Adding ocrmirror and voting disk on another diskgroup 11gr2 RAC

Hi Gurus,
Can i add ocrmirror on another diskgroup(external redundancy) and voting disk(normal) on anotherdiskgroup (replace) in 11gr2 RAC while databases are up and running?

Hi
in Oracle 11gr2 voting disk are backed up automatically in the ocr part of any configuration change
Voting disk is automatically restored to any added voting disk
You can migrate voting fıska from non asm to asm without
Taking download cluster
To add a voting disk to asm
Crsctl replace votedisk +diskgroup
Ocrconfig -add +datagroup2
Oracle manage up to five redundant ocr locations
Hope this helps

OCR and voting disks on ASM, problems in case of fail-over instances

Hi everybody
in case at your site you :
- have an 11.2 fail-over cluster using Grid Infrastructure (CRS, OCR, voting disks),
where you have yourself created additional CRS resources to handle single-node db instances,
their listener, their disks and so on (which are started only on one node at a time,
can fail from that node and restart to another);
- have put OCR and voting disks into an ASM diskgroup (as strongly suggested by Oracle);
then you might have problems (as we had) because you might:
- reach max number of diskgroups handled by an ASM instance (63 only, above which you get ORA-15068);
- experiment delays (especially in case of multipath), find fake CRS resources, etc.
whenever you dismount disks from one node and mount to another;
So (if both conditions are true) you might be interested in this story,
then please keep reading on for the boring details.
One step backward (I'll try to keep it simple).
Oracle Grid Infrastructure is mainly used by RAC db instances,
which means that any db you create usually has one instance started on each node,
and all instances access read / write the same disks from each node.
So, ASM instance on each node will mount diskgroups in Shared Mode,
because the same diskgroups are mounted also by other ASM instances on the other nodes.
ASM instances have a spfile parameter CLUSTER_DATABASE=true (and this parameter implies
that every diskgroup is mounted in Shared Mode, among other things).
In this context, it is quite obvious that Oracle strongly recommends to put OCR and voting disks
inside ASM: this (usually called CRS_DATA) will become diskgroup number 1
and ASM instances will mount it before CRS starts.
Then, additional diskgroup will be added by users, for DATA, REDO, FRA etc of each RAC db,
and will be mounted later when a RAC db instance starts on the specific node.
In case of fail-over cluster, where instances are not RAC type and there is
only one instance running (on one of the nodes) at any time for each db, it is different.
All diskgroups of db instances don't need to be mounted in Shared Mode,
because they are used by one instance only at a time
(on the contrary, they should be mounted in Exclusive Mode).
Yet, if you follow Oracle advice and put OCR and voting inside ASM, then:
- at installation OUI will start ASM instance on each node with CLUSTER_DATABASE=true;
- the first diskgroup, which contains OCR and votings, will be mounted Shared Mode;
- all other diskgroups, used by each db instance, will be mounted Shared Mode, too,
even if you'll take care that they'll be mounted by one ASM instance at a time.
At our site, for our three-nodes cluster, this fact has two consequences.
One conseguence is that we hit ORA-15068 limit (max 63 diskgroups) earlier than expected:
- none ot the instances on this cluster are Production (only Test, Dev, etc);
- we planned to have usually 10 instances on each node, each of them with 3 diskgroups (DATA, REDO, FRA),
so 30 diskgroups each node, for a total of 90 diskgroups (30 instances) on the cluster;
- in case one node failed, surviving two should get resources of the failing node,
in the worst case: one node with 60 diskgroups (20 instances), the other one with 30 diskgroups (10 instances)
- in case two nodes failed, the only node survived should not be able to mount additional diskgroups
(because of limit of max 63 diskgroup mounted by an ASM instance), so all other would remain unmounted
and their db instances stopped (they are not Production instances);
But it didn't worked, since ASM has parameter CLUSTER_DATABASE=true, so you cannot mount 90 diskgroups,
you can mount 62 globally (once a diskgroup is mounted on one node, it is given a number between 2 and 63,
and other diskgroups mounted on other nodes cannot reuse that number).
So as a matter of fact we can mount only 21 diskgroups (about 7 instances) on each node.
The second conseguence is that, every time our CRS handmade scripts dismount diskgroups
from one node and mount it to another, there are delays in the range of seconds (especially with multipath).
Also we found inside CRS log that, whenever we mounted diskgroups (on one node only), then
behind the scenes were created on the fly additional fake resources
of type ora*.dg, maybe to accomodate the fact that on other nodes those diskgroups were left unmounted
(once again, instances are single-node here, and not RAC type).
That's all.
Did anyone go into similar problems?
We opened a SR to Oracle asking about what options do we have here, and we are disappointed by their answer.
Regards
Oscar

