68 Configuring Database Storage on the Host
Configuring Shared Storage for Clusterware,
Database and Recovery Files in a RAC
Environment
Use the ORACLEASM library driver to configure disks for Automatic Storage
Management (ASM). To configure the ASM disks:
1
Log in as root .
2 Open a terminal window and perform the following steps on all nodes:
a Ty p e service oracleasm configure
b Enter the following inputs for all the nodes:
Default user to own the driver interface [ ]: grid
Default group to own the driver interface [ ]: asmadmin
Start Oracle ASM library driver on boot (y/n) [n]: y
Fix permissions of Oracle ASM disks on boot (y/n) [y]: y
3
Perform this step only if the RAC configuration uses an EqualLogic iSCSI
storage and a Linux Device Mapper Multipath driver.
a Set the ORACLEASM_SCANORDER parameter in
/etc/sysconfig/oracleasm to dm .
b Reboot the system to apply the changes.
4 On the first node in the terminal window, type the following and press
<Enter>:
service oracleasm createdisk ASM1 /dev/emcpowerb1
service oracleasm createdisk ASM2 /dev/emcpowerc1

Repeat step 4 for any additional ASM disks that need to be created.
