ORA-15018 on running asmca

Question

Receiving this error and everything looks like it should be, any ideas would be immensely appreciated. The 3 devices at the bottom are the asmdisks.

Hi,
[arqopasr29].ora11g:/home/ora11g > /opt/oracle/app/ora11g/product/11.2.0/grid/bin/asmca -silent -oui_internal -configureASM -diskString '/dev/oracleasm/disks' -diskGroupName ASM_CONF -diskList ORCL:ASM_CONF -redundancy EXTERNALYou are setting wrong disk discovery path to be used by ASM:
Your config:
-diskstring : /dev/oracleasm/disks
-diskList: ORCL:ASM_CONFYou are mixing the disk discovery path which can be configured in different ways.
1. Using /dev/oraclasm/disks/
2. Using ORCL:*
Try it:
-diskString : '/dev/oracleasm/disks/*'
-diskList : /dev/oracleasm/disk/ASM_CONFor
-diskString : 'ORCL:*'
-diskList : ORCL:ASM_CONFSecond problem:
brw-rw---- 1 ora11g oinstall 8, 17 Oct 25 13:01 ASM_CONF
brw-rw---- 1 ora11g oinstall 8, 18 Oct 25 13:01 DATADG_DISK
brw-rw---- 1 ora11g oinstall 8, 19 Oct 25 13:01 FRADG_DISKYou configured wrong OS group (oinstall) to ASMDISK. You must re-config ASMLib to OS Group 'asmadmin' or 'dba' depend which group you configured during Installation.
Hope this help,
