HP StorageWorks Clustered File System 3.6.0 Windows Storage Server Edition Setup Guide (403102-005, January 2008)

Chapter 3: Setting Up HP StorageWorks Clustered File System 18
#Set to 1 to disable creation of permanent mountpoints.
#(default behavior is that scl will create permanent mountpoints
#for all imported devices.)
#
#no_permanent_mountpoints 0
On the last line, remove the # sign preceding
no_permanent_mountpoints and change the value to 1:
no_permanent_mountpoints 1
11. Configure FC Switches
NOTE: For all FC switches, it is best practice to place each HBA port and
its storage ports in a separate zone. No other initiator HBA port
should be present in this zone.
When certain problems occur on a server (for example, hardware
problems or the loss of cluster network communications), and the server
ceases to effectively coordinate and communicate with other servers in
the cluster, HP Clustered File System must remove the server’s access to
filesystems to preserve data integrity. This step is called fencing.
When you configure the cluster later in this procedure, you can select the
fencing method that you want to use:
• FibreChannel Switch-based fencing (also called “fabric fencing”).
When a server needs to be fenced, HP Clustered File System disables
the server’s access in the FibreChannel fabric.
• Web Management-Based Fencing via Server Reset/Shutdown (also
called “server-based fencing”). HP Clustered File System uses remote
management hardware on the server to remove its access to PSFS
filesystems.
For sites using fabric fencing, the FibreChannel switches must be
configured as described below to enable cluster operations across the
SAN.
