Oracle升级回退：10.2.0.4 crs升级到11.2.0.4 回退方案
1，停数据库
$ srvctl stop instance -d sol -i sol1 -o abort
$ srvctl stop instance -d sol -i sol2 -o abort
2，deconfig gi的信息
两个节点同时执行这个操作
# .//crs/install/rootcrs.pl -verbose -deconfig -force
Using configuration parameter file: crs/install/crsconfig_params
Network exists: 1/192.168.111.0/255.255.255.0/e1000g0, type static

3，还原文件
两个节点都要执行

4，还原ocr/vote
# su - oracle
Oracle Corporation SunOS 5.10 Generic Patch January 2005
$ dd if=/soft/votevol of=/dev/vx/rdsk/ocrvotedg/votevol
dd: /dev/vx/rdsk/ocrvotedg/votevol: open: No such file or directory
dd if=/soft/votevol of=/dev/vx/rdsk/ocrvotedg/votevoldd if=/soft/ocrvol of=/dev/vx/rdsk/ocrvotedg/ocrvol
5，启动crs
两边同时启动crs
/etc/init.d/init.crs start
# hostname
sol1
# crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy# crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
6，查看资源
# crs_stat -t
Name Type Target State Host

资源全部正常，回退相当的方便。
