ASM instance: ORA-15032 and ORA-15063 errors occur after shutdown and startup

Background: Using ASM with asmlib by multipath software
The Story:
Restarted ASM instance for the first time:

[loki:oracle@+ASM] /etc/init.d >su -
Password:
[root@loki ~]# /etc/init.d/oracleasm stop
Unmounting ASMlib driver filesystem: [ OK ]
Unloading module "oracleasm": [ OK ]
[root@loki ~]# /etc/init.d/oracleasm start
Loading module "oracleasm": [ OK ]
Mounting ASMlib driver filesystem: [ OK ]
Scanning system for ASM disks: [ OK ]
[root@loki ~]# /etc/init.d/oracleasm scandisks
Scanning system for ASM disks: [ OK ]
[root@loki ~]# /etc/init.d/oracleasm listdisks
PRDWH_DATA_1
PRDWH_DATA_2
[root@loki ~]# logout

We got the following Error:

[loki:oracle@+ASM] /etc/init.d >sqlplus "/ as sysdba"

It seemed that there is something wrongly set in the way they are attaching these disks to the OS
ASMLIB is running under root user, so it shouldn't have any access issue
however, there was an access issue "error function = [asm_open], error = [1], mesg = [Operation not permitted]"

We found out how to TROUBLESHOOT asmlib problems by note 353423.1, so we used kfod

[loki:oracle] /software/oracle/ASM10gR2/bin >kfod asm_diskstring='ORCL:*' disks=all
clsc_ginit: CLSD initialization failed, rc 2, ecode 7
KFOD-00301: file not found; arguments: [2] [kgxgncin]

LEM-00033: file not found; arguments: [lempgfm] [Couldn't open message file]
LEM-00031: file not found; arguments: [lempgmh] [lmserr]

LEM-00033: file not found; arguments: [lempgfm] [Couldn't open message file]
LEM-00031: file not found; arguments: [lempgmh] [lmserr]

the problem solved after setting ORACLEASM_SCANORDER on file /etc/sysconfig/oracleasm to dm

oracleasm:
ORACLEASM_SCANORDER=dm

Good output looks like this:

[loki:oracle@PRDWH] /software/oracle >kfod asm_diskstring='ORCL:*' disks=all

  1. Looks like the Metalink note moved to 391136.1

  2. Thanks for you comment.
    Note 391136.1 is a specific solution, which answers directly to the problem.
    Note 353423.1 is teaching & leading through some scenarios.
    I liked the option of using "OSM Discovery utility" (kfod), I don't think it is documented properly.

  3. I actually meant to imply that Note 398622.1 doesn't seem to exist anymore. At least, I couldn't find it.
