NetWare volumes can span multiple drives. When a volume spans more
than one drive, all of the drives that it spans must be shared or all of
them must be not shared. Otherwise if one drive fails, there will be no
access to the volume from either cluster server.

NHAS cluster server will function within different containers in the
NDS tree, but they must reside in the same directory tree to ensure
smoother failover of NDS resource objects.
■
It is not necessary for servers in the cluster to contain NDS replicas as
long as multiple trusted replicas exist on the network. If one server in
the cluster contains a trusted NDS replica, then for NDS availability
reasons, both servers should contain a replica.
