Configuring Storage, Oracle User Equivalence, and Networking for Oracle RAC 59
Configuring Shared Storage Using the Block Devices
NOTE: Before following the steps in this section, follow the procedures listed in the
Configuring the Operating System for Oracle Database Installation section of the
Operating System and Hardware Installation Guide, available from the Dell Support
website at support.dell.com.
1 On the first node , create six partitions on an external storage device with
the
fdisk utility. Type : fdisk /dev/emcpowerX,
and create six partitions of 300 MB each for the OCR, Voting Disks, and the
Oracle system parameter file.
2 Verify the new partitions by typing: more /proc/partitions
On all the nodes, if the new partitions do not appear in the
/proc/partitions file, type: sfdisk -R /dev/<device name>
3 On all the nodes in a Fibre Channel cluster, perform the following steps:
a Add the partition names for the primary and mirror OCR to the
permissions.ini file. This file is located in the
/dell-oracle-deployment/scripts/ directory:
[
ocr]
primary_ocr=
mirror_ocr1=
[vote]
vote1=
vote2=
vote3=
[asm]
asm1=
asm2=
For example, if the OCR and OCR mirror partitions are
/dev/emcpowera1
and /dev/emcpowera2 , then the permissions.ini file
is
modified as follows:
[ocr]
primary_ocr=/dev/emcpowera1
mirror_ocr1=/dev/emcpowera2
