RE: Making OCR / VD Visible to BOTH DB Server (SUN) Nodes ... Basic Qs

Folks

How are the Oracle Cluster Registry (OCR) & Voting Disk (VD) device files to be Made Concurrently VISIBLE / Shareable to BOTH Database (Solaris 10) Nodes? Five RAW devices (2 OCR & 3 VD) of 200MB each were created only on the Node 1(Master node).

Aim is to setup a 2 Node ASM RAC.

Qs To make the OCR / VD devices visible to the Other / 2nd Node which of the following 3 Options is applicable:-

1. Solaris/SUN Cluster Setup needed on BOTH Nodes
2. Issue of some Solaris Commands (On HP-UX vgexport, vgimport commands are used to export & import the respective raw devices from the 1st node to the 2nd.)
3. CRS setup automatically make the OCR / VD devices created only on the 1st (Master) Node visible to the 2nd Node without need for any additional O.S. Commands

NOTE - The Storage Box is connected to BOTH the Nodes thru a Switch. NOTE - External Redundancy to be used for ASM DB Setup.

Cheers & Thanks

Vivek

P.S.

Configuration:-
Solaris 10
Oracle 10gR2

Following commands used for creation of OCR / VD device files only on the 1st (master) Node:-

Step 1 - Command for creating the Raw Devices

dd if=/dev/zero of=/asmdata/voting/asm_vote1 bs=1k count=200000 O/P
200000+0 records in
200000+0 records out

Step 2 - Command for creating loop devices so that a character device can be associated with a file

lofiadm -a /asmdata/voting/asm_vote1

O/P: /dev/lofi/1

Step 3 - Command for creating the respective character file to access the file mknod /asmdata/voting/vdiskvote1 c 147 1
