C.9 SCSI Bus Controllers (SCSi-A and SCSI-B)
This section includes the codes for all SCSI bus controllers on all
VAXstation 3100 systems.
Note A soft error occurs if nothing is connected to the SCSI-B bus.
First line of error code format: WWXX.YYZZ
where WW is the binary mask field of the devices selected
successfully on the SCSI bus (see Table C-11), XX is the binaiy
mask field of the devices tested successfully on the SCSI bus
(Table C-11), YY is a set of binary error flags (see Table C-12),
and ZZ is the status code and error code of the SCSI controller on
the SCSI mass storage controller module (see Table C-13).
Second line of error code format: DDMMSSTT
where the DD is the status of the data in phase of the INQUIRY
command, MM is the status of the message in phase of the
INQUIRY command, SS is the status of the status phase of the
INQUIRY command, and TT is the status of the devices on the
SCSI bus. All of these status codes are identical and are listed in
T&h\e C-14.
The second line of the error code indicates the status of the eight
possible devices on the SCSI bus, including the controller on
the SCSI mass storage controller module. The first code in this
second line is reserved for the SCSI controller on the SCSI mass
storage controller module. Codes 2 through 8 are for the devices
connected to the SCSI bus. See Table 0-14.
