Hi all,
target environment:
11.2.0.3 RAC on RHEL 5.7 x86-64
SAN HP 3PAR
I'm reading the following note on MOS: RAC and Oracle Clusterware Best
Practices and Starter Kit (Linux) [ID 811306.1],
in the attached document RACGuides_Rac11gR2OnLinux.pdf is a step by step
description of the GI and RAC installation process.
Does anyone know what's the reason for the requirement for 1 MB offset
for the first sector
and if this requirement is valid on certain types of storage only?
3.1.1. Partition the Shared Disks:
- Once the LUNs have been presented from the SAN to ALL servers in the cluster, partition the LUNs from one node only, run fdisk to create a single whole-disk partition with exactly 1 MB offset on each LUN to be used as ASM Disk.
Thanks
Dimitre
