I am using 11.2.0.1.0 on RHEL 5.4ASM is properly working on my machine. database is running from ASM. I want to configure additional oracleasm devices.command fails saying:
$ oracleasm createdisk ASMDISK08 /dev/xvd8
Writing disk header: done

I am creating asm diskgroup on loopback devicesHere are the configured loopback devices.

I am unable to understand where is the problem.
Suppose i have created a diskgroup using
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;
now i want to add more disk in diskgroup then we can use
ALTER DISKGROUP disk_group_1 ADD DISK
'/devices/disk*3',
now my question is
(1) in which failgroup thE Disk*3 will be added ?
(2) How ican maintain eqal no of disk with same size availble in each FAILGROUP for data mirroring or redundancy by ASM ?
i am adding luns to the asm diskgroups in 10g where to find the grid path in 10g .
in 11g i can find
/orainfra/11.2.0.3/grid/bin/amdu -diskstring '/dev/oracleasm/disks/DATCSLGGPA*' -dump 'DATCSLGGPA'
but i can't able to find in 10g .
After a power failure, I have now dropped disks in my 2 diskgroups DG_RACDATA1 and OCRVD.
Disks has been renamed and prefixed by DROPPED...
Their state is now "FORCING"
Mount status = missing
header status = unknown
Mode status = Offline
These disks was belonging to a failure group with redundancy so the cluster still works ...but I have lost the redundancy.
How to reuse these offline disk or confirm that what I plan to do is good:
Shall I put them online ? ALTER DISKGROUP DG_RACDATA1 ONLINE DISK DROPPED0000_DG_RACDATA1
Shall I drop them ? ALTER DISKGROUP DG_RACDATA1 DROP DISK DROPPED0000_DG_RACDATA1 FORCE
and then: zeroing them and readd to failgroup ? but how ?
One of my collegues created an ASM disk group with normal redundancy using 2 disks. But the disks are not of same size, one disk is 100GB and another one is 10GB. Now the usable space out of diskgroup is showing 55GB. When I checked the diskgroup properties it is showing 2 fail groups one is DATA1_ 0000 with 10GB and other is DATA_0001 with 100GB. My question is why it is showing 55GB as usable space? My assumption is as it is having 2 fail groups with different disks of different sizes. For the failgroup 2 even it is of 100GB size, in order to maintain the redundancy with other small FG(10G) it will consider only 10GB out of 100GB. So, the 2nd FG size also should be 10GB. So that the usable space should show as 10GB as opposed to 55GB (not (100+10)/2).

View 2 Replies View RelatedMy organisation is currently discussing different storage options for the database storage. Our production database is nearly 2TB and we do not want to continue with the existing NetApp storage (we use a 2 node RAC running 11.2.02 with nfs filesystem from NetApp filer).
We were looking at different options and came across Nimble Storage, they are very fast growing company aiming mid-range storage customers. The initial talks and demonstration looked very promising in terms of IO performance (they claim 40,000 - 60,000 IOPs for their CS400 series Nimble Storage array) and other options they are providing but we understand that majority of their customers are using it for VDI and other infrastructures.
They have demonstrated us using if for Oracle database with ASM storage over iSCSI LUNs. We are yet to do the POCs and benchmarking.
Has anyone come across Nimble Storage for running Oracle databases?

what is difference between san and asm because san also provide mirroring like asm,why we should go for asm.

How it spreads the database files across the disk group (Suppose i am having 4 disks in my disk group)?
We have a 2 node rac cluster running on HPUX Itanium platform running oracle rdbms 10.2.0.4 that is currently configured using raw devices for ocr, voting disk, and all of the datafiles. We have a business requirement that is mandating that we have to use TDE tablespace encryption and in order to do so we must now upgrade to 11g.We are in the planning stages for the upgrade process and I am just trying to understand or find out what is going to be the best method to move the data that is currently in the tablespaces on the raw devices over to new tablespaces that will be created within ASM and will be created as TDE encrypted tablespaces?Our database is about 1.8 TB and we have alot of fairly large critical transactional tables that support a 24 x 7 oltp environment that cannot afford downtime.

We are trying to increase ASM disk space and with respect to it when we are trying to allocate more space this question came across my mind. Now this was previously configured by my previous SA.

why are my LUN's showing different sizes on RAC and also the best way to allocate the space to the disks in the above scenario.
I'm using ASM on LUNs from an EMC SAN, fronted by PowerPath. Right now I have only one fiber path to the SAN, so /dev/emcpowera3 maps directly to /dev/sda3, for example. Oracle had a typo in what they told me to do in /etc/sysconfig/oracleasm*, so the scan picks up both devices.
#/etc/init.d/oracleasm querydisk -p ASMVOL_01
Disk "ASMVOL_01" is a valid ASM disk
/dev/emcpowera3: LABEL="ASMVOL_01" TYPE="oracleasm"
/dev/sda3: LABEL="ASMVOL_01" TYPE="oracleasm"
But I don't think it can be using both. How do I see which one it's actually using?
*They said:
ORACLEASM_SCANORDER="emcpower*"
ORACLEASM_SCANEXCLUDE="sd"
But I think that should be "sd*".
We have Oracle ASM and installing 11.1.0.6 on a new machine (eventually will apply 11.1.0.7 patchset). So we are on 11g R1 in production environments.

I checked various metalink notes, all settings are OK. We have ASMLib and i have configured ASMLib with the new disks prior to the ASM installation
Just to rule out the rootcause is with ASMLib , I have also disabled it. Still same problem. I ran the usual localconfig delete and localconfig add too.

I am not using RAC (to my knowledge), but I installed grid so I can use ASM with my RDBMS.

I added a new disk to a diskgroup. It starts to rebalance. However, I plan to drop the diskgroup anyhow and recreate it since I want to restore a database to it.(I shouldn't have added the new disk beforehand, my mistake) So now it's rebalancing and may take some hours.Can I drop the diskgroup now?I think there is no way to stop the rebalance?
View 2 Replies View RelatedBackground: We are migrating a lot of databases from one SAN appliance to another. We are doing this by adding new disks from the new SAN appliance to the existing disk groups, re balancing, removing the old disks from the disk groups, and then re balancing again.
Question: If I execute two ALTER commands with the same power on 2 or more separate disk groups, do both operations start executing right away? Or do they queue up and execute one after another?
I ask because we would like to queue up several re-balances so we don't have DBAs watching status bars all day.
