fdisk partitions sometimes fail?
There is a well known bug that sometimes prevents Solaris from installing into an existing partition. Its cause has never been identified, or its existence officially acknowledged by filling out a bug report. It is secretly well known only to Sun’s Installation Support team in Chelmsford, MA., who claim that the workaround is apparent from the message “slice extends beyond end of disk”. I agree that the workaround is simple, but I think some kind of document explaining the workaround should be returned by searches of sunsolve and access1. Better yet, the error message could actually describe the error!
