Example -- Creating Initial State Database Replicas on a System With Only One Disk

# metadb -a -f -c 3 c0t0d0s3
# metadb
        flags         first blk      block count
     a        u         16              1034            /dev/dsk/c0t0d0s3
     a        u         1050            1034            /dev/dsk/c0t0d0s3
     a        u         2084            1034            /dev/dsk/c0t0d0s3

The system in this example consists of only one disk. (DiskSuite is being installed for its UFS logging feature.) The -a and -f options are used together to create the initial state database replicas. The -c 3 option creates three state database replicas on the same slice on the system's only disk. The metadb command checks that the replicas are active, as indicated by the -a flag.

Use a one-disk configuration for state database replicas as a last resort, as it creates a single point-of-failure.
