Can HAD start without I/O fencing?

[Abhishekjha]

I want to remove I/O fencing completely and start VCS (in test environment), but every time I fire hastart command, HAD tries to start I/O fencing driver and fails to start HAD. I have removed the registered key, disabled fencing in /etc/vxfenmode file and rebooted the system couple of times but couldn't start HAD.

Please advise.

OS- Solaris 10

VCS 5.1

Thanks,

Just stop VCS (hastop -all), remove "UseFence = SCSI3" line from main.cf and restart VCS.

Hi, 

try:

1.hastop -all

 Make a backup copy of the main.cf file:
# cd /etc/VRTSvcs/conf/config
# cp main.cf main.orig
2 On one node, use vi or another text editor to edit the main.cf file. To modify
the list of cluster attributes, remove the UseFence attribute .
cluster clus1(
UserNames = { admin = "cDRpdxPmHpzS." }
Administrators = { admin }
HacliUserLevel = COMMANDROOT
CounterInterval = 5
UseFence = SCSI3  <<<
)
3.Save and close the file.
4. Verify the syntax of the file /etc/VRTSvcs/conf/config/main.cf:
# hacf -verify /etc/VRTSvcs/conf/config

5 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

6. hastart on each node.
