In this example, the HBA’s path is 0/0/10/0/0 (shown in bold in the
listing above, for highlighting purposes). Note that the last (farthest
right) digit is the channel number—0 for channel A.
Step 3. Display (and optionally change) the HBA’s maximum data transfer rate
by performing the following steps:
a. If you are already at the “Main Menu,” type ser (for “Service Menu”);
go to step b.
If you are not at the “Main Menu,” type main (to return to the “Main
Menu”), type ser (for “Service Menu”), and then go to step b.
b. In the “Service Menu,” type the following command:
scsi
path
rate
where
path
is the HBA’s path (from step 1).
Therefore, using the information for the HBA in the example in step
1, type the following:
scsi 0/0/10/0/0 rate
This displays the HBA’s maximum data transfer rate. The output is
as follows:
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 maximum data transfer rate is MAX
(shown in bold in the previous listing, for highlighting purposes). As
mentioned earlier, this is the firmware suggested default setting, and
it allows the A6828A’s maximum data rate (160 MB/s) to be used.
