这篇文章[239998.1]可以帮助DBA分析和理解如何将安装失败的10g和11.1版本的CRS成功卸载，该篇文章适用于清除安装失败的10.1.0.2 to 11.1.0.7版本的CRS，对于清除安装失败11.2版本的CRS请参考文档[942166.1 How to Proceed from Failed 11gR2 Grid Infrastructure (CRS) Installation]
Not cleaning up a failed CRS install can cause problems like node reboots. Follow these steps to clean up a failed CRS install:
1. Run the rootdelete.sh script then the rootdeinstall.sh script from the $ORA_CRS_HOME/install directory on any nodes you are removing CRS from. Running these scripts should be sufficent to clean up your CRS install. Rootdelete.sh accepts options like nosharedvar/sharedvar, and nosharedhome/sharedhome. Make yourself familiar with these options by reading the Oracle Clusterware and Oracle Real Application Clusters Administration and Deployment Guide. If you have any problems with these scripts please open a service request.
If for some reason you have to manually remove the install due to problems with the scripts, continue to step 2:
2. Stop the Nodeapps on all nodes:
srvctl stop nodeapps -n
3. Prevent CRS from starting when the node boots. To do this issue the following as root:
Sun:
rm /etc/init.d/init.cssd
rm /etc/init.d/init.crs
rm /etc/init.d/init.crsd
rm /etc/init.d/init.evmd
rm /etc/rc3.d/K96init.crs
rm /etc/rc3.d/S96init.crs
rm -Rf /var/opt/oracle/scls_scr
rm -Rf /var/opt/oracle/oprocd
rm /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab
Linux:
rm /etc/oracle/*
rm -f /etc/init.d/init.cssd
rm -f /etc/init.d/init.crs
rm -f /etc/init.d/init.crsd
rm -f /etc/init.d/init.evmd
rm -f /etc/rc2.d/K96init.crs
rm -f /etc/rc2.d/S96init.crs
rm -f /etc/rc3.d/K96init.crs
rm -f /etc/rc3.d/S96init.crs
rm -f /etc/rc5.d/K96init.crs
rm -f /etc/rc5.d/S96init.crs
rm -Rf /etc/oracle/scls_scr
rm -f /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab
HP-UX:
rm /sbin/init.d/init.cssd
rm /sbin/init.d/init.crs
rm /sbin/init.d/init.crsd
rm /sbin/init.d/init.evmd
rm /sbin/rc2.d/K960init.crs
rm /sbin/rc2.d/K001init.crs
rm /sbin/rc3.d/K960init.crs
rm /sbin/rc3.d/S960init.crs
rm -Rf /var/opt/oracle/scls_scr
rm -Rf /var/opt/oracle/oprocd
rm /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab
HP Tru64:
rm /sbin/init.d/init.cssd
rm /sbin/init.d/init.crs
rm /sbin/init.d/init.crsd
rm /sbin/init.d/init.evmd
rm /sbin/rc3.d/K96init.crs
rm /sbin/rc3.d/S96init.crs
rm -Rf /var/opt/oracle/scls_scr
rm -Rf /var/opt/oracle/oprocd
rm /etc/inittab.crs

IBM AIX:
rm /etc/init.crs
rm /etc/init.crsd
rm /etc/init.evmd
rm /etc/rc.d/rc2.d/K96init.crs
rm /etc/rc.d/rc2.d/S96init.crs
rm -Rf /etc/oracle/scls_scr
rm -Rf /etc/oracle/oprocd
rm /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab
4. If they are not already down, kill off EVM, CRS, and CSS processes or reboot the node:
ps -ef | grep crs
kill -9 procid
ps -ef | grep evm
kill -9 procid
ps -ef | grep css
kill -9 procid
Do not kill any OS processes, for example icssvr_daemon process !
5. If there is no other Oracle software running (like listeners, DB’s, etc…), you can remove the files in /var/tmp/.oracle or /tmp/.oracle. Example:
rm -f /var/tmp/.oracle/* 或者 rm -f /tmp/.oracle/*
6. Remove the ocr.loc, usually the ocr.loc can be found at /etc/oracle
7. De-install the CRS home in the Oracle Universal Installer
8. Remove the CRS install location.
9. Clean out the OCR and Voting Files with dd commands. Example:
dd if=/dev/zero of=/dev/rdsk/V1064_vote_01_20m.dbf bs=1M count=256
dd if=/dev/zero of=/dev/rdsk/ocrV1064_100m.ora bs=1M count=256
See the Clusterware Installation Guide for sizing requirements…
If you placed the OCR and voting disk on a shared filesystem, remove them.
If you are removing the RDBMS installation, also clean out any ASM disks if they have already been used.
10. The /tmp/CVU* dir should be cleaned also to avoid the cluvfy misreporting.
11. It is good practice to reboot the node before starting the next install.
12. If you would like to re-install CRS, follow the steps in the Oracle Clusterware Installation manual.
