dontuse disk_name [disk_name...]

dontuse designates one or more disks that you don't want the Solaris installation program to use when partitioning default is specified (by default, the installation program uses all the operational disks on the system). disk_name must be specified in the form cxtydz or cydz, for example, c0t0d0.

You cannot specify the dontuse keyword and the usedisk keyword in the same profile.
