IBM Ultrium Gen 6, Installation And User Manual

Page: 24 / 118

A drive with a SAS interface can be linked directly to controllers. SAS is a
performance improvement over traditional SCSI because SAS enables multiple
devices (up to 128) of different sizes and types to be connected simultaneously
with thinner and longer cables; its full-duplex signal transmission supports 6.0 Gb
per second. SAS drives can be hot-plugged.
SAS drives will auto-negotiate speed. There are no configurable topologies, and
therefore no feature switches associated with SAS.
Supported Servers and Operating Systems
The latest supported attachments.
To determine the latest supported attachments, visit the IBM ServerProven website
for System x Tape Backup Units: http://www-03.ibm.com/servers/eserver/
serverproven/compat/us/xseries/storage/tmatrix.html.
For specific instructions about attaching the drive, see Chapter 2, “Tape drive
installation,” on page 9.
Supported device drivers
Getting the supported device drivers for the tape drive.
To download the latest device drivers, go to http://www-947.ibm.com/support/
entry/portal/, and complete the following steps.
Note: Changes are made periodically to the IBM website. The actual procedure
might vary slightly from what is described in this document.
1. Go to http://www-947.ibm.com/support/entry/portal/.
2. In the Search support & downloads text field at the top right hand corner of
the screen, type tape files and press Enter .
3. In the list of search results, click the link Tape Files (index) - Software for tape
drives and libraries .
Ethernet port
The IBM LTO 6 Half High Tape Drive has a single 1 Gbps Ethernet port on the
rear panel, with a RJ45 connector.
The default IP address is 169.254.0.3 , but the drive’s IP address can be changed as
needed. Refer to the IBM Tape Diagnostic Tool from the http://www-947.ibm.com/
support/entry/portal/ website on how to make this change.
The Ethernet port is used only for monitoring drive status and servicing the drive,
not for data transmission.
Linear Tape File System (LTFS)
The Linear Tape File System (LTFS) is a file system that works in conjunction with
LTO Generation tape technology to access data stored on an IBM tape cartridge.
LTFS uses the file system’s format and resources of the operating system (OS) on
which it is running to graphically display the contents of a tape cartridge in the
OS’s graphical user interface (GUI) format; typically a folder/tree structure. Using
