When I/O fencing is configured in customized mode and the vxfen_mechanism value is set to cps, the recommended way of reading keys from the coordination points (coordinator disks and CP servers) is as follows:
For coordinator disks, the disks can be put in a file and then information about them supplied to the vxfenadm command.
# vxfenadm -s all -f file_name
For CP servers, the cpsadm command can be used to obtain the membership of the Storage Foundation High Availability.
# cpsadm -s cp_server -a list_membership -c cluster_name
Where cp_server is the virtual IP address or virtual hostname on which CP server is configured, and cluster_name is the VCS name for the Storage Foundation High Availability.
