Preparing the host and verifying the connection
Follow these general guidelines:
• Connect to a suitably-rated HBA, see ” SCSI host bus adapters (HBAs) ” on page 18. Remember
that if there are any SE devices on the same SCSI bus, the entire SCSI bus will negotiate down to
SE speed and severely degrade performance.
• When the host server is powered on, install software and/or driver(s) that are compatible with
the autoloader. Software compatibility information is available at www.hp.com/go/automated.
Most backup software packages require an additional module to communicate with the
autoloader robotics.
• If the host server is connected to a network, check with the system administrator before turning
off power.
• Use proper procedures to prevent electrostatic discharge (ESD) (see ” Electrostatic Discharge ” on
page 95). Use wrist-grounding straps and anti-static mats when handling internal components.
• Make sure that the host server has an open expansion slot.
• Make sure that your backup application supports the SCSI host adapter.
• For HP StorageWorks 1/8 DLT VS80, Ultrium 960 and Ultrium 448 Tape Autoloader models
make sure that LUN scanning is enabled on the SCSI host adapter (see also ” LUN scanning ” on
page 19).
• Depending on the server configuration, you may need to change the SCSI IDs of the autoloader
(see ” Changing the SCSI ID ” on page 49).
• Ensure the autoloader is properly terminated. If the autoloader is the only SCSI device, other
than the SCSI host 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 located at the beginning and end of the SCSI bus should be terminated.
• Verify the connection between the autoloader and host by:
• Installing the HP Library & Tape Tools diagnostic/installation check utility available at
www.hp.com/support/TapeTools . Install this utility onto the host server. This utility verifies
that the autoloader is connected and communicating with the host server. It also verifies that
the autoloader is functioning and provides diagnostic information.
• Confirm the host server’s operating system recognized the autoloader in Microsoft®
In Windows ® Server 2003 or in Windows 2000 ® by going to:
Settings > Control Panel > System > Hardware > Device Manager > Tape Drive and/or
Media Changer .
For more information on verifying the connection of SCSI devices, consult the operating system
documentation.
