4.0.0 HP PolyServe Software for Windows File Serving administration guide (T5392-96047, March 2010)

Setup scenario
The DFS setup procedure uses this scenario:
• A three-node matrix clust[1-3] in the domain data. The two domain controllers
are dc[1-2]. These domain controllers are running Windows 2000 (or higher)
with Active Directory.
• Matrix Server and HP PolyServe Software are installed on nodes clust[1-3] running
Windows 2008 SP2 (64-bit) and Matrix Server is started.
• On the Matrix Server nodes clust[1-3], a shared PSFS volume, y:, is used for DFS
root and another shared PSFS volume, x:, is used for the link.
• All clients needing to access the share foo are either in domain data or in an-
other domain that has a trust relationship with data.
• Clients are either Windows 2000 and higher, Windows 9x with the DFS client
installed, NT4 with the DFS client installed, or other clients as described in Chapter
2.
Considerations for using DFS
When using DFS with HP PolyServe SoftwareHP Clustered File System, you should
be aware of the following:
• We strongly recommend that domain-based DFS be used. Stand-alone DFS does
not provide fault tolerance on root.
• Shares created on a PSFS filesystem and deployed via DFS must be under the
control of Matrix Server. Use only Matrix File Shares; they are designed to work
properly with DFS and HP PolyServe Software. The following should not be used:
• CIFS shares created with other Windows applications. These shares will not
be under HP PolyServe Software control.
• Virtual CIFS Servers. These virtual servers are not compatible with DFS.
• Matrix File Shares must be created before you set up DFS. (See Add a Matrix
File Share, page 10.)
DFS setup
After you have created the appropriate Matrix File Shares, complete the following
steps to set up DFS:
