vxfen_mode - sets the main operation mode of I/O Fencing FORMAT: vxfen_mode=[scsi3|customized|disabled]vxfen_mechanism - specifies which mechanism of customized fencing is to be used by I/O Fencing. If the vxfen_mode is customized, a valid vxfen_mechanism is mandatory. NOTE: The customized mechanism is only supported in certain configurations. It is not available for customers to write their own fencing mechanism. FORMAT: vxfen_mechanism=[sanvm|<user_defined>]
- use scsi3 persistent reservation disks
- use script based customized fencing (support for this is limited!)
- run the driver but don't do any actual fencingvxfen_script_timeout - determines the time vxfend should wait for customized fencing scripts to finish execution before attempting to manually shut them down. If this option is omitted, the default value is 120 seconds. This parameter is only used when running vxfen_mode=customized FORMAT: vxfen_script_timeout=[<user_defined>]
- use sanvm for cluster membership coordination
- use a customized fencing mechanism created by the end-user (not supported at this time)scsi3_disk_policy - determines the way in which I/O Fencing communicates with the coordination disks FORMAT: scsi3_disk_policy=[raw|dmp]
- time to wait for customized fencing scripts before shutting them down
- connect to disks using the native interface
- use dynamic multipathing
# vxfen configuration file for SCSI3 vxfen_mode=scsi3 scsi3_disk_policy=dmpThe following example shows a typical /etc/vxfenmode file configuring I/O Fencing to run in customized mode, sanvm mechanism and script timeout value of 10 minutes.
# vxfen configuration file for SANVM vxfen_mode=customized vxfen_mechanism=sanvm vxfen_script_timeout=600
