Create diskgroup in ASM

hi,
i invoked asmca command in $prompt and i tried to create disk group....
i have two raw storage devices located under /dev/raw/raw1 and /dev/raw/raw2 .......
how can i discover those two raw devices and create disk group in ASM configuration
please help me......

with these two devices , i want to create asm with redundancy-normalYou can run DBCA and there you can select ASM option and you will see that it has detected your raw devices and now you can create the diskgroup with normal redundancy. Alternatively you can login to ASM using SQLPLUS and use following command to create disk group
CREATE DISKGROUP disk_group_1 NORMAL REDUNDANCY
FAILGROUP failure_group_1 DISK
    '/devices/diska1' NAME diska1,
    '/devices/diska2' NAME diska2
FAILGROUP failure_group_2 DISK
    '/devices/diskb1' NAME diskb1,
    '/devices/diskb2' NAME diskb2;Reference
http://www.oracle-base.com/articles/10g/AutomaticStorageManagement10g.php
and i need to disk-disk mirrorNormal redundancy is two way mirroring and same as your demand.
if i disconnect one disk and i connect to other server DB should be upYou mean you want to unplug this disk and plug into another server to create a copy of this database residing on this disk? Why going towards this complexity, simply create a clone of your database using other methods. I am not sure (probably you can't) you can plug this disk to other server and other ASM will be able to read this mirrored copy of database because metadata of this disk will tell ASM that this is a mirror of a normal redundancy and hence may not allow you to utilize this disk.

How to create a new ASM Diskgroup in Oracle 10g RAC?

Hi,
Our env is Oracle 10g R2 RAC on HP-UX. I want to create a new ASM Diskgroup. Please let me know if the following steps are ok to create a new ASM Diskgroup.
1. Ensure the new Disk is visible in both ASM instances in RAC (v$asm_disk) and the header_status is 'CANDIDATE'
2. From Node 1 ASM Instance issue the create diskgroup command.
SQL> create diskgroup DATA2 external redundancy disk '/dev/rdsk/c4t0d5';
3. Query v$asm_diskgroup and make sure the Diskgroup is created.
4. Mount the DATA2 Diskgroup from Node 2 ASM Instance.
5. Query v$asm_diskgroup and make sure the Diskgroup is visible from Node2 ASM instance.
6. Ensure the header_status is 'MEMBER'.
Rgds,

correct.
instead of using device file '/dev/rdsk/c4t0d5' you can create an alternate device file using mknod, which is called "asm_disk_xg" for example.

Hi,
I created new ASM diskgroup by using one of the RAC node through Grid control , it created new disk group successfully , I can see all the diskgroups in Grid control including newly created, but some how data is not moving into newly created diskgroup, all the diskgroups are mounted. Am i missing any post step , please help.
Thanks

Hi,
Data is not balanced accross diskgroups. It's balanced accross disks within a diskgroup. What exactly are you trying to achieve here?

How to add diskgroup in ASM on linux

Hi All,
I have installed oracle 10.2.0.4 through Oracle VM- template. I install this template on OEL 5 (oracle enterprise linux 5) update 2.
10.2.0.4 template is readily avaible which I just extract and run. It install 10.2.0.4 with ASM for single instance.
Now, I want to add more diskgroup as by default this template created two diskgroup in ASM, but when to go for path of that diskgroup it will showing only: ORCL:VOL1 as a "path"
query:
select path,redundancy,total_mb,free_mb,failgroup from v$asm_disk where mount_status='CACHED' and header_status='MEMBER' and mode_status='ONLINE' and state='NORMAL' order by path ;

how can I find on which physical path this diskgroup is created liek "/dev/xvd"...or something like this???
can any one suggest me how to add new diskgroup... I can't use GUI becuase its disable.

Setting up diskgroups in ASM

Hello -
I'm trying to setup diskgroups in an ASM instance, but get an error indicating the disks do not exist. I'm testing the setup of this using ASM on top of Unix file systems. I'm testing on Solaris 9. Do I reference a physical LUN on the SAN, or the logical Unix file system to create the diskgroups?
Thanks in advance!
Mike

Thank you for your response.
Here is the disk that I am trying to map:
/dev/dsk/c2t10d89s0 105433231 98527307 5851592 95% /u04
I set the asm_diskstring to '/dev/dsk/c2t10d89s0'
I then try to create the diskgroup as follows:
SQL> create diskgroup dgroup1
2 external redundancy
3 disk '/dev/dsk/c2t10d89s0';
create diskgroup dgroup1
ERROR at line 1:
ORA-15018: diskgroup cannot be created
ORA-15031: disk specification '/dev/dsk/c2t10d89s0' matches no disks
ORA-15025: could not open disk '/dev/dsk/c2t10d89s0'
ORA-15056: additional error message
SVR4 Error: 13: Permission denied
Additional information: 42
Additional information: 106104528
Additional information: 36
for the disk above, I have the following file system where I store Oracle data files:
'/u04/oradata/dbmike/phdv4'
I've also tried an asm_diskstring='/dev/dsk/c2t10d89s0:/u04', but still same error.
Thanks in advance for any ideas!

