If you encountered a split-brain condition, use the vxfenclearpre utility to remove CP Servers, SCSI-3 registrations, and reservations on the coordinator disks, Coordination Point servers, as well as on the data disks in all shared disk groups.
You can also use this procedure to remove the registration and reservation keys of another node or other nodes on shared disks or CP server.
To clear keys after split-brain
# hastop -all
# gabconfig -a
Port h must not appear in the output.
# /etc/init.d/vxfen.rc stop
# /opt/VRTSvcs/vxfen/bin/vxfenclearpre
Do you still want to continue: [y/n] (default : n) y
