SAN for ocr and vote file for Linux RAC

Hi Experts,
Based on Oracle document, i have to create 2 devices for the OCR and 3 for the VOTE in RAC.
However, my boss think SAN maybe mirroe OCR and Vote file. It is enough for 1 location in SAN storage. It does not matter how many driver sidplay for user.
Actually it is only one SAN in back side.
Any Explain for OCR/VOTE file in SAN?

The idea to have these multiplex copy is to reduce the single point of failure, non the less, that's reason you build RAC in the first place isn't?
So if it's possible you'd better have redundancy on physical disk level (LUN etc) then logic level (volume, partition etc) then file level.
Well I agree modern SAN are pretty reliable and had built in redundancy on physical and logic level, but if you only have single vote disk and OCR, your RAC is going to fail right away when vote disk and OCR has problem. The chances are if your OCR and Vote disk has logical corruption, the corruption is going to populated to your mirrors. Even if your mirror is good you still need to get mirror copy to replace working copy and restart cluster during the time your RAC is offline.
With more than one OCR and voting disk, your RAC is likely to survive single OCR/vote disk failure, so you can fix the problem while RAC online.

Commands for OCR and Voting File backup Restore?

We have 2 node rac instance on 64-bit win2003 with three diskgroups DATA, BKUP, +FRA.
We have ordered for new servers till then I will not have any test instance but only the production to work on.
I am taking care of db files, ctl, spfile, arcivelog files through RMAN.
The voting file and the ocr file is on raw disks.
I have gone through the rac material but My request is somebody please compile the way and command to backup my ocr and voting file and in case of loss what are the commands to restore the files?
Thanks in advace.

Recover OCR and VOTE disk after complete corruption of ASM disk groups.

Hi Gurus,
I am simulating a recovery situation to perform recover of OCR and Vote files after complete corruption of ASM related disks and diskgroups. I have setup my environment as follows:\
Environment: RAC
OS: OEL 5.5 32-bit
GI Version: 11.2.0.2.0
ASM Disk groups: +OCR, +DATA
OCR, Vote Files location: +OCR
ASM Redundancy: External
ASM Disks: /dev/asm-disk1, /dev/asm-disk2
/dev/asm-disk1 - mapped on +OCR
/dev/asm-disk2 - mapped on +DATA
With the above configuration in place I have manually corrupted +OCR, +DATA diskgroups with dd command. I used this command to completely corrupt +OCR disk group.
dd if=/dev/zero of=/dev/asm-disk1. I have manual backups as well as automatic backups of OCR and Vote disk. I am not using ASMLib.
I followed this link:
http://docs.oracle.com/cd/E11882_01/rac.112/e17264/adminoc.htm#TDPRC237
When I tried to recover OCR file, I could not do so as there is no such diskgroup which ASM can restore the OCR, Voting disk to. I could not Re-create OCR and DATA diskgroups as I cannot connect to ASM instance. If you have a solution or workaround for my situation please describe it. That will be greatly appreciated.
Thanks and Regards,
Suresh.

Please go through the following document which have the detailed steps to restore the 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 vote disk Allocation for shared raw storage with Solaris 10 questio

Hi all,
Current environment is Solaris 10 SPARC 64 bit OS with Hitachi SAN for shared storage and Sun E6900 servers.
For Oracle 10g RAC (10.2) and ASM, I am setting up the vote disk and OCR files on shared raw storage area network.
Assume that I have a 35Gb LUN carved out on raw device for the vote disk and OCR for a 2-node Oracle 10g RAC cluster and since the vote disk and OCR only require 120MB of storage, is there a way to use only a 120MB slice from the LUN or do I need to allocate the entire LUN/raw device to the vote disk?
I am looking for a way to avoid wasting space for the OCR and vote disk with my 10g RAC cluster and we are using raw devices and Oracle 10g RAC Clusterware with Veritas filesystem for the disk management. Can I have several slices on Solaris 10 with raw shared storage (Hitachi) to triple mirror my OCR and vote disk files?
It seems odd to have to use an entire 35GB LUN just for 2 small files: vote disk and OCR. Is there a way to partition a 120MB slice on one of the devices and allocate the rest to ASM?

