Troubleshooting and Diagnostics
6–6 Compaq ES40CSLP Rackmount System Installation/User/Service Guide
6.4 Service Tools and Utilities
The following sections describe some of the tools and utilities available for acceptance testing
and diagnosis and gives recommendations for their use.
6.4.1 Error Handling/Logging Tools (Compaq Ana lyze)
Tru64 UNIX and OpenVMS operating systems provide recovery from errors, fault handling, and
event logging.
The primary tool for error handling is Compaq Analyze, a fault analysis utility designed to
analyze both single error/fault events and multiple events. Compaq Analyze uses error/fault
data sources in addition to the traditional binary error log. See Section 6.7.2 for information on
Compaq Analyze.
6.4.2 ROM-Based Diagnostics (RBDs)
Many ROM-based diagnostics and exercisers execute automatically at power-up. RBDs can be
invoked in console mode using SRM console commands. The remote management console
(RMC) also provides diagnostic commands.
ROM-based diagnostics are the primary means of testing the console environment and
diagnosing the CPU, memory, Ethernet, I/O buses, and SCSI subsystems. Use ROM-based
diagnostics in the acceptance test procedures when you install a system or replace the following
components: CPU module, memory motherboard, system motherboard, I/O bus device, or
storage device. Refer to Section 6.6 for information on running ROM-based diagnostics.
6.4.3 Loopback Tests
Internal and external loopback tests are used to test the components on the miscellaneous I/O
module and to test Ethernet cards. The loopback tests are a subset of the ROM-based
diagnostics.
Use loopback tests to isolate problems with the COM2 serial port, the parallel port, and
Ethernet controllers. Refer to Section 6.6 for instructions on performing loopback tests.
6.4.4 SRM Console Commands
SRM console commands are used on systems running Tru64 UNIX or OpenVMS to set and
examine environment variables and device parameters, as well as to invoke ROM-based
diagnostics and exercisers. For example, the show configuration and show device commands
are used to examine the configuration; the set command is used to set environment variables;
and the test and sys_exer commands are used to test the system.
Use SRM console commands to set and examine environment variables and device parameters
and to run RBDs. Refer to Section 3.4 for information on configuration-related firmware
commands and Section 6.6 for information on running RBDs using SRM commands.
