Creating RAID-1 Volumes (Mirrors) With Custom JumpStart

This feature is new in the Solaris 9 4/04 release.

The custom JumpStart^TM installation method now enables you to create RAID-1 volumes (mirrors) during the installation of the Solaris Operating System. By mirroring file systems, you can protect your system by duplicating data over two physical disks. If one of the mirrored disks fails, the system data is still accessible from the second mirrored disk.

In JumpStart, the following new custom profile keywords and values enable you to create mirrored file systems.

• The new filesys keyword value mirror creates a mirror. Then you can designate specific slices as single-slice concatenations to attach to the mirror.

• The new metadb profile keyword enables you to create the required state database replicas.
