New Features in AutoFS
This section discusses the new features that AutoFS supports on systems
running HP-UX 11i v3.
• LDAP Support
AutoFS supports LDAP directories for AutoFS map storage and
distribution.
• NFSv4 Support
AutoFS supports NFSv4 filesystems.
• Secure NFS Support
AutoFS supports secure NFS filesystems.
• IPv6 Support
AutoFS supports filesystem mounting over IPv6 transports.
NOTE AutoFS also provides the features that were initially supported by the
Enhanced AutoFS product.
• On-demand mounting of hierarchical filesystems – AutoFS
mounts only those filesystems that users access. Other filesystems
that are hierarchically related to these filesystems are mounted only
when requested. This prevents unnecessary mounting and
unmounting (mount storms), and improves performance.
• Browsability – AutoFS enables a user to view the directories that
can be mounted for indirect maps, without actually mounting each
filesystem.
• Concurrent mount or unmount – AutoFS performs concurrent
mounts and unmounts, using the multi-threaded automountd
daemon. This prevents services from hanging if a server is
unavailable.
• Reliable NFS ping – AutoFS supports the -retry=n mount option
for an NFS map entry, to configure the ping timeout value.
