HP StorageWorks Clustered File System 3.1.1 for Linux Installation Guide (May 2006)

Chapter 4: Install HP Clustered File System 26
There are two fencing methods:
• FibreChannel Switch-based fencing. When a server needs to be
fenced, Clustered File System will disable the server’s access in the
FibreChannel fabric. The server must be rebooted to regain access to
the SAN. If you select this method, next go to the Storage
Configuration tab and configure the FC switches. (See “Storage
Configuration” on page 29.)
• Web Management-Based Fencing via Server Reset/Shutdown.
Clustered File System uses remote management hardware on the
server to remove its access to PSFS filesystems. See the HP Clustered
File System QuickSpecs on the HP Web site for a list of supported HP
ProLiant servers. The server must support the HP iLO remote
management functionality.
When you select Web Management Based Fencing via Server Reset/
Shutdown, the Fencing tab will refresh and ask you for configuration
information. Enter the appropriate information for the Remote
Management Controller iLO associated with the server that you used to
connect to the Management Console.
Later in this procedure the complete cluster configuration will be
exported to the other servers that will be in the cluster. During the export,
Clustered File System will, where possible, use the information that you
specified on the Fencing tab to configure Web Management Based
Fencing on the other servers. If a particular entry on the Fencing tab did
not apply to all servers, Clustered File System will ask for that
information for each of the other servers.
CAUTION: If you are using Web Management Based Fencing, the remote
management controller iLO must be configured correctly
before you start Clustered File System on any server. Use the
procedure “Test the Fencing Configuration” on page 36 to
verify that the remote management controller iLO has the
correct information to fence each server.
