Power Off Sequence for Exadata Stack


Poweroff Database Servers

For single server power off /Restart

1. First stop the oracle cluster with below command

#$GRID_HOME/grid/bin/crsctl stop cluster

2. If it fails to stop the cluster then use -f option to stop it forcefully.
Shutdown the server with below command

#shutdown -h -y now

To restart the server execute below command

#shutdown -r -y now      or      #reboot

3. Remove power cable from the server

For multiple servers poweroff/restart with dcli utility

1. First stop the oracle cluster with below command

#$GRID_HOME/grid/bin/crsctl stop cluster -all

2. Shutdown all the servers with dcli utility

#dcli -g dbs_group -l root shutdown -h -y now

---dbs_group is the file which contains the list of all the exadata servers.

To restart the server execute below command

#dcli -g dbs_group -l root shutdown -r -y now    or  #dcli -g dbs_group -l root reboot

----dbs_group is the file which contains the list of all the exadata servers.

3. Remove power cables from the servers

Poweroff Storage Servers

Reat the same procedure of server to power off the exadata storage servers except to stopping the crsctl.

Note: We have to use cell_group file instead of dbs_group file to shutdown the storage servers.

Poweroff Network Equipments

We can directly remove power cables from the network switches as network equipments don't have power switches.
