New Features and Enhancements
The Scalar DLC 2.7 new features and enhancements include the following:
• Additional Drive Support
The Scalar DLC now supports IBM LTO-4 FC drives. The LTO-4 drive provides industry standar d
encryption capabilities and incorporates native encryption. LTO-4 increases capacity and
performance levels from the previous LTO-3 generation.
• Tape Alert Support
A drive issues a tape alert whenever there is a proble m in the dri ve that rela tes to a ta pe car tridge.
To determine if the problem belongs to a drive or to a specific tape cartridge, you can use the ta pe
alert report functionality to cross-reference tape alerts for drives and tape cartridge s over a specified
period of time
6-00335-10 Rev A
You can view tape alerts on the Tape Alert tab of your library or you can directly create and view
tape alert reports using the Report function. To access the tape alerts feature, use Configuration
> Logical. In the Report Criteria dialog box, you can choose how you want to sort the report and
how you want to group the report.
You can sort the reports by:
•Drive
• Drive serial number
• Tape alert
• Count
• Last occurrence
You can group reports by:
•Cartridge
• Tape Alert
•Drive
You can export the report into either a spreadsheet or into a PDF file. For more information, see the
Scalar DLC Reference Guide.
• Cleaning Enhancements
• Drive Cleaning
• When a tape alert is issued that indicates cleaning is necessary, the drive is automatically
cleaned.
• You can manually choose a drive on the Library tab to initiate cleaning.
If Auto Clean is enabled, you can import and export cleaning cartridges. To import cleaning
cartridges, go to Configuration > Physical > Auto Clean Cartridge pane, and then click
Import Clean Cartridges. To remove expired cleaning cartridges, click Export expired
Cleaning Mediums.
To use the auto clean functionality, you must first create a cleaning partition. If you choose to
use the Auto Clean Cartridges feature, you do not need to configure clean pools. To create a
cleaning partition, you can use the Create Clean Partition Wizard.
• Creating Clean Partitions
Cleaning partitions contain only cleaning cartridges designated for auto-cleaning operations.
Assigned cartridges in a cleaning partition are not considered part of the logical library.
You can create cleaning partitions during the init ia l config uration and at a ny time afte r th at, as
long as unassigned slots are available. If no slots are available, you can still create a cleaning
partition using the Create Cleaning Partitions wizard.
The new cleaning enhancements are SCSI-only For more information, see the Scalar DLC
Reference Guide.

• DAS/ACI Firewall Options
The Scalar DLC offers enhanced firewall functionality. You can access the new options using
Configuration > Clients > DAS Clients
• Use FireWall: Select to activate the TCP/IP receiver for the client
If you choose to enable Use FireWall, you also have the following options:
• Accept only FW connection: Select to refuse the RPC connection
• TCP/IP Port: The TCP/IP port address of the library
• ROBAR Coordinate Remapping
Improvements allow ROBAR clients to:
• Address all storage slots in larger libraries
• Remap physical library element addresses to logical element addresses that do not exceed
ROBAR limits
• SYN Attack Detection Settings
If you are running Windows 2003 with SP1 or later, prior to initiating the installation of SDLC 2.7
software, the system automatically performs a check of the Windows registry to determine if the
parameter that handles the firewall protection for SYN attacks is enabled or disabled. To prevent
MS SQL conflicts and abnormal termination of Scala r DLC, it reco mm end e d th at yo u dis ab le th e
SYN attack detection setting.
After choosing Software > Scalar DLC > Install, you are prompted to disable the detection
parameters.
If you are installing Scalar DLC on a Windows 2000, or a Windows system where the detection
setting is already enabled, the parameter check will silently exit and the Scalar DLC installation will
continue.
For more information, see the Scalar DLC Reference Guide.

Do not use the same media volsers for both
DAS and SCSI clients. Neither the S10K nor
the Scalar DLC can handle the duplicate

assigned to the DAS logical library and one
set assigned to the SCSI logical library.
Export all required cartridges first and then
make all needed configuration changes.
Would the removal of HotFix 48 fails, just
ignore this error and remove Scalar DLC 2.5
