Hi;
Pelase see:
Raw Devices and Cluster Filesystems With Real Application Clusters (RAC) [ID 183408.1]
For your future RAC related issue I suggest close your issue here as answered than move your issue Forum Home » High Availability » RAC, ASM & Clusterware Installation which is RAC dedicated forum site.

Raw Storage device for 10g RAC

Hi
What would be economical & of good quality RAW storage device for 10g RAC setup
Thanks
JIL

Sorry, but what do you mean shared networK?
Yes you need to ensure 2+ server hosts can access the storage array, but if you array can handle multiple direct connections then this is perfectly acceptable for RAC - this is Direct Attached Storage DAS.
Your original post made me think of NAS which may not be what you were meaning, but is how I read network device - NAS, NFS kinda thing - which is NOT a requirement for RAC.

There are a couple of errors that doesn't make the clusterware look fine.
There was no previous version of OCR. error:PROC-33: Oracle Cluster Registry is not configured
proprinit:problem reading the bootblock or superbloc 22
This could mean either your cluster registry file is corrupt or you don't have access to the raw devices. Check the access to the shared storage raw device is valid. If this is not true, then make sure you have all your backup files ready.

Raw device for oracle 8.1.7 on AIX 4.3.3

Hi there,
I am trying to use a raw device on AIX 4.3.3 for ORACLE 8.1.7.
I have created a raw device /dev/or_system
brw-rw---- 1 oracle dba 54, 1 Mar 04 10:44 or_system
but it is not possible to create a datafile on it :
SVRMGR> create database "GLM"
maxinstances 8
character set "WE8ISO8859P1"
datafile '/dev/or_system' size 150M REUSE
logfile

The ORA-27028 in exact this situation was reported as a bug in prior ORACLE Versions 8.0.4/ 8.0.5 and had
the bug no. 690228.
But we use as mentioned 8.1.7.
What do I do wrong?
Any suggestions are welcome.
Thank you
Gerhard

Each raw device you create is used as a single data file.
Eg mklv -y 'myfile' <vgname> <number of logical partitians>
Will have two special files associated with them /dev/rmyfile and /dev/myfile. The number of logical partitians will be the size of your datafile subtract 1 meg for overhead.
So, if you were addding the above raw volume to a tablespace, and the lp size was 32 meg, you would
create tabelspace tsname datafile '/dev/rmyfile' size 31 m;
Note the use of rmyfile not myfile.

All that is required from a system level are partitioned disks. Oracle will handle the configuration of the filesystem. Here are my steps to configure raw devices using LUNs:
--- PARTITION THE RAW VOLUMES ---
fdisk /dev/<disk>
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-512, default 1):<enter>
Using default value 1
Last cylinder or size or sizeM or +sizeK (1-512, default 512): >
Using default value 512
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
--- BIND PARTITIONS TO RAW DEVICES ---
Edit /etc/udev/rules.d/60-raw.rules and add:
# Define mapping of SCSI hard disks for Oracle Raw Devices
ACTION=="add", KERNEL=="sdg1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdj1", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdk1", RUN+="/bin/raw /dev/raw/raw3 %N"
# Define persistent raw device permissions
ACTION=="add", KERNEL=="raw*", OWNER=="oracle", GROUP=="dba", MODE=="0660"
--- CREATE THE RAW DEVICES ---
/sbin/start_udev
--- VERIFY RAW DEVICES ---
raw -qa
2. Update permissions of new devices
chown -R oracle:dba /dev/<disks>
3. Create links to device on /dev/oracle
# DETERMINE SCSI LINKS TO DEVICES

Yes you are right , I have to make to sure stock budget doesn't get credited.
If you remember in one of my other threads, i wanted to derive commitment item from Matl grp, it was for this purpose. I will derive commitment through matl group at the time of procurement / GR etc and assign a dummy commitment item to stock a/cs. Where as i will derive a consumption commiment item from consumption GLs.
Thank you

OCFS2 , ASM and Raw Device for Voting Disk and OCR

Dear all ,
My manager assigned me to establish a 11gRAC , 3 node on OEL. He likes to locate ASM with datafiles , at the same time, 2 OCR vol on OCFS2 and RawDevice respectively , 2 voting disks on OCFS2 and RawDevice respectively also.
This really annoys me .
Oh all experts, could anybody give me some advices ? Can those stuff be co-existed ?

Not a great idea to introduce additional s/w layers between the CRS software and its OCR and voting disks. If ocfs2 is for example used as a shared file system for these devices (files), then the ocfs2 cluster s/w needs to be up and running, the shared devices mounted, before CRS can successfully start. Thus any problem with the ocfs2 stack, will impact on CRS. Why? What does ocfs2 buy you in this regard? What are the benefits that justifies the increased complexity and the dependency of CRS on another s/w layer?
Fewer moving parts means less complexity, less stuff that needs to be configured and can go wrong.In fact, some users had perception that " Pay mroe so that Get more".

Configuring Storage for Clusterware on Raw devices

My proposed system is:
- Sun Solaris 10
- Oracle 10G RAC
- Oracle Clusterware
- Raw devices for Clusterware files
- ASM for database flies
Assume I have appropriately sized LUNs assigned on my SAN for OCR and voting disks. My question is, how do I configure the raw devices required for these Clusterware files?
I have read the Oracle RAC/Clusterware installation guide (Sun Solaris, SPARC), which goes as far as identifying the requirements but does not give the procedure. If I wish to use raw devices for ASM, it gives a procedure for creating partitions on the LUNs. Is anything like this required for the Clusterware files (OCR and voting disks)?

As far as I know, Solaris follows the traditional raw device definition, which basically says that a raw device is a disk or a partition on a disk that does not contain a file system (yet). Given your question, this would mean that any device that you can find that does not contain a file system would be a raw device.
Message edited here:
However, you need to find the right link to this device in order to use it as a raw or character device. Otherwise, the device would be used as a block device, which means it will be buffered.
On Solaris, those character devices should be listed under /dev/rdsk, while the block device would be listed under /dev/dsk. (Please, refer to: http://www.idevelopment.info/data/Unix/Solaris/SOLARIS_UnderstandingDiskDeviceFiles.shtml)
End of update.
Therefore, you have 2 options in your case. You can create LUNs in your storage that would be just suitable to host your Voting Disks and OCRs OR you can create a bigger LUN and put an OCR and a Voting Disk on this one, AFTER you have sliced the disk (LUN) using the format command.
There is only one thing to remember: If you follow Oracle's recommendation to use multiple Votings and mirrored OCRs, it would obviously be better that those devices do not all share the same LUN (for availability reasons).
Last but not least, you may want to have a look at the following forum for a similar discussion on using RAW devices under Solaris: http://forum.java.sun.com/thread.jspa?threadID=5073358&messageID=9267900
Hope that helps. Thanks.

Raw Device Validation Check for Name Failed..

Hi all,

Hi
this is how i have mounted the NAS...

Hi,
Please see these docs.
Note: 220970.1 - RAC: Frequently Asked Questions, How can a NAS storage vendor certify their storage solution for Oracle RAC ?
Note: 549089.1 - High Load Average When Using NAS (Network Attached Storage) File System For Oracle Applications Release 12
Note: 559518.1 - Cloning Oracle E-Business Suite Release 12 RAC-Enabled Systems with Rapid Clone
You could also verify the same with your hardware vendor.
Thanks,
Hussein
