ccs_tool addnode and addfence error invalid option -- \'C\'

ccs_tool addnode and addfence error invalid option -- \'C\' References I\'m installing GFS2 on centos 6 with SAN and fiber channel. I followed this link: http://webcache.googleusercontent.com/search?q=cache:2hpUhuvzlNUJ:linuxdynasty.org/215/howto-setup-gfs2-with-clustering/+&cd=5&hl=en&ct=clnk The first step second step installation completed. But step 3 & 4, I don\'t understand what is gfs1_ipmi or gfs1_vmware... Is this a random name?? And when I run 2 scripts: ccs_tool addfence -C gfs1_ipmi fence_manual ccs_tool addnode -C gfs1 -n 1 -v 1 -f gfs1_vmware Both show error: invalid option -- \'C\'. I search this error but nothing about this. So can you help me resovle these problems and do you have a step by step to install GFS2 on centos 6.4 with SAN and fiber channel? Thanks!
