HP CIFS Client A.02.02 Administrator's Guide

Introduction to the HP CIFS Client
HP CIFS Client Features
Chapter 120
For information on how to set up DFS on a CIFS server, consult your
CIFS server documentation.
The following describe the major features of DFS:
• High data availability
Multiple copies of read-only shares can be mounted under the same
logical DFS name to provide alternate locations for accessing data. If
one of the copies becomes unavailable, an alternate is automatically
selected.
• Load balancing
Multiple copies of read-only shares on separate disk drivers or
servers can be mounted under the same logical DFS name, thus
permitting limited load balancing between drives or servers.
• Name and location transparency
DFS transparently links server volumes and shares into a single
name space. You can navigate the logical name space without
consideration to the physical location of your data.
• Integration with Windows NT security model
There are no additional administrative or security issues. Users who
connect to DFS shares are only permitted to access files for which
they have appropriate rights on that share.
Limitations
CIFS Client MS DFS support has the following limitations:
• Moving files across DFS links is not supported.
• Before the CIFS Client connects to a DFS Root on an HP CIFS
Server (Samba), CIFS UNIX Extensions must be disabled on either
the CIFS Client or Server.
Dynamically Loadable Kernel Module
The kernel component of the HP CIFS Client is implemented as a
Dynamically Loadable Kernel Module (DLKM). Both static binding and
dynamic loading are supported. Dynamic loading can be demand-loading
or auto-loading. With DLKM support, installation, removal, and update
of the HP CIFS Client do not require a system reboot.
