Q258080: Digital Drives and Drive Letters Disappear with Clustered Server

Article: Q258080
Product(s): Microsoft Windows NT
Version(s): winnt:4.0
Operating System(s): 
Keyword(s): kbenv
Last Modified: 10-AUG-2001

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server, Enterprise Edition version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you restart your server, some Digital Array controllers may randomly lose
the shared drive in a cluster.

CAUSE
=====

This behavior can occur if the /pcilock switch is enabled on one computer but
not on the other.

RESOLUTION
==========

To resolve this behavior, enable the /pcilock switch in the Boot.ini file. Then,
shut down and then restart the computer.

MORE INFORMATION
================

The /pcilock switch prevents the hardware abstraction layer (HAL) from moving
anything on the PCI bus. The I/O and memory resources are left exactly as they
were set by the BIOS.
