HP StoreEver 1/8 G2 Tape Autoloader User and Service Guide (AK377-96024, December 2012)

LTFS Automation License Support
The HP StoreOpen Automation application extends the Linear Tape File System (LTFS) functionality
by presenting an autoloader or library and its tape cartridges as a collection of folders for easy
data access and management. For more information about LTFS capabilities, visit the StoreOpen
website: http://www.hp.com/go/StoreOpen
Enabling the LTFS feature requires a license for the autoloader. Use the RMI Configure: License Key
screen to manage the license key.
To generate a 60-day temporary license without cost:
1. Navigate to the RMI Configuration: License Key screen.
2. Click Generate Temporary LTFS License.
NOTE: Download the LTFS software before generating the temporary LTFS license.
To apply the permanent license:
1. Navigate to the RMI Configuration: License Key screen.
2. Enter the license key and then click Submit. The permanent license takes effect when the
autoloader is rebooted.
Interface specifications and requirements for parallel SCSI drives
The parallel SCSI autoloaders use the Ultra 320 SCSI LVD interface. The autoloaders use a separate
SCSI ID for each tape drive, with dual LUNs on the master drive's SCSI ID to control the tape drive
(LUN 0) and autoloader robotic (LUN 1). HP recommends that each Ultrium tape drive be put on
its own bus when possible.
The parallel SCSI autoloader incorporates a wide SCSI-2 or SCSI-3 Low-Voltage Differential (LVD)
SCSI bus. Make sure your SCSI host adapter or controller supports these standards.
IMPORTANT: The tape autoloader is NOT compatible with a high-voltage differential (HVD) SCSI
bus. Do not put the autoloader on a narrow (50-pin) parallel SCSI bus because doing so will
severely degrade performance.
Parallel SCSI host bus adapters (HBAs)
For optimum performance, place the autoloader on its own SCSI bus with a host bus adapter that
can transfer data as fast as the autoloader can read and write. The HBA must also be supported
by your operating system. For current HBA compatibility information, see the EBS matrix at http://
www.hp.com/go/ebs.
IMPORTANT: Do not connect an Ultrium tape drive to an SE SCSI bus, as it severely degrades
autoloader performance. A single-ended SCSI host bus adapter severely degrades autoloader
performance and limits cable length. Also, if any SE devices are on the SCSI bus, all of the devices
on the bus slow down to SE speed, severely degrading performance.
Multiple LUN support
The autoloader uses a single SCSI ID and two logical unit numbers (LUN). LUN 0 controls the tape
drive and LUN 1 controls the robotic. The autoloader requires an HBA that supports multiple LUNs.
If multiple LUN support is not enabled, the host computer cannot scan beyond LUN 0 to discover
the autoloader. It just sees the tape drive.
Parallel SCSI HP Smart Array controllers, RAID controllers, and most on-board HBAs do not support
multiple LUNs. For current HBA compatibility information, see the EBS matrix at http://www.hp.com/
go/ebs.
IMPORTANT: The autoloader requires an HBA that supports multiple LUNs, which is also called
“LUN scanning.”
