1.扫描wwid
rh5-6
scsi_id --whitelisted --replace-whitespace --device=/dev/emcpowera

rh7
/usr/lib/scsi_id --whitelisted --replace-whitespace --device=/dev/emcpowera
2.创建udev绑定规则
touch /etc/udev/rules.d/99-oracle-asmdevices.rules

rh5-6
KERNEL=="emcpower", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$name", RESULT=="360001440000000010f0105c274db8934a", NAME=="asmdiskocr1", ACTION=="add", OWNER="grid",GROUP="asmadmin",MODE="0660"

rh7
KERNEL=="emcpower", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$name", RESULT=="360001440000000010f0105c274db8934a",SYMlink+="asmdiskocr1", OWNER="grid",GROUP="asmadmin",MODE="0660"

3.udev规则重新加载
rh5-6
udevadm control --reload-rules
/sbin/start_udev

rh7
udevadm control --reload-rules
udevadm trigger --type=devices --action=change

4.检查磁盘
ls -l /dev/asmdis*
