Connecting More than one FastStor 2

If you are connecting more than one autoloader on the same SCSI channel, connect each unit to
the previous unit with an additional shielded interface cable. It does not matter which SCSI
connector on each autoloader you connect the interface cable to. Each SCSI ID comes predefined
with each autoloader. Make sure that you configure each autoloader unit with its unique drive SCSI
ID and autoloader ID. Your autoloaders will not function properly if they have the same SCSI IDs,
see Viewing or Changing the SCSI
chain.

Preparing the Host System

At this point you need to refer to your software installation guide for instructions on installing the
backup/controlling software for the autoloader onto the host system. Read through the
System Adapter and Connection Guidelines

SCSI Host System Adapter and Connection Guidelines

If necessary, install a SCSI host system adapter, software, and compatible driver(s). Refer to the
manuals for the host system and SCSI host system adapter for detailed instructions. In addition,
follow these general guidelines:
The LVD host system bus adapter is recommended. A single ended SCSI host
NOTE:
system bus adapter does work, but can severely degrade performance. Also, if
there are any SE devices on the same SCSI bus, the entire SCSI bus
negotiates down to SE speed and can severely degrade performance.
• When the host server system is powered on, install software, and/or driver(s) that are
compatible with the autoloader. Most backup software packages require an additional
module to communicate with the autoloader robotics.
• If the host server system is connected to a network, check with the system administrator
before turning off power.
• Use proper procedures to prevent electrostatic discharge (ESD). Use wrist-grounding
straps and anti-static mats when handling internal components.
• Make sure that the host server system has an open expansion slot.
• Make sure that your backup application supports the SCSI host system adapter.
Depending on the server configuration, you may need to change the SCSI IDs of the
autoloader (see
• Ensure the autoloader is properly terminated. If the autoloader is the only SCSI device—
other than the SCSI host system adapter—on the selected SCSI bus, it must be terminated.
Likewise, if the autoloader is physically the last SCSI device on the SCSI bus, it must be
terminated. Only the devices physically at the beginning and end of the SCSI bus should
be terminated.
• Verify the connection between the autoloader and host system by making sure that the host
server system's operating system recognizes the autoloader:
