Unable To Fix Asm Driver Permissions

by

Existing Oracle 10.2.0.5 Enterprise ASM instance on Solaris 10 x86 not finding disks suddenly after the server was restarted. Contacted the Solaris Admin and he said the disks are up and functioning with no change being made. Tried troubleshooting and ran dd command and sure enough it comes back permission denied. Admin stated the devices have always been owned by root and it was working fine as configured. I have another server with the exact same setup with root device owner and Oracle sees those disks just fine. Anyone have any ideas on what I could check? We cannot create ASM disks using the command:# /etc/init.d/oracleasm creatdisk ASMDISK1 /dev/mapper/mpathdp1Marking disk 'ASMDISK1' as an ASM disk: FAILEDThe log (/var/log/oracleasm) has the following:Clearing disk header: doneDisk 'ASMDISK1' does not exist or is not instantiatedWriting disk header: doneInstantiating disk: oracleasm-instantiate-disk: Unable to create ASM disk 'ASMDISK1': Permission deniedfailedClearing disk header: doneThe command is being executed by the root user.

The filesystem will usually go into read-only while the system is running if there is a filesystem consistency issue. This is specified in fstab as errors=remount-ro and will occur when a FS access fails or an emergency read-only remount is requested via Alt + SysRq + U. You can run: sudo fsck -Af -M.

Guide does not show me have any guidance on how to trouble shoot ASM installation error.so how should I see the log? Where should i find the log?

Which directory?thanks a lot!Edited by: oraclewannabe2 on Dec 23, 2008 10:32 AM When you run the Oracle Universal Installer the location of the installation log file is displayed on the screen. Hi all, Initially i configured ASM disks using raw devices then i created one database to store all files using raw devices.Later i installed asmlib to provide ASM disks. Hello,I am new to ASM and am having trouble getting the oracleasm to recognize my disks. I had the SA set up and present the logical volumnes as follows:root#remarkable db1# cat /proc/partitionsmajor minor #blocks name3 0 209715200 hda3 1 104391 hda13 2 209608087 hda2253 0 115474432 dm-0253 1 10223616 dm-1253 2 26214400 dm-2 Couple of things to add here:1. If you need to set ASMDISKSTRING to /dev/oracleasm/. in order to discover disks created through ASMLIB then you have set ASMLIB up incorrectly and you wont get the full benefits from it (e.g.

Reduced file descriptors), you should be able to discover the disks using ORCL:. or null, check the permissions on /opt/oracle/extapi as the oracle user.2. You shouldn't create ASM disks over a volume group - see ASM Best Practices: 265633.1ThanksPaul Thank you. That is helpful. I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2).The Virtual Disk for each VM is 20 GB whose raw device is /dev/sda (partition /dev/sda1 is the same size).I am installing Oracle 11gR2 RAC Grid using Installer whose location is: /home/./grid/runInstaller. I am on step 4 of 8 in the Wizard whose contents are as follows:Oracle Base: /u01/11ggridSoftware Location: /u01/app/gridCluster Registry Type: ASMOSASM Group: dbaWhen click 'next' button I got this error:' INS-32021 Insufficient disk space on this volume for the selected Oracle homeCause - The selected Oracle home was on a volume without enough disk space.Action - Choose a location for Oracle home that has enough space (minimum of 3,017MB) or free up space on the existing volume.

I have added a new Virtual Hard Disk (10GB) grid.vmdk into VM rac1 whose raw device is /dev/sdg and partitioned it to /dev/sdg1.My question is:How to point Oracle Home directory /u01 to the new partition /dev/sdg1 or grid.vmdk?Thanks. Hi,check if your new disk has been added succesfully. Format it and make partition on it.See for the good exampleCheers Folks,Hello.
