HP supports additional high availability multi-pathing capabilities within various operating systems and
through third-party vendors, providing continuous data access from HP's RAID MSA1500 to host servers.
Options are available for servers running the Windows, Linux and HP-UX operating systems. More
information and the explanation of restrictions are available at

Microsoft Windows 2000 and 2003 (32 bit EE and 64 bit EE only)can utilize the HP MPIO Basic
Failover v1.3 for MSA Arrays, a DSM available for free download at the above site.
Linux (and SCO) industry standard failover for the MSA1500 is available at no charge within the
HBA device driver from QLogic or Emulex.
HP-UX utilizes PVLinks
NetWare, OpenVMS, Tru64 UNIX utilize native OS_based failover software

HP StorageWorks Secure Path is a family of high availability multi-pathing software products providing
continuous data access from the HP RAID Array to host servers running the Windows Server 2003,
Windows 2000, and Linux operating systems.
Redundant hardware, advanced RAID technology and Secure Path's automated failover capability are
used to enhance fault tolerance and availability. Secure Path effectively eliminates controllers, disk drives,
interconnect hardware and host bus adapters as single points of failure in the storage subsystem.
The attachment of non-Secure Path (single HBA) servers to a MSA1500 cs with dual controllers that has
servers with Secure Path (dual HBA) attached is supported where the operating system is Windows or
Netware. Users must realize that in event of a controller fail-over (failure of active controller) the single
path servers will lose access to their data on the MSA1500 cs.
NOTE:
NOTE: NOTE:
NOTE: If Secure Path for Linux is used on any node attached to an MSA1500 cs, all nodes must also
have Secure Path installed, regardless of operating systems.

NOTE: refer to http://www.hp.com/go/securepath for the latest Secure Path parameters.
