Adding a Mirror location for the OCR and Voting disk

With 11g R1, you can add the redundant copies of OCR and the Voting disk
while the Clusterware is running across the nodes.
First, You need to log in as root to run the commands.

To add a redundant copy for OCR on a shared storage location :
run the following command:
./$ORA_GRID_HOME/bin/ocrconfig –add /dev/sdf1 --new_location_path

To place the redundant copy in ASM disk group.use the following
command. Ensure the diskgroup is created with the COMPATIBLE.ASM attribute and
that the value is set to 11.2 and mounted on all ASM instances of the cluster.
./ocrconfig –add +OCRVOTE

To add a redundant copy of a Voting disk file on a shared storage location:
use the following command as root user. However, you cannot add a redundant copy of a
Voting disk when it is placed on the ASM storage.
./$ORA_GRID_HOME/bin/crsctl add css votedisk /dev/sdg1 --new_location_path
