Description: How to verify that tape drives, Library and other attached devices are seen within the SCSI card (host bus adapter) on Solaris.
Solaris has a command feature to allows you to see all attached devices. The command is called 'probe'. It is invoked at the low level Solaris OK prompt. This is referred to as OpenBoot. (OpenBoot is not available in Solaris x86 Intel installations)
In order to enter the low level Solaris probe-scsi prompt there is a procedure to follow.
Use the commands:
/usr/sbin/sync;sync;sync;init;halt
/usr/sbin/reboot
then during the reboot I would hold the 'stop' key followed by the 'a' key
or
/usr/sbin/sync;sync;sync;init;reboot
And during the reboot I would hold the stop key followed by the 'a' key.
NOTE the 'stop' key is native to the solaris keyboard.
Use the Sun recommended procedure:
/usr/sbin/shutdown
/sbin/init
/usr/sbin/halt
/usr/sbin/reboot
/usr/sbin/poweroff
Stop+A or L1+A
Once in OpenBoot mode you can enter the following commands to gather information that will verify that the devices that you have physically attached are being seen properly by the host bus adapter and through the PCI slot.
Some commands you can use depending on your devices are;
probe-scsi
Identifies devices attached to the internal SCSI bus.
probe-scsi-all
Identifies devices attached to any SCSI bus.
probe-ide
Identifies IDE devices attached to the PCI bus.
probe-fcal-all
Identifies devices on all fibre channel loops.
reset-all
Resets the entire system, similar to a power cycle. And allows you to reboot the system back to the OS level.
In my past testing I've also used;
probe-pci
Probes each PCI slot.
and
probe -all
Probes everything (time consuming).
