2011-11-23 03:43:24: Failed to write the checkpoint:'' with status:FAIL.Error code is 256
原因：
The problem is caused by clusterware library pointing to non-exist Vendor clusterware library, eg:
$ ls -l /oracle/app/11.2.0.3/grid/lib/libskgxn*
lrwxrwxrwx 1 grid oinstall 33 Nov 23 03:08 /oracle/app/11.2.0.3/grid/lib/libskgxn2.so -> /opt/ORCLcluster/lib/libskgxn2.so
-rwxr-xr-x 1 grid oinstall 159806 Oct 20 23:55 /oracle/app/11.2.0.3/grid/lib/libskgxnr.a
lrwxrwxrwx 1 grid oinstall 33 Nov 23 09:38 /oracle/app/11.2.0.3/grid/lib/libskgxnr.so -> /opt/ORCLcluster/lib/libskgxnr.so

$ ls -l /opt/ORCLcluster
ls: 0653-341 The file /opt/ORCLcluster does not exist.
This is caused by HACMP executable is not removed cleanly when HACMP is deinstalled. When HACMP is installed, it installs the directory /usr/sbin/cluster/utilities along with others. Oracle OUI depends on /usr/sbin/cluster/utilities/cldomain to determine if vendor clusterware exists. If yes, then a symlink of $GRID_HOME/lib/libskgxn2.so will be created pointing to /opt/ORCLcluster/lib/libskgxn2.so (so does libskgxnr.so). /opt/ORCLcluster directory is setup during rootpre.sh if vendor cluster is presented.


In this case, HACMP was first installed, then Veritas software was installed, it caused the /usr/sbin/cluster/utilities/cldomain became a symlink pointing to Veritas clusterware:
$ ls -l /usr/sbin/cluster/utilities/cldomain
lrwxrwxrwx    1 root     system           29 Sep 21 13:54 /usr/sbin/cluster/utilities/cldomain -> /opt/VRTSvcs/rac/bin/cldomain
When HACMP was deinstalled later, it removed all other files but left this symlink cldomain, causing Oracle considered vendor clusterware exists and created the symlink of libskgxn2.so and libskgxnr.so during link libraries phase in OUI installation. Further leads to root.sh failure.
解決方案：
1. When deinstalling vendor clusterware, make sure all associated files are removed. In this case, remove the symlink /usr/sbin/cluster/utilities/cldomain
2. Clean up the failed GI installation via $GRID_HOME/deinstall/deinstall command or clean up manually follow DOCUMENT 1364419.1
3. Reinstall Grid Infrastructure 
注：如果11.2 繼續想使用裸裝置不想解除安裝第三方叢集軟體如HACMP，可以透過如下方式來解決
