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
ASM Cache 25165824 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.

Problem with ORA-15063

Hi,
I've installed Oracle RAC (10g) on Centos 5.3 But after restart system, I can't mount ASM disk on second instance. During mounting I have such errors:
ORA-15032: not all alterations performed
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "DG1"
I found this tutorial http://askdba.org/weblog/?p=104, but I don't really know if my parameters are set correctly... Could anyone help me and explain what is wrong with my database? Screen from my architecture below:

Hi,
ORA-15063:
     ASM discovered an insufficient number of disks for diskgroup "string"
Cause:      ASM was unable to find a sufficient number of disks belonging to the diskgroup to continue the operation.
Action:      Check that the disks in the diskgroup are present and functioning, that the owner of the ORACLE binary has read/write permission to the disks, and that the ASM_DISKSTRING initialization parameter has been set correctly. Verify that ASM discovers the appropriate disks by querying V$ASM_DISK from the ASM instance.
And there is possible solution

Can you check what is the value set for the parameter "asm_diskstring"
Post the outcome of
sql>show parameter asm_diskNormally, if the disks were created using ASMLIB, then check out the location of the ASM disks at the location "/dev/oracleasm/disks" and if the disks are present at this location, then set the parameter "asm_diskstring" to the above path. The default value of this parameter is "ORCL:*"
asm_diskstring=/dev/oracleasm/disks

Any idea what it can be?

Hello Fred,
Did it happened only at startup?
When you try mount, the disks of DG are visible to second node?
Please provide more info about your env, EMC, NetApp, etc.

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...

We have a vendor that recommends a minimum of 8 disks per diskgroup and I'm trying to validate that. TIA...AFAIK, there is no such criterion for minimum disks in diskgroup. Vendor might have suggested it depending on size of database or may be some grouping of tablespaces per diskgroup etc.

ORA-00932: inconsistent data types: expected NUMBER got BINARY

ORA-00932: inconsistent data types: expected NUMBER got BINARY
Hi,
Could anyone help in resolving my problem?
I m developing cmp beans in Jbuilder X,
My database is Oracle 10g, running on Linux and Application server is Oracle10gAs. Running on Windows.
I can deploy my Entity EJBs OK and look then up using finder methods as long as Ive created the data directly in the database using SQL*Plus for instance.
In the database I have my primary keys defined as type NUMBER
In my EJB the corresponding number fields get mapped as java.math.BigDecimal.
which according to the Oracle JDBC specification is how they are mapped.
Problem:
When I try to create a new database entity through my EJB entity bean I get:-
Error "ORA-00932: inconsistent datatypes: expected NUMBER got BINARY".
The value of the number being used as the primary key in this example is 10.
Eg:-
BigDecimal pk = new BigDecimal(10);
TestBean test = home.create(pk);
The datatype in my EJB Deployment descriptor ejb-jar-xml <pri-key-class> is java.math.BigDecimal>
The jdbc driver defined in my application.xml is
oracle.jdbc.driver.OracleDriverand url="jdbc:oracle:thin..." in the connection.
Ive even tried mapping a datatype as described in the Oracle FAQs but this didnt work.
21.     I'm trying to deploy a CMP entity bean with a field type BigDecimal and the table creation fails with an error. How do I work around this?
You have to perform the following steps prior to deploy your application.
o     Define the mapping for java.math.BigDecimal in the database-schemas/oracle.xml as follows:
<type-mapping type="java.math.BigDecimal" name="number(20,8)" />o     Use this schema in your data-source as follows:-
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="OracleDS"
ejb-location="jdbc/OracleDS"
schema="database-schemas/oracle.xml"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="scott"
password="tiger"
url="jdbc:oracle:thin:@localhost:1521:DEBU"
clean-available-connections-threshold="30"
rac-enabled="false"
inactivity-timeout="30"
/>

Further clarification of my problem.
Originally I said the error occurred when deploying EJB's
Correction: I can deploy them OK on the application server However the Error message occurs when I try to create a new EJB entity, the only value required is the Primary key which I pass as type BidDecimal.
If I create entries directly in the database my EJB findByPrimaryKey can find entities OK.
But I cant create new ones through EJB.
What realy baffels me is why I'm able to read data through the connection but not write.
The datatype in my EJB Deployment descriptor ejb-jar-xml <pri-key-class> is java.math.BigDecimal>
The jdbc driver defined in my application.xml is
oracle.jdbc.driver.OracleDriver
and url="jdbc:oracle:thin..." in the connection.

ORA-02315: incorrect number of arguments for default constructor

I was able to register the XML schema successfully by letting Oracle creating the XML Types. Then when I try to execute the create view command the ORA-02315: incorrect number of arguments for default constructor is always raised.
I tried using the XMLTYPE.createXML but it gives me the same error.
Command:

p.fraction)
FROM peak p
WHERE s.sample_id = p.sample_id) AS PEAK107_COLL))

Can someone help me.

This example runs without any problems on 9.2.0.4.0. Which version are you running? And which statement causes the error message?

ADO Error: an insufficient number of arguments....

Im currently using Access 2000 which is connected to a SQL database. I have a query (Or View) that runs every month. The problem i had was i had to manually make some changes every month to get to the data i needed so i changed this View into a Function with a parameter so i can input the detail(s) i need and it will run correctly - this works so far but the original View was also used within other queries that were created. Now the problem i have now is some of the other views that are now connected with the newly created Function comes up with the error:
ADO error: an insufficient number of arguments were supplied for the procedure or function Name_Of_Function.
I called the newly created function the exact name as the original view to ensure i had no problems. Any idea of whats happening here and how to resolve?
Thanks

Heres the function i have:
Code BlockSELECT     TOP 100 PERCENT dbo.[Totals].User, dbo.[Totals].[Account Name], dbo.[Totals].Company, dbo.[Totals].Name,
                      dbo.[User].Amount AS [Month Amount], dbo.[User].Profit AS [Month Profit], SUM(dbo.[Totals].[Y Amount]) AS [Y Amount],
                      SUM(dbo.[Totals].[Y Profit]) AS [Y Profit], dbo.[User].Month
FROM         dbo.[User] RIGHT OUTER JOIN
                      dbo.[Totals] ON dbo.[User].[Account Name] = dbo.[Totals].[Account Name] AND
                      dbo.[User].User = dbo.[Totals].User
GROUP BY dbo.[Totals].User, dbo.[Totals].[Account Name], dbo.[Totals].Company, dbo.[Totals].Name,
                      dbo.[User].Amount, dbo.[User].Profit, dbo.[User].Month
HAVING      (NOT (dbo.[Totals].User = N'Temp')) AND (dbo.[User].Month = @Month)
ORDER BY dbo.[Totals].User, dbo.[Totals].Company
Where it states Month = @Month is where the problem is i think. This Function runs fine as i want it to. But when im in another view that uses this function it get the above error. The only way i dont get the error is when i type in the month then all runs fine - but i would prefer it to ask me what month i need the data for????
Thanks

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?

ORA-15124: ASM file name contain invalid alias name after creating standby
