    Cannot verify the shared state for device /dev/oracleasm/disks/ASM1 due to Universally Unique Identifiers (UUIDs)

    user10643795

      Hi,

       

      I am using Virtualbox 4.2.16 on windows 7

       

      Trying to install Oracle12C GI for HA setup. My runcluvfy did not gave any error, but while "Perform Prerequisite Checks" I am getting the following error:

       

      Device Checks for ASM - This is a pre-check to verify if the specified devices meet the requirements for configuration through the Oracle Universal Storage Manager Configuration Assistant.

       

      Verification WARNING result on node: rac1  Details:

      -

      Cannot verify the shared state for device /dev/oracleasm/disks/ASM1 due to Universally Unique Identifiers (UUIDs) not being found, or different values being found, for this device across nodes: [rac1, rac2]  - Cause: Cause Of Problem Not Available  - Action: User Action Not Available

       

      Verification WARNING result on node: rac2  Details:

      -

      Cannot verify the shared state for device /dev/oracleasm/disks/ASM1 due to Universally Unique Identifiers (UUIDs) not being found, or different values being found, for this device across nodes: [rac1, rac2]  - Cause: Cause Of Problem Not Available  - Action: User Action Not Available

       

      Below are some outputs

      [root@rac1 ~]# hostname

      rac1.localdomain

      [root@rac1 ~]# oracleasm listdisks

      ASM1

      [root@rac1 ~]# blkid | grep sdb1

      /dev/sdb1: LABEL="ASM1" TYPE="oracleasm"

      [root@rac1 ~]# id oracle

      uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),501(vboxsf),54322(dba)

      [root@rac1 ~]#

       

      [root@rac2 ~]# hostname

      rac2.localdomain

      [root@rac2 ~]# oracleasm listdisks

      [root@rac2 ~]# uname -r

      [root@rac2 ~]# cat /etc/redhat-release

      Red Hat Enterprise Linux Server release 6.3 (Santiago)

      [root@rac2 ~]#

       

      Please let me know why I am getting that error for ASM disks, I have tried connecting the ASM disk to SATA and SCSI Controller but getting the same results, Please not that the disk is attached to both nodes in Virtualbox. I have tried without using the oracleasm and with udev but same issue. This time I am not using udev. I am using oracleasm

       

      [root@rac1 ~]# yum list *oracleasm*

      Installed Packages

      kmod-oracleasm.x86_64           

      oracleasm-support.x86_64        

      oracleasmlib.x86_64             

      [root@rac1 ~]#

       

       

      Help to fix this issue.

      Thanks
