Software Commands
System software provides Solaris and OBP commands that you can use to diagnose problems. For more information on Solaris commands, see the appropriate man pages. For additional information on OBP commands, see the OpenBoot 3.x Command Reference Manual. (An online version of the manual is included with the Solaris System Administrator AnswerBook that ships with Solaris software.)
Solaris prtdiag Command
The prtdiag command is a UNIX shell command used to display system configuration and diagnostic information. You can use the prtdiag command to display:
-
System configuration, including information about clock frequencies, CPUs, memory, and I/O card types
-
Diagnostic information
-
Failed field-replaceable units (FRUs)
% /usr/platform/sun4u/sbin/prtdiag
To isolate an intermittent failure, it may be helpful to maintain a prtdiag history log. Use prtdiag with the -l (log) option to send output to a log file in /var/adm.
Note -
Refer to the prtdiag man page for additional information.
An example of prtdiag output follows. The exact format of prtdiag output depends on which version of the Solaris operating environment is running on your system.

OBP show-devs Command
If you are working from the OBP prompt (ok), you can use the OBP show-devs command to list the devices in the system configuration.
OBP printenv Command
Use the OBP printenv command to display the OpenBoot PROM configuration variables stored in the system NVRAM. The display includes the current values for these variables as well as the default values.
OBP probe-scsi and probe-scsi-all Commands
To diagnose problems with the SCSI subsystem, you can use the OBP probe-scsi and probe-scsi-all commands. Both commands require that you halt the system.
Note -
When it is not practical to halt the system, you can use SunVTS as an alternate method of testing the SCSI interfaces. See "About Diagnostic Tools" for more information.
The probe-scsi command transmits an inquiry command to all SCSI devices connected to the main logic board SCSI interfaces. This includes any tape or CD-ROM drive in the removable media assembly (RMA), any internal disk drive, and any device connected to the external SCSI connector on the system rear panel. For any SCSI device that is connected and active, its target address, unit number, device type, and manufacturer name are displayed.
The probe-scsi-all command transmits an inquiry command to all SCSI devices connected to the system SCSI host adapters, including any host adapters installed in PCI slots. The first identifier listed in the display is the SCSI host adapter address in the system device tree followed by the SCSI device identification data.
The first example that follows shows a probe-scsi output message. The second example shows a probe-scsi-all output message.
