If you are using ASM, ensure that the new nodes can access the ASM disks with the same permissions
as the existing nodes.
To configure the ASM disks:
1
Log in as root .
2 If your existing nodes were not configured using raw devices, go to step 3.
If your existing nodes were configured using raw devices for CRS:
a Type the following commands to change the names of the raw character devices to make them
identifiable:
mv /dev/raw/raw1 /dev/raw/votingdisk
mv /dev/raw/raw2 /dev/raw/ocr.dbf
mv /dev/raw/raw3 /dev/raw/spfile+ASM.ora
b Type the following commands to set user oracle ownership of the Cluster Repository
and voting disk:
chown oracle.dba /dev/raw/votingdisk
chown oracle.dba /dev/raw/ocr.dbf
chown oracle.dba /dev/raw/spfile+ASM.ora
3
Type the following commands to change the names of the raw character devices and make them
identifiable as configured on the existing nodes:
mv /dev/raw/raw4 /dev/raw/ASM1
mv /dev/raw/raw5 /dev/raw/ASM2
4
Type the following commands to set user oracle ownership of the Datafile disk and Flashback
Recovery disk:
chown oracle.dba /dev/raw/ASM1
chown oracle.dba /dev/raw/ASM2
5
Copy the /etc/sysconfig/rawdevices file from one of the existing nodes to the same location
on the new node.
