Your cluster was originally created with nodes RACNODE1 and RACNODE2 three years
ago. Last year, nodes RACNODE3 and RACNODE4 were added. These nodes have faster
processors and more local storage than the original nodes making performance
management and tuning more difficult. Two more nodes with the same processor speed
have been added to the cluster last week as RACNODE5 and RACNODE6 and you must
remove RACNODE1 and RACNODE2 for redeployment. The Oracle Grid Infrastructure is
using GNS and the databases are all 11g Release 2, all running from the same home. The
Grid home is /fs01/home/grid. Which three steps must be performed to remove the nodes
from the cluster?
A.
Run /fs01/home/grid/oui/bin/runInstaller -updateNodeList
ORACLE_HOME=/fs01/home/grid “CLUSTER_NODES= {RACNODE3 , RACNODE4 ,
RACNODE5 , RACNODE6} as the grid software owner on any remaining node.
B.
Run crsctl delete node -n RACNODE1 and crsctl delete node -n RACNODE2 as root
from any node remaining in the cluster.
C.
Run the /fs01/home/grid/crs/install/rootcrs.pl script as root on each node to be deleted.
D.
Run /fs01/home/grid/oui/bin/runInstaller -updateNodeList
ORACLE_HOME=/fs01/home/grid ” CLUSTER_NODES={RACNODE1} as the grid software
owner on RACNODE1 and run /fs01/home/grid/oui/bin/runInstaller – updateNodeList
ORACLE_HOME=/ fs01/home/grid ” CLUSTER_NODES={RACNODE 2} as the grid
software owner on RACNODE2.
E.
Run /fs01/home/grid/oui/bin/runInstaller -detachHome ORACLE_HOME=/fs01/home/grid
as the grid software owner on RACNODE1 and RACNODE2.
