Itanium-Based System
If the HP A6829A HBA is installed in a supported Itanium-based
system, use the following procedure to set the bus width:
Step 1. At the EFI Shell prompt, issue the drivers command as illustrated in
the following example:

Step 2. Find the driver handle designation <drvr_handle>.
For the A6829A HBA, the <drvr_ handle> designation will be in the DRV
column that corresponds to the LSI Logic Ultra160 SCSI Driver
listing in the DRIVER NAME column.
In the preceding example, there are two versions of the LSI Logic
Ultra160 SCSI Driver. The <drvr_handle> designations that
correspond to the two LSI Logic Ultra SCSI Drivers are 20 and 21.
Step 3. Find the controller handle designation, <cntrl_handle>.
At the EFI Shell prompt, issue the drvcfg command as illustrated in
the following example:
