Operator or term Result
and
True if both operands are true
or
True if either operand is true
gt
True if the first operand is greater than the second

PCI:<string>
True if a PCI device whose name includes <string> is found in the hardware discovery
file. <string> is case-sensitive.
HWQ:<string>
The hardware discovery file is searched for <string>, and the corresponding value is
the value of this term. <string> is case-sensitive.

Expression input
Result
"PCI:Smart Array 5i"
True if the Smart Array 5i Controller is found in the
system
HWQ:TotalRAM gte 512
True if the amount of RAM in the hardware
discovery file is at least 512
HWQ:ROMDate neq "11/12/2004"
True if the ROM date in the hardware discovery file
is not 11/12/2004
HWQ:SystemName eq "ProLiant DL380 G2"
True if the system name in the hardware discovery
file exactly matches "ProLiant DL380 G2"
HWQ:SystemName eq "ProLiant DL380 G2" and
"PCI:Smart Array 5i" and HWQ:ROMDate eq
"11/12/2004"
True if the system is a ProLiant DL380 G2 with a
Smart Array 5i Controller present and a ROM date
of 11/12/2004
"PCI:Smart Array 5i" or "PCI:Smart Array
6i"
True if the system contains a Smart Array 5i
Controller or a Smart Array 6i Controller
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.
