Table 2-2 shows requirements for GFS nodes
that are to be connected to a Fibre Channel SAN.
Requirement
Description
HBA (Host Bus Adapter)
One HBA minimum per GFS node
Connection method
Fibre Channel switch
Note: If an FC switch is
used for fencing, you may want to consider using
Brocade, McData, or Vixel FC switches, for which Red Hat Cluster Suite
fencing agents exist. Refer to Red Hat Cluster Suite Configuring and Managing a Cluster for more information
about supported fencing agents.
Note: When a small number of
nodes is used, it may be possible to connect the nodes
directly to ports on the storage device.
Note: FC drivers may not work
reliably with FC hubs.
