HP UPS Management Module web interface 70
2. Enter the device name or description in the Description field.
3. Select the type of device in the Type dropdown box:
o Remote Agent—Select Remote Agent when attaching a network agent to the UPS.
o Serial Agent—Select Serial Agent when attaching a serial agent to the UPS.
o Storage Device—Select Storage Device when attaching a shared hard disk storage device to a
UPS load segment. Storage devices have the longest runtime so servers accessing this device can
save data before shutting down.
o Other Device—Select Other Device for any unmanaged device, such as a router or hub.
Unmanaged devices are either on or off and are not shut down gracefully.
4. If output power is supplied by controllable load segments, select the load segment to which the
device is attached in the Load dropdown box. Depending on your UPS model, the number of
available load segments varies.
5. If the device type is Remote Agent, enter the IP address of the machine that hosts the agent in the IP
Address field.
-or-
If the device type is Serial Agent, select the serial connector on the management module to which the
agent is connected in the Management Module Serial Port dropdown box.
6. To configure the command procedure SDScript to run at shut down:
a. Select the Run Command Procedure (SDScript)? checkbox.
b. Edit the SDScript file or create a new SDScript file. A sample SDScript file is landed in the root
folder for every agent. The name of the SDScript file must be SDScript.CMD, and this file must
remain in the root folder.
IMPORTANT: SDScript command execution can be a very powerful tool and should be tested
thoroughly before being used for the first time in response to a power event. Not all programs
and applications are suitable to be executed as a process, especially programs that do not
create their own environments. Command execution behavior varies by operating system, and,
in general, commands to be executed should be put into a batch file or shell script depending
on the operating system that will be executing the commands. Using an SDScript gives you
more control over the circumstances in which commands are executed and allows the
commands to run in a copy of the environment.
When selecting commands to be executed in the SDScript file, choose programs and processes
that do not require user input or interaction. Since the commands can be executed at any time,
it is difficult to predict if a user will be available to interact with any programs that are
launched. Verify that specified drive mappings, user specific directories, and programs that
require special rights are accessible by the SDScript file.
Most operating systems have a method for spawning new processes. In Windows operating
systems, commands can be preceded with START, and in most Linux/Unix systems, sh can be
used. When designing your SDScript file, determine which commands require a separate
process and which commands can be run one after another in the same process. Refer to the
documentation that came with your operating system for more information on batch files or
script files.
NOTE: An SDScript cannot be run on a server unless the server has an agent installed. The
SDScript file must reside on the server on which the command will be executed.