Hi
In our RAC env.
we have 1GB LUN for OCR and Voting Disk and 100GB LUN for ASM disk. we have 4 Node RAC env on AIX with 2 SAN storage on Hitachi system for our Application.
we keept 1st Voting diks on SAN-1 2nd Voting Disk on SAN-2 and third voting on SAN-3.
OCR disk on SAN1 and OCR_MIRROR Disk on SAN-2.
we have ASM DIsk with Normal Redundancy . Failure Group 1 on SAN-1 and
Failure Group 2 on SAN-2

Move OCR and Vote Disk to a new SAN

Hi,
Can you guys help me with some links/documents for moving OCR and Vote disk files from old SAN to new SAN.
Both SAN will have ocfs2 formatted 3 partitions on which ocr and votedisk will be placed (normal redundancy).

Thanks for the reply, but all the examples were showing either ocfs2 to ASM or raw to ocfs2. could you just point out the high level steps for moving 3 ocr & votedisk files from one san to another(ocfs to ocfs).
Hi Ajay,
Steps will be same . It doesnt matter whether it is raw to ocfs2 or ocfs to ocfs.
There will be change only how do you assign storage for OCR/voting disk.
I have another doubt that, i already have 3 ocr files, can i add more ocr files pointing to another mount point? the same goes with votedisk.
You can use replace option so there is no need to add 4th OCR disk.
i found steps in one of the website: i have few doubts in it, could any one clarify it...All the steps seems to be fine.
Moving OCR
1) create mount point(new san - /u05) in all nodes
2) precreate ocr files in new mount points (i am not sure how to do it? is it just touch and filename, its a ocfs2 file system)on ocfs you need to create file as below :
dd if=/dev/zero of=/ocfs/OCR/ocrnew.dbf bs=1M count=128
Also I would suggest to have a look at :

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:

Virtualbox - install build and header files for your current kernel

I have initially installed virtualbox before upgrading the Arch
Also took backup of the kernle before upgrading since kernel26 2.6.30 is having problem with virtualbox
After upgrading I have configure the grub to use the previous kernel i.e 2.6.28
Later installed xorg and want to install the video drivers from VBox additions
but running
sh VBoxLinuxAdditions_x86.run
i get the following
install build and header files for your current kernel
The current kernel version is 2.6.28 Arch
What are the build and header files I have to install or search with pacman
And since i have upgraded the system will I able to look up the header and build files needed for kernel 2.6.28

dmartins - he's talking about his kernel's headers, not the kernel-headers package - they are two very differnet things.
sant527 - when you backed up the 2.6.28 kernel, did you remember the files in /usr/src/linux-2.6.28-ARCH/ ? They're what VBox is looking for.

How does one change the font size for folders and/or file lists in the '''Bookmarks''' Library?
Since the upgrade to version 9.0.1 of Firefox, the Bookmarks feature changes are confusing me. They seem to be confusing themselves as well. The list of bookmarks has changed. The font size is so small that my aging eyes cannot read it without fogging the screen with my breath. Some folders are out of alphabetical order (where I know they were previously good), and some are missing altogether (folders to which I frequently add references).
As for missing or deranged files or folders, was there something that I should have done or now need to do to recover those after the upgrade (or before)?
With regard to font size,
1. there is no “Edit Bookmarks” or like option to edit the list in this version
2. the “zoom” option in the “view” list of functions is greyed out when in “Show All Bookmarks” window
3. expanding the browser window has no effect on font size
4. “Preferences” settings for font size has no effect in that window either, including advanced settings
5. “Help” offers none that I can find.
Can any of you Help?!?

