Installing the A6829A Adapter
Specifying SCSI Parameters
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”; you are finished with the bus width for channel A.
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.
