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 return codes

Value
0

Result
True if the Smart Array 5i Controller is found in the system
True if the amount of RAM in the hardware discovery file
is at least 512
True if the ROM date in the hardware discovery file is not
1 1/12/2004
True if the system name in the hardware discovery file
exactly matches "ProLiant DL380 G2"
True if the system is a ProLiant DL380 G2 with a Smart
Array 5i Controller present and a ROM date of
1 1/12/2004
True if the system contains a Smart Array 5i Controller or
a Smart Array 6i Controller
Description
This argument specifies the hardware discovery file used
to run the query.
This argument specifies the allboards.xml PCI device list
file, which is used to convert PCI IDs found in hardware
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
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.
Meaning
The command was completed successfully.
N arguments were ignored because they were not in the
variable=<string> format.
