- Microsoft Cluster Server

SYMPTOMS
========

If you install Microsoft Cluster Server and shut down one of the nodes in the
cluster, the cluster service may fail with the following event codes in the
system event log:

- Event 1006

- Event 7023

- Event 1009

CAUSE
=====

When you shut down one of the cluster nodes, all resources should transition to
a surviving node in the cluster. If the shared SCSI bus loses termination, the
surviving node may not have access to the shared devices. As a result, the
surviving node may also fail and remove itself from the cluster -- only if the
quorum disk is inaccessible.

The cluster service requires access to a shared SCSI bus. The bus must be
terminated at all times. Some SCSI host adapters may provide termination only
while the computer has power. Thus, after powering off, termination may be lost.

RESOLUTION
==========

To alleviate this condition, supply external terminators for the bus or enable
constant termination of the adapter.

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

Incorrect cabling or termination of the shared SCSI bus may also trigger this
condition. Additionally, use of standard SCSI terminators with a Wide SCSI bus
may provide inadequate termination. Some older terminators do not terminate the
high bits on the Wide SCSI chain and may result in partial termination of the
SCSI bus. Consult your hardware vendor for proper cabling and termination.
