Configuring Shared Storage for the Database Using ASM
To configure your cluster using ASM, perform the following steps on all nodes :
1 Log in as root .
2 On all the nodes, create one partition on each of the other two external storage
devices with the
fdisk utility:
a Create a primary partition for the entire device by typing:
fdisk /dev/emcpowerX
NOTE: Type h for help within the fdisk utility.
b
Verify that the new partition exists by typing:
cat /proc/partitions
If you do not see the new partition, type:
sfdisk -R /dev/<device name>
3 Ty p e chkconfig networkwait off .
NOTE: Shared storage configuration using ASM can be done either using the
Block Devices or the Oracle ASM library driver.
Configuring Shared Storage Using Block Devices
1 Add the disk group names for asm1 and asm2 to the permissions.ini
file. This file is located in the following directory:
/dell-oracle-deployment/scripts/
[asm]
asm1=
asm2=
For example, if your ASM1 and ASM2 disk groups are /dev/emcpowerc1 and
/dev/emcpowerd1 , then the permissions.ini would be modified as
follows:
[asm]
asm1=/dev/emcpowerc1
asm2=/dev/emcpowerd1
To add an additional ASM disk group, ASM3 using /dev/emcpowere1 ,
add another entry to the session:
asm3=/dev/emcpowere1
