Lose Ownership and Permissions Of Target Physical Devices Pointed By Symbolic Links In /dev/rdsk (Doc ID 2727687.1)

Last updated on AUGUST 11, 2021

Applies to:

Solaris Operating System - Version 10 11/06 U3 and later
Information in this document applies to any platform.


Customer has ASM installed, and uses symbolic links in /dev/rdsk for ASM disks in their diskgroups, which must have 660 and grid:oinstall permissions. The ASM diskstring will lookup for /dev/rdsk/data*, /dev/rdsk/backup* and /dev/rdsk/oc* to read the disk header to load the disks into ASM for shared storage.

Customer runs "devfsadm -C" as a clean up operation after performing any disk removal.

The problem is that, even though with no devices removed recently, when "devfsadm -C" is executed nothing happens but when we reboot the LDOM, ONLY some linked devices are reverted to their original permissions and ownership. Not all, just a few, and the underlying devices exist.

Before reboot.
