The usedisk keyword can be used when you install either a UFS file system or a ZFS root pool. The usage for this keyword is the same in both UFS and ZFS installations.
For a complete list of keywords that can be used in a UFS or ZFS installation, see Table 8–2
For information on performing a ZFS installation, see Chapter 9, Installing a ZFS Root Pool With JumpStart
usedisk disk_name ... |
By default, the JumpStart program uses all of the operational disks on the system when you specify partitioning default. The usedisk profile keyword designates one or more disks that you want the JumpStart program to use. You must specify disk_name in the form cxtydz or cydz, for example, c0t0d0 or c0d0s0.
If you specify usedisk in a profile, the JumpStart program uses only the disks that you specify after the usedisk keyword.
You cannot specify the usedisk keyword and the dontuse keyword in the same profile.
