Failure while formatting raw device for RAC installation

Posted by Kamran Agayev A. on March 17th, 2011

Today, while configuring 2 node RAC on VMware ESX server, I got the following error afer clusterware installation:


Creating OCR keys for user ‘root’, privgrp ‘root’..
Operation successful.
Now formatting voting device: /dev/raw/raw3
Failure writing offset 1766400 in voting device (raw3)
Failed to initialize Oracle Cluster Registry for cluster

After some investigation, we’ve found that the problem is caused by dividing a raw device into two different partitions and the failure occurs after formatting the device. So we deleted those partitions and combined them into one partition and the error fixed.

    i have installed vmware on windows xp.Redhat linux AS4 is installed in vmware.

    uname -i = i386
    uname -r = 2.6.9-5.EL

    I am looking for oracleasm rpm’s related with this Linux OS . Could you please help me identify which rpm’s to download.

    I tried few (http://www.oracle.com/technetwork/server-storage/linux/downloads/rhel4-092650.html), but they are not working except this oracleasm-support-2.1.7-1.el4.i386.rpm

    Please suggest their names and where i can download those rpm’s.

    Best Regards,
