I/O fencing configuration files (continued)
DescriptionFile
This file contains the following parameters:
■ vxfen_mode
■ scsi3—For disk-based fencing
■ customized—For server-based fencing
■ disabled—To run the I/O fencing driver but not do any fencing operations.
■ vxfen_mechanism
This parameter is applicable only for server-based fencing. Set the value as cps.
■ scsi3_disk_policy
You must configure the vxfen module to use DMP devices or iSCSI devices, and set the SCSI-3
disk policy as dmp.
■ security
This parameter is applicable only for server-based fencing.
1—Indicates that Symantec Product Authentication Service is used for CP server
communications. This setting is the default.
0—Indicates that communication with the CP server is in non-secure mode.
Note: The CP server and the Storage Foundation Cluster File System clusters must have
the same security setting.
■ List of coordination points
This list is required only for server-based fencing configuration.
Coordination points in a server-based fencing can include coordinator disks, CP servers, or
a mix of both. If you use coordinator disks, you must create a coordinator disk group with
the coordinator disk names.
Refer to the sample file /etc/vxfen.d/vxfenmode_cps for more information on how to specify
the coordination points.
■ single_cp
This parameter is applicable only for server-based fencing which uses a single highly available
CP server as its coordination point.
