Yesterday I tried to install build39 on a 220R. It's original disk was damaged so we replaced it with a 70G drive. I fired off the OpenSolaris installer which failed to install, since it wanted the drive to be formated. OK, no problem boot cdrom -s at the ok prompt and format from the root prompt. 8hours later the disk was formated and analyzed but the label was not written. Hence, no install!
And here comes the weird solution:
Find a Solaris 8 SPARC cdrom and boot cdrom -s at the ok prompt and format from the root prompt. You do not have to reformat the drive, just label it. Then start with the OpenSolaris (SPARC) CD#1 and you are all set.
Weird and inexplicable to me why something that is possible from the Solaris 8 format is not possible with format from OpenSolaris.
If anybody has an explanation, please please post it. I like it that it works. I do not like it that I do not know why it works.