Creating diskgroups and failure groups on windows

Hi,
I have a Windows 32-bit with two drives of C: and F:. I have an Oracle database that I like to migrate to ASM. I ran the utility localconfig.bat with the add option which successfully started CSS services and installed ASM and started it up.
In DBCA I tried to create diskgroups but there is no way to do it. How can I create diskgroups and failure groups on windows?

You have to use the ASMTOOLG (or asmtool) program to "mark" the disks for use with ASM. Once done, DBCA should recognize the disks.
You might check out Julian Dykes powerpoint on installing RAC and ASM on Windows for more helpful info.
Cheers!

How to create database with ASM

HI
How to create database with ASM?
I install vmware workstation on window XP .On virtual machine install Linux 5 enterprise (Oracle) install.
I install oracle DB software only. Also make 3 disk for ASM .
1 -- When I want to install oracle DB with ASM . In this process candidate disks not show . Why?
How I can see disks ..
so I simple install oracle DB software only.
2 -- Now I want to create database with ASM by DBCA .
What process I will follow ?
Please guide me
Thanks

Hi
Steps to create database with ASM.
1.Install oracle binary with active CRS(For single node installation CRS is activated when you run root.sh) .
2.Create disk without file ssytem.
3.Assign disk to raw .
4.Change owner and permission to raw devices.
5.Configure ASM manually or USing DBCA.
Manually ASM Configuration.
a.Create initialization parameter file and password file.
b.Mandatory parameter is "instance_type=asm" as per your need configure rest of parameter like db_cache_size,large_pool_size,processes,remote_login_passwordfile,shared_pool_size etc..
c.To discover disk configure "asm_diskstring=/dev/raw/raw*"
Using DBCA to configure ASM.
1.In storage type section choose ASM.It will ask for password of sysdba in 10g.
2.ASM configuration window will open -> here it create disk group -> it shows all available ASM candidate disk automatical -> choose normal redundancy,external redundancy or high redundancy.
ASM disk also can be conbfigured with ASMLIB .
If ASM disk is configured you can start asm instance in nomount state and query to v$asm_disk to see all candidate disk.V$asm_disk only shows disk which is configured in asm_diskstrings.
Hope this will help U,
Tinku

Oracle Metalink solution was to

Note: Recreate the raw devices is required in order to remove completely the ASM metadata.

No member Disk displayed while creating Diskgroups for new ASM instance

Have installed CRS
Have installed DB software
Invoked dbca to create asm instance
Instance created
Disk members not displayed for creating disk groups
OS is Hp ux 11.23

The most likely reason on HP/UX is the permissions on the devices, all the devices to be used by ASM (including the devices for alternate paths) should be set to oracle:dba (or what ever user ASM is installed under) and chmod to 664.

Can't create database using ASM (SOLVED)

Hi all
I'm trying to use ASM for the first time, on Oracle 10.2.0.1 on Solaris x64.
I have installed the ASM instance into /opt/oracle/asm/10.2.0 and created disk groups. I have cssd running OK. I am able to start and stop the ASM instance without problems, and I can select from v$asm_diskgroup to confirm that disks are mounted OK.
I have then installed Oracle EE separately into /opt/oracle/server/10.2.0. I first did a software only install, and now I am trying to create a DB.
The problems come when I try to use this ASM instance to host a new database. I first tried to use DBCA to create a new database, but on database creation I got the following errors:
ORA-00200: control file could not be created
ORA-00202: control file: '+DBLIVE1'
ORA-17502: ksfdcre:4 Failed to create file +DBLIVE1
ORA-15001: diskgroup "DBLIVE1" does not exist or is not mounted
ORA-15055: Message 15055 not found; No message file for product=RDBMS, facility=ORA
ORA-01031: insufficient privileges
I then told DBCA just to create the DB creation scripts, and I tried manually running these with SQL*Plus.
When doing it with SQL*PLus, I initially got the same error as shown above. But then something changed (sorry, not sure what), and now the error I get is:
CREATE DATABASE "NEONREL1"
ERROR at line 1:
ORA-01501: CREATE DATABASE failed
ORA-00349: failure obtaining block size for '+DBLIVE1'
ORA-01031: insufficient privileges
I've put some debug info below, showing me succesfully connecting to the ASM instance and then attempting to create the DB using the db creation scripts, showing the error at the end. You can see that the oracle OS user is able to connect fine to ASM, then I swithc ORACLE_SID and ORACLE_HOME to the EE install and try to create the DB, at which point it apparently can't connect to ASM any more.
I've tried the DB creation many times, and in between attempts I completely empty $ORACLE_HOME/admin/<dbname> and delete the files related to the attempted install from $ORACLE_HOME/dbs/ . I've also stopping/starting ASM, rebooting, and I've done the install of ASM and EE a couple of times over in case I made any mistakes in my earlier attempts.
Any help would be much appreciated!

