4 Troubleshooting
This chapter describes diagnostic and troubleshooting tools for Smart Array Series Controllers.
NOTE:
Command outputs are similar for different Smart Array SAS controllers, so in most cases
the example output is shown for only one controller model. If the difference between controllers is
significant for a specific command, separate examples from each controller type are provided.
HP Support Tools Manager
HP STM is a software application you can run from the console to obtain status and descriptive
information about HP Smart Array Controllers. You can also use STM to diagnose problems.
You must use STM C.46.00 or later with Smart Array Controllers on HP-UX 11i v2 (September
2004) or later.
For more information about STM and other diagnostic tools, see the HP website at www.hp.com/
go/hpux-core-docs.
Event Monitoring Service
EMS notifies you when an event occurs on the system.
A hardware event monitor monitors hardware for unusual behavior (an event) and sends a message
to EMS, which notifies you of the event and provides suggestions for correcting the problem. EMS
is available for the Smart Array Controller.
For more information about how hardware monitors work, see the HP website at www.hp.com/
go/hpux-core-docs.
Offline Diagnostics Environment
ODE supports Smart Array Controllers. ODE is an offline support tool for troubleshooting systems
that are running without an operating system or systems that cannot be tested using online tools.
The offline environment is also useful for testing a system before it boots.
ODE provides a user-friendly interface for diagnostics and utilities developed to run in this
environment. ODE has a distributed architecture consisting of several modules. Each module has
a specific function and uses well defined protocols to communicate with the other modules.
You can use ODE with a command line interface or a menu interface. Use the command line
interface to select specific tests and utilities to perform on a specific hardware module.
Use the menu-driven interface to specify the hardware module to be tested. It automatically selects
and performs the necessary tests.
ODE consists of:
•
A test controller, which acts as the user interface and launches the execution of test modules.
•
Test modules, which consist of diagnostic or utility programs that execute in ODE. These
modules exercise or diagnose user specified hardware units.
•
A system library (SysLib), which consists of a set of common routines for use by the test controller
and test modules. These routines perform I/O, string parsing, and system control.
For more information about ODE, see the HP website at www.hp.com/go/hpux-core-docs.
PCI Error Recovery
The PCI Error Recovery feature provides the ability to detect, isolate, and recover from a PCI error,
avoiding a system crash. PCI Error Recovery is included with the HP-UX 11i v2 and 11i v3 operating
systems, and is enabled by default.