Hi Klaas-Jan
- best practises require that also online redolog files are in a separate diskgroup, in case of ASM logical corruption (we are a little bit paranoid): in case DATA dg gets corrupted, you can restore Full backup plus Archived RedoLog plus Online Redolog (otherwise you will stop at the latest Archived).
So we have 3 diskgroups for each db instance: DATA, REDO, FRA.
- in case of fail-over cluster (active-passive), Oracle provide some templates of CRS scripts (in $CRS_HOME/crs/crs/public) that you edit and change at your will, also you might create additionale scripts in case of additional resources you might need (Oracle Agents, backups agent, file systems, monitoring tools, etc)
About our problem, the only solution is to move OCR and voting disks from ASM and change pfile af all ASM instance (parameter CLUSTER_DATABASE from true to false ).
Oracle aswers were a litlle bit odd:
- first they told us to use Grid Standalone (without CRS, OCR, voting at all), but we told them that we needed a Fail-over solution
- then they told us to use RAC Single Node, which actually has some better features, in csae of planned fail-over it might be able to migreate
client sessions without causing a reconnect (for SELECTs only, not in case of a running transaction), but we already have a few fail-over cluster, we cannot change them all
So we plan to move OCR and voting disks into block devices (we think that the other solution, which needs a Shared File System, will take longer).
Thanks Marko for pointing us to OCFS2 pros / cons.
We asked Oracle a confirmation that it supported, they said yes but it is discouraged (and also, doesn't work with OUI nor ASMCA).
Anyway that's the simplest approach, this is a non-Prod cluster, we'll start here and if everthing is fine, after a while we'll do it also on Prod ones.

How do I define 2 disk groups for ocr and voting disks at the oracle grid infrastructure installation window

Hello,
It may sound too easy to someone but I need to ask it anyway.
I am in the middle of building Oracle RAC 11.2.0.3 on Linux. I have 2 storage and I created three LUNs in each of storage so 6 LUNs in total look in both of servers. If I choose NORMAL as a redundancy level, is it right to choose my 6 disks those are created for OCR_VOTE at the grid installation? Or should I choose only 3 of them and configure mirroring at latter stage?
The reason why I am asking this is that I didn't find any place to create asm disk group for ocr and voting disks at the oracle grid infrastructure installation window. In fact, I would to like to create two disk groups in which one of groups contains three disks those were brought from storage 1 and the second one contains rest three 3 disk that come from the last storage.
I believe that you will understand the manner and help me on choosing proper way.
Thank you.

Hi,
You have 2 Storage H/W.
You will need to configure a Quorum ASMDisk to store a Voting Disk.
Because if you lose 1/2 or more of all of your voting disks, then nodes get evicted from the cluster, or nodes kick themselves out of the cluster.
You must have the odd number of voting disk (i.e 1,3 or 5) one voting disk per ASM DISK, So 1 Storage will hold more voting disk than another storage.
(e.g 3 Voting Disk - 2 voting stored in stg-A and 1 voting disk store in stg-B)
If fail the storage that hold the major number of Voting disk the whole cluster (all nodes) goes down. Does not matter if you have a other storage online.
It will happen:

OCR and Voting Disk Migration to new media

Hello,
We need to move OCR,voting disk and ASM from one storage media to another .I think ASM related files are very easy to move/re map but how OCR and Voting Disk files will be migrated to the new storage media?
Thanks,
S.Mann

