Software overview
Smart Array Multipath software delivers dual path functionality and supports failover capability for a
redundant HBA in a server with redundant cabling to an HP StorageWorks Modular Smart Array 500
Generation 2 storage system. This fault-tolerant tool enhances availability in clustering and DAS solutions
with up to two servers managing up to 2 TB of stored data.
The software supports multiple I/O paths to the same logical volumes. When a path fails, the software
moves the logical drives from the failed path to the path of the redundant HBA in the same server.
Smart Array Multipath software works differently with Microsoft® and Linux products to provide specific
features that are compatible with operating system functionality.
Software distribution
Smart Array Multipath software is included with the 4-port U320 Shared Storage Module option. Smart
Array Multipath software version 2.0B and later only contains Multipath I/O deliverables for Microsoft®
Windows® operating systems and is only available for web download from the HP website
(
).
For Linux operating systems, refer to the procedures in this guide to configure the standard Linux drivers
for multipath usage.
Minimum requirements
Be sure that your solution consists of the following hardware:
•
At least one server with two supported HBAs (Smart Array 642 adapters or future supported
adapters) with updated firmware
•
A supported operating system installed on the server or MSA500 G2 storage system
•
An MSA500 G2 storage system with the following:
•
At least one HP StorageWorks Modular Smart Array 500 Generation 2 Controller
•
A 2-Port Shared Storage Module and two SCSI cables
or
•
A 4-Port Shared Storage Module and four SCSI cables
For the latest versions of firmware, refer to the HP website (
