The host type creates the context and subcontexts for a single host. The command automatically creates a service context for the host and a binding for fs unless the -o option is used. When the -o option is used, only the host context is created.
# fncreate -t host org/sales/host/antares/
creates a context for the host named antares and effectively runs the commands
fncreate -t service org/sales/host/antares/service/ fncreate -t fs org/sales/host/antares/fs/
The hostname context (org/sales/host in the above example) to which the machine belongs must already exist. The machine name supplied should already exist in the NIS+ hosts.org_dir table.
