We tried your suggestion, it didn't work for us.

Subject: Re: RAC -- RAW Device Multipath (Shared Storage)
I sent this to Rama earlier, but wanted to include the list:
We had similar issues on different hardware. ASMLib is looking for the
first shared path in your mpath, which is not what you want. I suggest
putting the EXCLUDE line in oracleasm as follows:
/u01/app/oracle: cat /etc/sysconfig/oracleasm
# This is a configuration file for automatic loading of the Oracle
# Automatic Storage Management library kernel driver. It is generated
# By running /etc/init.d/oracleasm configure. Please use that method
# to modify this file
# ORACLEASM_ENABELED: 'true' means to load the driver on boot.
# ORACLEASM_UID: Default user owning the /dev/oracleasm mount point.
# ORACLEASM_GID: Default group owning the /dev/oracleasm mount point.
# ORACLEASM_SCANBOOT: 'true' means fix disk perms on boot
# ORACLEASM_CLEARBOOT: 'true' means clean old disk perms on boot
# ORACLEASM_SCANORDER: Matching patterns to order disk scanning
# ORACLEASM_SCANEXCLUDE: Matching patterns to exclude disks from scan
We are planning to setup RAC with two node on Redhat
Linux. We want to use RAW devices with multipath using Hitachi 9970. We
could see shared storage from both the nodes. Cluster Verify fails with
following error message.
[oracle_at_soadbstg01 cluvfy]$ ./runcluvfy.sh comp ssa -n
Verifying shared storage accessibility
Checking shared storage accessibility...
Unable to determine the sharedness of /dev/sda on nodes:

Oracle (cvuqdisk) is looking for /dev/sd* location. RAW
Partitions are configured as /dev/oracleocr. Is there a way to bypass
/usr/sbin/cvuqdisk seems to look for /dev/sd*
trying to pass /dev/oracleocr/ocr01 doesn't seem to
Is there a way to pass an alternate device path?
