Symantec 5 manual Creating I/O fencing configuration files, Deport the coordinator disk group

100Configuring VCS clusters for data integrity Setting up disk-based I/O fencing manually

3Deport the coordinator disk group:

# vxdg deport vxfencoorddg

4Import the disk group with the -toption to avoid automatically importing it when the nodes restart:

# vxdg -t import vxfencoorddg

5Deport 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

1On 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.

2On 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:
