6 Verify that the ASM disks are created and marked for ASM usage.
In the terminal window, type the following and press <Enter>:
service oracleasm listdisks
The disks that you created in step 5 are displayed. For example:
ASM1
ASM2
7 Ensure that the remaining nodes are able to access the ASM disks that
you created in step 5. On each remaining node, open a terminal window,
type the following, and press <Enter>:
service oracleasm scandisks

1 Log in as root .
2 Open a terminal window and log in as root .
3 For Enterprise Linux 4:
Copy the /etc/sysconfig/rawdevices file from one of the existing nodes to
the same location on the new node.

4 Open a terminal window and perform the following steps on the new node:
a Ty p e : service oracleasm configure
b Enter the following inputs for all the nodes:
Default user to own the driver interface [ ] : oracle
Default group to own the driver interface [ ] : dba
Start Oracle ASM library driver on boot (y/n) [n] : y
Fix permissions of Oracle ASM disks on boot (y/n) [y] : y

Perform step 5 only if the RAC configuration uses an EqualLogic iSCSI
storage and a Linux Device Mapper Multipath driver. Set the
ORACLEASM_SCANORDER parameter in
/etc/sysconfig/oracleasm
as follows:
ORACLEASM_SCANORDER="dm"
Reboot the system for the change to take effect.
