Description
The
ifhw
utility is executed from a script file, in conjunction with other utilities, to control the
install process. The
ifhw
utility makes intelligent queries against the hardware discovery file.
Queries take the form of a logical expression, and the result of the expression is returned as the
exit status of the tool, which the hosting script can use to conditionally perform actions.

]
hwdiscfilename
This argument specifies the
allboards.xml

PCI IDs found in hardware discovery into device names, such as "Smart Array 6402
Controller."

This argument specifies the query expression.
expression
Examples
The
ifhw
utility might use XML files as input to query the hardware discovery file. The command
line input:
ifhw hwdisc.xml allboards.xml "PCI:Smart Array 6402"
returns the following possible codes:
•
0 (True) if the Smart Array 6402 is present
•
1 (False) if the device is not present
•
2 (Error) if the expression could not be understood
•
-1 or 255 if incorrect number of parameters given
The following expressions, used as shown in the Synopsis, return the indicated result:
•
"PCI:Smart Array 6402"
Returns True if the Smart Array 5i Controller is found in the system
•
HWQ:RAM gte 512
Returns True if the amount of RAM in the hardware discovery file is at least 512
•
HWQ:EFIFw neq "1.10"
Returns True if the EFI Firmware version in the hardware discovery file is not 1.10
•
HWQ:SystemName eq "Server rx4640"
True if the system name in the hardware discovery file exactly matches "Server rx4640”
•
"PCI:Smart Array 6402" or "PCI:Smart Array 6404"
True if the system contains a Smart Array 6402 Controller or a Smart Array 6404 Controller
