SCSI Bus Analyzer
This service aid provides a means to diagnose a SCSI Bus problem in a free-lance
mode.
To use this service aid, the user should have an understanding of how a SCSI Bus
works. This service aid should be used when the diagnostics cannot communicate with
anything on the SCSI Bus and cannot isolate the problem. Normally the procedure for
finding a problem on the SCSI Bus with this service aid is to start with a single device
attached, ensure that it is working, then start adding additional devices and cables to
the bus ensuring that each one works. This service aid works with any valid SCSI Bus
configuration.
The SCSI Bus Service Aid transmits a SCSI Inquiry command to a selectable SCSI
Address. The service aid then waits for a response. If no response is received within a
defined amount of time, the service aid displays a timeout message. If an error occurs
or a response is received, the service aid then displays one of the following messages:
v The service aid transmitted a SCSI Inquiry Command and received a valid response
back without any errors being detected.
v The service aid transmitted a SCSI Inquiry Command and did not receive any
response or error status back.
v The service aid transmitted a SCSI Inquiry Command and the adapter indicated a
SCSI bus error.
v The service aid transmitted a SCSI Inquiry Command and an adapter error occurred.
v The service aid transmitted a SCSI Inquiry Command and a check condition occur.
When the SCSI Bus Service Aid is entered a description of the service aid is displayed.
Pressing the Enter key displays the Adapter Selection menu. This menu allows the user
to enter which address to transmit the SCSI Inquiry Command.