Maybe this extension helps:

Hi Craig
Unfortunately, in your case, there isn't really a way to separate them as far as I can think.
You could try restoring from a backup, and choosing an older backup perhaps

--Quick Guide for flashing BIOS, provided by MSI--
1. Create a MS-DOS boot diskette, then copy the the .exe and the bios file to the floppy disk. Both of these files can be found in the package you downloaded.
2. Press "Delete" and go to BIOS setup while computer bootup.
Check BIOS advanced features and see if BIOS flash write control is enabled
(This option must be enabled. If you can not find this setting, it means the BIOS can be
flashed.)
3. Boot from MS-DOS boot diskette and get a:\> prompt.
4. Type "", then press ENTER
5. The flash program will then ask "Do you want to save BIOS?", please press "N" for no. The when you see Press 'Y' to program or 'N' to Exit, please press "Y" to continue.
6. After flashing complete, remove floppy and reset the system .
7. Press DELETE or F1 when prompted at first reboot after flashing.
8. Load BIOS optimized defaults, then save settings and exits.
Drivers & Needed Files:
(Note: All these drivers are for Windows XP.)
Leaked Nvidia nForce3 Chipset Drivers Version 4.40
(Please use at your own risk, these are LEAKED drivers. Password for the .zip file is "ocworkbench rules". Also, you will need to rename the WinXP_2K folder in IDE to either WinXP or Win2K else the installer doesn't pick it up.) Thanks for the link Wonkanoby!
*NEW* Leaked Nvidia nForce3 Chipset Drivers Version 5.03
More leaked drivers? Seems some parts of the drivers are older and some are newer.
1. Windows XP Service Pack 1A (Web Install) -or- Windows XP Service Pack 1A (Full Install)
2. Microsoft DirectX 9.0b (Web Install) -or- Microsoft DirectX 9.0b (Full Install)
3. Nvidia nForce3 Chipset Drivers Version 4.24
4. AMD Athlon 64 Processor Driver Version 1.1.0.14
5. Nvidia Video Card Driver Version 56.72 -or- Omega Nvidia Video Card Driver Version v1.5303
(The Omega drivers are third party drivers optimized for gaming, most prefer these over the standard Nvidia drivers.)
5. ATI Video Card Driver Version 4.7 -or- Omega ATI Video Card Driver Version 2.5.51
(The Omega drivers are third party drivers optimized for gaming, most prefer these over the standard ATI drivers.)
6. Onboard Sound Driver (Realtek AC'97 Audio Codec) Version A3.61
It is HIGHLY reccomended that you install the drivers/needed files in the order listed above. Please note that there are two #5's because you either install one or the other depending on your video card, do not install both of them.
You will come across a problem here though. You can't install the chipset drivers without installing the Windows service pack and DirectX first, but the Windows service pack and DirectX installs need the internet to download files and you won't have working internet until you install the chipset drivers. Here's what I did to get around this. Instead of downloading the web install versions of Windows service pack and DirectX, download the full version and and put them along with all the other drivers on a backup hard drive or burn them to a CD, this way you will have all the drivers you need when it's time to install them and none of them will require the internet to download files.
Another note when installing drivers. Apparently the Nvidia chipset drivers also come with drivers for the onboard sound, but people seem to agree that the Realtek onboard sound drivers are better. When you are installing the Nvidia chipset drivers, just be sure to uncheck the box for sound drivers when it asks you which drivers you would like to install. Now you can safely install the Realtek drivers without any chance of conflicting sound drivers. Thanks for the tip Wonkanoby!

You CAN install the nforce drivers BEFORE installing SP1. The only requirement to install the nforce drivers is DX9.
So is SP1 still recommended to install before the nforce drivers?
The installer still reccomends to install it beforehand for full USB 2.0 functionality... I would have put what you said in there but I wanted to keep it as simple as possible.
oh. IIRC the installer just says USB 2.0 will be fully functional after SP1 is installed. So after you install SP1 you go into device manager and u click update driver and it will auto search and update the driver.
Simplicity-wise, i guess its pretty much equal. It might take less preparation to just copy DX9 full onto a CD and install that first, then nforce driver, then right away you have yoru internet connection.
but i dunno.. i guess i will try it your way this time when my RMA"d board comes.
i will be fomratting and doing a fresh install later on today and will let you know if i come across any problems
