Multiplexing Voting Disk in Oracle 11gR2 ??
Dear all,
I have single voting disk residing in data group VDOCRDG with external redundancy. I would like to add two more voting disks to this group. Could you please let me know a way to add 2 more vd's to this disk group or should i create a new disk group with normal redundancy ???
Appreciate if you could provide your answer with SQL commands.
database: oracle 11g r2 patch-1
os: RHEL 5.5
RAC: two-node RAC
ASM: voting disk and OCR reside in ASM
let me know if you need more information.
thanks

Just out of curiosity:
(Obviously this is a doc question)
is http://tahiti.oracle.com broken for you, so you must ask others to abstract the documentation for free, or don't you understand the line in the Forums ltiEtiquette Post
reading 'Consulting documentation first is highly recommended'?
I'm getting a bit annoyed by people trying to outsource as much of the task they get paid for to a forum of volunteers.

Hello all,
I'm aware of the fact that the voting disks manage current cluster/node membership information and that various nodes constantly check in with voting disk to register their availability. If a node is unable to ping the voting disk the cluster evicts that node to avoid split brain situation. These are some of the points that I don't understand as documentaion is not very clear. Could you explain or post links that have a clear explanation?
1) Why do we have to create odd number of voting disk?
2) Does the cluster actually check for the vote count before node eviction? If yes, could you expain this process briefly?
3) What's the logic behind the documentaion note that says that "each node should be able to see more than half of the voting disks at any time"?
Thanks1) Why do we have to create odd number of voting disk?As far as voting disks are concerned, a node must be able to access strictly more than half of the voting disks at any time. So if you want to be able to tolerate a failure of n voting disks, you must have at least 2n+1 configured. (n=1 means 3 voting disks). You can configure up to 32 voting disks, providing protection against 15 simultaneous disk failures.
Oracle recommends that customers use 3 or more voting disks in Oracle RAC 10g Release 2. Note: For best availability, the 3 voting files should be physically separate disks. It is recommended to use an odd number as 4 disks will not be any more highly available than 3 disks, 1/2 of 3 is 1.5...rounded to 2, 1/2 of 4 is 2, once we lose 2 disks, our cluster will fail with both 4 voting disks or 3 voting disks.
2) Does the cluster actually check for the vote count before node eviction? If yes, could you expain this process briefly?Yes. If you lose half or more of all of your voting disks, then nodes get evicted from the cluster, or nodes kick themselves out of the cluster.
3) What's the logic behind the documentaion note that says that "each node should be able to see more than half of the voting disks at any time"?The answer to first question itself will provide answer to this question too. -
Minimum number of voting disks?
Hi,
Is there is a minimum number of voting disks?
does that depend on the RAC nodes?
If I have 4 nodes what is the optimal voting disks?
Thanksuser9202785 wrote:

ThanksOracle recommends 3 voting disk. but you can install clusterware with one voting disk by selecting external redudancy during clusterware installation.
the number of voting disks is not depend on the number of RAC nodes. you can have upto maximum 32 voting disks for 2nodes to 100 RAC nodes.
The Oracle Clusterware is comprised primarily of two components: the voting disk and the OCR (Oracle Cluster Registry). The voting disk is nothing but a file that contains and manages information of all the node memberships and the OCR is a file that manages the cluster and RAC configuration.

How to rename voting disk name in oracle clusterware 11gr2
Hi:
I need change the name of voting disk at os level, original name is /dev/rhdisk20, I need rename to /dev/asmocr_vote1 (unix AIX), the voting disk is locate in ASM diskgroup +OCR.
Initial voting disk was: /dev/rhdisk20 in diskgroup +OCR

1. ONLINE a2e6bb7e57044fcabf0d97f40357da18 (/dev/rhdisk20) [OCR]
I createt a new alias disk name:
#mknod /dev/asmocr_vote01 c 18 10
# /dev->ls -lrt|grep "18, 10"

crw-rw---- 1 oracle asmadmin 18, 10 Sep 6 16:59 asmocr_vote01 ---> alias to old name, the new name.
After change votingn disk unix name, the cluster doesn't start, voting disk is not found by CRSSD.
-STEPS to start clusterware after changing the OS voting disk name are:
1- stop al nodes:
#crsctl stop crs -f (every node)
Work only in one node (node1, +ASM1 instance):
2- Change asm_diskstring in init+ASM1.ora:
asm_diskstring = /dev/asm*
3- change disk unix permiss:
# /dev->ls -lrt|grep "18, 10"

