ASM discovered an insufficient number of disks for diskgroup

Running RH4U3 and Oracle 10gr2
Every time I reboot my system, the minor number changed and i can't startup the ASM instance. Does any one know why this is happening? Any advise would be appreciated.
the minor number was 4 and 5, now after reboot i got::

ORA-15063: ASM discovered an insufficient number of disks for diskgroup

Hello DBAs,
I have encountered this problem. I am using storage vendor snapshot capability. On my first node, I have 2 disks for ASM diskgroups. ORCL:DATA belongs to DATA diskgroup and ORCL:FLASH belongs to FLASH diskgroup. After making the snapshots of these two disks, I mapped them to my second host which already has ASM instance. I ran /etc/init.d/oracleasm scandisk and listdisks I see two disks. But when I start up ASM instance I get this error:
SQL> startup
ASM instance started
Total System Global Area 130023424 bytes
Fixed Size 2019032 bytes
Variable Size 102838568 bytes

ORA-15032: not all alterations performed
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "FLASH"
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "DATA"
Of course, I have the asm_diskstring and asm_diskgroups parameter set in my init+ASM.ora file. The ASM version is identical across both hosts. I guess my question would be, is it possible to do this? Do I need to re-create the ASM disks using /etc/init.d/oracleasm? Any help is much appreciated.
Thanks,
TD

What is your configuration?
If you have AIX and EMC san, then refer to this metalink note: 467702.1
In my case, it was HP-UX and HP san EVA8200. But our problem was two different disks were presented to the two nodes, with same names by the unix admin/san admin guys.
Before they could figure out the problem, I had done a lot of research for few days to figure this out. Another problem I noticed in some cases was improper permissions. Either the db software owner didn't have permissions to the asm disks, or if the owner of both software was same, then the actual permissions/ownership of the shared raw devices was different on the two nodes.
Hope this helps. And I will appreciate once you fix the problem if you can also update this forum with your solution. That will help the community in future.
Thanks

ORA-15063: ASM discovered an insufficient number of disks for diskgroup "DB

Dear All,
we are moved our storage from hitachi to EMC . after come to emc no issue.
But few day before we are try to use old hitachi storage for our T&D,the same storage mounted in new server.
After that we are try to start the asm but it disk group not mounted .
It show following error....
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "DB01"
1) we are checked the 52 raw devices have oracle:dba permission we are verified.
2) all raw device can be viewed in v$asm_disk and state is normal.
3) we are tried asm_diskstring=* also
4) even it show same error.
1) My doubt is the asm meta data may be not correct how can i verifiy the the asm metadata and how can i resolve this asm error.
2) If i drop this asm diskgroup and recreate in same name and add all 52 disk to the group the data will be loss or not?
Thanks&regards

1) My doubt is the asm meta data may be not correct how can i verifiy the the asm metadata and how can i resolve this asm error.Asm metadata will get stored in asm_disks it's self. we cannot retrieve metadata unless you mount the diskgroup.Most probably these would be permission related of disks.
any pointings to alert log Errors of this operation.
>2) If i drop this asm diskgroup and recreate in same name and add all 52 disk to the group the data will be loss or not?
The header status of disks changes to FORMER ,once we fire drop on it.we cannot get back the data becase asm will format the disk after dropping.

ORA-15063: ASM discovered an insufficient number of disks for diskgroup "LO

After a reboot of the server, 3 of the 4 diskgroups mounted.
The one that did not mount contained my redo logs and controlfiles.
Select * from v$asm_disk does not show anything related to this diskgroup.
select * from v$asm_diskgroup does not show anything related to this diskgroup.
I can't start my databases.
oracleasm listdisk does not show my two "missing" disks.
oracleasm scandisk and then listdisk does not show the missing disks.
kfed shows these are part of the "LOG" group.
How do I get these back? I can't afford to lose the data that is on them.
Thanks
Dan

We rebooted numerous times and at one point had to unmount one of our ocfs2 file systems, so the /var/log/messages is full of entries for the past two days.
Is there anything specific I should be looking for in there?
you mentioned "recover the volume"....so do you think it's a problem on the san? how would you recover a volume?

I have lost my serial number and disk for lightroom 3

I have lost my serial number and disk for lightroom 3 and I need it - I have since upgraded to v5 but have gotten a new laptop and want to install lightroom on there. I have my order number from 2011 for v3 AD003916979. How can I get my old serial number?

On you other machine with Lr5 installed or Lr3 installed search for a file on you computer called "Lightroom 3.0 Registration" or "Lightroom 5.0 Registration". You may have to search for hidden/system files. These files contain your Serial Numbers in plain text.
Otherwise, if your order number is from Adobe you can log in with your account to see your purchased products or contact Adobe with that order number.

ASM best practices question: minimum disks per diskgroup

Our ASM storage is on a SAN, so all disks are external redundancy. Since the SAN is striping before it is presented to the host, is there a minimum number of disks per diskgroup that is recommended? We have a vendor that recommends a minimum of 8 disks per diskgroup and I'm trying to validate that. TIA...

Vendor might have suggested it depending on size of database or may be some grouping of tablespaces per diskgroup etc.

Error: An insufficient number of arguments were supplied for function

Hi ,
I changed the data source for a data set on my report . The data source is still pointing to same server and database but I am getting this error
"An error occurred during local report processing
Query execution failed for data set 'Data Set Name'
An insufficient number of arguments were supplied for function "
I checked the function number of arguments again and it was correct and even executed the function in the dataset query designer and it works fine.
any ideas for the reason for this error ?

