Custom JumpStart and Solaris Live Upgrade Guidelines

The custom JumpStart installation method and Solaris Live Upgrade support a subset of the features that are available in the Solaris Volume Manager software. When you create mirrored file systems with these installation programs, consider the following guidelines.

• The term RAID-0 volume can refer to disk stripes or disk concatenations. The custom JumpStart and Solaris Live Upgrade installation methods only enable you to create single-slice concatenations. You cannot create RAID-0 stripe volumes during the installation or upgrade.

• The custom JumpStart installation method enables you to create up to two submirrors for each mirror. The Solaris Live Upgrade installation method enables you to create up to three submirrors for each mirror. Two submirrors usually provide sufficient data redundancy for most applications, and the disk drive costs are less expensive. Three submirrors enable you to take a submirror offline and perform a backup while maintaining the two remaining submirrors for continued data redundancy.

• If you create mirrored file systems with the custom JumpStart installation method, you do not need to create the file systems that you are mirroring before you create the mirror.