Edited by: 957649 on 07-sep-2012 13:11There is no facilty to rename a column name in Oracle 8i. This is possible from Oracle 9.2 version onwards.
For you task one example given below.
Example:-
Already existed table is ITEMS
columns in ITEMS are ITID, ITEMNAME.
But instead of ITID I want ITEMID.
Solution:-
step 1 :- create table items_dup
as select itid itemid, itemname from items;
step 2 :- drop table items;
step 3 :- rename items_dup to items;
Result:-
ITEMS table contains columns ITEMID, ITEMNAME -
Oracle RAC 11g. 3rd Voting disk mounting automatically without fstab
Hi,
We have a 2 node Oracle 11Gr2 Extened RAC database on Redhat Linux. We have a vote disk on each node and a 3rd vote disk on a separate site. The vote disk directories are NFS mounted. We have noticed that there is no entry in the fstab (on either RAC node) for the 3rd voting disk location, yet the directory is still mounted automatically on each RAC node at startup.
Can Oracle manage mounting the disks itself without using fstab? Oracle recommends using the fstab for mounting the directories and I have found nothing on Oracle mounting the directories in any other way other than fstab.
I am completely lost here. We need to do some configuration on the 3rd voting disk location and I need to find out how the disk is being mounted on the RAC nodes. Any help on this would be greatly appreciated. Thanks.
Rgs,
RobDid you check that rc.local file? Perhaps, the mount entries are in there.

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

How does oracle use voting disk?
How does oracle use voting disk? How does it do health check and arbitrates cluster ownership among the instances in case of network failures?
Why it must have an odd number ?
Thanks.Did they mentioned anywhere, that there should be odd number of voting disks? (it is just multiplexing).

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:
https://forums.oracle.com/message/9681811#9681811
You must configure your Clusterware same as RAC extended

Oracle 11gR2 RAC Installation - ASM Disks - Need advice on configurations
Hi Guys
How many disks are needed for Voting, Data, Log and Failover. Each should be in a seperate group or it can be in a single group of disk. Please advice. Thanks.Hi Friend,
Option 1 :
If Oracle Clusterware is used for implementing normal redundancy. We require the following for failover purpose also.
1. Two OCR files - 280 MB each
2. Three Voting Disks - 280 MB each
Total - 1.4 GB approx
Option 2 :
Oracle recommends that the disk used for the file system be on a RAID. When you use external redundancy the minimum requirement is One OCR and One Voting Disk with 280 MB each.
Choices :
1. External Redundancy - > Minimum No Of Disks (1) - > One OCR (280 MB) and One Voting Disk (280 MB) -> 580 MB
2. Normal Redundancy - > Minimum No Of Disks (3) - > Two OCR (560 MB) and Three Voting Disk (840 MB) -> 1.4 GB
3. High Redundancy - > Minimum No Of Disks (5) - > Three OCR (840 MB) and Five Voting Disk (1.4 GB) -> 2.3 GB
So, Choose based on redundancy...
Hope it helps..
Note : Use ASM for storing above files..
Thanks