Hi,
when you said:
"Move Voting Disk : run as root.
crsctl query css votedisk
crsctl add css votedisk new_backup_san_device
crsctl query css votedisk - Make sure the new device is added
crsctl delete css votedisk current_san_device_to_be_encrypted
crsctl query css votedisk - Make sure that the old one is removed "
I supose the new_backup_san_device could be a raw device??
In my system I have a 2 nodes cluster, oracle 10gR2, RAC and ASM
the ocr and voting disk are stored in /dev/raw/raw1 and /dev/raw/raw2
thoses 2 raw devices are mapped with LUNS in the first storade media.
We are about to change it..
So what must I do at this step? What are the logical steps I must done?
add the new LUNS in the nodes and map it as raw devices?
I have this at the moment:
crw-r----- 1 root oinstall 162, 1 Feb 8 17:33 /dev/raw/raw1
crw-r----- 1 root oinstall 162, 2 Feb 8 17:33 /dev/raw/raw2
crw-r----- 1 oracle oinstall 162, 3 Feb 8 17:33 /dev/raw/raw3
in the case of migration, I must add 3 new row devices?
as this?
crw-r----- 1 root oinstall 162, 1 Feb 8 17:33 /dev/raw/raw1
crw-r----- 1 root oinstall 162, 2 Feb 8 17:33 /dev/raw/raw2
crw-r----- 1 oracle oinstall 162, 3 Feb 8 17:33 /dev/raw/raw3

crw-r----- 1 root oinstall 162, 2 Feb 8 17:33 /dev/raw/raw5
crw-r----- 1 oracle oinstall 162, 3 Feb 8 17:33 /dev/raw/raw6
That's it?

Help needed : How to move OCR and Voting Disk

Hi all experts...
I am Mahesh. Working in DXB as DBA. We have serveral RAC installed clients. Among those one major client wants their OCR and Voting Disk to be moved from existing SAN to a new SAN which will be configured. Only OCR and Voting Disks needs to be moved.
Details:
=====
Oracle Clusterware,ASM and DB version 10.2.0.3.0
Windows 2003 Server Enterprise Edition
2-Node RAC
OCR and Voting disks are on RAW devices (not on CFS or NFS)
I have read the clusterware administration document and also Metalink Note 428681.1 for the same.
But it does not contain information how to move it to another new RAW in a new SAN device. (we need to keep it in raw device itself)
How to identify the new disk path from windows operating system ? Then only we can move the OCR and VD right ???
Help me for the same please...
Thanks & regards,
Mahesh.

Hi Mashes,
Could you list out the steps you did after you create the link on the new SAN using GUIObjectManager.exe?
I tried on my VM and also in customer's test environment but I only successful using the following steps
1. shutdown asm service, database service, listener service, CRS, EVM and CSS
2. Object Manager Service is kept running
3. from both nodes I issued the following command
ocrconfig -repair \\.\OCRPRIMARY
ocrconfig -repair \\.\OCRMIRROR
4. according to metalink id 428681.1, I should do the following
ocrconfig -overwrite
However I was not successful because that command returns an error message (PROT-1: Failed to initialize ocr config).
Therefore, I ran the following command
ocrconfig -restore D:\oracle\1020\CRS\cdata\crs\backup00.ocr
5. after that command, ocrcheck giving me the result and the ocr primary and mirror have been moved to the new partition.
6. start the whole services starting from CSS, EVM, CRS, ASM, Listerner and Database service.
Although what I experienced seems a bit weird and not the same as what was written in metalink, the RAC is running fine until now.
What I would like to know is your experience on this. May be you can share it here.
Thank you,
Adhika

OCR and VOTING DISK for RAC Database on ASMLib env

Where to put OCR and Voting disks?

