Description Tim Wilkinson 2011-05-12 18:16:46 UTC 
Description of problem:
----------------------
Created a udev rule to apply oracle ownership as required for RAC installation with ASM without ASMlib. 



Component Version-Release:
-------------------------
udev-147.2.34.el6 x86_64
libgudev1-147.2.34.el6 x86_64
libudev-147.2.34.el6 x86_64
kernel-2.6.32.125.el6 x86_64



How reproducible:
----------------
consistent



Steps to Reproduce:
------------------
1. Create udev rules file /etc/udev/rules.d/20-oracle-asmdevices.rules using the syntax as specified in a combination of RH KB DOC-45628 [How can static names be assigned for SCSI devices using udev in Red Hat Enterprise Linux 6?] and Oracle 11gR2 Grid install documentation at http://download.oracle.com/docs/cd/E11882_01/install.112/e17212/storage.htm#CWLIN304 [Configuring Disk Devices Manually for Oracle ASM].

2. /sbin/start_udev



Actual results:
--------------
After start_udev or a reboot, the specified multipath devs remain owned by root.

Even if the ownership is changed by hand, start_udev will result in their being owned by root again.



Expected results:
----------------
After start_udev or a reboot, udev identifies the device matching the WWID specified in RESULTS= and the dev filter specified KERNEL=, assigns owner.group to oracle.oinstall 



Additional info:
---------------
Example rule attempted ...

  KERNEL=="/dev/dm-*", BUS=="scsi", 
  PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=%N", 
  RESULT=="3600c0ff0001122167ceb914d01000000", OWNER="oracle", 
  GROUP="oinstall", MODE="0660"

The KERNEL attribute filter has tried /dev/mapper/msa11_ocr, /dev/dm-18, /dev/dm-*, and the underlying /dev/sd* devs, none of which seem to make a difference.

Comment 2 RHEL Program Management 2011-05-13 06:00:48 UTC 
Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
Comment 3 Aleksandr Brezhnev 2011-05-13 16:40:08 UTC 
Please, remove BUS="scsi" from your rule and repeat the test.
Comment 4 Tim Wilkinson 2011-05-13 19:28:23 UTC 
This syntax (no BUS=, no full path to dev) seems to successfully apply disk ownership but not group membership.

KERNEL=="dm-*", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace
--device=%N", RESULT=="3600c0ff0001122167ceb914d01000000", OWNER="oracle",
GROUP="oinstall", MODE="0660"
Comment 5 Aleksandr Brezhnev 2011-05-13 20:01:52 UTC 
Rename your rule to 51-oracle-asmdevices.rules
Comment 7 Tim Wilkinson 2011-05-13 22:25:59 UTC 
(In reply to comment #5)
> Rename your rule to 51-oracle-asmdevices.rules

That resolves my issue and works very well. Thanks.
