The only case where Solaris needs a disk to be zeroed is
where an IDE disk has been installed on a system/OS version
which does not support large drives. In this case only the
boot block needs to be zeroed.
This was a common issue with the Ultra5/10 when a user installed
a large disk which was not correctly recognised.
