Cleanup root.sh configuration after a failed CRS 10g, 11.1 installation

Methode 1 : Using rootdelete.sh and rootdeinstall.sh on all rac nodes

# cd /u01/app/oracle/product/crs/install
# ./rootdelete.sh 
# ./rootdeinstall.sh
#   rm -rf /var/tmp/.oracle

Now rerun root.sh 
on ract1
# /u01/app/oracle/product/crs/root.sh
Later run on ract2
# /u01/app/oracle/product/crs/root.sh

Methode 2: Manually deletion

1) Try to stop nodeapps on all cluster nodes
[root@ract1 install]#  srvctl stop nodeapps -n ract1
PRKH-1010 : Unable to communicate with CRS services.
  [OCR Error(Native: prsr_initCLSS:[21])]

[root@ract2 ~]#   srvctl stop nodeapps -n ract2
PRKH-1010 : Unable to communicate with CRS services.
  [OCR Error(Native: prsr_initCLSS:[21])]

2) Cleanup files on all cluster nodes
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

3) Check CRS processes and kill them on all cluster nodes
[root@ract2 rules.d]# ps -ef | egrep  'css|crs|evm'
root      4314     1  0 07:13 ?        00:00:00 /bin/sh /etc/init.d/init.evmd run
root      4315     1  0 07:13 ?        00:00:00 /bin/sh /etc/init.d/init.cssd fatal
root      4316     1  0 07:13 ?        00:00:00 /bin/sh /etc/init.d/init.crsd run
root      4343  4315  0 07:13 ?        00:00:00 /bin/sh /etc/init.d/init.cssd startcheck
root      4365  4314  0 07:13 ?        00:00:00 /bin/sh /etc/init.d/init.cssd startcheck
root      4516  4316  0 07:13 ?        00:00:00 /bin/sh /etc/init.d/init.cssd startcheck
root     16626  9372  0 08:57 pts/1    00:00:00 egrep css|crs|evm
[root@ract2 rules.d]# kill -9 4314 4315 4316 4343 4365 4516
[root@ract2 rules.d]# ps -ef | egrep  'css|crs|evm'
root     18063  9372  0 09:10 pts/1    00:00:00 egrep css|crs|evm

4) Cleanup /var/tmp/.oracle/ and  /tmp/.oracle/ on all cluster nodes
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.
[root@ract2 ~]# rm -f /var/tmp/.oracle/* or rm -f /tmp/.oracle/*

5) Remove the ocr.loc Usually the ocr.loc can be found at /etc/oracle on all cluster nodes
 --> should already clean due to step 1 

6)  Clean out the OCR and Voting Files with dd commands - only on a single node
[root@ract2 ~]# /bin/dd if=/dev/zero skip=25 bs=4k count=2560 of=/dev/raw/raw1
2560+0 records in
2560+0 records out
10485760 bytes (10 MB) copied, 0.248064 seconds, 42.3 MB/s
[root@ract2 ~]#  /bin/dd if=/dev/zero skip=25 bs=4k count=2560 of=/dev/raw/raw2
[root@ract2 ~]#  /bin/dd if=/dev/zero skip=25 bs=4k count=2560 of=/dev/raw/raw3
[root@ract2 ~]#  /bin/dd if=/dev/zero skip=25 bs=4k count=2560 of=/dev/raw/raw4
[root@ract2 ~]#  /bin/dd if=/dev/zero skip=25 bs=4k count=2560 of=/dev/raw/raw5
