Troubleshooting And Diagnostics; Installation Problems - ADIC SCALAR 24 Installation And Operation Manual

This chapter contains some general suggestions to aid you in solving problems.

Installation Problems

Usually, problems encountered during the installation of your Scalar 24 are caused by improper SCSI bus
configuration application software configuration errors or by an OS that has not been correctly configured.
If the application software that you are attempting to use is not communicating with your library after
installation, check the following:
Firmware
Compatibility
SCSI IDs:
SCSI Cabling:
Termination:
System Compatibility:

Troubleshooting and Diagnostics

Use the library operator panel to verify that the drive firmware matches
the firmware version listed for that drive type in the Compatibility Matrix
of the Scalar 24 Release Notes. If your Scalar 24 has two drives, verify
that the firmware on both drives matches the levels in the matrix.
Make sure that the IDs you selected for the Scalar 24 robotics and tape
drive are not the same as the ID used by any other SCSI device on that
bus, including the host SCSI adapter card.
Verify that all SCSI cables are securely connected at both ends and
that the jack screws are secured. Also, check the length and integrity of
your SCSI cabling. The total length of a SCSI bus must not exceed 12
meters (39.4 feet). Replace suspect cables with known good cables.
NOTE: The length of the internal SCSI cabling inside your Scalar
24 is one foot for each drive. This length must be included in any
calculations of bus length.
Check that all SCSI buses are properly terminated.
Ensure that your Scalar 24 and its tape drive(s) are compatible with the
SCSI adapter card and application software you plan to use. The SCSI
adapter card must be LVD compatible. Most application software
websites publish compatibility information.
