I can't imagine that installing the oracle executables on
shared storage would be a good idea.
see below for an Oracle tech note.
note that the shared storage has to be "raw".
I think I recall seeing a discussion about how OPS is going
to be obsoleted and replaced by a better cluster technology.
I hope you can talk to Oracle Tech Support if you are the
one doing this. I've heard that OPS is *the* nastiest Oracle
configuration to setup.

This article documents how Oracle Parallel Server is implemented on Windows NT.
SCOPE & APPLICATION
-------------------
This document is intended for people who administer Oracle Parallel Server on
Windows NT.
Oracle Parallel Server on NT
----------------------------
1.OVERVIEW OF SYSTEM ARCHITECTURE
...
2.IMPLEMENTATION OF SHARED DISK
Oracle Parallel Server requires a shared disk subsystem to contain shared
partitions that are raw.
As Windows NT does not support a proper distributed file system, Oracle bypasses
it by using raw devices. This
allows nodes running different instances to access shared disks. Data files,
redo log files, and control files
are stored on the raw devices. The shared disks are then a collection of
unformatted raw devices.
Raw devices are created on a disk that does not have a primary partition and has
only one extended partition.
A raw partition is created when an extended partition is created and logical
drives are assigned to it without
applying any formatting. The Windows NT Disk Administrator application allows
you to create an extended partition
on a physical drive.
An Extended Partition points to raw space on the disk that can be assigned
multiple logical drives for the
database files. It avoids the four-partition limit by allowing you to define
large numbers of logical drives to
accommodate applications using Oracle on Windows NT. Logical partitions can
then be given symbolic link names to free
up drive letters. This makes Oracle Parallel Server on Windows NT more scalable.
You need to create raw devices if you are creating a database manually,or using
the Oracle Database Configuration
Assistant to create the files for the database. However, if you are using the
Oracle Database Configuration Assistant,
a precise number of raw devices must be set up.
Raw devices are created prior to installation and creating a database.
3.DLM CONFIGURATION
The Distributed Lock Manager (DLM) maintains a list of system resources and
provides locking mechanisms to
control allocation and modification of Oracle resources. Resources are
structures of data. The IDLM does not control
access to tables or anything in the database itself. Every process interested in
the database resource protected by the
IDLM must open a lock on the resource.