Installing Oracle 11gR2 RAC Problem: ASM disks
Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer and according to the tutorial
http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
At the first time, I create VM rac1. While its OS Oracle Linux 5.6 is booting, initializing ASMLib Driver OK. I create 5 ASM disks successfully using the command:
[root@rac1 /]# /etc/init.d/oracleasm createdisk ASMDISK1 /dev/sdb1
Output: Marking disk "ASMDISK1" as an ASM disk: OK
Because the hard disk space of rac1 is not enough to install Database, I create VM rac1 again with bigger hard disk space (30GB). I do everything the same with that at the first time. But this time, While OS Oracle Linux 5.6 is booting, initializing ASMLib Driver failed. I create 5 ASM disks using the same command:
[root@rac1 /]# /etc/init.d/oracleasm createdisk ASMDISK1 /dev/sdb1
Output: Marking disk "ASMDISK1" as an ASM disk: failed
But when I use the command:
[root@rac1 /]# /etc/init.d/oracleasm listdisks
Output: ASMDISK1 ASMDISK2 ASMDISK3 ASMDISK4 ASMDISK5
My questions are:
First, can the 5 disks "ASMDISK1 ASMDISK2 ASMDISK3 ASMDISK4 ASMDISK5" be used correctly in spite of Marking disk "ASMDISK1(2 3 4 5)" as an ASM disk failed ?
Second, how to fix OS Oracle Linux 5.6 so that initializing ASMLib Driver OK while booting ?
Thanks.Folks,
Hello. The issue is solved by myself. Thanks. -
Reinstalling Oracle 11gR2 RAC Grid Problem - ASM Disks Group
Folks,
Hello.
I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer.
I have been installing Grid Infrastructure using runInstaller in the first VM rac1 from step 1 to step 9 of 10.
On the step 9 of 10 in the Wizard, accidentally, I touch the Mouse, and the Wizard is gone.
The directory for installing Grid in the 2 VMs is the same: /u01
In order to make sure everything is correct, I delete entire directory /u01 in the 2 VMs and install Grid in rac1 again.
I have understood it's not the right way to delete /u01. The right way is to follow the tutorial
http://docs.oracle.com/cd/E11882_01/install.112/e22489/rem_orcl.htm#CBHEFHAC
But I have deleted /u01 and need to fix one by one. I install Grid again and get the error message on step 5 of 9 as follows:
[INS - 30516] Please specify unique disk groups.
[INS-3050] Empty ASM disk group.
Cause - Installer has detected the disk group name provided already exists on the system.
Action - Specify different disk group.
In Wizard, the previous Disk Group name is "DATA" and its Candidate disks (5 ASMDISKs) are gone. I try to use a different name "DATA2", but no ASMDISKs come up under "Candidate disks". For "ALL Disks", all ASMDISKs cannot be selected.
I want to use the same ASM disk group "DATA" and don't want to create a new disk group.
My question is:
How to have the previous ASM disks and its group "DATA" come up under "Candidate Disks" so that can use it again ?
Thanks.Hi, in case this helps anyone else. I got this INS-30516 error too was stumped for little while. I have 2 x 2-node RAC which are hitting same SAN. The first-built RAC has a DATA diskgroup. When went to build second RAC on new ASM disk new DIskgroup (but same diskgroup name DATA) got INS-30516 about diskgroup name already in use etc. Finally figured out all that was required was to restrict diskstring using button in installer to only retrieve the LUNS for this RAC (this was quick and dirty - all LUNS for both RAC being presented to both RAC). Once diskstring only searched for the LUNS required for this RAC only, e.g.
ORCL:DATA_P* (for DATA_PD and FRA_PD)
the error went away.
I also have DATA_DR and FRA_DR presenting to both RAC. Apparently it scans the header and if it finds a diskgroup name that is already in use based on the diskstring scan it will not allow reuse of the diskgroup name since it has no way of knowing that the other ASM disks are for a different RAC.

Hi,
I am trying to setup Oracle 11gR2 RAC on Linux 5.4 64-bit machine. I have used OCFS2 for creating shared disks. Encountered with the following error message while installing "Grid Infrastructure".
[INS-30014] Unable to check wether the location specified is on CFS
[INS-40103] The installer has detected that the software location specified is on an OCFS2 partition.
[IS-41312] One or more locations specified for Oracle cluster Regestry (OCR) cannot be used.
[INS-41514] One or more locations specified for placing voting disks cannot be used.
-- At the time of configuration i have created 2 share disks, 1) For Oracle software 2) For voting disk and OCR
Provided the same details at time of Clusterware installation.
Please hel me.
Thanks,Actually for both Oracle software and OCR i have used OCFS2. bcz earlier in Oracle 11g1 RAC i did the same and able to do smooth installation Well, you can no more do that with 11gR2 and it's clearly mentioned in 11gR2 Error messages documentation that configuration of grid Infrastructure software for a cluster is not supported on OCFS2 partition. You'll need to specify a location that is not an OCFS2 partition.
Search for the error INS-40103 message at http://download.oracle.com/docs/cd/E11882_01/server.112/e10880/giinstaller_errormessages.htm
Cheers.
