7.12.2.5 OBP probe-scsi and probe-scsi-all Commands
Todiagnose 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 software as
an alternative method of testing the SCSI interfaces. See Section 7.1 “About
Diagnostic Tools”on page 186 for more information.
The probe-scsi command transmits an inquiry command to all SCSI devices
connected to the main logic board SCSI interfaces. These include 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 back 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.
