Example of RAID-1 Volume Disk Layout

The following figure shows a RAID-1 volume that duplicates the root file system (/) over two physical disks. State database replicas (metadbs) are placed on both disks.

Figure 9–2 RAID-1 Volume Disk Layout

Figure 9–2 shows a system with the following configuration.

• The mirror that is named d30 consists of the submirrors that are named d31 and d32. The mirror, d30, duplicates the data in the root (/) file system on both submirrors.

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

• The root (/) file system is copied to the hard disk named hdisk1. This copy is the single-slice concatenation that is named d32.

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