Step 2. Determine the HBA’s path by doing the following:
a. If you are already at the “Main Menu,” type in (for “Information
Menu”); go to step b.
If you are not at the “Main Menu,” type main (to return to the “Main
Menu”), type in (for “Information Menu”), and then go to step b.
b. At the “Information Menu,” type io (to display I/O interface
information). The output is as follows:
PCI DEVICE INFORMATION
Path Bus Slot Vendor Device
Description (dec) # # Id Id
----------- ----- --- ------ ------ ------
.
.
SCSI bus cntlr 0/0/10/0/0 80 2 0x1000 0x0021
SCSI bus cntlr 0/0/10/0/1 80 2 0x1000 0x0021
.
.
In this example, the HBA’s path is 0/0/10/0/0 and 0/0/10/0/1
(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 and 1 for channel B.
Step 3. Display (and optionally change) the HBA’s bus width 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 width
where, path is the HBA’s path (from step 1).
Therefore, using the information for channel A of the HBA in the
example in step 1, type the following:
scsi 0/0/10/0/0 width
This displays the HBA’s bus width. The output is as follows:
