About OpenBoot Commands

OpenBoot commands are commands you type from the ok prompt. OpenBoot
commands which can provide useful diagnostic information are:

probe-scsi-all

■
■ probe-ide
show-devs
■
probe-scsi-all
The probe-scsi-all command diagnoses problems with the SAS devices.
Caution – If you used the halt command or the Stop-A key sequence to reach the
ok prompt, then issuing the probe-scsi-all command can hang the system.
The probe-scsi-all command communicates with all SAS devices connected to
on-board SAS controllers and accesses devices connected to any host adapters
installed in PCI slots.
For any SAS device that is connected and active, the probe-scsi-all command
displays its loop ID, host adapter, logical unit number, unique World Wide Name
(WWN), and a device description that includes type and manufacturer.
