How can I get the mapper device permissions set on reboot? When I attempted to try this... # cat /etc/udev/permissions.d/50-udev.permissions | grep mapper mapper/mpath*:oracle:dba:0660 But it did not seem to work... # ls -l /dev/mapper/mpath* brw-rw---- 1 root disk 253, 2 Feb 26 20:56 /dev/mapper/mpath0 brw-rw---- 1 root disk 253, 5 Feb 26 20:56 /dev/mapper/mpath0p1 brw-rw---- 1 root disk 253, 3 Feb 26 20:56 /dev/mapper/mpath1 brw-rw---- 1 root disk 253, 4 Feb 26 20:56 /dev/mapper/mpath1p1 Am I doing something wrong? Is there another way to do this? Thanks, Scott
