Setting the disk ownership and access permission (DASD and FCP disks)

Edit online

For a SUSE Linux Enterprise 11, the ownership and access permission for the disks used by ASM can be set via udev rules in /etc/udev/rules.d/98-oracle.permissions.rules.

The following statements assign ownership to oracle:dba and read/write access to the disks at boot process:

KERNEL=="dasdd1", OWNER="oracle", GROUP="dba" MODE="0660"
KERNEL=="dasde1", OWNER="oracle", GROUP="dba" MODE="0660"
KERNEL=="dasdf1", OWNER="oracle", GROUP="dba" MODE="0660"
KERNEL=="dasdg1", OWNER="oracle", GROUP="dba" MODE="0660"
KERNEL=="dasdh1", OWNER="oracle", GROUP="dba" MODE="0660"
KERNEL=="dasdi1", OWNER="oracle", GROUP="dba" MODE="0660"
KERNEL=="dasdj1", OWNER="oracle", GROUP="dba" MODE="0660"
KERNEL=="dasdk1", OWNER="oracle", GROUP="dba" MODE="0660"
KERNEL=="dasdl1", OWNER="oracle", GROUP="dba" MODE="0660"
KERNEL=="dasdm1", OWNER="oracle", GROUP="dba" MODE="0660"

For the changes to take effect immediately, enter /etc/init.d/boot.udev restart or reboot the system.
