Using HWQUERY
HWQUERY is used from a script, in conjunction with other utilities, to control the deployment. The
HWQUERY utility enables you to use data from the hardware discovery file in your own scripts.
HWQUERY cannot alter environment variables directly. To set the variable, the output of HWQUERY
must be used by the hosting script. The most common way to use it is to write the output to an
intermediate script that is subsequently called by the hosting script.
HWQUERY command-line syntax
hwquery [path]hpdiscoveryfilename [path]allboards.xml variable=<string> ...
HWQUERY 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."
In this argument, variable is the name of an environment
variable and <string> is a PCI device name or the name variable=
of an element from the hardware discovery file. Arguments
must be in quotes if <string> contains spaces. <string> is
case-sensitive.
You can specify multiple variable=<string> arguments. ...
