why "asmca" is changing ownership of disks from "oracle:oinstall" to "root:disk"?

user130038Feb 28 2014 — edited Mar 7 2014

I am preparing a new oracle server with following config:

Oracle Grid Infra 11.2.0.3 (patched to 11.2.0.3.6) - 64-bit

Oracle 11gR2 11.2.0.3 (patched to 11.2.0.3.6) - 64-bit

Platform: OEL 6.2 64-bit

VMWare Virtual Machine

Device persistence is being handled by VMWare - I am not suing ASMLib.

I have completed the installation. Here are the steps I followed:

Install GI 11.2.0.3 (OSDBA for ASM=asmdba, OSOPER for ASM=asmdba, OSASM=asmadmin)

Patch it to 11.2.0.3.6 (applied Apr 2013 PSU)

Install RDBMS 11.2.0.3 (OSDBA=dba, OSOPER=dba)

Patch it to 11.2.0.3.6 (applied Apr 2013 PSU)

I checked the permissions of the raw devices and they were:

brw-rw---- 1 oracle oinstall 8, 48 Feb 28 16:53 /dev/sdd

brw-rw---- 1 oracle oinstall 8, 64 Feb 28 16:53 /dev/sde

brw-rw---- 1 oracle oinstall 8, 80 Feb 28 16:53 /dev/sdf

brw-rw---- 1 oracle oinstall 8, 96 Feb 28 16:53 /dev/sdg

brw-rw---- 1 oracle oinstall 8, 112 Feb 28 16:53 /dev/sdh

brw-rw---- 1 oracle oinstall 8, 128 Feb 28 16:53 /dev/sdi

brw-rw---- 1 oracle oinstall 8, 144 Feb 28 16:53 /dev/sdj

brw-rw---- 1 oracle oinstall 8, 160 Feb 28 16:53 /dev/sdk

brw-rw---- 1 oracle oinstall 8, 176 Feb 28 16:53 /dev/sdl

brw-rw---- 1 oracle oinstall 8, 192 Feb 28 16:53 /dev/sdm

Now I started the "asmca" to configure the ASM Instance. Initially there were no disk-devices displayed. So I pressed the "Change disk discovery path" button. The moment I press the "OK" button, the permissions of the disks change to "root disk" from "oracle oinstall".

brw-rw---- 1 root disk 8, 48 Feb 28 17:15 /dev/sdd

brw-rw---- 1 root disk 8, 64 Feb 28 17:15 /dev/sde

brw-rw---- 1 root disk 8, 80 Feb 28 17:15 /dev/sdf

brw-rw---- 1 root disk 8, 96 Feb 28 17:15 /dev/sdg

brw-rw---- 1 root disk 8, 112 Feb 28 17:15 /dev/sdh

brw-rw---- 1 root disk 8, 128 Feb 28 17:15 /dev/sdi

brw-rw---- 1 root disk 8, 144 Feb 28 17:15 /dev/sdj

brw-rw---- 1 root disk 8, 160 Feb 28 17:15 /dev/sdk

brw-rw---- 1 root disk 8, 176 Feb 28 17:15 /dev/sdl

brw-rw---- 1 root disk 8, 192 Feb 28 17:15 /dev/sdm

Any clue?

Please help - dead line is fast approaching (Monday).

Best regards
