I have a SparcStation 10 and it came with an external CD Rom Drive. I am trying to install Solaris 2.6 Server on this machine from the Cd Rom. At the OK> prompt I type "boot cdrom - browser" and I get an error:
scsi device not found:error = -1

or something to that effect. Does anyone have any experience with setting up a 411 type cdrom on a Sparc 10 or may know what I might be doing wrong?

Try: probe-scsi-all

at the ok prompt to see if the cdrom is detected. If not, the cabling may be loose, or the drive may be defective somehow. Also make sure that the scsi ID does not conflict with any other device(s) you may have in the system.

I did a probe-scsi-all and it detects my sony CD-ROM. But when I do a "test cdrom" it returns:
scsi device 6,0 is not responding
cdrom selftest ailed, Return code = - 1
I don't know wat else to do. Unless you somehow have to map the device name CDROM to the scsi device. Beats me....I need some help here.

Your error indicates that the SCSI device is not installed properly. As PxT suggests, it might be a good idea to check the SCSI IDs, the cable, the terminations, etc. Sounds like you have a hardware problem.

I am not familiar enough to even know how to check the SCSI IDs. If anyone can refer me to a book that might cover these type of hardware configuration commands and files, I would appreciate it. Keep in mind...I have only been using UNIX for about 1 week now.

Since the cdrom is external, look on the back of it and there should be some number next to it you should be able to change the number this number is your scsi id. Do you know if you have any other devices that are scsi? If so look at them also to make sure you don't use the same number.

The problem you are describing (and its solution) is not a UNIX problem. It is a SCSI hardware problem. SCSI does-not-equal UNIX, BTW.
