Oracle 10g RAC installation: 09 ASM configuration

Tweet

Now we have to create our ASM disks and configure the Oracle Cluster File System where we'll install the Oracle Clusterware.
Start the first node and first of all, simply type as root user

/etc/init.d/oracleasm configure

Type oracle when prompted the default user as owner of the driver interface,
type dba as default group, type y to start the driver on boot and again type y to
fix permissions on boot like in the picture.

Repeat this operation on the second node too.


From only one node (I used rac1 ) type as root user

fdisk -l |grep 261

to see where to create the ASM disks.


We have /dev/sdc1, /dev/sdd1 e /dev/sde1 and so we will create the ASM disks for that devices. The syntax is very easy.

/etc/init.d/oracleasm createdisk ASMD1 /dev/sdc1
/etc/init.d/oracleasm createdisk ASMD2 /dev/sdd1
/etc/init.d/oracleasm createdisk ASMD3 /dev/sde1

Once created, use these commands to scan and list your ASM disks:

/etc/init.d/oracleasm scandisks
/etc/init.d/oracleasm listdisks

Execute the same commands (/etc/init.d/oracleasm scandisks, /etc/init.d/oracleasm listdisks) also from the second node to verify you are able to see the ASM disks.
On the second node you don't have to execute the commands /etc/init.d/oracleasm createdisk
