System Test Summary Notes:
• Data is destroyed on hard disks in the manufacturing environment, except
for disks with VMS installed.
• Data is not destroyed on hard disks in the Digital Services environment.
• All expansion boxes must have power supplied before the system box is
powered up, or the expansion box devices will not be configured.
• Common causes of errors or devices missing from the configuration include
the following:
The SCSI bus is not terminated.
All device IDs are not unique.
Internal cables to the drives are disconnected.
• The summary screen lists the test results by device ID.
• When in the Digital Services environment, media must be present in all
removable media devices in order for devices to be fully tested.
• In order for writes to occur, a key pattern must be installed on writable
removable media (floppies and tapes). The key pattern is put on the media
by the SCSI utilities. The SCSI utilities are described in Section 2.12.7.
• Table A–14 lists the SCSI system test error codes.
