Goal

Bug 4700505 was a request to implement a probe-ide command on the v1280 so as to list the devices connected to the IDE bus. For the Sun Fire[TM] V1280 (and E2900) this means probing for a single device, a DVD-ROM drive, at the ok prompt. However, the bug was closed as "Will Not Fix" as the DVD-ROM drive can be seen during POST. From time to time, a probe-ide command would be very useful for troubleshooting IDE problems. This document suggests a way to simulate the probe-ide command.

probe-ide does not exist on Sun Fire [TM] V1280/E2900, Netra 1280/1290 Systems

Solution

There are two approaches to this problem. The first is to run commands directly from the ok prompt. However, these commands are lengthy and difficult to remember because they include the path address of the IDE bus. And you will need to remember more than one path address depending on whether you are working with PCI+ or standard PCI. Nevertheless, from time to time you might want to quickly probe the IDE bus and in such cases a direct approach will be quicker. The commands are as follows:

For PCI Based Systems:

 {0} ok apply show-children /ssm@0,0/pci@18,700000/ide@3

     Device 0  ( Primary Master )
Removable ATAPI Model: TOSHIBA DVD-ROM SD-C2612

     Device 1  ( Primary Slave )
Not Present

For PCI+ Based Systems:

 {0} ok apply show-children /ssm@0,0/pci@18,700000/pci@4/ide@2

     Device 0  ( Primary Master )
Removable ATAPI Model: TOSHIBA DVD-ROM SD-C2612

     Device 1  ( Primary Slave )
Not Present

     Device 2  ( Secondary Master )
Not Present

     Device 3  ( Secondary Slave )
Not Present

nvramrc script:

If you need to probe the IDE bus on a regular basis, an nvramrc script might be a better option than the above commands. You will need two different scripts, one for PCI based systems, and one for PCI+/PCI-X based systems as follows...

For PCI Based Systems:

Become familiar with nvramrc editing commands and use nvedit to enter the following lines into the edit buffer taking care to insert the spaces around quote marks where necessary:

{0} ok nvedit

   0: \ ...........probe-ide command for LW8s Only..........
1: probe-all
2: install-console
3: : probe-ide ( -- )
4: ." /ssm@0,0/pci@18,700000/ide@3: " cr
5: " /ssm@0,0/pci@18,700000/ide@3" " show-children" execute-device-method cr
6: ;
7: banner
8: \ .....................................................
9: ^C

Before implementing this nvramrc script (before invoking nvstore and setting use-nvramrc? to true) use nvrun followed by probe-ide to test the script that's currently in the edit buffer. If you don't, and there is a typo in the script, you might not be able to reach the ok prompt to re-run nvedit and correct the mistake. A setdefaults will be required from the lom prompt to recover. Once you are happy that the script works as desired, go ahead and set use-nvramrc? to true and reset-all.

{0} ok nvrun

  /ssm@0,0/pci@18,700000/ide@3:
Device 0  ( Primary Master )
Removable ATAPI Model: TOSHIBA DVD-ROM SD-C2612

    Device 1  ( Primary Slave )
Not Present

{0} ok nvstore

{0} ok setenv use-nvramrc? true

{0} ok reset-all

You should now have a probe-ide command:

{0} ok probe-ide

  /ssm@0,0/pci@18,700000/ide@3:
Device 0  ( Primary Master )
Removable ATAPI Model: TOSHIBA DVD-ROM SD-C2612

   Device 1  ( Primary Slave )
Not Present

Remember that the above script is targeted at a specific IDE Bus and so cannot be regarded as a true probe-ide script. However, in this case it targets the only IDE Bus in the system and suits the purposes of listing the peripheral devices on that bus.

For PCI+ Based Systems:

Edit lines 4 and 5 in the above script and change the path address to the following...

 /ssm@0,0/pci@18,700000/pci@4/ide@2

Only change the address in lines 4 and 5. Everything else stays the same.

Then follow the same procedure as above for PCI.