Without seeing the query you use or function its hard to suggest.
See if parameter passed from SSRS has expected values. Is there some multivalued parameters involved?

Hi, I would like to install my Creative Suite 5.5 Design Standard - I got the serial number and disk, but you are asking for another product and serial number that I dont have? What should I do?

The serial number that you might have is an upgrade version & it will be asking for a previous qualifying version serial number.
The issue can be different too, please contact Adobe Support for resolution: http://adobe.ly/yxj0t6

Can't create disks for oracle ASM

Sorry for duplicating my post, I posted it in linux group, but don't know if I also can get help here.
Hi, all advanced,
I am installing oracle 10gR2 in Fedora core 4, and I prefer to use oracle Automatic Storage Management feature. Since oracle doesn't support FC4, I have to set up rRHEL4 kernel core to install ASM driver and configure it. The things went well until I want to create disks for ASM, for example:
# /etc/init.d/oracleasm createdisk DISK1 /dev/hda5
Marking disk "/dev/hda5" as an ASM disk: asmtool: Unable to clear device "/dev/hda5": Input/Output error
When I install the FC4, /dev/hda5 is only one of the partitions in the physical disk, not a full independent physical disk. Same to other disks that I want to put into ASM disks. I google the net but didn't find any similar problem happened to other players. So I need your help!

Hi Rafael,
What version are you using? I have had similar problems in the past. Worst case I had to recreate the widget and copy the coding across.
Can you send me the project file, I will understand also if you do not want to, I will try it on my machine.

Replacement Hard disk for Portege P2010 - Part number required

Can anyone tell me what the part number is for a replacement Hard disk for Portege P2010 is? It has the latest BIOS installed, can the HDD capacity be higher than the original 30gig?
Thanks
Martin

Hi
Like Ivan said, there are no officials documents about a max size of a HDD.
I assume that you can use a 40 GB HDD but Im not 100% sure if the bigger HDDs will work.
Please check this link:
http://www.sparepartswarehouse.com/devicetype-vendor-modelline-modelseries-partlist.aspx?devicetype=0&vendorlevel=ModelSeries &modelseriescatid=50972&partcatid=140744&filter =0
There you will find a 40GB HDD for Protg 2010.

Original driver disk for lenovo hardware

calling the support today, i could not believe the lonovo does not have an original driver disk for their hardware they are selling, and i dont mean the recovery cd that has an os on it. every other hardware manufacturer that I know of provides original driver disks; lenovo seems not to care.
for the stuff that I am doing, mostly clinical trials data analysis, i need a machine with highest level of integrity. all hell breaks loose when it later will be discovered that there was a glitch in the software/hardware. the first thing is the bios. what i need is an original cd, and original here means a pressed cd; not a burned cd, not one download over the internet, and no other amateurish solutions. i dont need the os that comes with the recovery cd, since i will be using linux (sled) anyway.
is anyone aware of where one could get such a thing, if at all?
thanks

Hi toby, welcome to the forum,
AFAIK the last T-series ThinkPads to have any cds delivered with them were the T22s, must be about what, six years ago? Since then ThinkPads have always had a recovery partition on the hard drive. It is possible to order recovery cds from Lenovo, or create them yourself, these will install your ThinkPad to factory state.
You can also find all drivers and utilities required for the ThinkPad in one folder, C:\SWTOOLS. Alot of people, (myself included), burn this folder to cds or a dvd. It does not however contain a copy of bios.
I'm afraid I don't believe such a cd exists, unless you create it yourself. (And of course all the latest drivers are available to download).
regards

How many disk for redundancy on Grid Infrastructure 11gR2 Installation?

I would like too know, How many least disk for normal and high redundancy ?
and please explain to me about structure of normal redundancy & high redundancy.

Redundancy Level      Minimum Number of Disks
External           1
Normal                2
High                3
If you only have a disk, means you will not be able to implement normal/high redundancy. In external redundancy ASM presumes the data duplication is taken care at a storage level (e.g. mirrored SAN etc.).
structure of normal redundancy & high redundancyRedundancy is actually a data duplication, so let say if a disk in a Disk Group1 fails, and there is a fail over Disk Group B, so ASM will continue operation.
Must read note for you..
http://download.oracle.com/docs/cd/B28359_01/server.111/b28301/asm002.htm#ADMQS12079
Extractions from the link..
Failure groups are used to determine which ASM disks to use for storing redundant copies of data. example, if 2-way mirroring is specified for a file, ASM automatically stores redundant copies of file extents in separate failure groups.

How can I make a bootable disk for Mountain Lion?

How can I make a bootable disk for Mountain Lion?

Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
Double-click on the InstallESD.dmg file to mount it on your Desktop.
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the mounted disc icon from the Desktop into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.

How can I create a start up disk for a old intel core duo running 10.5.8.. Computer works fine, but can't find install disk.

How can I create a start up disk for a old intel core duo running 10.5.8.. Computer works fine, but can't find install disk. Want to use internal disk drive or USD flash drive.

Try calling 1-800-676-2775. Give the serial number and thy *may* still burn you new install disks designed just for the hrdware in your system (for a fee, something like $160 per disk). *May* is only because they may not burn disks for Leopard anymore.
If they do not burn them for you, you can buy Leopard disks off Amazon or eBay for about $200.
Have you considered Snow Leopard?. Those disks only cost $19 (single user) or $29 (5-user license) through Apple by calling 1-800-MY-APPLE.
