probe-scsi Command

The probe-scsi command is used to diagnose problems with SCSI devices.
Caution – If you used the halt command or the Stop-A key sequence to reach the
ok prompt, then issuing the probe-scsi command can hang the system.
The probe-scsi command communicates with all SCSI devices connected to on-
board SCSI controllers.
For any SCSI device that is connected and active, the probe-scsi command
displays its loop ID, host adapter, logical unit number, unique World Wide Name
(WWN), and a device description that includes type and manufacturer.
The following is sample output from the probe-scsi command.
