The following example shows the root (/) file system restored to the node phys-schost-1 from the tape device /dev/rmt/0. The metaset command is run from another node in the cluster, phys-schost-2, to remove and later add back node phys-schost-1 to the diskset schost-1. All other commands are run from phys-schost-1. A new boot block is created on /dev/rdsk/c0t0d0s0, and three state database replicas are recreated on /dev/rdsk/c0t0d0s4.
