三、停止ntp服务，11gR2新增的检查项，配置集群时间同步服务
[[email?protected] ~]# service ntpd status
[[email?protected] ~] #service ntpd stop
[[email?protected] ~] #chkconfig –level 2345 ntpd off
[[email?protected] ~] #rm –rf /etc/ntp.conf
节点二和节点三上执行相同的命令，卸载NTP
在集群安装完后，要确认ctssd是否处于活动状态
[[email?protected] ~] #crsctl check ctss
问题1：
[[email?protected] ~]# iscsiadm -m discovery -t st -p 192.168.0.10 ##用iscsiadm探测openfiler新添加的iscsi共享卷
-bash: iscsiadm: command not found
[[email?protected] ~]# mount /dev/cdrom /media --加载光盘，安装iscsi-initiator rpm包
解决：
[[email?protected] Packages]# pwd
/mnt/cdrom/Packages
[[email?protected] Packages]# yum install iscsi* #iscsi-initiator-utils-6.2.0.868-0.18.el5.i386.rpm
[[email?protected]~] # rpm –ivh scsi-target-utils*.rpm
// RedHat 6在光盘Packages目录下
// RedHat 5在光盘ClusterStorage目录下 （编辑：PHP编程网 - 湛江站长网）
