HP StorageWorks Clustered File System 3.6.0 Windows Storage Server Edition Installation Guide (418975-003, January 2008)

Chapter 2: Configuration Information 12
“Administrative Considerations” in Chapter 3 for information about SAN
restrictions.
NOTE: You can attach a cluster server to other SANs that are not under
HP Clustered File System control. These SANs can include tape
drives and non-PSFS filesystems. You can use Windows utilities or
other applications to access these devices and filesystems.
Requirements for Active Directory
HP Clustered File System requires that Active Directory be configured.
You should be aware of the following:
• With Windows 2003, all HP Clustered File System nodes must be
members of an Active Directory domain. This is necessary for
filesystem security.
• Active Directory user and groups should be used in filesystem ACLs.
Do not use local users and groups because they are meaningless to
other nodes in the cluster.
• HP Clustered File System nodes should not be used as domain
controllers because the two services will compete for resources,
resulting in decreased performance.
• The DNS servers used by Active Directory and HP Clustered File
System should not reside on HP Clustered File System nodes. Placing
the DNS servers on HP Clustered File System nodes creates a race
condition that prevents HP Clustered File System from starting.
