Because of the risks of using servers with a single path HBA, HP recommends the following actions: • Use servers with a single path HBA that are not mission-critical or highly available. • Perform frequent backups of the single path server and its storage. Supported configurations All examples detail a small homogeneous Storage Area Network (SAN) for ease of explanation. Mixing of dual and single path HBA systems in a heterogeneous SAN is supported. In addition to this document, reference and adhere to the HP SAN Design Reference Guide for heterogeneous SANs, located at: http://www.hp.com/go/sandesign General configuration components All configurations require the following components: • XCS controller software • HBAs • Fibre Channel switches Connecting a single path HBA server to a switch in a fabric zone Each host must attach to one switch (fabric) using standard Fibre Channel cables. Each host has its single path HBA connected through switches on a SAN to one port of an EVA. Because a single path HBA server has no software to manage the connection and ensure that only one controller port is visible to the HBA, the fabric containing the single path HBA server, SAN switch, and EVA controller must be zoned. Configuring the single path by switch zoning and the LUNs by Selective Storage Presentation (SSP) allows for multiple single path HBAs to reside in the same server. A single path HBA server with the OpenVMS operating system should be zoned with two EVA controllers. See the HP SAN Design Reference Guide at the following HP website for additional information about zoning: http://h18006.www1.hp.com/products/storageworks/ san/documentation.html To connect a single path HBA server to a SAN switch: 1. Plug one end of the Fibre Channel cable into the HBA on the server. 2. Plug the other end of the cable into the switch. Figure 73 (page 151) and Figure 74 (page 151) represent configurations containing both single path HBA server and dual HBA server, as well as a SAN appliance, connected to redundant SAN switches and EVA controllers. Whereas the dual HBA server has multipath software that manages the two HBAs and their connections to the switch, the single path HBA has no software to perform this function. The dashed line in the figure represents the fabric zone that must be established for the single path HBA server. Note that in Figure 74 (page 151), servers with OpenVMS can be zoned with two controllers. 150 Single path implementation

General configuration components
All configurations require the following components:
XCS controller software
HBAs
Fibre Channel switches
Connecting a single path HBA server to a switch in a fabric zone
Each host must attach to one switch (fabric) using standard Fibre Channel cables. Each host has
its single path HBA connected through switches on a SAN to one port of an EVA.
Because a single path HBA server has no software to manage the connection and ensure that only
one controller port is visible to the HBA, the fabric containing the single path HBA server, SAN
switch, and EVA controller must be zoned. Configuring the single path by switch zoning and the
LUNs by Selective Storage Presentation (SSP) allows for multiple single path HBAs to reside in the
same server. A single path HBA server with the OpenVMS operating system should be zoned with
two EVA controllers. See the
HP SAN Design Reference Guide

To connect a single path HBA server to a SAN switch:
1.
Plug one end of the Fibre Channel cable into the HBA on the server.
2.
Plug the other end of the cable into the switch.
Figure 73 (page 151)
and
Figure 74 (page 151)
represent configurations containing both single path
HBA server and dual HBA server, as well as a SAN appliance, connected to redundant SAN
switches and EVA controllers. Whereas the dual HBA server has multipath software that manages
the two HBAs and their connections to the switch, the single path HBA has no software to perform
this function. The dashed line in the figure represents the fabric zone that must be established for
the single path HBA server. Note that in
Figure 74 (page 151)
, servers with OpenVMS can be
zoned with two controllers.
