HP SureStore E SAN Manager LUN Management Administrator's Guide

Microsoft Cluster Server (MSCS) 155
Advanced SAN
Administration
• When using the HP SAN Manager LM QLogic HBA driver with Microsoft Cluster Server
(MSCS) in a switched environment, set the BusResetBehavior registry value to 5, which
enables bus reset operations to successfully break SCSI reservations, allowing
successful cluster failover. A BusResetBehavior value of 5 enables target reset, LIP
reset, and full login. For more information about the BusResetBehavior registry value,
see page 188.
