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:
The service aid transmitted a SCSI Inquiry Command and received a valid
response back without any errors being detected.
The service aid transmitted a SCSI Inquiry Command and did not receive any
response or error status back.
The service aid transmitted a SCSI Inquiry Command and the adapter indicated
a SCSI bus error.
The service aid transmitted a SCSI Inquiry Command and an adapter error
occurred.
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.
When the adapter is selected the SCSI Bus Address Selection menu is displayed.
This menu allows the user to enter which address to transmit the SCSI Inquiry
Command.
Once the address is selected the SCSI Bus Test Run menu is displayed. This
menus allows the user to transmit the SCSI Inquiry Command by pressing the Enter
key. The service aid then indicates the status of the transmission. When the
transmission is completed, the results of the transmission are displayed.
Notes:
A Check Condition can be returned when there is nothing wrong with the bus
or device.
AIX does not allow the command to be sent if the device is in use by another
process.
