Hello,

I'm installing Oracle Grid infraestructure (11g R2) in a SLE11 SP0
enviorement.

And using ASM and ASMLIB how storage option.
In the screen to create the diskgroup to store OCR and Voting disks is empty
and if I try use the change discovery path to ORCL:* doesn't work.

I've configured the asmlib driver:

castorrac:~ # rpm -qa | grep oracleasm
oracleasmlib-2.0.4-1.SLE11
oracleasm-2.0.5-7.6
oracleasm-kmp-default-2.0.5_2.6.27.19_5-7.6
oracleasm-support-2.1.3-1.SLE11

castorrac:~ # cat /etc/*release
SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 0
LSB_VERSION="core-2.0-noarch:core-3.2-noarch:core-4.0-noarch:core-2.0-x86_64:core-3.2-x86_64:core-4.0-x86_64"

castorrac:~ # uname -a
Linux castorrac 2.6.27.45-0.1-default #1 SMP 2010-02-22 16:49:47 +0100
x86_64 x86_64 x86_64 GNU/Linux


And executing some testing commands seems fine.

If I use the string /dev/oracleasm/disks/ as Disk discovery path, the screen
is populated with the asm disks.
Reading some metalink note(Not up to 11G R2) say that use of this string
invalidate ASMLIB propertys.

Any know if work ORCL:* disk string in this platform or I have some issue
with the ASMLIB installation.

Many thanks
Best regards
Arturo
