60 Configuring Database Storage on the Host
Configuring Shared Storage Disks for Oracle Clusterware Using Raw Devices
1 On the first node, create six partitions on an external storage device with
the
fdisk utility:
Ty p e :
fdisk /dev/emcpowerX ,
and create six partitions of 300 MB each for the Oracle Cluster
Repositories (OCR), Voting Disks, and the Oracle system parameter file.
2 Verify the new partitions by typing: more /proc/partitions
If the new partitions do not appear in the /proc/partitions file, type the
following on all the nodes:
sfdisk -R /dev/<device name>
3
On all the nodes in a Fibre Channel cluster, edit the
/etc/sysconfig/rawdevices file and add the following lines:
/dev/raw/votingdisk1 /dev/emcpowera1
/dev/raw/votingdisk2 /dev/emcpowera2
/dev/raw/votingdisk3 /dev/emcpowera3
/dev/raw/ocr1.dbf /dev/emcpowera4
/dev/raw/ocr2.dbf /dev/emcpowera5
/dev/raw/spfile+ASM.ora /dev/emcpowera6
NOTE: If the three partitions on the PowerPath pseudo devices are not consistent
across the nodes, modify your /dev/sysconfig/rawdevices configuration file
accordingly.
4 Verify that the scripts /etc/udev/scripts/raw-dev.sh and
/etc/udev/rules.d/60-rawdevices.rules exist.
If the scripts exist, continue with the next step in the
Installation Guide . If
the scripts do not exist, follow the
Dell PowerEdge Systems Oracle
Database on Enterprise Linux x86_64 Operating System and Hardware
Installation Guide
to install the Dell|Oracle Deployment Automation
Scripts.
5 Ty p e : chkconfig networkwait off .
6 Create the RAW devices by typing: udevstart
7
Restart the RAW devices service by typing: service rawdevices
restart
