The probe-scsi and probe-scsi-all Commands

The OpenBoot PROM commands probe-scsiand probe-scsi-allreport information about SCSI devices on the server that are active and connected. To run either command, type it at the ok prompt.

The probe-scsicommand transmits an inquiry command to internal and external FC-AL and SCSI devices connected to the system on-board SCSI or FC-AL interface. If a device is connected and active, the target address, unit number, device type, and manufacturer name are displayed.

The probe-scsi-allcommand transmits an inquiry command to all devices connected to the system. The first identifier listed in the display is the SCSI host adapter address in the system device tree, and is followed by the SCSI device identification data.

About Exercising the System

It is relatively easy to detect when a system component fails outright. However, when a system has an intermittent problem or seems to be “behaving strangely,” a software tool that stresses or exercises the computer’s many subsystems can help disclose the source of the emerging problem and prevent long periods of reduced functionality or system downtime.

Sun provides a standard tool for exercising its desktop and server systems: the Sun Validation Test Suite (SunVTS).

About Exercising the System Using SunVTS Software

SunVTS is a comprehensive software diagnostic package that tests and validates Sun hardware by verifying the connectivity and functionality of most hardware controllers, devices, and platforms. Use SunVTS software as part of troubleshooting, periodic maintenance, and system or subsystem stress testing.
