Workflow to configure I/O fencing
Initialize disks as VxVM disks
Check disks for I/O fencing
compliance
Manually configure disk-based I/O
fencing
Preparatory tasks
vxdiskadm or vxdisksetup utilities
vxfenadm and vxfentsthdw utilities
Configure
disk-based fencing
(scsi3 mode)
Configure
server-based fencing
(customized mode)
Configuration tasks
Use one of the following methods
Install and configure VCS or SFHA on CP server
systems
Manually configure server-based I/O fencing
Preparatory tasks
Identify an existing CP server
Configuration tasks
Use one of the following methods
If the CP server is clustered, set up shared
storage for the CP server
Run the configure_cps utility and follow the
prompts (or) Manually configure CP server
