Cluster SAN Configuration Guidelines
Following are guidelines for configuring the cluster SAN to be used with
Clustered File System:
• The FibreChannel fabric used for a Clustered File System can be
shared with other HP Clustered File Systems clusters or with non-
cluster servers and devices. To protect the cluster SAN devices from
other devices on the fabric, particularly devices controlled by
Windows platforms, we recommend that you create a fabric zone for
the cluster.
• The FC switches managed by the cluster must be from the same
vendor. Switches that will not be managed by Clustered File System
can be from other vendors only if all of the vendors have approved the
configuration.
• To eliminate single points of failure, configure the SAN to use
multipath I/O. See the HP Clustered File System Administration Guide for
some sample cluster configurations that include this feature.
• Disk Power Management must be disabled on any Windows systems
that have access to the SAN storage.
NOTE: You can attach a cluster server to other SANs that are not under
Clustered File System control. These SANs can include tape drives
and non-PSFS filesystems. You can use Linux utilities or other
applications to access these devices and filesystems.
