Configuring Shared Storage With ASM
Configuring Shared Storage for Cluster Ready Service (CRS)
To configure shared storage with ASM, perform the following steps:
1
On the first node , create three partitions on an external storage device with fdisk .
Create three partitions of 150 MB each for the cluster repository, Voting Disk, and the Oracle system
parameter file by typing:
fdisk /dev/emcpowerx
2
On each node , verify the new partitions by typing:
more /proc/partitions
If the new partitions do not appear in the /proc/partitions file, type:
sfdisk -R /dev/<device name>
a Start the raw devices by typing:
udevstart
b Edit the /etc/sysconfig/rawdevices file and add the following lines for a Fibre Channel cluster:
/dev/raw/votingdisk /dev/emcpowera1
/dev/raw/ocr.dbf /dev/emcpowera2
/dev/raw/spfile+ASM.ora /dev/emcpowera3
c Restart the Raw Devices Service by typing:
service rawdevices restart
Configuring Shared Storage for Database

the ASMLib software.
