On all the nodes, perform the following steps:
a
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
b
Ty p e
udevstart
to create the RAW devices.
c
Ty p e
service rawdevices restart
to restart the RAW Devices Service.
NOTE: If the three partitions on PowerPath pseudo devices are not consistent across the nodes, modify your
/dev/sysconfig/rawdevices configuration file accordingly.
Configuring Shared Storage for the Database Using ASM
This section provides procedures for configuring the shared storage using ASM.
NOTE: Before you configure the ASM Library Driver, disable SELinux.
To temporarily disable SELinux, perform the following steps:
1
Log in as
root
.
2
At the command prompt, type:
setenforce 0
To permanently disable SELinux, perform the following steps on all the nodes:
1
Open your
grub.conf
file.
2
Locate the kernel command line and append the following option:
selinux=0
For example:
kernel /vmlinuz-2.6.9-34.ELlargesmp ro root=LABEL=/ apic rhgb quiet
selinux=0
3
Reboot your system.
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
Ty p e
fdisk /dev/emcpowerx
and create a primary partition for the entire device.
Ty p e
h
for help within the
fdisk
utility.
b
Ty p e
cat /proc/partitions
to verify that the new partition exists.
If you do not see the new partition, type:
sfdisk -R /dev/<device name>
NOTE: Configure the shared storage using either the RAW device interface or the Oracle ASM library driver.
