RMU and the library caused long delays
between move operations.
During downloads of new images to auxiliary controllers, the setting of
EEPROM-resident bank switching for all auxiliary controllers, including all
failure modes, should be managed properly.
