两个节点分别执行如下操作：

两个节点分别执行如下操作：
crsctl stop crs -f
cd /etc/oracle/
rm -rf scls_scr oprocd lastgasp o* setasmgid
vi  /etc/inittab（去掉ohas那一行[通常是最后一行]）

---检查是否还有d.bin进程，如果kill掉：
ps -ef|grep d.bin
kill -9 pid
---检查ifconfig|grep 169.254如果有类似如下输出，需要重启eth1网卡：
eth1:1    Link encap:Ethernet  HWaddr 08:00:27:89:81:66  
          inet addr:169.254.159.3  Bcast:169.254.255.255  Mask:255.255.0.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1 
ifdown eth1
ifup eth1
ifconfig|grep 169.254
---两节点执行完后可以重新安装
