HP Scripting Toolkit for Linux 9.60 - Manual (Page 28)

Using IFHW
IFHW is used from a script file, in conjunction with other utilities, to control the deployment. The
IFHW utility enables you to make 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 return code
of the tool, which the hosting script can use to conditionally perform actions.
IFHW command-line syntax
ifhw [path]hpdiscoveryfilename [path]allboards.xml <expression>
IFHW command-line arguments
Description Command-line argument
This argument specifies the hardware discovery file used
to run the query. [path]hpdiscoveryfilename
This argument specifies the allboards.xml PCI device
list file, which is used to convert PCI IDs found in hardware [path]allboards.xml
discovery into device names, such as "Smart Array 5i
Controller."
This argument specifies the query expression. See
“Expression operators and terms” (page 28) .
