Installing the A6828A Adapter
Specifying SCSI Parameters
Chapter 242
Path (dec) Initiator ID SCSI Rate Auto Term Bus Width
----------------- ------------ --------- --------- ---------
0/0/10/0/0 7 MAX ON MAX
In this example, the HBA’s bus width is MAX (shown in bold in the
previous listing). As mentioned earlier, this is the firmware suggested
default setting.
If you want to retain the bus width, type main to go back to the “Main
Menu”.
If you want to change the bus width (for example, because you have
Narrow devices on the SCSI bus and you are having problems with
the connection), go to step c.
c. If you are still in the “Service Menu,” type the following command:
scsi
path
width
new_bus_width
where,
path
is the HBA’s path and
new_bus_width
is what you want
to set the HBA’s bus width to (8, for this example).
Therefore, using the information for the HBA in step b, type the
following:
scsi 6/0/4/0/0 width 8
This changes the HBA’s bus width to 8.
To ensure that the bus width has changed, you can repeat step b to
display the HBA’s bus width.
When you have fixed the problem with the connection, and you want
to change the adapter’s bus width back to MAX, go to step d.
d. If you are still in “Service Menu”, type the following command:
scsi
path
width
new_bus_width
where,
path
is the HBA’s path and
new_bus_width
is what you want
to change the HBA’s bus width to (MAX, for this example).
Therefore, using the information for the HBA in step c above, type the
following:
scsi 0/0/10/0/0 width 0
This changes the HBA’s bus width back to MAX.
To ensure that the bus width has changed, you can repeat step b to
display the HBA’s bus width.
