Sample Layout for Mirrored File Systems

The following figure shows a mirror that duplicates the root file system (/) over two physical disks. State database replicas (metadbs) are placed on both disks.

Figure 10–2 Sample Layout for a Mirrored Root File System

Figure 10–2 shows a system with the following configuration.

• The root file system (/) on hdisk0 is included in the single-slice concatenation that is named d31.

• A single-slice concatenation that is named d32 is created on the hard disk that is named hdisk1.

• The mirror that is named d30 consists of the submirrors that are named d31 and d32.

• The mirror duplicates the data in the root file system on both submirrors.

• State database replicas are created on slices both hdisk0 and hdisk1.

For an example profile that uses the custom JumpStart installation method to create this configuration, see Example 26–10.
