Operating System Does Not Boot
If your operating system does not boot, but you are able to reach the BCH (from either the main
disk partition or CD), use the following offline tools to help solve your problem: (See

Troubleshooting Using Online Support Tools
The following online support tools are available from the HP-UX environment.
Support Tools Manager
Support Tools Manager (STM) is available in three user interfaces:
• Graphical interface for X-based terminals (XSTM)
• Menu interface for ASCII terminals (MSTM)
• Command line interface for all ASCII terminals (CSTM)
You can use the graphical and menu interfaces intuitively and you can use the command line
interface to drive STM using scripts.
You can use diagnostics to thoroughly test a device and isolate failures down to the suspected
self-repair unit.
For complete documentation on how to access and use STM go to:
http://www.hp.com.
Under the Topics menu go to Diagnostics and look for Support Tools Manager.
Event Monitoring Service
Event Monitoring Service (EMS) is the framework for monitoring hardware and reporting events.
You can use EMS to eliminate most undetected hardware failures that cause data loss or
interruptions of system operation. You can monitor a hardware device (such as a disk) for the
occurrence of any unusual activity (called an event). When an event occurs, it is reported by a