Hi,
I will be installing Clusterware 11.2.0.2 on a 2 node cluster. I have read several whitepapers where a third asm disk group DATA, FRA, and CRS was created to hold the OCR and Voting disks. In the interest of keeping things simple can I just put the OCR and Voting disks in the DATA DG? I am using external SAN storage.
Thanks
Tom Cullen

Hi,
yes that is absolutely possible.
There are several best practices. Some recommend a separate diskgroup, some recommend to put OCR and Voting in the same diskgroup like your data.
So if there is no special use case it is absolutely valid to only use 2 diskgroups. 1 DATA (including OCR and Vote) and 1 FRA (Fast Recovery Area for Database Backups/Archivelogs/1 Controlfile/1 RedologMember and a second copy of OCR).

Confusion with OCFS2 File system for OCR and Voting disk RHEL 5, Oracle11g,

Dear all,
I am in the process of installing Oracle 11g 3 Node RAC database
The environment on which i have to do this implementation is as follows:
Oracle 11g.
Red Hat Linux 5 x86
Oracle Clusterware
ASM
EMC Storage
250 Gb of Storage drive.
SAN
As of now i am in the process of installing Oracle Clusterware on the 3 nodes.
I have performed these tasks for the cluster installs.
1. Configure Kernel Parameters
2. Configure User Limits
3. Modify the /etc/pam.d/login file
4. Configure Operating System Users and Groups for Oracle Clusterware
5. Configure Oracle Clusterware Owner Environment
6. Install CVUQDISK rpm package
7. Configure the Hosts file
8. Verify the Network Setup
9. Configure the SSH on all Cluster Nodes (User Equivalence)
9. Enable the SSH on all Cluster Nodes (User Equivalence)
10. Install Oracle Cluster File System (OCFS2)
11.Verify the Installation of Oracle Cluster File System (OCFS2)
12. Configure the OCFS2 (/etc/ocfs2/cluster.conf)
13. Configure the O2CB Cluster Stack for OCFS2
BUT, here after i am a little bit confused on how to proceed further. The next step is to Format the disk and mount the OCFS2, Create Software Directories... so and so forth.
I asked my system admin to provide me two partitions so that i could format them with OCFS2 file system.
He wrote back to me saying.
*"Is what you want before I do it??*
*/dev/emcpowera1 is 3GB and formatted OCFS2.*
*/dev/emcpowera2 is 3GB and formatted OCFS2.*
*Are those big enough for you? If not, I can re-size and re-format them*
*before I mount them on the servers.*
*the SAN is shared storage. /dev/emcpowera is one of three LUNs on*
*the shared storage, and it's 214GB. Right now there are only two*
*partitions on it- the ones I listed below. I can repartition the LUN any*
*way you want it.*
*Where do you want these mounted at:*
*/dev/emcpowera1*
*/dev/emcpowera2*
*I was thinking if this mounting techique would work like so:*
*emcpowera1: /u01/shared_config/OCR_config*
*emcpowera2: /u01/shared_config/voting_disk*
*Let me know how you'd like them mounted."*
Please recommend me what i should convey to him so that i can ask him to the exact same thing.
My second question is, as we are using ASM, for which i am gonna configure ASM after clusterware installation, should i install Openfiler??
Pls refer the enviroment information i provided above and make recommendations.
As of now i am using Jeffery Hunters guide to install the entire setup. You think the entire install guide goes well with my enviroment??

Thanks for ur reply Mufalani,
You have managed to solve half part of my query. But still i am stuck with what kind of mount point i should ask the system admin to create for OCR and Voting disk. Should i go with the mount point he is mentioning??
Let me put forth few more questions here.
1. Is 280 MB ok for OCR and voting disks respectively??
2. Should i ask the system admin to create 4 voting disk mount points and two for ocr??
3. As mentioned by the system admin.
*/u01/shared_config/OCR_config*
*/u01/shared_config/voting_disk*
Is this ok for creating the ocr and voting disks?
4. Can i use OCFS2 file system for formating the disk instead of using them as RAW device!!?
5. As u mentioned that Openfiler is not needed for Configuring ASM... Could you provide me the links which will guide me to create partition disks, voting disks and ocr disks!! I could not locate them on the doc or else were. I did find a couple of them, but was unable to identify a suitable one for my envoirement.

