• How to increase space in the ASM disk groups?

  Hi all

  I'm a newbie DBA in my team and today morning received an alert of OEM which:

  Target name = + ASM_ZEUS.techiebros.com

  Message = disk group DATA requires rebalance because at least a disk space is low.

  Any solution?

  To fix this, you can run this command: Alter diskgroup ASMDB add drive "here, the way of the new disk" Rebalance power 4 WAIT;

  After that, you can see through the v$ asm_operation;

• Add more space to the ASM disk group

  Hi all

  I am new to the DBA role and also in a process of learning. I need your help in putting a space at the ASM disk group. My VMware admin will add disk space to the virtual machine, and then the Linux admin will add space on Linux servers. Finally, I think I need to rebalance the database disk group to view the extra space. I'm not sure of what all the steps involved in this process. I like to read the Oracle Documentation, but I'm blurry and hesitant. Please let me know the steps to follow to add the ASM disk group space.

  We use

  Oracle DB version 11.2.0.3.0

  Linux version: 2.6.18 - 238.12.1.el5

  Thanks for your help

  No....

  You don't need any instance restart. More when you add a disk to a diskgroup, all rac nodes can see.

  just...

  You should add a node and watch v$ asm_operation...

• A question about the use of disk space free on a RAID 10 for ASM?

  Is it possible to install/configure 11gDB under the CARS using left over 300 GB of disk space.
  
  I have all my drives configured in RAID 10 and I have 11g THAT RAC installed. I uninstalled RAC and database and then added the required RPM (ASM library and drivers).
  
  Successfully installed the RAC and then proceeds to installation and configuration of 11gDB for ASM using the available disk space.
  
  Is this possible? I get the error message: 11g DB intalled on RAC1 ASM cannot be used until the Oracle CSS service is started.
  
  Thank you

  You get this because CSS is not started, and ASM, it needs.

  We had the problem of our self

  above default partition take slice 0

  We see link below

  Create the ASM Partitions in Solaris and add them as records of ACEs

  In architecture, Sparc, solaris disk is subdivided into 8 slices.

  This is the current configuration of these eight slices:

  slice 0: contains the files and directories that make up the operation

  System *.

  Unit 1: Swap, provides virtual memory or swap space.

  Unit 2: refers to the disk set, by convention. The size of this

  slice cannot be changed.* *.

  Unit 3: / export, holds different versions of the operating system.

  Unit 4: / export/swap. Provides virtual memory space for the customer

  systems. ***

  slice 5: large chocks software added to a system.

  Unit 6: / usr. Contains commands for operating system - also known under the name

  executables - designed to be run by the users.

  Group 7: / home. Contains files created by users.

  * Cannot be used as ASM disk. The use of this installment involves alteration of the disc

  and can make the disc unusable.

  * Should not be used as ASM virtual disk, slice refers to the entire disk

  (Including the partition tables).

  Is the range recommended to use for ASM disk.

  in accordance with the recommendation of the DSO we had used unit 4 the same

  so we had to diagnose details and came to know that must be used

  Hello

  Unbalanced disc can cause the missing disk free space does not allow to make any allocation to a disk group because each file should be evenly distributed across all disks by ASM political stripping.

  Configuration asymmetric discs and some operations on ASM disks can create this type of problem. Frequently, the problem must be resolved after a succesfull rebalance as much as all the drives have the same storage capacity, and there is no underlying hardware problem.
  The most common reasons may be the following:

  1 - the capacity of the disks within the ASM diskgroup are different
  2 - ASM instance is shutdowned normal/immediate before rebalancing is complete.
  3-disc is a FALL / HUNG State
  4. after an order to add disk rebalancing is still in place

  You can also try:

  ALTER DISKGROUP FRA CHECK ALL REPAIR;
  

  PS: Make sure you have these files on FRA was backed up somewhere safe.

  I started to go into the config and discovered that it didn't load basic disks to ASM data on local hard drives that were bought for her. they were loaded in our SAN storage...
  I need to move the disks local ASM of our SAN to hard drives...
  
  NOTE: The space used is small... but more than the local disk space is space on the SAN... If the size of the readers will have to be reduced...

  but I wanted insurance with people with experience as you go this drive on differnet LUN will not impede performance.

  A LUN is a logical unit - it may be a single physical disk. It may consists of 20 physical drives. If the LUN itself does not determine the performance. Performance is determined by the parts in movement under it.

