Hello, I had the same problem yesterday....
After the jumpstart stops, I checked my disk with format and think I deleted all fdisk partitions... Or/and was it the modify of my profile on the jumpstart server? have a look at the line fdisk..... Then I restartet /sbin/install-solaris and after a few tries the automated jumpstart goes on ;-) Tomorroy I've done another run and it work's. Good Luck Hans Foertsch PS: I can give to you my profile (from the last run), but at the moment I can't access it. -- This message posted from opensolaris.org
