ASM Disk not shown in Oracle Universal Installer (OUI) or DBCA
Terms:
Operating System: Enterprise Linux 4 U5 (RHEL4 U5)
Oracle: 10.2.0.1
Problem:
While installing the ASM Instance with Oracle Universal Installer the ASM Disk, created with oracleasm createdisk, is not shown.
Solution:
Define the Scanorder in /etc/sysconfig/oracleasm config file. For example, if the used multipathing device is /dev/md1, you have to force the ASMlib to scan the /dev/md* paths before the /dev/sd* paths.
# vim /etc/sysconfig/oracleasm # ORACLEASM_SCANORDER: Matching patterns to order disk scanning ORACLEASM_SCANORDER="md sd"
Also make sure that the needed packages are installed for using ASM with ASMlib.
Make sure that the needed packages are installed.
- oracleasmlib-2.0 – the ASM libraries
- oracleasm-support-2.0 – utilities needed to administer ASMLib
- oracleasm – a kernel module for the ASM library

PERFECT! SCANORDER FIXED IT.
I had this problem on one node of a RAC.
I discovered watching the IDs of devices(/etc/init.d/oracleams querydisk DATA1 and ls -al /dev/*) that oracleasm mounted the device on /dev/sdd1 instead of /dev/dm-2,
I was looking for a way to force the asm driver to use the multipathed device instead of one of the phisical channels, and ORACLEASM_SCANORDER did the job.
Thanks
BEFORE:
[root@prod-giboracle-002/alm-117 bin]# /etc/init.d/oracleasm querydisk DATA1
Disk “DATA1″ is a valid ASM disk on device [8, 49]
AFTER:
[root@prod-giboracle-002/alm-117 bin]# /etc/init.d/oracleasm querydisk DATA1
Disk “DATA1″ is a valid ASM disk on device [253, 6]
DEVICES IDS:
/dev/mapper: (the multipathed one, the good one!)
total 0
brw-rw—- 1 root oinstall 253, 2 Sep 27 23:59 data_1
(the phisical one, the bad one!)
