70 Configuring Database Storage on the Host
Configuring Disks for ASM Using the ORACLEASM Library Driver
Perform the following steps 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 Type 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
3 Perform this step only if the RAC configuration uses a shared storage and a
Linux Device Mapper Multipath driver.
a Set the ORACLEASM_SCANORDER parameter in
/etc/sysconfig/oracleasm as follows: ORACLEASM_SCANORDER=
"dm"
NOTE: If you use EMC storage for RAC configuration, set the
ORACLEASM_SCANORDER parameter in /etc/sysconfig/oracleasm to
"emcpower".
b Reboot the system for the change to take effect.
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
5 Repeat step 4 for any additional ASM disks that need to be created.
