32 UPSUTIL for MPE/iX
Introduction
UPSUTIL is an easy-to-use support tool that helps to manage the UPS Monitor/iX UPS-management
subsystem on MPE/iX HP e3000 systems.
Working in conjunction with the system’s UPS Monitor/iX UPS management subsystem, UPSUTIL provides
easily accessible functions that assist authorized users to:
• Check the system to see if the UPS Monitor/iX subsystem is running.
• Check the system to see what, if any, UPS LDEVS (logical devices) has been configured.
• Check the current operational status of all configured UPS devices on the system.
• Control (start, stop, restart, set UPS Monitor configuration file) the UPS Monitor/iX subsystem while the
HP e3000 system is running.
These functions make it easy to determine whether the running system has been configured correctly for UPS
devices, whether the UPS Monitor/iX subsystem is communicating correctly with the configured UPS devices,
and allow an online user to have “stop and start” control over the UPS Monitor/iX subsystem.
The “stop and start” control is valuable in cases where a UPS device may have been removed from the system
for repair and is now being reinstalled in the system, or has had its I/O interface cable accidentally or
intentionally disconnected and now reconnected. In either of these cases, without UPSUTIL it is necessary to
re-boot the system in order to re-start the monitoring of that UPS device by the UPS Monitor/iX subsystem.
But with UPSUTIL, the UPS Monitor process may be restarted with the system up, without rebooting the
system. This ability reduces system downtime and increases system availability.
Intended Users
UPSUTIL is intended to be used by authorized system users who perform system management functions for
the HP e3000 system, such as:
• System Managers
• System Operators
• HP Customer Engineers
• HP Response Center Engineers
UPSUTIL is not intended for use by “ordinary” system users.
(Refer to the “Product Invocation and Security” section of this document for information about limiting usage
of UPSUTIL.)
Product Environment
UPSUTIL is intended for and supported for use in an HP e3000 MPE/iX system environment, characterized
as follows.
Hardware Environment
UPSUTIL will run correctly on any HP e3000 system platform, but is intended for, and really only useful on,
HP e3000 systems that employ the UPS method of power failure protection, such as:
