NOTE: Shared storage configuration using ASM can be done either using the RAW device interface or the Oracle
ASM library driver.
Configuring Shared Storage Using the RAW Device Interface
1 Edit the /etc/sysconfig/rawdevices file and add the following lines for a Fibre Channel cluster:
/dev/raw/ASM1 /dev/emcpowerb1
/dev/raw/ASM2 /dev/emcpowerc1
2
Create the RAW devices by typing:
udevstart
3 Restart the RAW Devices Service by typing:
service rawdevices restart
4 To add an additional ASM disk (for example, ASM3 ), edit the /etc/udev/scripts/raw-dev.sh file on all
the nodes and add the appropriate bold entries as shown below:
MAKEDEV raw
mv /dev/raw/raw1 /dev/raw/votingdisk
mv /dev/raw/raw2 /dev/raw/ocr.dbf
mv /dev/raw/raw3 /dev/raw/spfile+ASM.ora
mv /dev/raw/raw4 /dev/raw/ASM1
mv /dev/raw/raw5 /dev/raw/ASM2
mv /dev/raw/raw6 /dev/raw/ASM3
chmod 660
/dev/raw/{votingdisk,ocr.dbf,spfile+ASM.ora,ASM1,ASM2,ASM3}
chown oracle.dba
/dev/raw/{votingdisk,ocr.dbf,spfile+ASM.ora,ASM1,ASM2,ASM3}
To add additional ASM disks type udevstart on all the nodes and repeat step 4.
Configuring Shared Storage Using the ASM Library Driver
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