OCR and Voting Disk partition

Dear all
I uninstall clusterware. And i want to install again that but when i made partition in windows 2003 then CVU fail the stage command.
I did the following things..
1) diskpart --->select Disk 1----> clean -->exit (both the nodes)
2) diskpart -->automount enable--->exit ---> restart (both the nodes)
3) Then i make four partition in one node. And see after restart node 2 have that partition with drive letter. I remove all the drive letter.
But CVU stage command failed. And if i run clusterware then it can get partition which has not previous OCR and voting. I think previous OCR and Voting disk could not clean.
Could u pls tell me how can i get solution.

OCR and Voting Disk Mirror

Hi,
We have oracle 10.2.0.4 RAC database. Now we are planning to mirror the OCR and Voting disk. Currently we are using SAN mirror copy. SAN admin assures that we don't need mirror copy as it is being mirrored at the disk level. Can any one please suggest me if we need any mirror copy of these. If so what advantages I get from the regular SAN copy.

You use SAN or High Availability Storage + RAID. You don't need to mirror OCR/VOTING .
Anyway , If you can do it... Mirror OCR + Multi VOTING... , that's good thing oracle recommend.
By the way, If you can not mirror OCR + multi VOTE on 10g, You should backup VOTE File ("dd" linux command) after setup completed/add node/delete node.

OCR and Voting disk SAN config

Hi,
On our standard SAN configuration I normally use RAID 1 for the OCR and Voting disk raw devices. I'm working with a site that has only RAID 5 for their entire SAN. Will RAID 5 be acceptable for the OCR and Voting disk devices?

Hi,
Yes, you can use it.
It is better to use RAID 1+0, instead of RAID-5.
OCR and voting disks takes very less space, So you can request to change RAID-5 (OCR and voting) disks to RAID 1+0 (OCR and voting) disks.
Changing form RAID-5 to RAID 1+0 may not be require any downtime.
Thanks.

OCR and voting disk locations

How to check the location of the OCR and voting disk?
How to know if they are on OCFS2? On Raw?

The OCRCHECK utility displays the version of the OCR's block format, total space available and used space, OCRID, and the OCR locations that you have configured. OCRCHECK performs a block-by-block checksum operation for all of the blocks in all of the OCRs that you have configured. It also returns an individual status for each file as well as a result for the overall OCR integrity check. The following is a sample of the OCRCHECK output:
Status of Oracle Cluster Registry is as follows :
Version : 2
Total space (kbytes) : 262144
Used space (kbytes) : 16256

AIX 6.1 - Do we need HACMP to store the OCR and Voting Disks on Raw Logical

We are planning to install 11G r1 rac on AIX 6.1. We will use clusterware and ASM. We would like to avoid GPFS and HACMP.
We plan to put the Clusterware OCR and Voting Disks on Raw Logical Volumes.
I do not believe we need HACMP. see the passage below from doc:
Oracle® Clusterware
Installation Guide
11g Release 1 (11.1) for AIX Based Systems
B28258-05
Configuring Raw Disk Devices for Oracle Clusterware Without HACMP or GPFS
If you are installing Oracle RAC on an AIX cluster without HACMP or GPFS, then you
must use shared raw disk devices for the Oracle Clusterware files. You can also use
shared raw disk devices for database file storage. However, Oracle recommends that
you use Automatic Storage Management to store database files in this situation.
This section describes how to configure the shared raw disk devices for Oracle
Clusterware files (Oracle Cluster Registry and Oracle Clusterware voting disk). It also
describes how to configure shared raw devices for Oracle ASM and for Database files,
if you intend to install Oracle Database, and you need to create new disk devices.
Question:
Do we need HACMP to store the OCR and Voting Disks on Raw Logical Volumes? According to the passage above we do not.

You can archive log either in shared location or separate location associated with each instance. Oracle recommends using a shared location for all the instances in a RAC configuration.
