Oracle Grid Standalone update 11.2.0.3 to 11.2.0.4

Backup ASM spfile
$srvctl config asm
ASM home: /u01/app/oracle/product/11.2.0/grid
ASM listener: LISTENER
Spfile: +DATA/asm/asmparameterfile/registry.253.811613369
ASM diskgroup discovery string: /dev/oracleasm/disks/*

$asmcmd

spbackup +DATA/ASM/ASMPARAMETERFILE/REGISTRY.253.811613369 /home/oracle/init+ASM.ora.backup

Backup OLR:
The default backup location for the OLR is in the path Grid_home/cdata/host_name

#ocrconfig –local –manualbackup

To restore OLR:
# crsctl stop crs
# ocrconfig -local -restore file_name
# ocrcheck -local
# crsctl start crs
$ cluvfy comp olr

Begin update
Shutdown the database, oem.
. oraenv prompt dbsid
$emctl stop dbconsole
$srvctl stop database -d dbsid

$unset ORA_CRS_HOME
$unset ORACLE_BASE
$unset ORACLE_HOME
$unset ORACLE_SID
Recommended practice is to upgrade an Oracle ASM instance with Oracle Universal Installer or asmca (after install new GI home) ./runInstaller

Confirm that asm, listener, database, oem are running.
. oraenv
+ASM
$crsctl stat res -t

. oraenv
dbsid
$srvctl start database -d dbsid
$emctl start dbconsole
