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 HA 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.
