Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

Make a backup copy of the main.cf file:

# cd /etc/VRTSvcs/conf/config

# cp main.cf main.orig

On one node, use vi or another text editor to edit the main.cf file. To modify

the list of cluster attributes, add the UseFence attribute and assign its value

as SCSI3.

cluster clus1(

UserNames = { admin = "cDRpdxPmHpzS." }

Administrators = { admin }

HacliUserLevel = COMMANDROOT

CounterInterval = 5

UseFence = SCSI3

)

Regardless of whether the fencing configuration is disk-based or server-based,

the value of the cluster-level attribute UseFence is set to SCSI3.

Save and close the file.

Verify the syntax of the file /etc/VRTSvcs/conf/config/main.cf:

# hacf -verify /etc/VRTSvcs/conf/config

Using rcp or another utility, copy the VCS configuration file from a node (for

example, galaxy) to the remaining cluster nodes.

For example, on each remaining node, enter:

# rcp galaxy:/etc/VRTSvcs/conf/config/main.cf \

/etc/VRTSvcs/conf/config

Start the I/O fencing driver and VCS. Perform the following steps on each

node:

■ Start the I/O fencing driver.

The vxfen startup script also invokes the vxfenconfig command, which

configures the vxfen driver to start and use the coordination points that

are listed in /etc/vxfentab.

# /sbin/init.d/vxfen start

■ Start VCS.

# /opt/VRTS/bin/hastart