  Multiple LUNS to the same diskgroup using or the volume of file system is a common practice. If this would be a problem (performance or otherwise) depends on the cloth under the LUN.

  For example, a logic unit number could be RAID5 and another logic unit number can be RAID0 + 1. Mixture of different RAID levels is not really a good idea.

  A LUN can be a storage on a San and accessible via the fiber channel. Another logic unit number could be an iScsi device, accessed through intellectual property. Mix very different storage architecture and storage protocols are not a good idea.

  A LUN can be RAID0, through fiber double channels connected to a switch, for the storage of 1 storage server. Another logic unit number can also be RAID0 and accessible through the same fiber channels and switch, but since the storage server 2. Whereby the RAID levels are the same and the storage Protocol and infrastructure the same - and that will not only make a compatible mix, but can actually increases the redundancy if you use these as disk mirrors ASM (which means that ASM can lose the server storage 1 or 2 and still works).

• How to add ASM Disk to Disk Group that is displayed as a MEMBER?

  Hello
  
  We have a Production Oracle RAC on HP - UX. We have two disk groups for Arcive (ARC_DISK) and the other for Database (DATA_DISK).
  
  Today, I wanted to add another 200 GB of disk space to DATA_DISK group.
  
  I opened DBCA and did not find the new drive in the option "show the candidates." But after that the administrator modified Unix ownership and permission to drive, it has been shown in the option "show the candidates." I chose this drive and continued but got an error later because we changed the ownership and permission of the 2nd Unix server. After doing this, when I opened DBCA to add disk, nothing does not appear in the option 'Show candidates', but when you click on "Show All", the new drive is listed as MEMBER (header status) but not assigned to a disk group.
  
  I would like to know how to distribute this disk (which is already displayed as a MEMBER) to DATA_DISK - ASM diskgroup. It is a system of production database.
  
  Rgds,
  
  Thiru

  Good to hear that.

• Question about the use of size mixed with ASM disk groups

  I support a RAC 10 g 10.2.0.3 running and using ASM cluster. We currently have a group of data disks, which is 600 GB in size, consisting of 3 individual raw disk 200 GB devices. The RAC cluster runs on a server pSeries IBM using AIX 5.3
  
  I need to add more space, but the system administrator can give me only 100 GB in the new raw device. What will be the impact, if any, the addition of this feature of smaller crude disk in the same data ASM disk group? I understand that ASM is trying to "balance" the general use of each raw device. ASM still works very well, or will he constantly try to rebalance the disk group because the a raw device is only half of the other three? Any help and advice would be greatly appreciated. Thank you!

  It works, I do the same thing in a production database. What happens is, asm will distribute data on the size of the disks. 200 GB drives will get two times more data than the 100 GB drive. The downside is that it will also result in an unequal distribution of the IOPS / s: adults discs will be achieved more often.

• ASM disk - based SAN LUN expansion

  Hi all
  I'm learning a bit about the ASM and best practices to follow properly set up/use it at its best.
  
  Using an external FC SAN storage, if I create a logical volume with a LUN number and expose this LUN to my server ASM, I can see it properly and add it to an ASM disk group.
  
  So far so good. After that, if I develop this LUN on the external storage (using the tools), I'm not able to see the new space of the DSO. Looks like Oracle somehow "partitioned" originally the LUN when I first added it to the instance of the DSO, and after the "marking" it, even if I increase the Volume, the "expansion" is not seen.
  
  Is there a way to tell ASM as ther IS actually more space available? If I "fdisk-l", I see the amount of space on the device. But the 'blocks' are always the old value...
  
  I know that the creation of another logic unit number and adding to the disk group, there is no problem, but I would rather be able to expand an existing LUN on my external storage to create new LUNS on it all the time... Please help me understand if what I have in mind is correct or not on a best practices perspective.
  
  Thanks for any help.

  Yes you're right. Add the 20 GB lun, you can with 0 downtime and then remove the old 10GB of the diskgroup lun (assuming that you don't change the 10 GB to 20 GB :)) If you hold rebalance low power, Re-balance I/O will be even not worth the performance system IO too muchl.) But the problem here is that hesitate to use only a single lun 20 GB as the entire disk to ASM diskgroup. If you increase the number of LUNs (disks asm) even by creating separate volumes on the same physical disks you will increase the number of logical I/O paths which contributes to the homogeneity of distrubution of I/O.

  Kind regards
