Symantec Veritas Cluster Server - Creating I;O Fencing Configuration Files

3
Deport the coordinator disk group:
# vxdg deport vxfencoorddg
4
Import the disk group with the -t option to avoid automatically importing it
when the nodes restart:
# vxdg -t import vxfencoorddg
5
Deport the disk group. Deporting the disk group prevents the coordinator
disks from serving other purposes:
# vxdg deport vxfencoorddg
Creating I/O fencing configuration files
After you set up the coordinator disk group, you must do the following to configure
I/O fencing:
■ Create the I/O fencing configuration file /etc/vxfendg
■ Update the I/O fencing configuration file /etc/vxfenmode
To update the I/O fencing files and start I/O fencing
1
On each nodes, type:
# echo "vxfencoorddg" > /etc/vxfendg
Do not use spaces between the quotes in the "vxfencoorddg" text.
This command creates the /etc/vxfendg file, which includes the name of the
coordinator disk group.

On all cluster nodes depending on the SCSI-3 mechanism, type one of the
following selections:
■ For DMP configuration:
# cp /etc/vxfen.d/vxfenmode_scsi3_dmp /etc/vxfenmode
■ For raw device configuration:
