Note the following issues when connecting the ETERNUS Disk storage system to a server.

3.1 Connection Notes for PRIMERGY

• The following operation conditions are recommended to maintain storage system reliability:- Multiple paths- Use of multipath drivers which support path redundancy control

Configure a multipath environment, and select a multipath driver which supports path redundancy control to increase redundancy and reliability of the connection between the ETERNUS Disk storage systems and the server.

• LUN recognition by the Windows® plug and play function cannot be guaranteed.• The following cluster configuration is supported for Windows®:

- WSFC (Windows Server Failover Cluster) configuration- MSCS (Microsoft Cluster Service) configuration

For details on servers which support cluster configuration, consult your FUJITSU sales represen-tative.

3.2 Connection Notes for Other Companies' Industry Standard Servers

• To build a cluster configuration for Windows®, use Microsoft Cluster Service (MSCS), Windows Server Failover Cluster (WSFC), and MSCS- and WSFC-compatible applications. This cluster configuration must also use only one type of SAS card. Operation cannot be guaranteed if the cluster is configured using multiple types of SAS cards.

• LUN recognition by the Windows® plug and play function cannot be guaranteed.• The following operation conditions are recommended to maintain storage system reliability:

- Multiple paths- Use of drivers for ETERNUS Disk storage systems which support path redundancy control

Configure a multipath environment, and select a driver for ETERNUS Disk storage systems which supports path redundancy control to increase redundancy and reliability of the connection between the ETERNUS Disk storage systems and the server.

3.3 SAS Card Driver Notes

• When the same type of chip is used for both the SAS card and the server's onboard RAID or RAID card, the driver installed for the SAS card may also control the onboard RAID or RAID card.Contact the server vendor for details of how each onboard RAID or RAID card is affected by the SAS card driver.

• The ETERNUS Multipath Driver supports path redundancy control (path fail-over).For product information, refer to the following URL:

http://www.fujitsu.com/global/services/computing/storage/eternus/products/diskstorage/software/eternusmpd/

3.4 ETERNUS Disk Storage System Driver Notes

When connecting the server to the ETERNUS Disk storage system with multipath configuration,using the path redundancy control (path fail-over) function with a driver for ETERNUS Disk stor-age systems, the ETERNUS Multipath Driver is required by the server:

For product information, refer to the following URL:http://www.fujitsu.com/global/services/computing/storage/eternus/products/diskstorage/software/eternusmpd/

Even when single-path connection is used between the ETERNUS Disk storage system andserver, an ETERNUS Disk storage system compatible driver (ETERNUS device driver) is notrequired by the server.

3.5 MSCS and WSFC Notes

• To use MSCS or WSFC configuration, install the driver for ETERNUS Disk storage systems or Windows Server® 2008 standard multipath driver (msdsm) on each node (server) and check the connections before MSCS or WSFC installation.

• Check the registry values by following the instructions in "Chapter 8 Checking the Registry Information" (page 21), after installing MSCS or WSFC.

• When setting up the MSCS, a reset group must be set for the ETERNUS Disk storage system. A reset group does not need to be set for WSFC.
