Oracle 10g RAC Startup/Shutdown services on a single node (for maintenance)

Pre-checks

Oracle Home: 
ORACLE_HOME=/oracle/app/oracle/product/10.2.0/db_1

CRS Home:

Check the status of Cluster services:
 /oracle/crs/oracle/product/10/crs/bin/crs_stat -t

Few commands to check the status of individual cluster services:

For example: 
Server name is cd2-db-svr and cd2-db-svr-bck
Database name is TRAX
Instance name is TRAX01 and TRAX02

cd2-db-svr# srvctl status nodeapps -n cd2-db-svr

VIP is running on node: cd2-db-svr
GSD is running on node: cd2-db-svr
Listener is running on node: cd2-db-svr

ONS daemon is running on node: cd2-db-svr

cd2-db-svr# srvctl status asm -n cd2-db-svr

ASM instance +ASM1 is running on node cd2-db-svr

cd2-db-svr# srvctl status database -d TRAX
Instance TRAX01 is running on node cd2-db-svr

Instance TRAX02 is running on node cd2-db-svr-bck

cd2-db-svr# crsctl check crs

CSS appears healthy
CRS appears healthy

EVM appears healthy

Actual Steps to bring down the services on one node of Oracle 10G RAC cluster

Stop services on  node 1(cd2-db-svr)

1. srvctl stop instance -d TRAX -i TRAX01
2. srvctl stop asm -n cd2-db-svr
3. srvctl stop nodeapps -n cd2-db-svr
4. crsctl stop crs

Start services on node 1(cd2-db-svr)

1. crsctl start crs  (Ideally all services should come up automatically, if not issue the following steps to bring up the services)
2. srvctl start nodeapps -n  cd2-db-svr
3. srvctl start asm -n  cd2-db-svr
4. srvctl start instance -d TRAX -i TRAX01
