Raw Devices and RHEL4

If you're using raw devices with RHEL4 you might not know that their permissions are not retained after reboot.

Solution for this is to simply edit the file:
/etc/udev/permissions.d/50-udev.permissions

If your raw disks are used for RAC voting disks or OCR for example
you could change a line containing "raw/*:root:disk:0660" to something like: "raw/*:oracle:dba:0660" and that should do the trick.
