Oracle UEK and ASMLIB not seeing volumes in OUI - missing utilities?

Question

Hello,
I recently installed Oracle Linux 5.5 from scratch and upgraded to the Oracle Unbreakable Enterprise Linux.
According to http://www.oracle.com/technetwork/topics/linux/asmlib/index-101839.html No ASMLIB driver package needs to be installed when using this kernel.  The oracleasm-support and oracleasmlib packages still need to be installed from ULN. I installed oracleasmlib and oracleasm-support using public yum. Then I used /etc/init.d/oracleasm to configuring and label the ASM disks, and also installed the oracle-validated rpm. /etc/init.d/oracleasm listdisks properly showed the ASM volumes.
However, the Oracle 11gR2 Grid installer did not see any available volumes, like it did before, nor did it when specifying the ORCL:* diskstring. The volumes started to show up in the installer after specifying "/dev/oracleasm/disks" as the diskstring.
Could it be the reason that some software or utilities from the ASMLIB package is missing, i.e. /usr/sbin/oracleasm-discover?
Thanks.
h3. Solution Summary
I was missing the oracleasmlib package, which I confused with oracleasm. The oracleasm package contains only the kernel driver, which is included in the Oracle Unbreakable Enterprise kernel (2.6.32-100.0.19.el5) and does not need to be installed.
The oracleasm-support and oracelasmlib packages are still required. If you do not have paid access to the ULN network you can install the oracleasm-support rpm from Oracle's public yum repository (http://public-yum.oracle.com/).
To install oracleasmlib you can try: rpm -ivh 'http://download.oracle.com/otn_software/asmlib/oracleasmlib-2.0.4-1.el5.x86_64.rpm'

Answer 1

Perhaps I can answer my question: The html document above outlines that oracleasm-support and oracleasmlib packages are still required.
What I installed was:
[root@ol55 ~]# yum list *oracleasm*
Loaded plugins: security
Installed Packages
oracleasm-2.6.18-194.el5.x86_64            2.0.5-1.el5       installed 
oracleasm-support.x86_64                   2.1.3-1.el5       installed 
Available Packages
oracleasm-2.6.18-194.el5debug.x86_64       2.0.5-1.el5       el5_u5_base
oracleasm-2.6.18-194.el5xen.x86_64         2.0.5-1.el5       el5_u5_baseThe */usr/sbin/oracleasm-discover* utility is part of oracleasmlib, and this package is missing.
I suppose I do not need to install oracleasm-2.6.18-194.el5.x86_64, which contains the kernel driver that is included in the UEK - which I confused with oracleasmlib.
Here is what tried to rectify the problem:
# yum remove oracleasm
- this removed
    kernel.x86_64 0:2.6.32-100.0.19.el5,
    oracleasm-2.6.18-194.el5.x86_64 0:2.0.5-1.el5,
    oracle-validated.x86_64 0:1.1.0-3.el5
# yum install kernel
# yum install oracle-validated
# yum install oracleasmlib
-> No package oracleasmlib available.But where is oracleasmlib? Reading the document above one more time: ... oracleasm-support and oracleasmlib packages still need to be installed from ULN.
Is it possible that oracleasmlib for UEK is only available with a ULN subscription?

I downloaded and installed oracleasmlib using the following:
rpm -ivh http://download.oracle.com/otn_software/asmlib/oracleasmlib-2.0.4-1.el5.x86_64.rpm
# /usr/sbin/oracleasm-discover ORCL:*
Using ASMLib from /opt/oracle/extapi/64/asm/orcl/1/libasm.so

Discovered disk: ORCL:VOLC [41929587 blocks (21467948544 bytes), maxio 256]Hopefully this will work....
