请教高手集群配置问题！

硬件环境 ：四路 intel双核CPU 3.6G/4G内存/2*73G sas硬盘
操作系统 ：RedHat AS 4 update 2 64位
内核版本 ：2.6.9-22.ELsmp
安装了RedHat十一张盘中自带的Red Hat Cluster Suite，按照rh-cs-en-4.pdf手册进行了双节点集群的配置，但是按照手册上所说的
“5. Stop the cluster software on the two running nodes by running the following commands
at each node in this order:
a. service rgmanager stop
b. service gfs stop, if you are using Red Hat GFS
c. service clvmd stop
d. service fenced stop
e. service cman stop
f. service ccsd stop”
和
“6. Start cluster software on all cluster nodes (including the added one) by running the
following commands in this order:
a. service ccsd start
b. service cman start
c. service fenced start
d. service clvmd start
e. service gfs start, if you are using Red Hat GFS
f. service rgmanager start”
其中的clvmd进程，系统中提示不存在，而且fenced、cman、ccsd服务停掉就无法再启动，打开system-config-cluster,系统提示(because this node is not currently part of a cluster,the management tab for this application is not available!)
请高手指点是怎么回事，谢谢！！
