1. to map the parameters for all PCI cards installed in the server, enter the info io command
at the EFI shell prompt.
A list of all the devices that are installed in the HP Integrity rx4640 server and managed by
EFI drivers displays. The output could look like this:

In the preceding example, a single SCSI interface is shown in the listing. The information
for both channels of the SCSI interface 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 SCSI interface (the first two bold lines). For each channel of
this SCSI interface, note the following information:
• Bus #—identifies the bus the device is on; for the SCSI interface, this is the same for
both channels. In this example, the bus number is 20.
• Dev #—the ID the device is assigned on the bus; for the SCSI interface, this is the same
for both channels. In this example, the SCSI interface 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 interface has two channels, one channel is 00
and the other is 01.
• Vendor ID—shows the device’s vendor ID; for the SCSI interface, this is the same for
both channels. For all the SCSI interface the ID is 0x1000.
• Device ID—shows the device ID; for the SCSI interface, this is the same for both
channels. For the SCSI interface the ID is 0x0030.
• Slot #—identifies the physical card slot in the server where the SCSI interface is
installed; for the SCSI interface, this is the same for both channels. In this example, the
SCSI interface is on the I/O baseboard therefore the in slot number is xx.
• Path—identifies the device’s path; for the SCSI interface, this is the same for both
channels. In this example, the SCSI interface path is Acpi(HWP0002,200)/Pci(1|0)
for channel A and Acpi(HWP0002,200)/Pci(1|1) for channel B.
Using the SCSI interface information from the example above, the pieces of information
that, combined, tell you this is a SCSI interface are the following (shown in bold, for
highlighting purposes):
00 20 01 00 0x1000 0x0030 xx Acpi(HWP0002,200)/Pci(1|0)
00 20 01 01 0x1000 0x0030 xx Acpi(HWP0002,200)/Pci(1|1)