Update: I've worked out the difference between the two sets of errors I get.
The basic error is this:
ORA-00200: control file could not be created
ORA-00202: control file: '+DBLIVE1'
ORA-17502: ksfdcre:4 Failed to create file +DBLIVE1
ORA-15001: diskgroup "DBLIVE1" does not exist or is not mounted
ORA-15055: Message 15055 not found; No message file for product=RDBMS, facility=ORA
ORA-01031: insufficient privileges
However if my init.ora contains the line:
control_files=/opt/oracle/server/10.2.0/dbs/cntrlNEONREL1.dbf
then I instead get the second error:
CREATE DATABASE "NEONREL1"
ERROR at line 1:
ORA-01501: CREATE DATABASE failed
ORA-00349: failure obtaining block size for '+DBLIVE1'
ORA-01031: insufficient privileges
So basically these must be the same error, just in the second case I'm not trying to put the control file on the ASM so it fails at a different point.
But both errors must be because of the same cause, I suppose.

Create space in ASM Instance

Dear All,

Data Guard: 10g R2 Database using ASM (OS: Windows Server 2003)
We are getting the following errors in the alert log file of ASM Instance (Data Guard) - Data Gaurd mode is 'Max Performance':

Uopn checking the disk group DG_DATAFILES_AND_FB, free space is 0.
What are the possible options to create more space on this disk group? Can we delete some files safely without any impact (for example: Archive logs which have been applied to database)?
Thanks for your advice.
Regards,
Muhammad Riaz

Hi,
First you can add more disks to the diskgroup so you can get more space, ASM will do rebalance once new disks added.
Second, It seems that your archivelog in dataguard were not deleted after being applied. You can delete the applied archivelog in dataguard, use RMAN is the best option
Hope this helps
Cheers

Presently There are 3 diskgroup (Filesystem) in my DB suppose
+ABC
+DEF
+GHI
Now I want to add a new Diskgroup (File system)
Say
+XYZ
and I want to tranfer some file from OS to ASM so that these files are stored in
+XYZ
I m new to ASM plz suggest me in detail.
Thanks and Regards,

It depends on the type of file you are talking about, if an spfile, you can use a SQL command to add it in if the database already exists:
SQL> create spfile='+XYZ/dbname/spfileDBNAME.ora' from pfile='/home/oracle/initdbname.ora'
For other file types like datafiles, controlfiles, etc. you should use RMAN to move them from a "real" datafile into ASM:
RMAN> restore controlfile from '/oracle/product/admin/${db}/control01.ctl';
- take tablespace test offline first then...
RMAN> backup as copy tablespace 'TEST' format '+XYZ';
RMAN> switch tablespace 'TEST' to copy;
- then set the tablespace online
If non-Oracle files, it is possible to put them in/out ASM using XDB and FTP, but why?
Cheers!

Createing ACFS in ASM

Hi,
I am going to create ACFS filesystem in ASM having 2 node RAC 11.2.0.2.
I could get the option of ASMCA which will create ACFS file system on disk group. Which looks very straight forward.
But when I gone through some docs on ACFS [command line] it says to create the volume first [which is ADVM feature] and then create ACFS using ASMCMD>mkfs. I could not understand the why do we have to create volume in order to create ACFS? Also gone through the ADVM docs but did not understand what exactly it is and how it works?
Is the volume created using ADVM is the logical structure? Becuase when I created volume using ADVM I could not do CD to particular volume.
Can anyone explain the same to clear my fundas.
Thanks...

Hi,
think of ASM as a logical volume manager.
Like with every volume manager, you have to first create a volume, before you can put a filesystem onto it.
It is the same here: You first have to create a volume inside your ASM diskgroup, that this volume gets "exported" to the OS. After you created a volume, you will find a volume under /dev/asm/<name>.
This volume than can be used, to put any filesystem onto it, whatever you want.
E.g. ext3. Or better the ACFS filesystem.
Filesystems are formatted using mkfs (make file system command) from linux.
In the special case of ACFS it is mkfs.ext3 (which by the way is not an asmcmd command, but a generall linux command).
Now if you create ACFS via asmca, then the volume is created under the cover automatically. But if you look you will find the volume listed under the volume tab of ASMCA.
