4.6.4 Probe-SCSI and Probe-SCSI-All Diagnostic

The probe-SCSI diagnostic transmits an inquiry command to internal and external

SCSI devices connected to the system unit on-board SCSI interface. If the SCSI

device is connected and active, the target address, unit number, device type, and

manufacturer name is displayed. The probe-SCSI-all diagnostic transmits an inquiry

command to SCSI devices connected to the system SCSI host adapters. 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 probe-SCSI diagnostic is initialized by typing the probe-scsi command at the

ok prompt and the probe-SCSI-all diagnostic is initialized by typing the

probe-scsi-all command at the ok prompt. The following code example

identifies the probe-SCSI diagnostic output message.

CODE EXAMPLE 4-5 identifies the

probe-SCSI-all diagnostic output message.

Type any key to stop.
