Adding new OCFS disk to Oracle cluster on Windows

ASulthan Oct 17, 2013 3:11 AM

We have 2 servers running Oracle 11gR2 Window server 2008 64 bit RAC. Today I add new shared disk visible from both servers. All our data placed on ASM partitions, but we need Windows volume for exchanging some data between servers & users;

Actions:

then i have prepare disk on shared storage
from 1st node, run diskmfmt.msc & rescan disks when windows recognizes new hdd, initialize it.
create an Extended partition & Logical drive & Assign drive letter. from another nodes, make sure no drive letter is assigned. Sometimes Windows automatically assign drive letter. If drive letter is assigned, right click & Change drive letter & Remove. from 1st node, format this logical drive using ocfsFormat.exe
after execute below scripts i have face some issues

E:\app\11.2.0\grid\cfs>ocfsformat /m P: /c 1024 /v DATA /f /d /a

RegGetClusterName(): RegQueryValueEx for CFS_CLUSTER_NAME failed with error 203

This indicates that the Cluster Name has not been configured on this node for OCFS

The volume formatted in this condition will be seen by all nodes running OCFS.

how to resolve this steps

Thanks

Hi,

If you are using Oracle version 11.2.0.2 or newer you might want to use Oracle ACFS instead of ocfs.
This is because ACFS comes with ASM and you can use it via asmca or via command line.
So you do not need ocfs in same nodes that already have ASM. And ACFS also support RMAN backups.

More info in MOS (My Oracle Support) document:
ACFS Technical Overview and Deployment Guide [ID 948187.1]
and
Oracle ACFS Command-line Tools for Windows Environments

Hi

we need configure sepreate FRA location on Windows users want exchange so data client and servers ACFS is not supported for FRA location,
More info in MOS Are ACFS or DBFS Supported Locations for FAST_RECOVERY_AREA? (Doc ID 1521643.1)

I'm not sure that I understand your need here? If you want that Windows Operating System users can share data between client/server then you should use only shared disk (for example ACFS, OCFS or windows own share mechanics.) without database. So why to use FAST_RECOVERY_AREA for that at all?
