Specifying SCSI Parameters
The following SCSI parameters may be configured for the SCSI board:
• SCSI ID (SCSI initiator ID)
• Maximum data transfer rate (SCSI rate)
• Bus width
• Whether the HBA is bootable (driver support)
• Avoid bus resets (secondary cluster server)
Using the SCSI Setup Utility
Step 1. At the EFI shell prompt, type this command to map the parameters for all PCI cards installed in the system:
info io
A list of all the devices that are installed in the hp Integrity rx4640 Server and managed by EFI drivers is
displayed. The output may look like this:

In the example above, two SCSI boards are in the listing. The information for both channels of both SCSI boards is
shown in bold, for highlighting purposes.
For each channel of the SCSI board, you need to note certain information. As an example, look at the information
for the first SCSI board (the first two bold lines). For each channel of this SCSI board, note the following
information:
• Bus #—identifies the bus the device is on; for the SCSI board, this is the same for both channels. In this
example, the bus number is 40.
• Dev #—the ID the device is assigned on the bus; for the SCSI board, this is the same for both channels. In
this example, the SCSI board is device 01.
• Fnc #—identifies the channel of the device (00 for channel A, 01 for channel B, and so on). In this example,
because the SCSI board has two channels, one channel is 00 and the other is 01.
