10g RAC Install with Raw Devices

Hey Guys,

I am doing a RAC install on an x86_64 RH4 box. We are using 10.2.0.1 and
raw devices. The SAN is a MSA 1500. The issue that I am having is during
the Cluster install. The installer is complaining that all nodes can't
see the raw device location that I point it to for the OCR. I can dd
from all nodes to the device. Has anyone seen this before? Does anyone
know what test Oracle is using to determine connectivity? Are there any
other options that I should try before creating an SR?

hostName = grid0.hprsn.com
INFO: Query Returned: grid0
INFO: Calling Query fileQueries10.1.0.2.0  exists

filename = /dev/sda2/
INFO: Query Returned: true

PathName = /dev/sda2/
INFO: Query Returned: false
INFO: Calling Query cfsprereqQueries10.2.0.1.0  isOHonCFS

oraclehome = /dev/sda2/

nodeList = grid0,grid1,grid2,grid3,

localNode = grid0.hprsn.com
INFO: 
Query Exception: RuntimeException
Query Exception Class: class oracle.sysman.oii.oiil.OiilQueryException

PathName = /dev/sda2/
INFO: Query Returned: OPENFAILONDEV
SEVERE: The location /dev/sda2/, entered for the Oracle Cluster Registry
(OCR) is not shared across all the nodes in the cluster. Specify a
shared raw partition or cluster file system file that is visible by the
same name on all nodes of the cluster.

Thanks!

Todd
