Add New Node to ORACLE RAC

Extend GRID Software
---Step 1:

[root@rac1]$ su - grid
[grid@rac1]$ export GRID_HOME=/u01/app/11.2.0/grid
[grid@rac1]$ $GRID_HOME/bin/cluvfy stage -post hwos -n rac2

----Step 2:
[grid@rac1]$ $GRID_HOME/bin/cluvfy comp peer -refnode rac1 -n rac2 -orainv oinstall -osdba dba -verbose

----Step 3:
Verify New Node (NEW NODE PRE)
$GRID_HOME/bin/cluvfy stage -pre nodeadd -n rac2 -fixup -verbose

----Step 4:

[grid@rac1]$ export IGNORE_PREADDNODE_CHECKS=Y
[grid@rac1]$ $GRID_HOME/oui/bin/addNode.sh -silent "CLUSTER_NEW_NODES={rac2}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={rac2-vip}"

----Step 5:

[root@rac2]$ /u01/app/oraInventory/orainstRoot.sh
[root@rac2]$ /u01/app/11.2.0/grid/root.sh
[grid@rac1]$ $GRID_HOME/bin/cluvfy stage -post nodeadd -n rac2 -verbose

Extend ORACLE DATABASE SOFTWARE

----Step 1:

[oracle@rac1]$ echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0/db_1
[oracle@rac1]$ $ORACLE_HOME/oui/bin/addNode.sh -silent "CLUSTER_NEW_NODES={rac2}"

----Step 2:

[root@rac2]$ /u01/app/oracle/product/11.2.0/db_1/root.sh

[oracle@rac2]$ $ORACLE_HOME/bin/cluvfy comp admprv -o db_config -d $ORACLE_HOME -n rac1,rac2 -verbose

----Step 3:Add Instance to Clustered Database
dbca -> Intance Management -> Add instance
