On EL/RH 5 ORACLEASM LISTDISKS not Showing Devices After Reboot or Restart

ID 558596.1

The oracleasm scans /proc/partitions and expects devices to be available in /dev. If the device doesn't exist in /dev it will fail to open the device. RHEL/OEL5 does not create dm-xx devices in /dev by default.

Please comment out the following line in file /etc/udev/rules.d/50-udev.rules

#KERNEL=="dm-[0-9]*", ACTION=="add", OPTIONS+="ignore_device"

reboot and the problem should be gone.
