    Empty ASM disk group [INS-30507]

    797369
      Hello Good people!
      I have SUSE Linux Enterprise Server 11 (x86_64) and grid infrastucture 11.2.
      I have installed ASMlib, and made
      ***********************************
      /etc/init.d/oracleasm status
      Checking if ASM is loaded: yes
      Checking if /dev/oracleasm is mounted: yes

      /etc/init.d/oracleasm querydisk ASMDISK1
      Disk "ASMDISK1" is a valid ASM disk
      **********************************

      Then i am trying install grid infrastucture, on step CONFIGURE ORACLE GRID nfrastucture for Standalone Server,
      i can`t find my Disk "ASMDISK1"

      Why grid infrastucture can`t find my Disk "ASMDISK1"?

            Hi,

            maybe wrong permissions?
            What did you use for oracleasm configure and what credentials (espially the group) did you specify during GI install?

            Regards
            Sebastian

                Hi,
                you can overwrite the header of the disk.
                #>dd if=/dev/zero of=/dev/[DISK/LUN] bs=1024k count=50
