Red Hat Knowledgebase

The Vixel Fibre Channel switch accepts telnet connections from the Red Hat Enterprise Linux 3 GFS fence_vixel I/O fencing agent.

To properly isolate and prevent the failed GFS node from causing data corruption to the shared storage, fence_vixel removes the zone access of the node's port to the other ports of the storage.

Once the failed GFS node is ready to join the GFS cluster the port on the Vixel Fibre Channel needs to be enabled. This can be done by accessing the switch via telnet:

telnet ip_address 

Note: change ip_address to the switch's IP address

In Vixel's Root Menu, type the command below:

config zone config 1 2,3,4

The example above will enable communications between port 1 and ports 2,3 and 4. It will also disable communication of the said ports to the other unnamed available ports.

Consult Vixel for further details on zoning configuration.
