Chapter 3: Configure Cluster File Shares 14
Considerations for Using DFS
When using DFS with HP 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 HP Clustered File System. Use only Cluster File
Shares; they are designed to work properly with DFS and FS Option
for Windows. The following should not be used:
– CIFS shares created with other Windows applications. These
shares will not be under FS Option for Windows control.
– Virtual CIFS Servers. These virtual servers are not compatible with
DFS.
• Cluster File Shares must be created before you set up DFS. (See “Add a
Cluster File Share” on page 9.)
DFS Setup
NOTE: This section applies to Windows 2003 for HP Clustered File
System (software-only) and Windows Storage Server 2003 for HP
Clustered Gateway (server/software bundle).
After you have created the appropriate Cluster File Shares, complete the
following steps to set up DFS:
1. Open the DFS MMC snap-in under “Administrative Tools.” Create a
“domain-based” DFS root, dfsroot, in Active Directory. A DFS root
target can be on a PSFS filesystem; however, it must be a different
path/share than the link. (When creating the root, you will need to use
drive letters; attempts to use mount points will fail.) Then create “root
targets” pointing to a CIFS share (for example, Y:\dfsroot shared as
\\clust1-3\dfsroot). Each server should have a target pointing to the
same location on the PSFS filesystem.
2. Add a “New Link” called foo. Then add \\clust1\foo1, \\clust2\foo1,
and \\clust3\foo1 as link targets.
