1. ASMCA can not "find" the new candidate partition by "show eligible".

2. The UDEV rule seems like no problem:

cat 99-oracle-asmdevices.rules

KERNEL=="sda1",BUS=="scsi",PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent",RESULT=="360a980004430753872244b6e4a376f70",NAME="data2",OWNER="grid", GROUP="asmadmin", MODE="0660"


3. The udev device could be found with right ownership and permission:

ls -l /dev |grep data
brw-rw---- 1 grid asmadmin 8, 1 Nov 1 09:36 data2


4. kfed can read the device without problem:

$ kfed read /dev/data2

kfbh.hard: 0 ; 0x001: 0x00
