HPDISCOVERY command-line examples
Command-line argument Description
hpdiscovery -f
/toolkit/hpdiscovery.xml
This command generates the file hpdiscovery.xml in the

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
Command-line argument Description

into device names, such as "Smart Array 5i Controller."
This argument specifies the query expression. See
"Expression operators and terms (on page
